摘要
The present invention relates to a coupling device between a longitudinal transmission shaft (2) and the rear axle (1) of a motor vehicle with four driving wheels, the device permitting the uncoupling of the transmission shaft (2) and the rear axle (1), characterized in that it comprises an epicyclic gear train (3) comprising a casing (11) integral with the chassis of the vehicle, inside which there are: - a planet pinion (5) connected in rotation to the longitudinal shaft (2); - a door - satellite (6) carrying a satellite (7) and integral with a bevel pinion (8) which meshes with a conical ring (9) of the rear axle (1); - a crown (4) connected in rotation to the casing (11) by means of a disengageable coupling device (12, 13, 14).
