Abstract
The series hybrid traction assembly comprises an electric generator set, a static converter and at least one tandem traction set intended to drive two driving wheels of a vehicle. The traction set (1) comprises two back-gear motors each comprising an electric motor (4, 14) and a reducing gear (7, 17) which drives the wheel by means of a transmission shaft. The two reducing gears are adjacent to a median plane (24). The motor driving the wheel situated on one side of the median plane is on the other side of such plane, so that each driving line preferably has a Z-shaped outline and the axial space requirement of the traction set is reduced. The assembly also comprises a generator set (40) formed of a heat engine (41) and a generator (42), this set being arranged facing one (4) of the electric motors, on the other side of the median plane. A very compact assembly results.
