Abstract

The utility model provides a vehicle body longitudinal beam assembly which comprises a first component and a second component, wherein one end of the first component is fixedly connected with one end of the second component; and the other end of the second component is fixedly connected with a reinforcing member. In the vehicle body longitudinal beam assembly provided by the embodiment of the utility model, the reinforcing member is additionally arranged at the end part of the second component, thus the structural strength of the vehicle body longitudinal beam assembly can be improved without changing the material. Meanwhile, the structure can prevent the damage of a connecting piece so as to prolong the service life of the vehicle longitudinal beam assembly.

Description

A kind of chassis runner assembly

Technical field

The utility model relates to the vehicle mechanical technical field, especially relates to a kind of chassis runner assembly.

Background technology

Along with The development in society and economy, vehicle has got into huge numbers of families.Particularly, improved the popularity rate of private car especially along with the lifting of the automobile localization rate of parts and components.The chassis runner of existing self-propelled vehicle is the important component part on chassis, and middle-and-high-ranking vehicle is in order to improve the inner space, and longeron can reach 2079mm or longer usually.Existing vehicle girder work is as shown in Figure 1, comprises first assembly 1 and second assembly 2, and this first assembly 1 and second assembly 2 are microscler blanked part.As shown in Figure 1, these two microscler blanked parts are fixing through attaching parts 3, and can also weld other annexes.The vehicle longeron is the main supporting part of vehicle body inner frame, and a lot of parts of vehicle body all are fixed on the vehicle longeron.Existing chassis runner is in order to improve the life-span, and second assembly 2 is processed by high strength material, can improve the intensity of second assembly 2 like this, and the A end that prevents second assembly 2 is because the long-term stressed easy damage that causes.But it is unsatisfactory through the material result that changes second assembly 2 like this.This is because second assembly 2 is also fixing through the attaching parts 3 and first assembly 1, though second assembly 2 adopts high strength material can satisfy requirement of strength, because thickness of slab and intensity are high, causes attaching parts 3 to be easily damaged.

The utility model content

To defective that exists in the prior art and deficiency, the purpose of the utility model is that proposition is a kind of through changing the chassis runner assembly that structure improves structural strength, can be widely used in automobile and mechanical industry.

In order to achieve the above object; The utility model provides a kind of chassis runner assembly, comprising: first assembly and second assembly, and an end of first assembly is captiveed joint with an end of second assembly; It is characterized in that other end captive joint one reinforcement of said second assembly.

Preferred as technique scheme, the upper surface of said reinforcement and the said second assembly underside shape are suitable to be fixed in the lower surface of said second assembly.

Preferred as technique scheme, said reinforcement is welded in the said second assembly lower surface.

Preferred as technique scheme, said reinforcement comprises a sheet body, said sheet noumenon both sides have spacing preiection.

The beneficial effect of the technical scheme that the utility model embodiment provides is: the chassis runner assembly of the utility model embodiment has increased a reinforcement in the end of second assembly, need not to change the structural strength that material can improve the chassis runner assembly like this.Simultaneously, such structure can prevent the damage of attaching parts again, improves the life-span of vehicle longeron assembly.

Description of drawings

Fig. 1 is the structural representation of existing chassis runner assembly;

Fig. 2 is the structural representation of the utility model embodiment;

Fig. 3 is the structural representation of reinforcement among Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing the utility model preferred embodiment one is further specified.

The utility model embodiment has proposed a kind of chassis runner assembly, and its structure comprises shown in Fig. 2-3: first assembly 1 and second assembly 2, and an end of first assembly 1 captives joint through attaching parts 3 with an end of second assembly 2.As shown in Figure 2, the other end of said second assembly 2 is fixedly connected with the reinforcement 4 of structure as shown in Figure 3.Comparison diagram 2 can find out among Fig. 2 that with shown in Figure 1 portion increases a reinforcement 4 in the A bottom of Fig. 1.Like Fig. 2, shown in Figure 3, the upper surface of said reinforcement 4 and said second assembly, 2 underside shapes are suitable to be fixed in the lower surface of said second assembly 2.Concrete, this reinforcement 4 can be welded in the lower surface of said second assembly 2.As shown in Figure 3, this reinforcement 4 comprises a sheet body, said sheet noumenon both sides have spacing preiection.Can prevent that like this this reinforcement 4 is subjected to displacement with respect to this second assembly 2, improve bonded assembly intensity.Simultaneously can be convenient for assembly.

Certainly; The utility model also can have other embodiment; Under the situation that does not deviate from the utility model spirit and essence thereof; The person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the claim of the utility model.

Claims
