A differential comprising at least one drive wheel, at least two axle wheels, at least one compensating wheel and at least one connecting element, wherein the connecting element experiences at least a first torque at least from the drive wheel, and wherein the connecting element transmits at least a second torque to at least one of the at least two axle wheels. The drive wheel is constructed such that the drive wheel at least partially surrounds at least one inner chamber; the connecting element is arranged at least partially inside the inner chamber that is at least partially surrounded by the drive wheel, and the connecting element is constructed in one piece.

Differential

A fastening device comprising at least one nut, at least one support unit, and at least one spring element, with the nut, the support unit, and the spring element being constructed and matched to each other in such a way that the spring element exerts a force between the nut and the support unit.

Fastening device

A screw connection having a screw section and a nut threaded thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received on the nut so as to be rotatable relative to the nut. The intermediate disk includes a grid distributed around the circumference of the intermediate disk, and the nut carries at least one resiliently elastic, radially displaceable catch formed by a sheet-metal part which, after installing the nut, positively engages the grid to lock the nut against rotation relative to the screw section and intermediate disk. Upon application of a wrench to the nut, the at least one resilient, radially displaceable catch is compressed and drawn out of engagement with the grid, so that the nut can be rotated relative to the screw section.
