Advanced Steering Systems for Skateboards

Skateboard with hydraulic steering and braking mechanism that allows the user to tilt the wheels and apply brakes by shifting weight without kingpins or bushings. The skateboard has steerable wheel assemblies with hydraulic cylinders, pistons, and brake pads. Weight shifting lowers the cylinders to move the brake pads away from the wheels for turning. Lifting weight raises the cylinders to bring the brake pads back for braking. This allows simple, intuitive steering and braking without complex components.

A device that provides improved foot stability on a one-wheeled electric board for better control, jumping and carving. It attaches to the front and/or rear edges of the board and has flanges that contact the sides of the rider's feet. This prevents foot slippage and allows leverage to steer, jump and maneuver the board better than the standard footpads.

Gravity steering mechanism for skateboards that provides stability, prevents wobbling, and simplifies maintenance compared to conventional gravity steering setups. The mechanism has an anti-falling component at the top of the steering structure to prevent oversteering. The steering structure itself has connecting plates on either side with dampers at the bottom and top. The plates have sliding grooves close to the steering structure. The anti-falling component has components like circular plates, square grooves, a rotating part, and a torsion spring. This setup allows the steering structure to rotate with gravity while preventing excessive movement and preventing falling off the skateboard frame.

A steering mechanism for skateboards that provides improved turning flexibility and smoothness. The mechanism involves using two sets of abutments and rollers on the skateboard bridge that connect to a central pivot point. When the skateboard turns, the rollers deflect relative to the lower abutment, which rotates around the pivot point. This allows more deflection and cornering compared to traditional skateboard steering where the bridge pushes against fixed rollers.

Flexible steering skateboard truck that allows smaller turning radius and improved steering flexibility compared to traditional skateboard trucks. The truck has a base, an axle frame, and an engaging member between them. The engaging member is elastically connected to both the base and the axle frame. When turning force is applied, the engaging member deflects relative to the base and axle frame to steer the axle frame. This allows the axle frame to deflect more compared to fixed bushings, reducing turning radius and improving steering flexibility.

A steering-sensitive skateboard bogie with higher steering sensitivity compared to traditional solutions like torsion spring bogies. The bogie has a base and an upper part that rotate relative to each other for steering. Instead of a fixed torsion spring, the base and upper part are connected by an elastic band. This allows faster steering response compared to a torsion spring as the elastic band stretches more easily. The elastic band provides enough resistance for steering without requiring excessive force. It also simplifies assembly compared to drilling and bolting like a torsion spring.

A skateboard truck design with improved steering stability and turn response compared to conventional skateboard trucks. The truck uses a linear damping mechanism instead of coil springs to absorb impacts and provide resistance during turns. The linear damping mechanism has a fixed amount of damping force that does not rely on spring deformation, avoiding issues like pre-compression loss and creep. It consists of a linear damping rod with a piston that moves inside a fixed cylinder. The rod connects the truck axle frame to the skateboard deck. The piston has a linear damping element like a shock absorber to provide resistance when the deck rotates. The linear damping mechanism provides consistent damping force throughout the turn range and eliminates the need for pre-compression or tightening to overcome virtual positions.

Skateboard wheel frame structure that allows smooth and stable steering using body weight. The frame has a platform fixed to the skateboard and a swing part connected by a pivot. The pivot uses needle bearings to support the rotation in both axial and radial directions. This allows the swing part to turn left/right and return to center using a spring. The needle bearings prevent binding when forces are applied perpendicular to the pivot axis. The weight-activated spring return helps stabilize steering.

Skateboard wheel frame that allows easier turning and steering compared to traditional skateboards. The frame has a base that attaches to the skateboard deck and a rotating wheel axle bracket. A spring connects the base and axle bracket. When the rider turns the deck, the spring compresses as the base deflects relative to the axle bracket. This allows the wheels to turn without the pulleys falling off due to ground friction. The spring then forces the axle bracket to rotate back to align with the base for steering reset.

