The invention provides a hydraulic transmission device for a bicycle and relates to a speed change mechanism for a bicycle or motorcycle. The hydraulic transmission device comprises a vane motor unit and a variable vane pump unit, wherein the vane motor unit is arranged at one end of an outer shell main body; the variable vane pump unit is arranged at the other end of the outer shell main body; the vane motor unit comprises a stator of a vane motor; an eccentric rotor is arranged in an circular ring of the stator; a through slot is uniformly formed along the radial direction of the rotor; a blade is arranged in the through slot and is capable of sliding along the radial direction; the axial length of the rotor is equivalent to that of the blade; pressure oil entering from an oil inlet drives the rotor eccentric relative to the stator to rotate so as to realize power output; the variable vane pump unit comprises a stator of a variable vane pump capable of directionally sliding. The hydraulic transmission device is high in torque transmission, is capable of statically adjusting and changing speed and is quick in speed adjustment; a convenient transmission is supplied for batch matching production of bicycles and refitting of existing bicycles; a large application scope can be brought to the bicycle market.
Description
technical field [0001] The invention relates to a bicycle or a motorcycle transmission device, in particular to a bicycle hydraulic transmission device. Background technique [0002] The effect of the bicycle speed change system is exactly to change the speed of the vehicle by changing the cooperation of the chain and the gear discs of different front and rear sizes. The size of the front chainring and the size of the rear chainring determine how hard the bike spins the pedals. The larger the front chainring and the smaller the rear chainring, the harder it is to pedal. The smaller the front chainring and the larger the rear chainring, the easier it is to pedal. According to the ability of different riders, the speed of the bicycle can be adjusted by adjusting the size of the front and rear chainrings, or it can cope with different road sections and road conditions. The disadvantage is that the speed cannot be changed when it is stationary, and it is troublesome to adjust...
