Tire Balancing Machine: Precision Wheel Alignment

Method for applying a sealant layer to the inner surface of a tire to improve the tire's balance. The method involves identifying balance light spots on the tire's sidewalls, determining starting and ending locations for the sealant bead based on the balance spots, and applying the sealant bead in a spiral pattern starting at the first spot and ending at the second spot. This helps balance the tire by counteracting any weight imbalances between the sidewalls.

Bias tire dynamic balancing machine that provides stable tire installation for accurate balancing results. The machine has a unique tire mounting mechanism that securely holds the bias tire during dynamic balancing. The tire is mounted on a rotating assembly with a locking handle that threads onto the assembly. This allows the tire to be tightly resisted by the assembly as it rotates, preventing excessive tire wobble during balancing. The machine also has a tire fastening mechanism inside the tire that can tighten the tire onto the resisting block. This improves tire grip and stability during balancing.

Automated system for changing tires on vehicles without lifting them. The system uses robots to perform all tasks involved in tire changes, from removing and installing tires to balancing them. The robots have end effectors that can grip and manipulate tire components like wheels and balancing weights. They are mounted on frames that attach to the vehicle chassis. The robots can move the effectors around the tire to access different locations for tasks like balancing. Sensors resolve the tire position relative to the robot reference frame. This allows the robots to precisely apply weights to specific locations on the wheel rims for dynamic balancing while the vehicle is stationary. The robotic system enables one technician to simultaneously change multiple tires on multiple vehicles without lifting them.

Track-type automobile tire balancing machine that can be mounted inside vehicles or in tight spaces. The balancer has a movable trolley that slides on a fixed guide rail with load wheels. The trolley holds the balancer and can move in and out of the vehicle. The guide rail has front and rear baffles that enclose the rail opening. This allows the balancer to be fully accessed from inside the vehicle without protruding out. The trolley has linear guides that attach to the rail ends. This enables smooth sliding motion inside the rail enclosure. The rail perforations allow the guides to pass through. The baffles and enclosed rail prevent the balancer from hanging out when inside the vehicle.

Balancing an assembly of a wheel and a tire to reduce vibrations and improve ride quality. The balancing method involves measuring the radial force variation (RFV) of the tire and marking the maximum value position. It also measures the inner and outer running errors of the wheel and synthesizes them. Then it marks the minimum value position of the synthesized waveform as the wheel balance reference. Finally, the tire and wheel balances are aligned to have the same phase. This reduces the assembly's vibration.

Balancing machine for vehicle wheels that eliminates the need for a physical gauge to measure wheel dimensions. The balancing machine has a built-in laser pointer that automatically measures wheel dimensions using triangulation instead of a physical gauge. This allows for accurate and contactless measurement of wheel geometry without requiring an operator to manually enter values. The laser pointer is mounted on the machine and has an optical system to calculate distances. This allows the machine to automatically acquire wheel dimensions during balancing instead of relying on operator input. This removes the need for a separate gauge and improves accuracy and ergonomics compared to traditional gauges.

A method for balancing a wheel without removing it from the vehicle using an on-board balancing device. The method involves lifting the wheel off the ground using a separate lifting platform or jack, determining the optimal position for the balancing weight using an on-board sensor, and attaching the weight at that position. The wheel can be rotated manually to determine the imbalance and the weight position. The sensor data is evaluated to calculate the weight location. The sensor is mounted externally on the rim before the tire is fitted. This allows balancing without needing a separate balancing machine or removing the wheel from the vehicle.
