An actuator and clutch assembly for a power transmission device includes a first and second clutch members arranged to selectively define a connected state of the clutch when the second clutch member is drivingly engaged with the first clutch member and a disconnected state of the clutch when the second clutch member is not drivingly engaged with the first clutch member. An electric motor drives an input member driven for rotation about an axis, and an output member is driven axially relative to the input member when the input member rotates, wherein the second clutch member moves axially with the output member. A spring provides a force on the output member that biases the output member in a direction in which the second clutch member is moved toward the first clutch member. The spring is radially and axially overlapped by the input member and the output member.

Rotary power transmission device with clutch

An electric drive can comprise a housing assembly; an electric machine with a hollow shaft; a planetary gearing; and a power distribution unit having an input part and two output parts, the input part being connected to the planet carrier, one of the output parts being connected to an intermediate shaft extending through the hollow shaft; wherein the housing assembly comprises a motor-sided first housing part, a gearing-sided second housing part, and an intermediate housing part disposed therebetween, wherein the intermediate housing part includes, integrally formed, an intermediate wall, a motor-side jacket portion and a gearing-side jacket portion, wherein a sealed cavity for a coolant flowing therethrough is formed between an outer face of the motor-side jacket portion and the inner face of the first gearing part.

Electric drive with cooling

A dual clutch unit for variable torque distribution to two output shafts comprises: a clutch input part rotatably drivable about an axis; a first disk pack for transmitting torque from the clutch input part to a first clutch output part, wherein the first disk pack is axially loadable by a first pressure plate and is axially supported against the clutch input part via a first intermediate plate; a second disk pack for transmitting torque from the clutch input part to a second clutch output part, wherein the second disk pack is axially loadable by a second pressure plate and is axially supported against the clutch input part via a second intermediate plate; wherein the first intermediate plate and the second intermediate plate are axially arranged between the first disk pack and the second disk pack and are axially engaged with each other such that they are axially supported independently of each other against the clutch input part.

Dual clutch unit with electric drive

An electric drive for driving a motor vehicle comprises a housing assembly; an electric motor having a motor shaft provided in the form of a hollow shaft which is rotatingly drivable around a rotational axis A and which is connected to a drive gear; a transmission unit having at least one transmission shaft which is rotatingly drivable by the drive gear and having at least one output shaft, the output shaft extending through the hollow shaft; wherein between the hollow shaft and the output shaft an annular channel is formed, having a first opening facing the transmission unit and a second opening facing away from the transmission unit; wherein the housing assembly comprises a lubricant-guiding geometry that is configured to guide lubricant into a mouth region of the first opening of the annular channel, so that the lubricant can flow through the annular channel to the second opening.

Electric drive

A dual clutch arrangement for a transmission that is provided with a first input shaft and a second input shaft has a clutch housing that is connectable to a drive train in a rotationally fixed fashion. The first and second friction clutches can transmit a torque between the clutch housing and the first and the second input shafts, respectively. The first and second friction clutches are nested in the radial direction with respect to each other and actuated by a first and a second actuating unit that have pistons for pressuring clutch disk packs. The compressive force exerted by the piston of the first actuating unit and the compressive force exerted by the piston of the second actuating unit are directed in axially opposite directions with respect to each other.
