Abstract:
1. A device for reversing the direction of an automotive wheeled vehicle, positionable between a drive shaft and wheels of said vehicle, comprising: at least one input shaft connectable by a disengageable device for transmission of movement to the drive shaft of said vehicle to be driven in rotation in one and the same direction; a forward/reverse output shaft; a reversible mechanism comprising a clutch sleeve that is carried by one of said input and output shafts, the clutch sleeve comprising at least one blocking system that comprises at least one blocking element that is carried by the input shaft and that is drivable in rotation by said input shaft, said at least one blocking element mounted to move between at least two positions including an off position in which the movable clutch sleeve is permitted to operably switch between two or more operating positions, and an on position, in which said blocking element directly or indirectly prevents said movable clutch sleeve from operably switching between said two or more operating positions, wherein said at least one blocking element is sensitive to a speed of rotation of the input shaft and switches automatically from the off position to the on position when the input shaft is driven at a speed of rotation that exceeds a predetermined threshold value.
