Abstract
The utility model discloses a sectional frame longitudinal beam. The sectional frame longitudinal beam comprises a front longitudinal beam (1) and a rear longitudinal beam (2) which are fixedly connected with each other, wherein the front longitudinal beam (1) and the rear longitudinal beam (2) are connected together through an overlap structure; and the rearward face (4) and upper and lower wing surfaces (5) of the front longitudinal beam (1) are overlapped with those of the rear longitudinal beam (2), and the overlapped joint is riveted by a rivet or welded. The sectional frame longitudinal beam ensures that leftovers can be greatly reduced while machining manufacturability and coherence can be remarkably improved. Based on the sectional frame longitudinal beam, the utility model also provides a sectional frame with a structure of the sectional frame longitudinal beam.
Description
Technical field
The utility model relates to automotive field, and is concrete, relates to a kind of segmented bicycle frame longeron and segmented bicycle frame.
Background technology
In the total of automobile, vehicle frame plays each parts that supporting connects automobile, bears the effect from the various load inside and outside the car.At present, have only body-chassis frame construction to use vehicle frame usually, vehicle frame is made of the frame mode that connects a plurality of crossbeams between the longeron.Wherein, because longeron is whole segmentation, therefore in the process of processing longeron, traditional method cuts out the last punch forming of respective shapes with plasma cutter again for cutting out out earlier suitable plate.The material mode of cutting out that this is traditional exists the manufacture craft difference and can produce shortcomings such as large tracts of land clout.Owing to adopted the mode of plasma cutting, consistency of product can not well be guaranteed in addition.
The utility model content
The purpose of this utility model provides a kind of segmented bicycle frame longeron.This segmented bicycle frame longeron has adopted the longeron segmented structure, like this, just can carry out punching press respectively to each section of longeron when the processing vehicle frame, to improve the degree of utilization of material.
To achieve these goals, the utility model provides a kind of segmented bicycle frame longeron, and this segmented bicycle frame longeron comprises leading portion longeron and the back segment longeron that is mutually permanently connected.
Preferably, leading portion longeron and back segment longeron link together by bridging arrangement.
Preferably, the outside of belly and the last lower aerofoil of the outside of belly of leading portion longeron and last lower aerofoil and back segment longeron overlap mutually, and rivet or adopt by rivet in mutual lap-joint and be welded to connect.
The utility model also provides a kind of segmented bicycle frame, and this segmented bicycle frame comprises the chassis side rail of both sides and be connected in a plurality of crossbeams between the chassis side rail of these both sides that wherein each chassis side rail is according to segmented bicycle frame longeron described in the utility model.
In technique scheme, owing to adopted the longeron segmented structure, like this, when the processing vehicle frame, just can carry out punching press respectively to the leading portion and the back segment of longeron, processing technology is easy to realize that the mould of use is less relatively that consistency of product also can be guaranteed, compare with the processing mode of traditional unit frame longeron, the degree of utilization of material has also obtained very big lifting.
Description of drawings
Accompanying drawing is to be used to provide further understanding of the present utility model, and constitutes the part of specification sheets, is used from explanation the utility model with the following specific embodiment one, but does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the segmented bicycle frame structural representation of the utility model preferred implementation;
Fig. 2 is that chassis side rail is cut out the material scheme drawing in the prior art;
Fig. 3 is that the vehicle frame leading portion longeron and the vehicle frame back segment longeron of the utility model vehicle frame cut out the material scheme drawing.

The specific embodiment
Based on traditional unit frame longeron, the utility model provides a kind of new segmented bicycle frame longeron, from structure and two angles of processing technology body frame structure for automotive is improved, thereby the manufacturability of body frame structure for automotive and conformability are significantly improved.
Below in conjunction with accompanying drawing preferred implementation of the present utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of segmented bicycle frame longeron, and this segmented bicycle frame longeron comprises leading portion longeron 1 and the back segment longeron 2 that is mutually permanently connected.
In this technical scheme, owing to adopted the longeron segmented structure, like this, when the processing vehicle frame, just can carry out punching press respectively to the leading portion and the back segment of longeron, processing technology is easy to realize that the mould of use is less relatively that consistency of product also can be guaranteed, compare with the processing mode of traditional unit frame longeron, the degree of utilization of material has also obtained very big lifting.
Preferably, leading portion longeron 1 and back segment longeron 2 can link together by bridging arrangement.Further preferably, the outside of belly 4 of leading portion longeron 1 and last lower aerofoil 5 overlap mutually with the outside of belly 4 and the last lower aerofoil 5 of back segment longeron 2, and rivets or adopt by rivet in mutual lap-joint and be welded to connect.
Because the connection mode that the front and back section of the utility model longeron preferably adopts the outside of belly and last lower aerofoil to rivet simultaneously or weld, so meet the demands fully on the intensity.
In the course of processing of segmented bicycle frame longeron of the present utility model, the mode that the section beam is processed respectively before and after adopting.Wherein, fold the mode of dashing after processing leading portion longeron 1 needs to use whole blanking, processing back segment longeron 2 then can not have waste material to produce directly with the continuous shear of plate shear in theory.Fig. 3 is that the vehicle frame leading portion longeron and the vehicle frame back segment longeron of the utility model vehicle frame cut out the material scheme drawing, the sheet material bigger with respect to the employed area of traditional approach chassis side rail shown in Figure 2 carries out the processing clout 11 that whole cutting produced, 12,13 of processing clouts among Fig. 3 will lack a lot.
In addition, the utility model also provides a kind of segmented bicycle frame, and this segmented bicycle frame comprises the chassis side rail of both sides and be connected in a plurality of crossbeams between the chassis side rail of these both sides that wherein each chassis side rail all can adopt above-mentioned segmented bicycle frame longeron.
Preferred implementation of the present utility model has below been described in conjunction with the accompanying drawings; but; the utility model is not limited to the detail in the above-mentioned preferred implementation; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.In addition, the concrete technical characterictic of each that describe in the above-mentioned specific embodiment under the situation that meets the utility model application purpose, can carry out combination in any to form other selectable embodiment.Protection domain of the present utility model is limited by claim.
