A transmission assembly may include a transmission housing; and a receiving space for receiving an electrical functional unit. The receiving space may be formed by at least one wall in the transmission housing and a lid unit, the receiving space may be sealable from an exterior environment via a seal in a contact region on the transmission housing and the lid unit. The lid unit may be connectable to the transmission housing by a screw, where the lid unit includes a channel through which at least part of the screw passes, and where the channel has an inner thread section.

A piping () for guiding a fluid within a drive train unit (G) of a motor vehicle includes a pipe (R). A stop (RA) is formed at a first end (R) of the piping (). A sealing element (RD) is provided at a second end (R) of the piping (). The sealing element (RD) acts as an axial seal. In order to improve a sealing effect of the sealing element (RD), the piping () is loaded along an extension direction of the piping (). A drive train unit (G) for a motor vehicle including such a piping () and a method for installing such a piping () into such a drive train unit (G) is also provided.

An arrangement of at least one sensor track-scanning rotor position sensor (A) of an electric machine (EM) in a hybrid transmission housing () that includes a torque converter () and a housing-affixed oil supply plate arrangement is provided. The rotor position sensor (A) is attached on an oil-supply-plate side, and a sensor ring (), as a sensor track, is attached on a converter side. A hybrid transmission housing () including the arrangement is also provided.

A transmission (G) for a motor vehicle includes a housing (GG), a gear set (RS) arranged within the housing (GG), an electric machine (EM), and a power electronics module (LE). The power electronics module (LE) includes a carrier element (S), a DC voltage terminal (DC), an inverter (INV), and an AC voltage terminal (AC). The housing (GG) includes, on an outer wall (GGA), a region (GGE) for accommodating the power electronics module (LE), which is closable with the carrier element (S) of the power electronics module (LE). The region (GGE) of the housing (GG) and an inner side (SI) of the carrier element (S) form a dry space (TR) for accommodating the inverter (INV), which is attached to the carrier element (S). The region (GGE) of the housing (GG) at least partially separates the gear set (RS) from the dry space (TR).

Transmission for a motor vehicle

A connection device may include a releasable electrical connection between a first current conducting element of a power electronics system and a second current conducting element of a transmission. The connection device may be configured such that it is removably locatable in a first opening in at least one of a power electronics housing and a second opening in a transmission housing. A transmission for a motor vehicle may include the connection device.

Connection device

An automatic transmission of a motor vehicle driven by an internal combustion engine with a transmission oil circuit, a main oil pump, mechanically driven by a combustion engine, and an auxiliary oil pump () that can be electrically driven and is located inside an oil sump (). It is proposed that the auxiliary oil pump () is arranged transversely with respect to the travel direction (x) of the motor vehicle.

Automatic transmission for a motor vehicle

A drivetrain is proposed for a hybrid motor vehicle, which comprises an electric machine arranged between the vehicle's transmission () and a differential () of a driven axle in order to drive the axle via a Cardan shaft () or another shaft capable of torque transfer in which a transmission () made as a reducing gear system is arranged in the force flow direction behind the electric machine in order to produce the necessary speeds and torques and transfer them to the Cardan shaft or to the other shaft.

Drivetrain of a hybrid motor vehicle

The invention proposes a hybrid drive for a vehicle with a power train, which has a first electric machine (), which is permanently connected to an input shaft () of the vehicle transmission () arranged between an internal combustion engine () and a vehicle transmission () with changeable gear ratio, and which can be operated as an engine or as a generator, and a hydraulic pump () for the vehicle transmission (), in which at least one first shiftable clutch device () is arranged between the internal combustion engine () and the vehicle transmission (), and in which the hydraulic pump () is torque-proof connected to the input shaft () of the vehicle transmission (). A hybrid drive is also proposed, which comprises two electric machines, in which the hydraulic pump () is coupled via at least one element for force transfer to the input shaft () of the vehicle transmission ().

Hybrid drive for a vehicle

A parking lock of an automatic transmission avoiding an undesirable engagement of a lock member () in a parking lock gear, during occurring extreme accelerations in normal driving of a motor vehicle. An arrester () is provided which, in the driving gear stages of the transmission, retains the lock member () with an arresting shape fit.
