Patent ID: 8322503

Claim:
Transmission element for a traction chain of the parallel hybrid type, said element comprising: a movement input shaft intended to be connected to a thermal engine, a movement output shaft intended to be connected to a gear box, an electrical machine comprising a stator and a rotor, wherein the rotor is rotatably supported in the transmission element, an intermediate member which is rotatably supported in the transmission element independently from the rotor, and which is linked in rotation to the rotor, a first connecting clutch between the input shaft and the intermediate member, and a second connecting clutch between the intermediate member and the output shaft, and a casing comprising (i) a first half-shell supporting the input shaft movable in rotation, and (ii) a second half-shell supporting the output shaft movable in rotation, these two half-shells defining a housing in which are mounted, in a coaxial manner, the two clutches and the electrical machine, wherein the intermediate member and the rotor are engaged mutually through complementary axial teeth which are formed on the intermediate member and on the rotor, respectively.
