Title: DIFFERENTIAL GEARING FOR A MOTOR VEHICLE
Abstract:
The invention relates to a differential gearing (10) for a motor vehicle, having a ring gear (22) which has an external toothing system (24) and can be driven by a pinion (18) of the motor vehicle, and having a differential unit (26) which can be driven by the ring gear (22) for rotational speed compensation between wheels (14, 16) of the motor vehicle which can be driven by a pinion (18) via the differential unit (26), wherein the differential unit (26) has an internal gear (30) which can be driven by the ring gear (22), has an internal toothing system (28), and via which the wheels (14, 16) can be driven, wherein, in relation to a torque flow from the ring gear (22) to the internal gear (30), a coupling device (32) is arranged between the ring gear (22) and the internal gear (30), which coupling device (32) can be adjusted between at least one coupled position (K), in which the internal gear (30) is coupled to the ring gear (22), and at least one decoupled position (E), in which the internal gear (30) is decoupled from the ring gear (22).
