摘要

The stub axle (17) for the trailer wheel has a bush (1) into which the vertical or near vertical hollow bolt (2) fits. A low-friction sleeve (8) is interposed between the outside diameter of the bolt and the inside diameter of the bush. There is an axial bearing (16), a spring (5) and a retaining nut (6) at the bottom. The top of the sleeve has a thrust bearing (4) with a lower profile (4b) on the upper edge of the bush and an upper profile (4a) on the lower edge of a sleeve (13) on the curved (20) end of a fixed or sprung shaft (20). The bolt has a retaining flange (15) at the top.