Skateboard wheel frame that allows improved steering and turning compared to conventional frames. The frame has a base connected to the skateboard and an axle bracket for the wheels. The base and bracket can pivot relative to each other using a steering assembly. This allows the wheels to turn more freely as the skateboard steers, preventing wheel bind. The steering assembly has a mounting rod on the bracket, a connecting piece pivoting on the base, and a spring pressing between them. When the base pivots, the spring compresses to steer the bracket.

Skateboard with a multi-stage acceleration drive mechanism, rebound pedals, and a brake to improve performance and convenience over traditional foot boards. The skateboard has two sets of rebound pedals, one at the front and one at the rear. Stepping on alternating pedals provides power to a multi-stage acceleration drive mechanism that connects to the wheels. This allows the user to push off with one pedal and then the other to propel the skateboard. A brake assembly between the pedals allows foot braking. The drive mechanism uses a swing arm connected to a curved beam that extends to the wheels. This allows gravity to self-rotate the swing arm and drive the wheels. An inertia gear provides variable speed.

A skateboard suspension system that allows a skateboard to mimic the pumping and carving motion of surfing. The skateboard suspension has a rocker arm attached to a roller that can vertically move up and down on the skateboard. This vertical movement is cushioned by an elastic element. The skateboard truck has a rotation element that allows the suspension to rotate on the board. This allows the skateboarder to pump and carve the board like surfing by rocking their weight. The suspension also has a damping element to control rotation. This skateboard truck provides a more surf-like riding experience compared to conventional trucks.

Skateboard trucks with improved turning characteristics that allow carving and simulate surfing without wheel bite or tightening the trucks. The trucks have internal compression and recoil mechanisms that allow the trucks to rotate more freely when turning. This is achieved by having a hollow housing with an integral bushing inside. The hanger rotates on the bushing, and turning force compresses the bushing. Removing the turning force allows the bushing to expand and the hanger to return to neutral.

Skateboard design that allows sliding and turning like a snowboard, providing a different skateboarding experience. The skateboard has a deck with front and rear wheel sets. The front wheels are mounted in rotatable frames while the rear wheels are fixed frames. This allows the front wheels to turn independently when the rider tilts the board to change direction. The rotatable front frames enable sliding on the outer edges of the wheels, similar to a snowboard's edge turns. The fixed rear wheels provide stability. The rotatable front wheel frames allow the front wheels to rotate in the new direction. This allows the rider to change direction by tilting the board, just like a snowboard. The rotating front wheels also enable sliding turns on the outer edges of the wheels. The skateboard has a deck with front and rear wheel sets. The front wheels are mounted in rotatable frames while the rear wheels are fixed frames. This

Steering device for electric skateboards that improves turning flexibility compared to prior art designs. The steering mechanism has a rubber compression shock absorber between the steering dampers and the skateboard body. This shortens the steering linkage length and allows greater steering angle without increasing board length. The rubber compresses on turns to absorb shock and reduce turning radius. It expands when straightening, returning to original position. The shorter linkage and shock absorbing rubber improves turning agility.

A skateboard with independent suspension and steering for each wheel that allows the wheels to travel up and down independently from turning the board. The suspension uses a rotating support frame, upper and lower suspension arms, knuckle, spindle, and spring. The steering uses a fixed crank, tie rods, and ball joints. The suspension and steering are isolated so the suspension doesn't affect steering. The board turns by rotating the support frame while the wheels stay parallel. This allows independent wheel suspension travel without affecting steering stability.

Skateboard truck with adjustable torsional stiffness to allow customization of the skateboard's responsiveness and feel. The truck has a fork-shaped arm with compliant tongs that flex relative to each other. An axle goes through the holes in the tongs, with wheels on the outside. A stop spacer prevents excessive tongue deflection. To adjust stiffness, clamping the wheels compresses the axle and tongs. Adding or removing spacers between the wheels changes the distance and loading. This allows fine-tuning the torsional stiffness by adjusting the axle preload.

