A differential assembly with two jointly actuated adjusting means axially

摘要

The invention relates to a differential arrangement 2 for variable torque distribution in the drive train of a motor vehicle, comprisinga differential gear 21 with a rotationally drivable differential cage 4 and two on an axis of rotation a is supported on the side of the output shafts 3, 3 ''which, at the differential cage 4 via a differential gear wheels set 7, 9, 9'' are drivingly connected, wherein between the differential cage 4 and each of the output shafts 3, 3 ''is formed a first drive train;the output shaft 3, 3 ''of a gear stage 14, 14'' which, at the differential cage 4, on the one hand, and one of the output shafts 3, 3 '', on the other hand, and is drivingly connected to the first drive train which is part of a functionally parallel second drive train is;the gear stage 14, 14 '', a friction clutch 15, 15'' to the to - and uncoupling of the second drive train;the friction clutch 15, 15 ''an axially adjusting device 16, 16'' in the form of a ball ramp arrangement for the actuation of the friction clutch, with in each case two to the axis of rotation a coaxial disks 42, 43; 42 '', 43'' which, on their mutually facing end faces of a plurality of low variable ball grooves 44, 45; 44 '', 45'', are held in which balls 41; as well asa single electric motor 52 which, by means of the rotationally drivable disks 43, 43 ''of the two axially adjusting devices 16, 16'' is drivingly connected.
