- 1. A drive assembly for a four wheel vehicle, comprising:
- a front axle with wheels which are driven permanently; a rear axle with wheels which are driven by a viscous coupling arranged in a longitudinal driveline; a freewheeling unit connected along the driveline in series with a viscous coupling so that during forward driving the freewheeling unit allows the rear wheels to rotate faster than the front wheels; a second viscous coupling connected along the driveline in parallel with the freewheeling unit, said second viscous coupling having a torque transmitting capacity no greater than that of the first viscous coupling; and a housing, the first and second viscous couplings, together with the freewheeling unit, being accommodated in the housing.
