Description

BRIEF DESCRIPTION OF THE FIGURES

[0023] The invention is explained in more detail hereinafter on the basis of the figures. The features shown in the figures and/or explained hereinafter can be general features of the invention, also independently of specific combinations of features, and can refine the invention accordingly.

[0024] FIG. 1 shows an attachment point equipped according to the invention with a bearing bracket for fastening an axle support on a vehicle body.

[0025] FIG. 2 shows the same attachment point having a spacer part.

DETAILED DESCRIPTION

[0026] The support end 110 of an axle support (auxiliary frame) 100 shown in FIG. 1 is screwed onto a vehicle body 200 at the attachment point 10 by means of two through screws 121, 122. A bearing bracket 300 for mounting a unit for the axle drive is arranged between the axle support 100 or the support end 110 and the vehicle body 200 and is also screwed on. The two fastening screws 121, 122, which are spaced apart from one another, protrude through a first fastening section 320 of the bearing bracket 300, which is thus quasi-clamped between the support end 110 and the vehicle body 200. The bearing bracket 300 is additionally screwed onto the vehicle body 200 at a second fastening section 340. This additional screw connection 123 is also used as an auxiliary screw connection during the installation.

[0027] The bearing bracket 300 is formed as an angled part and has a first leg 310 on which the first fastening section 320 is located and a second section 330 on which the second fastening section 340 is located.

[0028] A bearing element 350 for attaching the unit to be mounted, which is in particular an electric machine or a differential gear, is also located on the second leg 330.

[0029] The attachment variant shown in FIG. 1 is provided for a vehicle axle having axle drive. FIG. 2 shows the same attachment point 10, wherein instead of the bearing bracket 300, a spacer element 400 is arranged between the axle support 100 or the support end 110 and the vehicle body 200 and also screwed on. This attachment variant is provided for a vehicle axle without axle drive.
