Abstract
The utility model discloses a point contact type high-strength hub, and belongs to the technical field of automobile spare parts. The point contact type high-strength hub comprises a spoke and a rim. The spoke comprises an installation portion provided with bolt holes, embedded portions and a spoke disc portion, wherein the bolt holes are evenly distributed in the periphery of a central axle hole, the embedded portions are embedded into the spoke, and the installation portion is connected with the embedded portions through the spoke disc portion. Each bolt hole is formed in a circular boss which protruding to the outer axial side of the hub from the inner axial side of the hub. Four stress points are arranged at the periphery of each circular boss. The stress points are arranged on the inner axial side face of the flat portion of the installation portion. The point contact type high-strength hub has the advantages that light weight of the hub is achieved, the requirement for strength is met, the stress concentrated near the bolt holes can be dispersed due to the arrangement of the stress points, loads can be conveniently and evenly distributed, cracks are avoided, and therefore the fatigue life of the hub is prolonged.

Background technology
Automotive hub is safety component important in running car system, and the driving safety of automobile, ride comfort and occupant's traveling comfort are had to material impact.Wheel hub is generally worked under Random dynamic loads effect, and the principal mode that causes wheel hub to lose efficacy is endurance failure.Wheel hub must detect by multinomial performance before use, and wherein Rotary Bending Fatigue Test is an important detection.The endurance failure of wheel hub is mainly that Moment causes, and this moment of flexure is mainly caused by the predetermincd tension of the tie bolt of spoke and brake disc (or flange), therefore the bolt hole position of spoke mounting part is the higher region of stress under wheel hub static load state, belong to district of low life-span, under the effect of long-term High Rotation Speed live load, easily occur crackle at first and cause wheel hub to lose efficacy.
Utility model content
Technical problem to be solved in the utility model is for the problems referred to above, utilize finite element analysis computation, carry out again structural development and optimal design, and provide a contact high strength wheel hub, extenuate the stress concentration phenomenon at installation portion bolt hole position, improve load-carrying capacity and its rotating bending fatigue life of wheel hub.
The technical solution of the utility model is:
Point contact high strength wheel hub, comprise spoke and wheel rim, described spoke comprise have the bolt hole that is evenly distributed on central shaft hole periphery installation portion, be entrenched in fitting portion in wheel rim, connect the spoke dish portion of described installation portion and fitting portion, it is characterized in that: described in each, bolt hole is located at an axial inner side by wheel hub in the round boss of axial outside projection, the surrounding of described each round boss is provided with 4 stress points, and described stress point is arranged on the axial medial surface of flat on installation portion.The setting of stress point, is conducive to disperse to concentrate near the stress of bolt hole, is convenient to being uniformly distributed of load, prevents that crackle from producing, thus the fatigue life of improving wheel hub.
Further, each round boss described in the utility model 4 stress points around include in 2 punctuates and punctuates outward with 2, in described in all, punctuate and be distributed on the same circumference that is positioned at round boss inner side on radial direction, all described outer punctuating are distributed on the same circumference that is positioned at round boss outside on radial direction.
Further, stress point described in the utility model is fine strip shape projection, by axial outside, towards the compacting of axial inner side, is formed.
Further, installation portion described in the utility model is provided with the reinforced rib towards axial outside projection by axial inner side, round boss and reinforced rib along circumference apart from one another by distribution.Being provided with of reinforced rib is beneficial to increase wheel hub intensity, improves its load-carrying capacity.
Further, spoke dish described in the utility model portion is to the arch convex hoop shape of spoke outside projection, which is provided with a plurality of breather ports, and described a plurality of breather ports distribute along even circumferential centered by central shaft hole.Being provided with to be beneficial to of breather port alleviates wheel hub weight, realizes light-weight design.
Further, installation portion described in the utility model, fitting portion and spoke dish portion are structure as a whole.
The beneficial effects of the utility model are: breather port is set and realizes wheel hub lightweight, also utilize reinforcing rib structure to meet requirement of strength simultaneously, and the setting of stress point can disperse to concentrate near the stress of bolt hole, be convenient to being uniformly distributed of load, prevent that crackle from producing, thus the fatigue life of improving wheel hub.
Applicant has carried out Rotary Bending Fatigue Test to high strength high fatigue life wheel hub described in the utility model, control group is the common wheel hub of the same specification of unstressed point, two wheel hub exemplars are carried out to fatigue test under the condition of constant moment of flexure 1571N.m, rotating speed 200rpm, the common wheel hub of result is unstressed point is after 70220 rotations, spoke breaks, and wheel hub of the present utility model just occurs breaking after 122400 rotations.Test figures absolutely proves, after structural development and optimal design, be significantly improved the fatigue life of wheel hub of the present utility model.