A skateboard axle assembly with a connection plate to mount the axle to a skateboard deck and a wheel axle with wheels. The axle has articulated arms that allow the wheels to pivot and tilt on the axle. This creates a four-bar linkage mechanism that enables the wheels to turn and lean independently for tight turns. The articulated arms are supported with pivot pins on the wheel axle and connection plate. This allows precise turning ability and pumping motion to propel the skateboard without pushing off the ground.

Suspension system for skateboards that allows riders to leverage their body weight to actively adjust the suspension and provide a more customizable and responsive ride. The system uses angled suspension members that attach between the skateboard deck and wheels. When the rider leans back or sideways, the angled suspension compresses, lowering the wheels. Leaning forward extends the suspension, raising the wheels. This allows the rider to proactively fine-tune the suspension based on their body position, providing a more dynamic and engaging ride experience. The suspension members also increase vertical clearance between the deck and wheels compared to direct mounting.

A skateboard that provides greater freedom of movement, stability, and turning ability compared to conventional skateboards. The skateboard has a unique front truck design that allows the front wheels to pivot and move independently from the truck base. This allows the front wheels to freely move forward or backward relative to the truck, providing a wide range of dynamic movement from the front end of the skateboard. The rear truck is mounted to the board like a regular skateboard. This allows the skateboard to turn and carve like a surfboard by pivoting from the rear. The front truck's independent wheel movement enables turning and maneuverability without tilting the board. It also allows the skateboard to be pushed forward from a dead stop without pushing off the ground. The front truck's pivoting action captures the feel of a surfboard's keel, while the rear truck provides stability.

Steerable skateboard that allows turning by shifting weight laterally instead of turning the front truck. The skateboard has an elongated pedal with pulleys at the ends. A fixed shaft connects the pulleys. Steering is achieved by leaning laterally on the pedal, which moves the pulleys and turns the shaft. This allows turning without requiring separate front truck turning components. The simple design provides improved steerability and easier operation compared to conventional skateboards. The pedal weight displacement is transmitted through pulleys and a fixed shaft to steer the skateboard.

Self-balancing skateboard with improved balance and maneuverability compared to traditional single-wheel boards. The skateboard has two parallel wheels on each side of the chassis instead of a single center wheel. This provides four contact points with the ground for better stability and allows the rider to control left/right balance separately from forward/backward balance. An elastic reset device keeps the pedals parallel to the chassis when not in use. An angle sensor detects pedal rotation. A controller uses this data to balance the skateboard and enable features like hovering in place and turning without moving forward.

Skateboard truck adapter that improves maneuverability and turning ability by adding a pivoting plate between the truck and the skateboard. The pivoting plate has a smaller pivot angle than the base plate, allowing the truck to turn more easily and rapidly. The plate also tilts on flexible members to absorb shock and dampen vibrations. This provides a smoother ride and more agile turning compared to using the truck directly on the skateboard. The adapter can be easily installed on existing trucks and decks.

Skateboard trucks with internal springs that compress when turning and recoil when released, providing a more stable and controllable ride compared to traditional skateboard trucks. The internal springs allow the trucks to turn with less effort and prevent wheel bite when carving, without needing tightened trucks or deck spacers. The springs compress as the trucks turn and expand when released, returning the trucks to neutral. This improves stability and control at speed and during turns. The trucks can be used on regular skateboards with a front kick. The internal spring mechanism replaces the need for tightening trucks or adding spacers to prevent wheel bite.

A powered skateboard that can replicate the lateral sliding movement of a snowboard on flat terrain. It uses an omnidirectional rotating roller assembly with elastic biasing along with powered trucks and a ducted fan for propulsion. The rotating roller assembly provides lateral sliding capability similar to a snowboard. The powered trucks and ducted fan provide forward propulsion. The elastic biasing helps maintain contact with the ground during turns.

