Abstract
The utility model relates to an automobile component, in particular to a flange structure of a rim for larger vehicles, comprising a barrel and a retainer ring positioned at the end part of the barrel, wherein the retainer ring is limited by a race, and the race is limited by a locking ring buckled at the end part of the barrel. The hole wall of the inner hole of the retainer ring is provided with a segment of inner circular conical surface, and meanwhile the outer wall of the race is provided with a segment of outer circular conical surface. The retainer ring and the race are limited by the match of the inner circular conical surface and the outer circular conical surface. The flange structure of the rim changes the structure in the traditional structure that the retainer ring and the race are limited by the end surface and adopts the structure of the match of the inner conical surface and the outer conical surface for limiting, and the contact area and the friction between the retainer ring and the race are increased, so the retainer ring and the race can avoid sliding wear by self locking in the operation process, and therefore the service life of the rim is prolonged.
Description
Technical field
The utility model relates to a kind of automobile component, specifically is a kind of rim construction that is used for the wheel rim of relatively large vehicle.
Background technology
Existing large-scale wheel rim generally includes and is used for cooperating with wheel shaft and the cylindrical shell of supporting tire, is used in rim section tire being carried out the parts such as back-up ring of axial limiting.Back-up ring is carried out spacing usually to its external side end by a seat ring, seat ring is then undertaken spacing by a retainer that is stuck in the cylindrical shell end.In this structure, back-up ring mainly contacts spacing with the jut of back-up ring by outside end face, and back-up ring and seat ring guarantee that by friction force it does not relatively rotate under the pressure of tire.Because the area of contact of back-up ring and seat ring is less, friction force is also less, and in the vehicle operating process, back-up ring and seat ring skid easily and make component wear, have reduced the service life of wheel rim.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of globality, back-up ring and seat ring that can improve in the wheel rim use be difficult for skidding wearing and tearing, can improve the rim construction of the wheel rim in wheel rim service life.
The rim construction of wheel rim of the present utility model includes cylindrical shell and is positioned at the back-up ring of cylindrical shell end, and back-up ring is spacing to it by a seat ring, and seat ring is then undertaken spacing by a retainer that is stuck in the cylindrical shell end; The hole wall of the endoporus of described back-up ring has one section internal conical surface, simultaneously has one section outer conical surface on the outer wall of seat ring, and is spacing with cooperating of outer conical surface by internal conical surface between back-up ring and the seat ring.
The utility model has changed the conventional confguration guide ring and seat ring carries out spacing structure by end face, and adopt the structure of inside and outside cone match to carry out spacing, increased area of contact and friction force between the two, make back-up ring and seat ring reliable self-locking and the wearing and tearing of avoiding skidding in operational process, thus the service life of having improved wheel rim.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the rim construction of this wheel rim includes cylindrical shell 1 and is positioned at the back-up ring 2 of cylindrical shell end, and back-up ring is spacing to it by a seat ring 3, and seat ring is then undertaken spacing by a retainer 4 that is stuck in the cylindrical shell end; The hole wall of the endoporus of back-up ring 2 has one section internal conical surface 21, simultaneously has one section outer conical surface 31 on the outer wall of seat ring 3, and is spacing with cooperating of outer conical surface by internal conical surface between back-up ring and the seat ring.
Claims (1)
