Lock differential group with a coupling package pre-spring arranged between an axle wave wheel and a differential friction cell element

摘要

Differential assembly group with a differential housing, a differential transmission set, a coupling package and a pre-spring. The differential gearbox is mounted in the housing and has an axle wave wheel and one or more differential gearbox elements on which the differential gears are rotated. The coupling package is incorporated in the differential housing and has a large number of first coupling discs, which are axially shiftable but rotary coupled with the differential housing, as well as a large number of second coupling discs, which grip together with the first coupling discs and axially shiftable,but are fixed to the shaft wheel. The pre-tension spring is attached to one or more differential friction cell elements and the axle wave wheel and pulls the axle wave wheel away from one or more differential friction wave elements in order to tighten the coupling package.
