Abstract: A method for adapting a biting point pressure of a hydraulically actuated hybrid disengaging clutch arranged in a hybrid drive train of a motor vehicle between an internal combustion engine and an electric machine includes step by step implementation during driving of the motor vehicle via a plurality of selected engagement operations of the hybrid disengaging clutch with a manipulation of a rapid filling routine. Proceeding from an initially stored biting point pressure, a setting pressure, which is reduced relative to a subsequent rapid filling routine, is incrementally increased step by step. An actual value, which is set in each case for a test parameter, is detected until the actual value corresponds to a setpoint value. A change in the transmission of torque of the hybrid disengaging clutch is derivable via the actual value.

At the end of each cantilever a post can extend downward that is configured to receive bearings and gears. A plate can comprise a hole for each post in the carrier. When the plate is coupled to the carrier it can hold the bearings and gears in place and provide added strength to the carrier. The strength benefits are large compared to the light weight of the carrier (with plate) apparatus.
