Hydraulic device for e.g. bicycle, has hydraulic pump provided with rotor mounted in pump casing, connection unit for connecting pedals of vehicle to rotor, and varying unit varying rate of pump for constant rotation speed of rotor

摘要

The device has a hydraulic pump (100) including a rotor (102), with blades (104), mounted in a pump casing (101), and a connection unit (130) for connecting pedals of a vehicle to the rotor. A clamping jaw and a column nut rigidly connect the casing to a frame or chassis of the vehicle. A fluid connection unit provides fluidic connection between the pump and a hydraulic motor to establish a closed circulation circuit of a transmission fluid between the pump and the motor. A varying unit (110) varies the rate of the pump for a constant rotation speed of the rotor.
