1. A differential gear for transmitting a torque to an axle of a motor vehicle, comprising:
a differential basket;
a bevel gear having inner and outer circumferential surfaces, the bevel gear being supported by a contact surface of the differential basket at least with respect to a radial direction;
first and second output shafts having a common rotary axis, the first output shaft extending along the rotary axis and forming a positive connection with the bevel gear at least with respect to a circumferential direction via an outer circumferential surface of the first output shaft and the inner circumferential surface of the bevel gear; and
a multi-plate clutch for selectively connecting the first output shaft with the differential basket, the multi-plate clutch including an inner plate carried by a section of the outer circumferential surface of the bevel gear and an outer plate carried by the differential basket, wherein the contact surface is arranged along the rotary axis between a plurality of bevel teeth of the bevel gear and the section of the outer circumferential surface of the bevel gear, and wherein the bevel gear is supported by the contact surface via a support element, and the plates are supported by the differential basket via the support element with respect to an axial direction extending along the rotary axis.
