background technology:

As shown in Figure 1 and Figure 2, for the structural representation of four gasbags structure drive axle and bracket after existing medium bus, drive axle 101 is connected by supporting plate 103 and U-bolt 104 with bracket 102, air bag component 105 is arranged on the two ends of bracket 102, therefore, corresponding four air bag components 105 of drive axle 101, this is the reason that the cost of air bag passenger vehicle is not easy to reduce.The vibration produced in bus driving process, passes to vehicle frame by air bag component 105, thus reaches damping object, is conducive to the traveling comfort improving passenger vehicle.

Wherein, bracket 102 is that passenger vehicle is equipped with one of critical component of air suspension, and bracket 102 is yi word pattern bracket, what the yi word pattern bracket on existing medium bus all adopted is casting bracket, casting bracket heavier-weight, foundry technique bothers, and is unfavorable for that passenger vehicle weight-saving develops.

utility model content:

In sum, in order to overcome the deficiency of prior art problem, the utility model provides four gasbags suspension yi word pattern punching press bracket after a kind of medium bus, it is that original yi word pattern casting bracket is modified as yi word pattern punching press bracket, on punching press bracket, be welded and fixed U-bolt mounting pipe simultaneously, air bag mounting pipe, on, the parts such as lower platen, structure is simple, easy to use, punching press bracket is welded by after two block plate punch formings, after welding, punching press bracket becomes hollow structure, the weight of bracket can be effectively reduced, thus promote the lightweight development of passenger vehicle.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

Four gasbags suspension yi word pattern punching press bracket after a kind of medium bus, wherein: comprise bracket body, described bracket body is yi word pattern structure, the two ends of bracket body respectively arrange an air bag mounting pipe, end face in the middle part of bracket body is fixed with top board, bottom surface in the middle part of bracket body is fixed with lower platen, U-bolt mounting pipe is provided with between top board and lower platen, described bracket body top is fixed with bumper upper bracket, and between described top board and lower platen, in the middle part of bracket body, side is fixed with track bar bracket.

Further, described bracket body comprises the first half and lower part, and the first half is identical with lower part structure, and its cross sectional shape is " U " type, the first half and lower part interfix after punch forming respectively, and the cross sectional shape after the first half and lower part interfix is " mouth " font.

Further, the planform of described track bar bracket is " U " type.

The beneficial effects of the utility model are:

1, original yi word pattern casting bracket is modified as yi word pattern punching press bracket by the utility model, on punching press bracket, be welded and fixed the parts such as U-bolt mounting pipe, air bag mounting pipe, upper and lower pressing plate simultaneously, structure is simple, easy to use, punching press bracket is welded by after two block plate punch formings, after welding, punching press bracket becomes hollow structure, can effectively reduce the weight of bracket, thus promotes the lightweight development of passenger vehicle.

2, the utility model structure is simple, easy to use, has the features such as integrated level is high, lightweight, good rigidity, can effectively reduce complete vehicle weight, can greatly improve car load traveling comfort and fuel economy.

accompanying drawing illustrates:

Fig. 1 is the structural representation of four gasbags structure drive axle and bracket after existing medium bus;

Fig. 2 is the elevational schematic view of Fig. 1;

Fig. 3 is structural representation of the present utility model;

Fig. 4 is the schematic cross-section of bracket body of the present utility model.

detailed description of the invention:

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 3, Figure 4, four gasbags suspension yi word pattern punching press bracket after a kind of medium bus, comprise bracket body 1, bracket body 1 is yi word pattern structure, bracket body 1 comprises the first half 8 and lower part 9, and the first half 8 is identical with lower part 9 structure, and its cross sectional shape is " U " type, the first half 8 and lower part 9 interfix after punch forming respectively, and the cross sectional shape after the first half 8 and lower part 9 interfix is " mouth " font.

The two ends of bracket body 1 respectively arrange an air bag mounting pipe 2, end face in the middle part of bracket body 1 is fixed with top board 3, bottom surface in the middle part of bracket body 1 is fixed with lower platen 4, U-bolt mounting pipe 5 is provided with between top board 3 and lower platen 4, described bracket body 1 top is fixed with bumper upper bracket 6, between described top board 3 and lower platen 4, in the middle part of bracket body 1, side is fixed with track bar bracket 7, and the planform of track bar bracket 7 is " U " type.

During production, first steel plate stamping is pressed into the first half 8 and lower part 9 structure of bracket body 1 by punching machine and diel, then the first half 8 and lower part 9 are interlocked, be welded and fixed, finally again top board 3, lower platen 4, U-bolt mounting pipe 5, air bag mounting pipe 2, track bar bracket 7 and bumper upper bracket 6 and bracket body 1 are welded and fixed, so far complete of the present utility model manufacturing.

Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