A skateboard with steering mechanism that allows easy and intuitive control by tilting the board like a normal skateboard but also allows leaning to turn like a snowboard. The steering mechanism pivots the front and rear wheel axles around a vertical axis when the board is tilted. This allows the board to be used like a regular skateboard by keeping it upright, or it can be leaned like a snowboard for turning by tilting the board sideways. The axles pivot up and down instead of side to side, which provides better stability and control compared to traditional skateboards that have side-to-side wheel tilting.

Double-kingpin skateboard truck with adjustable turning and stability for improved safety and performance. The truck has a keyway slot in the intermediary member and an L-shaped keyway bolt. Riser washers can be added between the base plate and intermediary member to adjust the height. This allows tight turning for tricks like slalom and sidewalk surfing, or higher for stability at speed. The keyway prevents the kingpin from rotating in the intermediary member, preventing metal-to-metal contact and breakage.

A four-wheel skateboard with improved stability and steering compared to traditional two-wheel skateboards. The skateboard has two steering devices, one at the front and one at the rear, each with two wheels. The wheels have rotating seats that pivot around a front axis. The seats have frames that can yaw or rotate relative to the board. This allows the board to twist around its longitudinal axis when the user turns. The pivot position is forward of the wheel frame rotation axis, so the board deforms first. This prevents the wheels from offsetting the user's turn force. The pivot seats also have restoring springs to return them to center.

Four-wheeled skateboard with improved stability and steering compared to conventional two-wheeled skateboards. The skateboard has a central board with steering devices at the front and rear, each having two wheels. The front and rear steering devices have a rotating wheel seat that pivots downwardly from the board and a swinging wheel rack that attaches to the wheel seat. The rotation axis for the wheel seat is angled with the rotation axis for the wheel rack, so the wheel seat rotates further than the wheel rack when the board tilts. This provides more leverage for steering. A restoring mechanism between the board and wheel seat provides tension as the wheel seat rotates. This helps return the wheels to center when the board levels out.

Skateboard steering mechanism with integrated scull and multiple links that provides sensitive and large angle steering. The mechanism has a lock frame, connecting rod set, scull group, center rod group, and wheel sets. The lock frame attaches to the pedal and has a pivoting center rod. The connecting rod set attaches to the lock frame and pivots on the center rod. The scull group connects to the lock frame and connecting rod set. The wheel sets attach to the ends of the connecting rod set. Applying force to the pedal turns the scull, connecting rods, and wheels for steering. The integrated scull and multiple links provide sensitive, large angle steering compared to conventional skateboard steering mechanisms.

A skateboard steering mechanism with a compact, integrated design that allows a joystick-style steering input. The mechanism uses a multi-link structure with a locking frame, connecting rods, a central rod, and rockers. The joystick motion is translated into steering through pivoting connections between the links. The central rod pivots in the locking frame and connects to the end links. The rockers pivot on the locking frame and connect to the middle links. This allows tilting the joystick to steer the skateboard. The links can be compressed to provide limited swing steering as well. The mechanism avoids the complexities of rocking wheels or separate linkages while providing a compact, integrated steering solution for skateboards.

Skateboard with increased steering angle to allow easier turning for beginners. The skateboard has a steering enhancement device in addition to the existing steering mechanism. This device consists of a rotating cylinder with collared ends for attaching the front and rear steering shafts. The cylinder is mounted on a base with a gear ring. The front and rear pedals each have sleeves with sockets. The free ends of the steering shafts slide into these sockets. This allows the pedals to pivot independently while the shafts rotate around the cylinder. This provides much larger turning angles compared to the conventional skateboard steering.

A skateboard truck with dual modalities of use, as either a conventional skateboard truck or a more maneuverable caster truck, by using a sliding lock to disable movement about one axis. The truck has a baseplate, caster arm, hanger, and releasable locking mechanism. The lock allows the caster arm to rotate freely for conventional truck use, or slide into position against the baseplate to prevent rotation and enable the caster truck mode. This provides the benefits of both truck types without the drawbacks like mechanical stress or specialized components.
