IPC: F16D35/00
Filed: 1986-03-03
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.
