Claim 0:
1. A two-speed torque transmission device for a vehicle comprising at least one electric motor, the torque transmission device comprising:
a first clutch comprising a first input element capable of being driven by the electric motor, and a first output element, torque being transmitted between the first input element and the first output element when the first clutch is closed,
a second clutch comprising a second input element capable of being driven by the electric motor, and a second output element, torque being transmitted between the second input element and the second output element when the second clutch is closed,
a transmission member,
a first transmission mechanism arranged to transmit torque between the first output element and the transmission member, according to a first gear ratio, the first gear ratio being the slowest gear ratio of the torque transmission device,
a second transmission mechanism arranged to transmit torque between the second output element and the transmission member, according to a second gear ratio different from the first gear ratio, the second gear ratio being the fastest gear ratio of the torque transmission device,
a connection element arranged to permit or interrupt mutual rotational drive between the first output element of the first clutch and the transmission member, by the first transmission mechanism,
wherein the connection element is arranged to interact solely with the first transmission mechanism associated with the first gear ratio.
