Tire Balancing Machine: Precision Wheel Alignment

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.

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.

Balancing vehicle wheels using a single weight to reduce static imbalance and vibrations. The method involves finding the correct axial position inside the wheel rim for a single balancing weight to cancel static imbalance. By measuring the rim profile and using an indicator to determine the weight's position, it allows balancing with a single weight instead of two. This reduces the number of balancing steps and saves time. The single weight placement also provides a lower static imbalance compared to using two weights.
