摘要： A gear change device for a motor vehicle has a braking member for stopping a rotation of a primary shaft before engagement of a reverse gear. The braking member includes a lever pivotally mounted on a gearbox about a separate axis with respect to axes of the primary and secondary shafts of the gear change device. The braking lever is controlled by an electrically-driven actuator by a pusher member displaceable by the actuator in a direction substantially tangential with respect to the primary shaft, towards an operative position in which it interposes with a wedge-like action between the braking lever and a fixed abutment wall, so as to press the brake pad against a cooperating part which is connected in rotation with the primary shaft.

摘要： A transmission includes a first primary shaft carrying driving gearwheels for odd gears and reverse, a coaxial second primary shaft carrying driving gearwheels for the even gears, and a secondary shaft carrying idle driven gearwheels meshing with the driving gearwheels. The gearbox has a gear shift device having sliding engagement sleeves each arranged to connect a driven gearwheel corresponding to a given gear for rotation with a secondary shaft. Corresponding sliding shift forks cause an engagement sleeve to slide between a neutral and shift positions. A rotary drum has grooves on its cylindrical surface in which a stud slides, and is connected for translation with a respective shift fork in its sliding direction. An actuation unit rotates the drum stepwise among angular positions corresponding to engagement sleeves' predetermined positions. In a first angular position the engagement sleeves simultaneously engage gear reverse.

摘要： A device for selection and engagement of the gears of a gearbox for motor vehicles has a control shaft mounted rotatable and axially movable with respect to the casing. Mounted on the shaft is a hub having an engagement finger for controlling gear engagement devices, which is configured to oscillate in the space between two fingers of a selection mask, which is mounted on the shaft axially movable therewith and is guided with respect to the casing so as not to follow rotation of the shaft and the hub when a gear is engaged. During displacement of the engagement finger towards an extreme position preliminary to the engagement of the reverse gear, the selection mask is forced to move temporarily into a rotated position, wherein it actuates one or more of the selector devices of the forward gears to enable silent engagement of the reverse gear.
