Abstract

The utility model discloses a drop-preventing rim device which comprises a reinforcing ring, an internal half-rim, an external half-rim, a fixing ring, a lock ring and a hexagon bolt, wherein the back surface of the internal half-rim is welded with the back surface of the external half-rim, the reinforcing ring is welded on the front side of the internal half-rim, the fixing ring is welded on the front side of the external half-rim, the lock ring is pressed on the fixing ring, and the lock ring and the fixing ring are fixed through the hexagon bolt. The drop-preventing rim device adopts a novel drop-preventing rim, and thus the safety of a tyre when a vehicle crosses countries is improved, and particularly lower pressure of the tyre is required in desert, gobi and the like, the rim has a remarkable drop-preventing performance.

Description

Anticreep wheel rim device

Technical field

The utility model relates to the auto parts and components fields, particularly relates to a kind of anticreep wheel rim device.

Background technology

Rugged environment has very large challenge to the performance of automobile, when especially requiring tire pressure low in desert, Gobi desert etc., to the performance of motor tire, higher requirement will be arranged.How strengthening the performance of tire, prevent its et out of order under abominable road conditions, is the technical matters that needs to be resolved hurrily at present with the anticreep performance that strengthens tire.

The utility model content

Main purpose of the present utility model solves the deficiencies in the prior art exactly, and a kind of anticreep wheel rim device is provided, and adopts novel anticreep wheel rim, and when the raising automobile is cross-country, the safety of tire, make it have superior anticreep performance.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of anticreep wheel rim device is provided, comprise: ring stiffener, interior half wheel rim, outer half wheel rim, set collar, lock ring, hexagonal bar iron, the back side weld together of the back side of half wheel rim and described outer half wheel rim in described, in described, half wheel rim face bonding has described ring stiffener, described outer half wheel rim face bonding has described set collar, described lock ring is pressed on described set collar, and described lock ring and set collar are fastening with described hexagonal bar iron.

In preferred embodiment of the utility model, the set collar of the positive welding of described outer half wheel rim is threaded.

In preferred embodiment of the utility model, the one side of described set collar is provided with the first groove, the one side of described lock ring is provided with the second groove, and described the second groove is relative with the first groove to be fitted in together, and described groove surface is processed into is with textured rough surface.

In preferred embodiment of the utility model, hold-down bolt pad on described lock ring, and the counterbore of described hold-down bolt pad is processed into and is in tilted layout.

In preferred embodiment of the utility model, described interior half wheel rim and outer half wheel rim adopt the moulding of high-elongation aluminium sheet to make.

The beneficial effect of the disclosed anticreep wheel rim of the utility model device is: 1, there is a lock ring with the bolt compression in the tire outside, has increased the binding force of tire; 2, can resist the infrabar impact, improve cross-country safety; 3, the anticreep performance of anticreep wheel rim is strong.

In accompanying drawing, the mark of each parts is as follows:

1, ring stiffener, 2, interior half wheel rim, 3, outer half wheel rim, 4, set collar, 5, lock ring, 6, spacer for bolt, 7, hexagonal bar iron, 8 first grooves, 9 second grooves.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.

See also Fig. 1, Fig. 2 and Fig. 3, a kind of anticreep wheel rim device, apparatus body adopts 6061 thick aluminium sheets of 5mm to make, comprise: ring stiffener 1, interior half wheel rim 2, outer half wheel rim 3, set collar 4, lock ring 5, spacer for bolt 6, hexagonal bar iron 7, the back side of half wheel rim 2 and the back side weld together of outer half wheel rim 3 wherein, in half wheel rim 2 fronts be welded with ring stiffener 1, on ring stiffener 1, equal-sized orifice ring can be set evenly, to alleviate the weight of anticreep wheel rim, 24 orifice rings that diameter is 14mm of even laying on ring stiffener 1 that the present embodiment is more excellent.Outer half wheel rim 3 fronts are welded with set collar 4, and set collar 4 is threaded.

Lock ring 5 is pressed on set collar 4, and lock ring 5 is fastening with set collar 4 use hexagonal bar irons 7.The front of set collar 4 arranges the first groove 8, lock ring 5 and set collar 4 over against one side be provided with the second groove 9, relative being fitted in together of the first groove 8 of the second groove 9 of lock ring 5 and set collar 4, the first groove 8 and the second groove 9 are processed into is with textured rough surface, can adopt annular knurl to be processed into straight burr or twill annular knurl to increase friction force.

Hold-down bolt pad 6 on lock ring 5, the counterbore of its hold-down bolt pad 6 is processed into and is in tilted layout, to adapt to the taper distortion that compresses aft closure ring.

The beneficial effect of the disclosed anticreep wheel rim of the utility model device is: 1, inside and outside half wheel rim adopts the moulding of high-elongation aluminium sheet to make, and has strengthened the performance of anticreep wheel rim; 2, there is a lock ring with the hexagonal bar iron compression in the outside of anticreep wheel rim, has strengthened the binding force of tire; 3, tire is difficult for tread flaking gas leakage under lower air pressure, thereby improves cross-country safety.

The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
