Abstract
A compact hybrid module includes a separating clutch with a reliably controlled actuation pressure. The hybrid module is provided with a disengagement device having a pressure pot for the transmission of force from a disengagement bearing to a pressure plate of the separating clutch or K0 separating clutch. The separating clutch itself can be actuated via the pressure pot without an additional lever ratio. Owing to a low level of hysteresis as a result of the direct actuation, the clutch can then be precisely regulated in terms of pressure.

A hybrid module for a drivetrain of a motor vehicle comprising:
- a rotor element arranged to be driven by an electric machine;
- a separating clutch arranged within the rotor element;
- a disengagement device for actuating the separating clutch;
- and
- a leaf spring, wherein:
- the separating clutch includes a pressure plate;
- the disengagement device includes a piston, a disengagement bearing and a pressure pot;
- the piston is for transmitting a force to the disengagement bearing;
- the disengagement bearing includes a roller element entirely radially inside of the piston;
- the pressure pot is for transmitting the force from the disengagement bearing to the pressure plate without a lever action;
- the rotor element includes a rotor web;
- and
- the leaf spring connects the pressure plate to the rotor web.
