ABSTRACT:
A method and device for controlling the fork of a synchromesh for a gear box. A command signal sent by the operator is converted into signals by a modulator whose output controls an electric valve to open and close several times in succession. The electric valve controls a jack which in turn controls the fork connected to a sliding gear associated with the synchromesh, whereby the instantaneous pressure of the fluid supplied to the jack is varied during the steps of approach, synchronization, and locking of the synchromesh.
