Hybrid vehicle twin clutch transmission assembly with rotating electrical machine, in which crankshaft extension and gear shaft are in a supporting and centering relationship relative to each other

摘要

The crankshaft (10) has an extension (35) whose end and that of the main gear shaft (11) are in a supporting and centering (38,48) role relative to each other The transmission assembly includes two clutches (20,60) and an electrical machine (80) fitted between the engine and its gearbox. Each of the clutches has a clutch mechanism (21,61) associated with a friction disk (22,65) and the electric machine. The clutch mechanisms are integral with the machines rotor (81). The friction disk (22) of the first clutch mechanism (21) is integral in rotation with the engine crankshaft (10). The friction disk (65) of the second clutch mechanism (61) rotates with the main gear shaft (11).
