Abstract: A torque transmission unit is designed to be used in a hybrid transmission of a motor vehicle and includes a shaft configured to mechanically couple to a rotor of a rotary electric machine and a ratchet wheel for a parking lock device configured to block a rotational movement of the torque transmission unit. The rachet wheel includes teeth that, at least in part, have a greater hardness than the shaft. The ratchet wheel is rotationally fixed to the shaft rivets.

Abstract: A conveying device is located inside a clutch device to amplify a fluid flow in an axial direction, i.e. parallel to a rotation axis of the clutch device, and hence the fluid flow can be kept sufficiently great even in the moved portions of a fluid line. The conveying device can be used in clutch devices which are arranged as separating clutches in a hybrid module. The conveying device allows even the complicated fluid lines within hybrid modules to be supplied with sufficient fluid at all times. The conveying device may be arranged at least on the first or second clutch side, and hence the quantity of conveyed fluid is dependent on the rotation speed.
