Hydraulic fact actuator for automated operation of a friction clutch used in powertrain of motor car, changes rotating movement of rotor of electromotor corresponding to linear shift movement of piston and rotation speed of rotor

摘要

The hydraulic fact actuator (1) has an electromotor (3) which is operated by a piston rod (23) of the linear operated pistons (24) of a master cylinder (6) of a hydrostatic track. The rotating movement of a rotor (10) of the electromotor is changed corresponding to the linear shift movement of the piston and the rotation speed of the rotor, such that the rotor axis (r) of the rotor and the longitudinal axis (x) of the master cylinder are vertically arranged to each other. The gear box (13) is formed from the piston rod.
