The utility model content
The utility model is in order to solve existing commercial-vehicle cab rear support part complex structure, and materials are more, and Rigidity and strength is not satisfactory deficiency all, and a kind of commercial-vehicle cab rear support part is provided.
The technical matters of the required solution of the utility model can be achieved through the following technical solutions:
A kind of commercial-vehicle cab rear support part, it is characterized in that, comprise: be fixed on vertically two side flangings of large beam sides, the U-shaped cavity that is surrounded by two side and antetheca that is connected with two side flangings, the outline of the parts that described cavity upper end profile and rear support part are to be supported is identical.
In the utility model, in order to strengthen the Rigidity and strength of rear support part, described two side flangings and cavity are that the veneer punching press is one-body molded.
In the utility model, the antetheca of described cavity be from the upper end towards the dip plane of flange lopsidedness, it is large that the width of described antetheca becomes from top to bottom gradually, with the Rigidity and strength of effective lifting rear support part.
In the utility model, described cavity both can be that centrosymmetric structure also can be non-centrosymmetrical structure.
In the utility model, be equipped with lightening hole on the antetheca of described cavity and the two side, alleviating the weight of rear support part, and promote rigidity; Lightening hole on the described antetheca be arranged on antetheca vertically in the heart.
In the utility model, described cavity antetheca and lower end, two side connection location adopt the circular arc of different radii near the mounting hole place, and then the mounting plane area around increasing.
In the utility model, the junction of described cavity antetheca and two side is provided with recess, to reduce the punching press resilience in the course of processing, avoids outer wall distortion in the course of processing.
Commercial-vehicle cab rear support part of the present utility model, form cavity structure by integrated mode, simplified the structure of rear support part, reduced the use of material, when alleviating rear support part weight, improve the Rigidity and strength of rear support part, guaranteed the work in rear support part long-term stability, further guaranteed the stable of whole cab structure.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the perspective view of the utility model the first embodiment.
Fig. 2 is the back view of the utility model the first embodiment.
Fig. 3 is the perspective view of the utility model the second embodiment.
Fig. 4 is the back view of the utility model the second embodiment.
The specific embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Purport of the present utility model is, by to the complex structure degree of existing commercial-vehicle cab rear support part, materials what, and the bulk analysis of Rigidity and strength, for existing commercial-vehicle cab rear support part complex structure, materials are more, and the Rigidity and strength of rear support part is the problem such as undesirable all, provides a kind of simple in structure, materials are less, possess the preferably rear support part of Rigidity and strength characteristic.
Referring to Fig. 1 and Fig. 2, in the utility model the first embodiment, the rear support part comprises two side flanging 1a, flange 1a is fixed on crossbeam (not illustrated) side vertically, flange 1a is provided with a plurality of mounting hole 11a, flange 1a and crossbeam fixing then runs through mounting hole realization corresponding on flange 1a and the crossbeam by bolt of rear end plate.
Two side flanging 1a connect two side 2a, two side 2a and antetheca 3a surround the U-shaped cavity jointly thus, the outline of the parts that the upper end profile of cavity and rear support part are to be supported is identical, in the present embodiment, the profile of cavity upper end is circular-arc, and parts to be supported should be outline for circular parts, such as parts such as rollers, only be exemplary illustration in the present embodiment, be not limitation of the utility model.
In order to solve the existing not good problem of rear support part Rigidity and strength, two side flanging 1a, two side 2a and antetheca 3a adopt the body formed mode of a veneer punching press, cavity antetheca 3a is that the upper end is towards the dip plane of flange 1a lopsidedness, and it is large that the width of antetheca 3a becomes from top to bottom gradually, can effectively promote like this Rigidity and strength of rear support part.
Referring to Fig. 3 and Fig. 4, the second embodiment of the present utility model and the first embodiment are similar, the rear support part comprises that two side flanging 1b, two side 2b and antetheca 3b adopt the integrated mode of veneer punching press to consist of, antetheca 3b adopts the upper end towards the dip plane of flange 1b lopsidedness, and the width of antetheca 3b becomes large from top to bottom gradually.
What two kinds of embodiments were different is, in the first embodiment, and symmetrical structure centered by the cavity that two side 2a and antetheca 3a surround, and in the second embodiment, the cavity that two side 2b and antetheca 3b surround is the non-centrosymmetry structure.In two kinds of embodiments, be equipped with lightening hole 4 on the antetheca of cavity and the two side, can alleviate like this weight of rear support part and promote simultaneously rigidity, in two kinds of embodiments, the lightening hole on the antetheca be arranged on antetheca vertically in the heart.
In addition, the difference of two kinds of embodiments also is: in the first embodiment, cavity antetheca 3a and two side 2a connection location have adopted the circular arc 5a of different radii near the 11a of mounting hole place, and then the mounting plane area around can increasing; In the second embodiment, the junction of cavity antetheca 3b and two side 2b is provided with recess 6b, can reduce like this punching press resilience in the course of processing, avoids outer wall distortion in the course of processing.
