Abstract

An epicycloidal train (7a) comprises a planetary wheel (9a) connected to the input shaft (2a) and a satellite carrier (13a) prevented from rotating in the reverse direction by an idler wheel (16a). A crown (8a) is connected to the output shaft (2ab). The crown (8a) and the satellite carrier (13a) may be coupled by means of a clutch (18a) actuated for engagement by means of fly-weights (29) in order to achieve a direct drive. When the clutch is disengaged by an axial thrust (Pac) due to the helical teeth, said thrust action being contrary to that of the fly-weights, the satellite carriers (13a) is stopped by the idler wheel (16a) and the device operates as a reduction unit. The idler wheel (16a) is connected to the rotor (37) of a brake (38) and is stopped with respect to the casing (4) only when the rotor (37) is stopped by the brake. In the neutral position, the brake is released. To set the vehicle in motion, the brake is progressively activated. The rotor is used at the same time as an inertia wheel to stabilize the operation of the engine in the idling mode. Utilization to simplify the conventional inertia wheel and clutch assemblies, to reduce sizes and weights, as well as the inertia moments when the vehicle is running.
