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

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 vane pump () for an automatic transmission includes a suction-side behind-vane pressure duct () and a pressure-side behind-vane pressure duct (). The suction-side behind-vane pressure duct () is connected to the pressure side () of the vane pump (). A valve device () is connected to the pressure-side behind-vane pressure duct (). During operation of the vane pump (), a pressure-side behind-vane pressure (p DH) can be set in the pressure-side behind-vane pressure duct () with the valve device ().

Vane pump

An oil pump drive device () may include a housing (G), an oil pump drive shaft (AN), an electric motor, and a planetary gear set (RS). The planetary gear set (RS) may be supported by the housing (G) and have a first element (E) connected to a rotor (R) of the electric motor, a second element (E) connected to the oil pump drive shaft (AN), and a third element (E) drivable by a drive source located outside the oil pump drive device (). A first bearing (L) may be supported on the housing (G) and may support at least one of the elements (E, E, E) of the planetary gear set (RS) in a radial direction. The stator (S) of the electric motor is at least partially surrounded by a plastic mass (K), where the stator (S) is attached to the housing (G) via the plastic mass (K).

Oil pump drive device

A vane cell pump for a transmission of a motor vehicle includes a housing. A rotor defines a plurality of slots. The plurality of slots runs radially. A plurality of vanes is arranged in the plurality of slots of the rotor. An end plate is positioned in a bottom area of the housing. The end plate is configured as a fluid guide with a suction channel and a pressure channel. The end plate forms a bottom wall of the housing.
