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.

Skateboard with a single-wheel truck that improves ride comfort and performance compared to traditional four-wheel skateboards. The single-wheel truck provides a smoother ride by reducing the number of wheel impacts when crossing cracks in the ground. The single wheel also has a V groove for grinding rails without damaging the skateboard. The skateboard can have an internal motor in the wheel for powered versions.

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.

Compact and versatile suspension system for skateboard-style electric vehicles that allows optimizing motion characteristics for different vehicle types. The suspension uses threaded links, screw motors, and camber adjustment to mimic traditional suspensions. The links are moved by rotating screws driven by motors. The links and rail contact can be adjusted by magnets and springs. This allows independent camber adjustment for each link. The steering links also have magnets and springs to engage/disengage the rail. The links, motors, and rail housing compactly fit within the skateboard platform.

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 truck frame design with improved steering stability by using a cylindrical needle bearing to support the pivot axis. The bearing allows smooth rotation of the truck when weight is applied in different directions, preventing unwanted friction and improving steering response compared to plain bearings. The needle bearing supports the pivot shaft radially, in addition to the thrust direction, to better handle loads from body weight changes.

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.

Suspension system for electric skateboards that provides better ride quality and durability compared to conventional skateboards. The suspension system has symmetrical top and bottom suspensions on either side of the skateboard deck. The top suspension has adjustable sub-suspensions connected by a rod. The bottom suspension attaches to the deck and axle using bolts. This setup allows the wheels to compress over bumps without harsh impacts. The adjustable top suspension allows fine-tuning of the ride quality. The symmetrical design provides balanced suspension performance and reduces weight compared to unsymmetrical setups.
