A vehicle transmission includes a transmission housing defining an oil sump space and a hybrid space, with the hybrid space being arranged vertically above the oil sump space. The transmission further includes a first oil guide shell and a second oil guide shell each fixed to the transmission housing. Additionally, the transmission includes rotating components installable in a portion of the hybrid space between the first oil guide shell and the second oil guide shell in an axial direction, where the rotating components includes at least one electric machine, a damper, and a torsional shock absorber. Two contactless gap seals are formed by one of the oil guide shells and at least one of the rotating components such that oil entry from the oil sump into the portion of the hybrid space is delimited axially by the oil guide shells and radially by the gap seals.

Vehicle transmission

An automatic transmission (1) includes a transmission housing, a hydrodynamic torque converter (5), a first brake, a second brake, an intermediate plate (6) fixedly connected to the transmission housing and with ducts for supplying the hydrodynamic torque converter (5) and the two brakes (A, B) with oil. An oil guide shell (7) is arranged between the hydrodynamic torque converter (5) and the intermediate plate (6). Oil coming from the two brakes sinks via oil ducts (39.1, 39.2, 39.3) in the transmission housing and the intermediate plate (6) via the inflow opening (40) in the oil guide shell (7). The hydrodynamic torque converter (5), via rotation, conveys the oil to the elevated oil ejection opening in the oil guide shell (7), from where the oil sinks into the tank (8) via a gap (52) delimited by the oil guide shell (7) and the intermediate plate (6).

A lubricant guide shell () for includes a first, radially extending section (), which is provided for being situated axially opposite an end face () of a torque converter () in an installed state of the lubricant guide shell (). The first section () transitions radially outwardly into a second, axially extending section (), which, in the installed state of the lubricant guide shell (), is configured for axially at least partially and radially outwardly encompassing the torque converter starting from the first section (). The first section () as well as the second section () are configured to be completely circumferential.

A wet-running multi-disk clutch (B) for a motor vehicle transmission (G) includes a piston (K) provided at a first side of the multi-disk clutch (B), by which a force acting in an axial direction is applicable onto inner and outer clutch disks (IL, AL) in order to engage the multi-disk clutch (B). The multi-disk clutch (B) is supported against an abutting surface (AF) via an end disk (ALE) of the outer clutch disks (AL) at a second side, which is opposite the first side. Grooves (N) are provided at one or both of the abutting surface (AF) and the end disk (ALE). The grooves (N) are configured and arranged such that cooling fluid (O) routed to the multi-disk clutch (B) is flowable out of the multi-disk clutch (B) through the grooves (N).

A hybrid drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS) and a second section (LS) and is arranged in such that the first section (LS) partially encompasses a second face end (TC) of the torque converter housing (TCG) and the second section (LS) partially encompasses a circumferential surface of the torque converter housing (TCG).
