<p>A device for converting a front-wheel-drive transmission of a motor vehicle with a transverse engine into a permanent four-wheel-drive transmission, comprising a Ferguson-type fluid coupling (14) carried by a hollow shaft (13) coaxial with one of the front half-shafts (11) and fixed for rotation with the housing (7) of the front differential (9). In the event of slippage of the front axle, the Ferguson coupling (14) is arranged to cause rotation of a tubular hub (17) coaxially rotatably mounted on the hollow shaft (13) and carrying a ring gear (25) which, through a transmission unit (26-30, 33), drives a rear differential (34) for transmitting the torque to the half-shafts (35, 36) of the rear wheels of the vehicle.</p> |
