Abstract
Vehicle wheel hub is provided in present invention, wherein a wheel (2) is inserted into inner side of a rim (1) with a valve setup hole (10) thereon, the welding surface of the rim (1) and the wheel (2) is welded in such a manner that welding starts from one side of the valve setup hole (10) and ends at the other side thereof. A welding joint end portion (31) which welds the wheel (2) and the rim (1) is formed at both sides of the valve setup hole (10). The invention is characterized in that a groove (5) for solder inflow is provided at periphery of the wheel (2) at outer side of the welding joint end portion (31). Thus, concentrated stress at the welding joint end portion (31) which welds the wheel (2) and the rim (1) is absorbed and dispersed so as to prevent service life reducing of the wheel hub due to crack, moreover the invention has advantages of easy manufacturing and mass producing.
Description
Technical field
The present invention relates to a kind of automotive hub, by wheel rim be welded in the two-piece type wheel hub that wheel rim in-to-in wheel disc constitutes, owing to can disperse to be absorbed in the stress of concentrating on the solder bond end of wheel rim and wheel disc welding, thereby can prevent to shorten, but and be easy to make and stock production owing to crackle makes the endurance life of wheel hub.
Background technology
Usually, as shown in Figure 1, the two-piece type wheel hub is made in the following manner: after with the high-pressure machine raw material of aluminum alloy being forged, use roller that thickness is ironed, then, be cut into certain size, form wheel rim 1 through expansion and spinning operation, will the as cast wheel disc 2 insert in the forging wheel rim 1 of het expansions and fixing (contraction fit operation), weld wheel rim 1 then and wheel disc 2 is made the two-piece type wheel hub.
Above-mentioned two-piece type forged hub is more in light weight than general casting hub, thereby can make the vehicle lightweight, and mechanical characteristics is outstanding, and outward appearance grace, competitiveness of product are strong.
Yet the problem that the two-piece type forged hub exists is behind the fatigue test, will produce the fatigue cracking that causes owing to moment of deflection in wheel disc 2 and the weld 3 that wheel rim 1 intersects.
Particularly, the welding starting point of formation when resulting from welding wheel disc 2 with wheel rim 1 and the terminal point that welding finishes are concentrated in above-mentioned be full of cracks, and promptly the solder bond end 31.
Usually, owing to be formed with valve on wheel rim 1 hole 10 is set, is used to be provided with the valve that air is injected inside tires, therefore when welding wheel rim 1 and wheel disc 2, the side that hole 10 is set from valve begins to be soldered to the opposite side welding end that valve is provided with hole 10.
Therefore, be formed with solder bond end 31 in the both sides that valve is provided with hole 10.
Though, implement making the solder bond end stacked not form the welding method of solder bond end mutually once in a while, the weld will block valve hole 10 will be set in this case, and the position that valve is provided with hole 10 must change.Yet the position that welding is provided with hole 10 also is not easy to change, because because of there is the problem of wheel hub balance variation in stacked weld, so use the welding method that the both sides end welding in hole 10 is set at valve inevitably.
The applicant for solve above-mentioned prior art problems in first to file a kind of automotive hub (with reference to Korea S's application for a patent for invention 2005-0059828 number), as shown in Figures 2 and 3, it has following structure: wheel disc 2 is inserted in has the inboard that valve is provided with the wheel rim 1 in hole 10, the face of weld of wheel rim 1 and wheel disc 2 begins to be soldered to the mode that opposite side that valve is provided with hole 10 finishes according to the side that hole 10 is set from valve and welds, the both sides that hole 10 is set at valve form solder bond end 31, wherein, on the wheel disc 2 in wheel disc 2 and 31 outsides, solder bond end of wheel rim 1 solder bond, be formed with the dashpot 25 that absorbs and disperse to concentrate on the stress of solder bond end 31.The both side ends of dashpot 25 is formed with circular enlarged portion 250.
In this invention in first to file, because concentrating on the stress of wheel rim 1 and the solder bond end 3 of wheel disc 2 welding can be formed on dashpot 25 on the wheel disc 2 and absorb buffering and disperse simultaneously, thereby can prevent to crack towards solder bond end 31, significantly prolonged the endurance life of wheel hub owing to stress concentration.
Yet there are many problems in above-mentioned invention in first to file in manufacturing process.Promptly, because the operation that forms the dashpot 25 that width is narrow and length is long and form enlarged portion 250 at the both ends of dashpot 25 on the wheel disc 2 that is formed with solder bond end 31 is difficulty and need more production time very, therefore, the capacity rating of product is extremely low, is not suitable for stock production.
Summary of the invention
In order to solve aforesaid existing problem, the applicant improves the invention in first to file.The purpose of this invention is to provide a kind of automotive hub, the stress that concentrate its solder bond end that can disperse to be absorbed in wheel rim and wheel disc welding, thus can prevent because crackle shortens the endurance life of wheel hub, and be easy to manufacturing and can stock production.
To achieve these goals, the present invention has following structure.Promptly, wheel disc is inserted in has the wheel rim inboard that valve is provided with the hole, the face of weld of wheel rim and wheel disc begins to be soldered to valve according to the side that the hole is set from valve and the mode that the opposite side in hole finishes is set is welded, the both sides that the hole is set at valve are formed with the solder bond end, wherein, the periphery of the wheel disc outside the solder bond end of wheel disc and wheel rim solder bond is formed with the groove that flows into for scolder.
According to the present invention, can absorb and disperse the concentrated stress in solder bond end of welding wheel rim and wheel disc, thereby can prevent to shorten, but and be easy to make and stock production owing to crackle makes the endurance life of wheel hub.

Hereinafter with reference to accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Fig. 4 is the section drawing of wheel hub of the present invention, and Fig. 5 is the amplification sectional view of main portion of the present invention.
As shown in Figure 4 and Figure 5, structure of the present invention is as follows, wheel disc 2 is inserted in has the inboard that valve is provided with the wheel rim 1 in hole 10, the face of weld of wheel rim 1 and wheel disc 2 begins to be soldered to the mode that opposite side that valve is provided with hole 10 finishes according to the side that hole 10 is set from valve and welds, and the both sides that hole 10 is set at valve form solder bond end 31.Wherein, be formed with the groove 5 of confession scolder inflow at the wheel disc 2 and the periphery of the wheel disc 2 in 31 outsides, solder bond end of wheel rim 1 solder bond.
In addition, the depth D of groove 5 is in the scope of 8～10mm, and width W is in the scope of 10～15mm.The inside surface of side wall that is positioned at the welding latter end forms curved surface 51.
The present invention with said structure, when wheel rim 1 and wheel disc 2 were carried out the solder bond operation, the scolder of fusing flowed into the inside that is formed at the groove 5 on the wheel disc, and form smooth surface and uniform shapes in conjunction with end 31, to prevent that stress concentration is in conjunction with the end.
The present invention is not limited to the foregoing description, can carry out various distortion and enforcement in the scope that technical conceive of the present invention allows.
As mentioned above,, can absorb and disperse the concentrated stress in solder bond end of welding wheel rim and wheel disc, thereby can prevent to shorten, but and be easy to make and stock production owing to crackle makes the endurance life of wheel hub according to the present invention.
