A drive system for a motor vehicle comprises a drive unit with a drive shaft and a torque-transmitting assembly, which is to be connected on the drive side to the drive shaft for rotation in common around an axis of rotation (A) and which is to be connected on the takeoff side to a gearbox. The drive-side connection is accomplished by means of an axial plug-in connection arrangement, and the torque-transmitting assembly is supported in at least one axial direction on the gearbox.

Drive system for a motor vehicle

A device () is described for controlling and/or regulating a hydraulically activatable shifting element. The shifting element () is configured with a piston-cylinder unit () that can be acted upon by a hydraulic operating pressure (p) and can be arranged in an installation space that is connected to an oil sump of the gearing mechanism device. In addition, the device () is provided with an electric motor () that can be actuated by a control and/or regulator unit (), and which is provided with a drive-transformer device () that has a functional connection to the electric motor (), by way of which the rotational drive of the electric motor () can be transformed into the hydraulic operating pressure (p) for the shifting element ().

Device for controlling and/or regulating a hydraulically activatable shifting element of a gearing mechanism and a gearing mechanism

A transmission device () for a vehicle with an electric machine () that is arranged in a housing () is described. The electric machine () can be placed in active connection with a rotating component () that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine () can be transmitted to the component (). At least one electric component (Y) that comprises power electronics for the electric machine () is arranged in a cross-sectional area inside the housing () that is perpendicular to the longitudinal axis of the electric machine () and is located directly adjacent to the electric machine ().

Transmission device for a vehicle

A transmission device () of a vehicle for distributing a driving torque of a transmission input shaft () to at least two transverse vehicle shafts (X;Y;Z;). Between the transmission input shaft () and a transmission output shaft () gear elements (to) are disposed in a housing () for the purpose of implementing different gear ratios. One of the vehicle axles (X;Y;Z) extends through an inner space () of the housing (). In a cross-sectional area disposed perpendicular to the longitudinal axis of the transmission device (), in which area the transverse vehicle shaft (X;Y;Z) that is guided through the housing () is disposed, at least part of an electrical device (), which is mounted to the housing side, and/or at least part of a temperature control unit (), which is mounted to the housing side, are provided.

Transmission device of a vehicle

The transmission unit, especially designed for a motor vehicle, possesses a housing with an input drive shaft with at least one output drive shaft and with an arrangement for the variation of the gear ratio whereby, within the housing a starting element is provided, which is connected to a stepless transmission which, in turn, is in connection with power split apparatus that possesses a first output drive shaft for the rear axle drive and a second output drive shaft, which is connected with a differential for a front axle drive.
