Abstract: The device (10) is associated to a multidisk clutch (1) for motor vehicles, and allows the automatic disengagement thereof in the deceleration and/or braking initial phase, before that the driver operates the clutch lever (1) for downshifting. The device (10) includes a ramped plate (11) connected to the transmission, which features front cam profiles (110) adapted to actuate oscillating rocker arms (13), arranged inside a drum (5) provided in the clutch (1), when a back torque is generated by the drive wheel of the vehicle, during the deceleration and/or braking step. The rocker arms (13) rotate simultaneously from an inoperative position (N) to an operative position (H), causing the pusher plate (9) to move away with a reduction of the pressure exerted on the sets of friction rings (4, 7), which, therefore, can slip with respect to one another. This avoids abnormal blockages of the rear wheel and improves the drivability and curving of the motor vehicle.

Abstract translation: 装置（10）与用于机动车辆的多叶片离合器（1）相关联，并且在驾驶员操作用于换低档的离合器杆（1）之前，允许其在减速和/或制动初始阶段中自动分离。 装置（10）包括连接到变速器的倾斜板（11），其具有布置在设置在离合器（1）中的滚筒（5）内部的适于致动摆动摇臂（13）的前凸轮轮廓（110） 当在减速和/或制动步骤期间由车辆的驱动轮产生后转矩时。 摇臂（13）从不工作位置（N）同时旋转到操作位置（H），导致推板（9）随着施加在摩擦环组（4,7）上的压力的减小而移开 ），因此，它们可以相对于彼此滑动。 这避免了后轮的异常堵塞，并提高了机动车辆的驾驶性能和弯曲性。
