Dust cap assembly and dust cap device for such assembly

摘要

The present invention relates to a dust cap assembly, comprising a semi-trailer (2) and a towing vehicle (3) for closing a kingpin (21), the kingpin being dug into a borehole (22) for automatic five-wheel coupling and (hollowed out) and the kingpin is arranged on the lower side 20 of the semi-trailer 2, which functions as a counter bearing for the five-wheel plate 31 of the towing vehicle 3, and the dust cap device 1 is -Arranged in contact with the lower side (20) of the trailer (2) and so that the dust cap device can rotate around the kingpin (21), the device covering the borehole (22) provided in the kingpin (21) Has a dust cap (11) for, and the dust cap (11) releases the borehole (22) from the basic position where the dust cap covers the borehole (22) at the kingpin (21) during the coupling process. A circular circumferential bearing disk designed to move on the dust cap device 1 in a coupling position and to mount the dust cap device 1 so that the dust cap device can rotate around the kingpin 21 A circular ring-shaped bearing disc 25 with 26 is provided, which is fixed coaxially to the kingpin 21 on the lower side 20 of the semi-trailer 2, and has a circular circumference. The directional bearing seat 26 is, on a circular ring-shaped bearing disk 25, a first sliding bearing edge 261 on the inner circular opening and a second sliding bearing edge on the outer rim on which the dust cap device 1 is engaged. 262). The invention also relates to a dust cap device for such an assembly.
