HYDROSTATIC ACTUATOR AND ARRANGEMENT OF A HYDROSTATIC ACTUATOR IN A MOTOR VEHICLE

摘要

The present invention relates to a hydraulic actuator (1) comprising a housing (2) and a master cylinder (31) comprising a piston (34) which is axially movable in the housing and which pressurizes a pressure chamber (33) And an arrangement structure for fixing the refueling actuator to a receiving part, wherein the piston includes a stator (24) and a rotor (23) having a rotor, And is driven by the gear device 26. According to the present invention, the bearings of the planetary gear unit are simplified, and in some cases, provided with an electronic controller Cooling and shielding and their pressure behavior are improved.
