Abstract:
1. A drivetrain comprising a friction clutch for decoupling a transmission from an internal combustion engine having an input part, at least one output part that can be decoupled from the input part and at least one disengagement device, the at least one output part in the force-free state being decoupled from the input part and, by means of the at least one disengagement device, being brought into frictional engagement with the input part, and the at least one disengagement device being formed of a master cylinder and a slave cylinder that is in operative connection with the master cylinder via a hydraulic line, wherein in the hydraulic line between the master cylinder and the slave cylinder is a pressure relief device that sets back a pressure applied between the master cylinder and the slave cylinder when actuated, wherein the pressure relief device is operable by the driver via an actuating device.
