DETAILED DESCRIPTION OF THE DRAWINGS

[0021] The invention is described below with reference to FIGS. 1 and 2 which show an exemplary embodiment, wherein the same reference signs refer to the same structural and/or functional features.

[0022] FIG. 1 shows a side view of a height detection system of a motorcycle for determining a load-dependent height of a rear carrier part 1 relative to a rear wheel swing arm 2 of the motorcycle. FIG. 1 shows a measuring device 3 which connects the rear carrier part 1 and the rear wheel swing arm 2. Furthermore, a fastening web 4 is formed integrally on the rear carrier part 1. The fastening web 4 protrudes from the rear carrier part 1 in the direction of the rear wheel swing arm 2, and is formed flat in the manner of a fin. This forms a lateral bearing face 5 for the measuring device 3. The lateral bearing face 5 lies in the plane of the longitudinal extent and vertical extent of the rear carrier part 1. The outer contour of the fastening web 4 in this plane rectilinearly extends a front outer edge of the base profile 7 of the rear carrier part 1. Furthermore, in this plane the fastening web 4 forms a rounded end in the direction of the rear wheel swing arm 2, and then runs in an S-shape back to the base profile 7 of the rear carrier part 1. Four stiffening ribs 6 extend from the base profile 7 of the rear carrier part 1 along the lateral bearing face 5. A first stiffening rib 6 transforms from the base profile 7 of the rear carrier part 1 into the outer contour 8 of the fastening web 4, and in this region forms a reinforced outer contour 8 which runs up to the rounded end in the direction of the rear wheel swing arm 2. Furthermore, three stiffening ribs 6 extend spaced apart from each other over the lateral bearing face 5. The stiffening ribs 6 have a different angular orientation relative to a perpendicular of the vertical extent of the rear carrier part 1. The angle between the stiffening ribs 6 and the perpendicular vertical extent of the rear carrier part 1 becomes more acute from the first stiffening rib 6 to the adjacent stiffening ribs 6. Three steps 9 are formed in the region of the lateral bearing face 5, and the profile thickness tapers from the base profile 7 of the rear carrier part 1 in the direction of the rear wheel swing arm 2. The stiffening ribs 6 here extend only over the step 9 with the greatest profile thickness. In the region of the smallest profile thickness, the adjacent step 9 has an arcuate form which is adapted to the geometry of the measuring device 3.

[0023] The measuring device 3 in FIG. 1 comprises a pushrod 10, a deflector lever 11 and a potentiometer 12. The deflector lever 11 is arranged centrally on the step 9 with the smallest profile thickness, between two fixing bores for the potentiometer 12. The arcuate step 9 here runs adjacent to and along the rounded deflector lever 11. The pushrod 10 and the deflector lever 11 connect the rear wheel swing arm 2 to the fastening web 4. The potentiometer 12 for measuring the height is arranged at the fastening web 6 so as to register the deflection of the deflector lever 11.

[0024] FIG. 2 shows a rear view of the height detection system from FIG. 1 which is arranged as described above and attached to the fastening web 4.
