Abstract

The utility model provides a spin-formed wheel spoke with a thickened end surface and relates to an automobile fitting. A hub mounting hole and a vent hole are formed on the wall of the wheel spoke respectively, a wheel rim engagement segment is formed between the vent hole and the large end surface of the wheel spoke, and the part of the wheel rim engagement segment, which is adjacent to the larger end surface of the wheel spoke, is a straight part with a thickness larger than those of the other parts of the wheel rim engagement segment. When the spoke outer circle that is engaged with the wheel rim is machined, the length of the machined straight part is shortened and the machining load is reduced, so as to increase the production efficiency. Besides, after the wheel spoke is engaged with the wheel rim, the size of fillet weld of the wheel is increased because the end surface of the wheel spoke is thickened, so that the strength of fillet weld of the wheel is improved.

Description

The spinning spoke of end face thickening

Technical field

The utility model relates to a kind of vehicle body fittings, particularly a kind of spinning spoke of end face thickening.

Background technology

The spinning spoke of existing wheel, it cooperates section 3 with the whole wheel rim that wheel rim cooperates all is linear portions (referring to Fig. 1) that one section wall thickness equates, the outer bowlder that this spoke cooperates with wheel rim in Vehicle Processing, and the linear portion of Vehicle Processing is longer, the Vehicle Processing amount is bigger, and its production efficiency is lower.And because the end surface thickness of spoke is thinner, so the fillet weld size of its wheel fillet weld 5 is less, during with addition of thick wheel rim, and its weld strength deficiency.

Summary of the invention

The technical problems to be solved in the utility model is: provide the spinning spoke of a kind of end face thickening, to solve that the above-mentioned Vehicle Processing amount that prior art exists is big, production efficiency is lower and during with addition of thick wheel rim, the problem of its weld strength deficiency.

The technical scheme that solves the problems of the technologies described above is: a kind of spinning spoke of end face thickening, be respectively equipped with hub installing hole and breather port on its spoke wall, and the self-ventilation hole is the linear portion of one section thickness greater than wheel rim cooperation section remainder to being between the big end end face of spoke that wheel rim cooperation section, described wheel rim cooperate section in the part near the big end end face of spoke.

Owing to adopt said structure, the spinning spoke of the end face thickening of the utility model is compared with existing spinning spoke, has following beneficial effect.

Because it is one section thickness cooperates the section remainder greater than wheel rim linear portion in the part near the big end end face of spoke that wheel rim of the present utility model cooperates section, therefore when spin shaping, with the wheel rim cooperation section thickening of spoke near the big end end face of spoke, this spinning spoke is bowlder outside Vehicle Processing and spoke that wheel rim cooperates, the linear portion of Vehicle Processing shortens, its Vehicle Processing quantitative change is little, thereby has improved production efficiency.In addition, the spinning spoke that end face has been thickeied is with after wheel rim cooperates, because the end face of spoke has been thickeied, the fillet weld size of its wheel fillet weld can increase, thereby can improve the intensity of wheel fillet weld.

Below, the technical characterictic to the spinning spoke of the end face of the utility model thickening is further described in conjunction with the accompanying drawings and embodiments.

The specific embodiment

Embodiment one:

Disclosed among Fig. 2 is a kind of spinning spoke of end face thickening, be respectively equipped with hub installing hole 1 and breather port 2 on its spoke wall, and self-ventilation hole 2 is the linear portion 31 of one section thickness greater than wheel rim cooperation section remainder to being between the big end end face 4 of spoke that wheel rim cooperation section 3, described wheel rim cooperate section 3 in the parts near the big end end face 4 of spoke.

Present embodiment one described spinning spoke is cooperating the back (referring to Fig. 3～Fig. 4), because the end face of spoke has been thickeied, the fillet weld size of its wheel fillet weld 5 can increase, thereby can improve the intensity of wheel fillet weld with wheel rim.

Claims

1. the spinning spoke of end face thickening, be respectively equipped with hub installing hole (1) and breather port (2) on its spoke wall, and self-ventilation hole (2) are to being to it is characterized in that wheel rim cooperation section (3) between the big end end face of spoke (4): it is the linear portion (31) of one section thickness greater than wheel rim cooperation section remainder in the part near the big end end face of spoke (4) that described wheel rim cooperates section (3).
