Abstract

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.
