<p>The invention relates to a device (10) for hydraulically controlling a gearbox, comprising at least one sliding gear (24) moved by a fork (23). The control device includes: at least one hydraulic actuator (21) which can move the fork (23), at least one electrically controlled valve (13, 17) which can modify the state of the hydraulic actuator (21), and a system (26) for controlling the electrically controlled valve (13, 17). The control device (10) is characterised in that the electrically controlled valve (13, 17) is of the all-or-nothing type and in that the device also includes at least one flow limiter (12, 18) and an accumulator (16), both of which are coupled to the electrically controlled valve.</p> |
