Title: ACTUATOR FOR ACTUATING A CLUTCH, AND TORQUE TRANSMISSION TRAIN
Abstract:
The invention relates to an actuator (1) for actuating a clutch, comprising a drive element (10) which is displaceable in translational fashion, in particular a spindle of a spindle drive, and comprising a piston (110) of a piston-cylinder unit (100), wherein the drive element (10) is mechanically coupled to the piston (110), and the actuator has a radial projection (21) on that end (12) of the drive element (10) which faces toward the piston (110). The actuator furthermore comprises a shell unit (40) which is assembled from multiple individual shells (41, 42) and which is connected to the piston (110) and which encloses the radial projection (21) axially at least in sections and radially at least in sections. The invention also relates to a torque transmission train. With the actuator proposed here, a connection of a hydraulic piston to a linear drive is made possible which is expedient in terms of stresses and which is simple in terms of construction and manufacturing and which at the same time realizes radial play compensation.
