Abstract
An arrangement for a four wheel drive motor vehicle which increases the rotational moment transfer from the front axle to the rear axle in the case of a large rotational speed differential between the two axles. The arrangement includes a lamella or plate clutch arranged between the front axle and the rear axle. The front axle is directly driven by the gear change transmission and the rear axle is indirectly driven by the front axle. A one way clutch and a reducing transmission are interposed with respect to the plate clutch in such a way that the characteristic curve for rotational moment transfer versus axle rotational speed differential exhibits a flat slope during normal driving conditions (relatively small speed differentials) and an increasingly steep slope during hazardous driving conditions (relatively large speed differentials).
