AI Technical Summary
Technical Problem
Existing hybrid transmission systems have a large axial length, which limits their usability and results in significant traction losses.
Method used
The clutches and blocking devices, located outside the wet space, overlap axially and are cleverly staggered to reduce the length of the hybrid transmission.
Benefits of technology
The design with a short axial profile reduces the length of the hybrid transmission, decreases traction loss, and achieves a more compact structure.

Abstract
The invention relates to a hybrid transmission (1) for a motor vehicle drive train (40), having a housing (3) forming a wet space (2), an electric machine (4), a transmission device (6) which is arranged at least in part in the wet space (2) and is coupled to a rotor (5) of the electric machine (4), a clutch (9) which is arranged outside the wet space (2), and a blocking device (10) which is likewise arranged outside the wet space (2) and engages with a component of the clutch (9) or of the transmission device (6), wherein the blocking device (10) and the clutch (9) at least partially overlap in the axial direction. Furthermore, the invention relates to a drive train (40) having the hybrid transmission (1).
