Abstract
The utility model relates to an explosion prevention tyre hub which comprises a wheel rim. The explosion prevention tyre hub is characterized in that a support ring fixedly connected with the wheel rim is arranged along the periphery of the wheel rim. Because the support ring is arranged on the wheel rim, once tyre burst happens, the support ring with larger diameter, instead of the wheel rim, is in contact with the ground; and because the diameter of the wheel rim is not changed obviously and the contact area of the support ring and the ground is increased simultaneously, the possibility of vehicle lose control is greatly reduced and the safety performance of vehicles is improved compared with the prior art.
Description
Technical field:
The utility model relates to a kind of auto parts and components, particularly a kind of wheel hub of automobile.
Background technology:
In a single day automotive wheel relates to the vitals of ride safety of automobile, blows out during galloping, consequence is the serious accident of car crash normally.At present, wheel mainly is made of wheel hub and tire, and wheel hub comprises spoke and wheel rim, and the cross section of wheel rim is a U-shaped, and tire is stuck in the inside of wheel rim, form an annular, the cross section is approximately the confined space of O shape.The wheel hub of this structure, in case blow out, wheel rim is with the moment kiss the earth, because the diameter of wheel rim is significantly smaller than the diameter of former tire, simultaneously wheel rim and ground-surface friction force also are significantly smaller than tire and ground-surface friction force, so vehicle easily can get out of hand in moment, and accident creates greater casualties.
Summary of the invention:
The purpose of this utility model provides a kind of runflat wheel hub that can reduce accident occurrence probability when blowing out.
The realization the technical solution of the utility model is, a kind of runflat wheel hub comprises wheel rim, it is characterized in that, along one week of wheel rim, be provided with the bracing ring affixed with it.
The utility model is owing to be provided with bracing ring on wheel hub, in a single day thereby when blowing out, the wheel kiss the earth will no longer be wheel rim, but the bigger bracing ring of diameter, because the variation of wheel diameter is less relatively, bracing ring and ground-surface area of contact increase simultaneously, thereby compare with prior art, possibility to lose control of one's vehicle reduces greatly, and the safety performance of vehicle ' is improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
Number in the figure: 10 tires, 20 wheel rims, 30 bracing rings, 31 clamping rings, 32 wheel rims, 33 rubber layers, 34 holes.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the external diameter of bracing ring 30 is greater than the external diameter of wheel rim 20, less than the external diameter of tire 10; The cross section of described bracing ring 30 is a T shape, and described bracing ring 30 comprises clamping ring 31 and wheel rim 32, and clamping ring 31 is provided with hole 34, to alleviate the weight of wheel hub; For strengthening wheel rim 32 and ground-surface friction force, the surface of described wheel rim 32 is provided with rubber layer 33, and the thickness of rubber layer generally is not less than 5 millimeters.Spacing between rubber layer 33 on the wheel rim 32 and tire 10 inside faces, adjust according to vehicle and the different of tyre model, both guaranteed the elasticity of tire, make the traveling comfort of vehicle unaffected, in the time of guaranteeing to blow out again, the wheel of blowing out is less to the influence of vehicle, improves the safety performance of vehicle effectively.
