Claim 0:
1. A module for a system for driving and synchronizing a countershaft of a transmission gearbox, said module comprising:
a bearing part intended to be mounted without an ability to rotate on a chassis of a vehicle;
a coupling device able to rotate with respect to the bearing part comprising an input element intended to be rotationally coupled to a reversible electric machine and an output element intended to be rotationally coupled to the countershaft, the coupling device having a coupled state in which a clutch device is able to transmit torque between the input element and the output element and an uncoupled state in which the input element and the output element are uncoupled; and
a lock-up device which has a lock-up state in which said lock-up device blocks the rotation of the input element of the clutch device with respect to the bearing part, and a released state in which said lock-up device allows the input element to rotate with respect to the bearing part.
