Four-joint-rear wheel-pinion for single track bicycle, has velocity pole path provided in area of sprocket wheel of bicycle and determined for spring deflection movement of rear wheel

摘要

The pinion (1) has guiding levers (4, 5) arranged between joints (6, 7) of a frame of a single track bicycle and the corresponding joints of the rear wheel pinion of a single track bicycle, where the guiding levers guide the rear wheel pinion of the bicycle. A velocity pole path (20) is provided in the area of a sprocket wheel of the bicycle and is determined for spring deflection movement of the rear wheel.
