Abstract
A transmission system for hybrid propulsion vehicles comprises a torque convertor, an external output shaft of the torque convertor which is rigidly connected to the output of the convertor and an internal output shaft which is rigidly connected to the input of the convertor, a gearbox which can be selectively connected to drive wheels of the vehicle, a main coupling member for selectively transmitting the movement of the external shaft to the gearbox, an electric motor which can be selectively operated as a motor and as an electrical generator. The transmission system further comprises a downstream coupling member and an upstream coupling member which are arranged upstream and downstream of the torque convertor, respectively, and which are capable of selectively connecting the rotor element to the external shaft and the internal shaft, respectively. The electric motor further comprises a rotor element which is arranged at an opposite distal end of the external shaft with respect to the torque convertor, with the main coupling member being arranged in an intermediate position between the torque convertor and the distal end.
