Pinion and Sleeve

The transmission is based on the operation of several pairs of pinions and sleeves producing different transmission ratios. The gear transmission ratios transmit the torque coming from the engine to the wheels, while keeping the engine speed.

When changing the gear, the shift lever, operated by the driver, pushes one of the sleeves which mesh with the right pinion. The performance of the mechanism depends on the precise manufacturing of both components – pinions and sleeves.
