DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] FIG. 1 shows a king pin arrangement 1 which has a king pin 10 and a mounting element 20 in the form of a receiving plate. The king pin 10 of the king pin arrangement 1 has a king pin head 14, which is formed as a freely extending end of the king pin 10. The base section 12 of the king pin 10 is frictionally, positively and materially secured to the mounting element 20. The mounting element 20 has a first measuring surface 30, which is formed entirely by the end face of the measuring projection 32. The first measuring surface 30 has a continuous height profile in the direction of the king pin R10, with the measuring projection 32 extending from a base surface 22 of the mounting element 20.

[0032] FIG. 2 shows a mounting element 20 which could in principle also be used in the king arrangement 1 shown in FIG. 1. The mounting element 20 has a measuring projection 32 whose end faces are formed by the first measuring surface 30 and the second measuring surface 40. Between the first measuring surface 30 and the directly adjacent second measuring surface 40 there is a shoulder which separates the first measuring surface 30 from the second measuring surface 40.

[0033] FIG. 3 shows a side view of a king pin arrangement 1. The king pin arrangement 1 also has a king pin 10 and a mounting element 20. In FIG. 3, the mounting element 20 is designed as a receiving plate. FIG. 3 shows the height difference h of the first measuring surface 30. The first measuring surface 30 forms an end face of the first measuring projection 32. The king pin 10 extends from its base section 12 in positive king pin direction R10. The distal end in the positive king pin direction R10 is formed by the king pin head 14 of the king pin 10.

[0034] FIG. 4 shows an assembly element 20 which has two measuring projections 32. One measuring projection 32 has the first measuring surface 30 and the second measuring projection 32 has the second measuring surface 40. The measuring projections 32 are formed in such a way that the end faces of these measuring projections 32 are all formed by the first measuring surface 30 or by the second measuring surface 40.

[0035] FIG. 5 shows another view of a king pin arrangement 1. FIG. 5 shows that the first measuring surface 30 extends in an angular range W1 around the king pin direction R10 in the circumferential direction U. In FIG. 5, the angular range W1 around the king pin direction R10 extends 180 in the circumferential direction. The circumferential direction U, the radial direction R and the king pin direction R10 form a cylinder coordinate system, as can be seen in FIG. 5.
