Abstract

Transmission (1) for a motor vehicle with hybrid propulsion or traction comprising: - a first machine (20) comprising a rotor (22) integral with a main power transmission shaft (21) which is rotationally integral with a main gearbox input shaft (25) configured to be coupled or decoupled from the vehicle's wheels, - a second machine (40) comprising a rotor (42) integral with a secondary power transmission shaft (41) which is rotationally integral with a secondary gearbox input shaft (45) configured to be coupled or decoupled from the vehicle's wheels, and - a heat engine integral with an input shaft (60). The second electric machine (40) is connected to the wheels independently of the heat engine. Figure for the abbreviation: Fig 2
