Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] An exemplary embodiment of the present invention is described below with reference to the accompanying figures.

[0016] FIG. 1 schematically shows a rear axle of a first motor vehicle variant of a motor vehicle series according to aspects of the invention, wherein a stabilizer is fastened to a chassis component fastening device, and

[0017] FIG. 2 schematically shows a rear axle of a second motor vehicle variant of the motor vehicle series according to aspects of the invention, wherein a motor-pump unit assembly according to aspects of the invention is fastened to the chassis component fastening device.

DETAILED DESCRIPTION OF THE INVENTION

[0018] FIG. 1 shows a rear axle 1 of a first motor vehicle variant 100 of a motor vehicle series according to aspects of the invention. The rear axle 1 comprises two wheels 11, which are each connected to a vehicle body 2 of the motor vehicle variant 100 via a wheel suspension 12, which is not specified in more detail.

[0019] A chassis component fastening device 3 is arranged on the rear axle 1 and comprises two fastening elements 31, 32 fixedly connected to the vehicle body 2. The two fastening elements 31, 32 are arranged spaced apart from one another relative to a transverse vehicle direction Q and respectively have two screw-on points 311, 312, 321, 322.

[0020] A stabilizer 4 is fastened to the chassis component fastening device 3, wherein a first stabilizer bearing 41, which mounts the stabilizer 4, is screwed on at the two screw-on points 311, 312 of the first fastening element 31, and a second stabilizer bearing 42, which mounts the stabilizer 4, is screwed on at the second screw-on points 321, 322 of the second fastening element 32, in each case by means of screws extending substantially parallel to the transverse vehicle direction Q.

[0021] FIG. 2 shows the rear axle 1 of a second motor vehicle variant 200 of the motor vehicle series according to aspects of the invention. The second motor vehicle variant 200 comprises an active hydraulic damping system (not shown here) and therefore differs from the first motor vehicle variant 100 in particular in the configuration of the wheel suspensions 12. However, the second motor vehicle variant 200 comprises the same, i.e., an identically designed, chassis component fastening device 3 as the first motor vehicle variant 100, to which chassis component fastening device a motor-pump unit assembly 10 according to aspects of the invention is, however, fastened in the second motor vehicle variant 200.

[0022] The motor-pump unit assembly 10 comprises a motor-pump unit 101 of the active hydraulic damping system and a holding tube 102. The holding tube 102 extends parallel to the transverse vehicle direction Q and enters a tube receptacle 1012 formed on a pump cover 1011 of the motor-pump unit 101. The holding tube 102 is fastened to the motor-pump unit 101 via a brush device 1013 arranged in the tube receptacle 1012.

[0023] A first holding element 103 is arranged at an end of the holding tube 102 facing away from the motor-pump unit 101 and is fixedly connected to the holding tube 102. The first holding element 103 is screwed on at the screw-on points 311, 312 of the first fastening element 31 of the chassis component fastening device 3 by means of screws extending substantially parallel to a holding tube longitudinal direction L of the holding tube 102, i.e., parallel to the transverse vehicle direction Q.

[0024] A second holding element 104 is arranged on a side of the motor-pump unit 101 facing away from the first holding element 103 and is fixedly connected to the motor-pump unit 101. The second holding element 104 is screwed on at the screw-on points 321, 322 of the second fastening element 32 of the chassis component fastening device 3 by means of screws extending substantially parallel to the holding tube longitudinal direction L.

[0025] According to aspects of the invention, in the motor-pump unit assembly 10, a distance between the motor-pump unit 101 and the first holding element 103 is adaptable, for example by providing holding tubes 102 of different lengths.
