An electromagnetic element for an electric machine, having multiple slots arranged in the circumferential direction of the electromagnetic element, said slots extending in the axial direction of the electromagnetic element and having an open side in the radial direction. A coil device is arranged in the slots, said coil device having winding heads on (at least) one axial end face of the electromagnetic element, and a cooling channel is formed in the slots in order to dispense heat from the coil device using a fluid. A wall element is also provided which has a first region that is arranged in the region of the winding head in the circumferential direction. and a second region of the wall element, said second region adjoining the first region and having teeth which extend in the axial direction and are arranged on the open side of the slots in the intermediate spaces between the slots in the circumferential direction.

A disconnect clutch for a drive train of a motor vehicle includes a torque transfer component with a contact region, an outer disc carrier, an application element, and a return spring. The outer disc carrier is rotationally and axially fixed on the torque transfer component, and arranged for receiving rotationally fixed and axially displaceable friction discs arranged for torque transmission with counter friction discs. The application element is for axially displacing at least one of the friction discs for a frictional connection and the return spring is for releasing the frictional connection. The return spring contacts the application element, the return spring comprises a radially outer portion that bears against the contact region, and the contact region is designed to modify a preload of the return spring.

A separating clutch for a drive train of a motor vehicle includes a torque forwarding component, an outer multiple disc carrier fixed to the torque forwarding component for conjoint rotation, a first plurality of friction discs, a second plurality of friction discs arranged to transmit torque through a non-positive connection with the first plurality of friction discs, a pressing element having a first side facing the friction discs and a second side, opposite the first side, facing away from the friction discs, and a restoring spring. The pressing element is for axially displacing a one of the first or second plurality of friction discs to realize the non-positive connection, and the restoring spring contacts the pressing element for canceling the non-positive connection. The restoring spring engages through and behind the first side from the second side in a positively locking connection with the pressing element.

A clutch device for a motor vehicle drive train includes an input shaft, a first clutch arranged on the input shaft, a housing wall, a support bearing on the housing wall, an actuating force introduction mechanism, and a first actuating unit. The first clutch has a first clutch component with a carrier and a second clutch component. The first clutch component is directly connected to and axially supported on the input shaft. The actuating force introduction mechanism is rotationally fixed to the first clutch component such that an actuating force which adjusts the first clutch from its open position into its closed position is introduced directly into the input shaft via the carrier and is supported by the input shaft via the support bearing. The first actuating unit is operatively connected to the first clutch and includes a movable actuating bearing arranged to interact with the actuating force introduction mechanism.
