Abstract

A vehicle axle for a two-track vehicle may include a transmission which has an axle differential from output sides of which axle shafts are led to vehicle wheels. For axle-differential lubrication, a lubricant is able to be guided into the housing interior space of a differential housing of the axle differential via at least one housing opening of the differential housing. The axle-differential lubrication may be by way of lubricant ejection of an adjacent rotating transmission component. During the axle-differential lubrication, lubricant drops are able to be cast from the transmission component into the housing interior space of the differential housing through the housing opening of the differential housing under the action of centrifugal force.

Dependent claims

A vehicle axle for a two-track vehicle, comprising:

a transmission including,
a differential housing having a housing interior space and at least one housing opening into the differential housing,
an axle differential situated in the housing interior space, and from output sides of the axle differential, axle shafts are led to vehicle wheels, and
an adjacent rotatable transmission component adjacent to the axle shafts, so that axle-differential lubrication by way of lubricant ejection from the adjacent rotatable transmission component, during which lubricant ejection, drops of a lubricant are able to be guided and cast from the adjacent rotatable transmission component into the housing interior space of the differential housing through the at least one housing opening of the differential housing under centrifugal force provided by the adjacent rotatable transmission component.
