Kupplungsbetätigungssystem

摘要

The invention relates to a clutch actuation system for actuating a dual clutch of a vehicle. Said clutch actuation system is composed of two part clutches which are actuated by two engagement bearings which are loaded by means of pressure and are arranged coaxially with respect to one another. Here, the first engagement bearing is connected to an annular piston which is arranged coaxially with respect to a transmission input shaft in a housing and is guided in the housing. The second engagement bearing is actuated by a piston which is arranged outside the housing and is operatively connected to the end of an actuating element. Said actuating element is configured at the other end as a fork, the two arms of which act diametrically on the second engagement bearing. According to the invention, at least one second piston is arranged in the housing radially outside the annular piston and acts on an actuating element within the surface of the latter.
