An endless track or belt disposes on the plurality of idler wheels and the main driver. The engine, transmission, and shock absorbers are each contained within the contour of the endless track.

Abstract: A method for the readjustment of an actuator of an all-wheel drive clutch of a motor vehicle that includes determining a clutch slip value corresponding to a difference between the speed of a primary axle and the speed of a secondary axle; determining a reference secondary axle torque corresponding to the proportion of a driving torque which is transmitted to the secondary axle and for which a clutch slip value of substantially zero is expected; and comparing the clutch slip value with a threshold value and comparing a desired clutch torque with the reference secondary axle torque. A desired clutch torque/control signal relationship for the clutch actuator is changed in dependence on the result of these comparisons.
