A drive arrangement for a motor vehicle comprises an electric driving engine, an internal combustion engine, and a shift transmission having several gears and a multiple clutch. A first transmission element of the shift transmission is coupled in a torque-tight manner to a first rotational part of the multiple clutch and a second transmission element of shift transmission is coupled in a torque-tight manner to a second rotational part of the multiple clutch. A rotor of the electric driving engine is coupled in a torque-tight manner to a third rotational part of the multiple clutch, wherein the internal combustion engine is coupled in a torque-tight manner to a third transmission element of the shift transmission.

A hybrid module for a motor vehicle for coupling an internal combustion engine, comprises a first drive shaft, a first electrical machine and a first coupling device, as well as a second drive shaft and, associated therewith, a second electrical machine, and a second coupling device; and further comprises an output element, the first or second drive shaft being connectable to the output element by way of a first or second coupling device, wherein the two coupling devices can be simultaneously actuated by a movement of an actuation element which is mechanically coupled to the two coupling devices. The hybrid module disclosed provides a drive device for a motor vehicle that offers energy-efficient operation in a plurality of different operating modes while requiring a small installation space.

Hybrid module and drive assembly for a motor vehicle

A drivetrain unit for a motor vehicle comprises a hybrid module, which includes an electric machine having a stator and a rotor, with at least two clutches having clutch parts that are respectively connectable to one another. A rotor carrier is provided, to which the rotor is attached and to which in each case one clutch part of the at least two clutches is connected for conjoint rotation therewith. A transmission device interacts with the hybrid module by a first transmission input shaft and the rotor carrier is mounted on the first transmission input shaft so as to be rotatable relative thereto.

A clutch system includes a friction clutch, a ramp system, a pilot clutch, and an actuation element. The friction clutch is for transmitting torque between a torque-introducing element and a torque discharging element. The friction clutch includes a pressure plate. The system is for axially moving the pressure plate. The ramp system has an input ramp and an output ramp. The output ramp is rotatable relative to the input ramp to change an axial extent of the ramp system. The pilot clutch is for initiating rotation of the input ramp relative to the output ramp in response to a speed differential between the torque-introducing element and the torque-discharging element. The actuation element is arranged radially on the inside relative to the friction clutch and is at least partially covered by the friction clutch when viewed in a radial direction.

Clutch system

A clutch system includes a friction clutch and a ramp system. The friction clutch is a multiplate clutch, for example, for transmitting a torque between a torque-introducing element (i.e., an engine drive shaft) and a torque-discharging element (i.e., a transmission input shaft). The ramp system includes an input ramp, an output ramp, a pilot clutch, an actuation element, and a freewheel. The output ramp is rotatable relative to the input ramp to change an axial extent of the ramp system. The pilot clutch is for initiating rotation of the input ramp relative to the output ramp when there is a differential speed between the torque-introducing element and the torque-discharging element. The actuation element is for actuating the pilot clutch. The freewheel is arranged in a torque path in parallel with the friction clutch, and arranged to transmit a torque flow from the torque-introducing element to the torque-discharging element and interrupt a torque flow from the torque-discharging element to the torque-introducing element.
