Abstract:
1. A transmission for a road vehicle with hybrid propulsion; the transmission comprising: a gearbox with at least one primary shaft, at least one secondary shaft and at least one pump configured to be actuated by an activating shaft; at least one clutch connected to the primary shaft and including a part which is normally transmissive and which is configured to be connected to a drive shaft of a thermal engine; at least one reversible electric machine having a shaft which is mechanically connectable to the primary shaft; a first mechanical transmission to transmit the motion from the normally transmissive part of the clutch to the activating shaft with the first mechanical transmission including a first freewheel to transmit the motion only when it rotates in a first rotation direction; and a second mechanical transmission which is connected mechanically to the shaft of the electric machine, transmits the motion from the shaft of the electric machine to the activating shaft with the first mechanical transmission including a second freewheel to transmit the motion only when it rotates in a second rotation direction which is opposite to the first rotation direction of the first freewheel; wherein the transmission comprises a connecting device which is electrically controllable to mechanically connect the shaft of the electric machine to the primary shaft of the gearbox and which is electronically controllable to connect or disconnect the shaft of the at least one reviersible electric machine and the at least one primary shaft.
