摘要： A drive mechanism for motor vehicles having two drive axles is disclosed. The drive mechanism includes a transmission drive followed by a differential gear unit. The differential gear unit includes first and second driven members. The first driven member is drivingly connected to the first drive axle and, via a spur gear drive system, to a first set of friction plates in a fluid friction clutch unit. The second driven member is drivingly connected to the second drive axle and, also via a spur gear drive system, to a second set of friction plates in a fluid friction clutch unit. The first set of plates and the second set of plates of the clutch unit are frictionally coupled to each other and thus act to equalize the rotational speeds of the two drive axles.To enhance the operation of the drive mechanism, the spur gear drive system connecting the driven members to the clutch unit provides a gear ratio greater than one. In order to make the fluid frictional clutch unit easily replaceable, it is constructed as a modular unit and is located externally of the differential gear unit.
