Abstract

Differentials having plate packs for exerting a braking torque onto the output shafts of the gear unit are known. The brake device is intended to be designed such that effective braking can be achieved using it and that it is easy to service. To this end, the invention makes provision for the brake device to be a drum brake having a passive element, exhibiting a cylindrical frictional surface, and brake shoes, the frictional surfaces of which brake shoes can be placed against the cylindrical frictional surface of the passive element. The passive element can be a brake drum or a radial brake disk, the cylindrical edge of which serves as a frictional surface. The passive element is fastened to the differential cage and/or one of the shafts. The brake shoes are held in a pivotable manner on a carrier plate fastened to the outside of the differential housing.
