Abstract
The utility model relates to a motorcycle frame, comprising a stand pipe, a main beam, a connecting frame and a back bracket; the stand pipe is welded at the front top of the main beam; the connecting frame is tightly connected with the two sides of the main beam by a screw bolt; the back bracket is positioned at the rear end of the frame and is welded at the connecting frame at the two sides of the main beam. To a certain extent, the frame reduces the frame welding accumulated error which is caused by welding thermal deformation; the position accuracy between the parts of the frame is improved to certain extent, and relative process flow is reduced; simultaneously, the parts of the frame has a certain universal interchangeability, so that the waste of resources which is caused by the change of the mould of motorcycle can be avoided.
Description
Technical field
The utility model relates to a kind of frame of motorcycle.
Technical background
Existing frame of motorcycle is divided into precursor portions and opisthosoma's branch, precursor portions comprises standpipe and girder, opisthosoma divides and comprises after poppet and down tube, standpipe is positioned at the preceding upper end of girder, after poppet is positioned at the vehicle frame rear portion, and be connected with girder by down tube, constituting between each parts of vehicle frame all is that mode with welding connects.Because each member on each parts and the parts will produce thermal deformation inevitably in welding process, make vehicle frame integral body after welding is finished, will produce bigger welding cumulative errors between each parts of formation vehicle frame, the mutual alignment precision is wayward between each parts, if will guarantee the positional precision between each parts, certainly will make the complex manufacturing technologyization of vehicle frame; Simultaneously, because vehicle frame is promptly finalized the design after being welded into integral body, do not possess general interchangeability, if this moment is because the variation of the market demand or other are former thereby need to change vehicle, and the change of this vehicle only need be changed under the situation that a certain parts in the vehicle frame can realize, component parts in the vehicle frame of welding fabrication can not generally exchange, and this will cause the waste of resource.
The utility model content
The purpose of this utility model provides a kind of frame of motorcycle, because the vehicle frame that the welding heat distortion causes welds error, makes the component parts of vehicle frame have certain general interchangeability to reduce to a certain extent simultaneously.
Frame of motorcycle described in the utility model, the after poppet that comprises standpipe, girder and the composition vehicle frame opisthosoma branch of forming the vehicle frame precursor portions, standpipe is welded on the preceding upper end of girder, after poppet is positioned at the vehicle frame rear portion, vehicle frame opisthosoma divides and also comprises the link span that is welded as a whole with after poppet, and this link span bolt up is connected both sides, girder rear portion.
The utility model is owing to have said structure, in the manufacturing process of vehicle frame, be with after girder and the standpipe welding, to be connected the girder both sides with the integrally welded link span bolt up of after poppet again, and no longer be welded to connect, so reduced to a certain extent because the vehicle frame that the welding heat distortion causes welds cumulative errors, the positional precision between each parts of vehicle frame is able to raising to a certain degree, and has reduced corresponding technological process; Simultaneously,, thereby make the component parts of vehicle frame have certain general interchangeability, avoided owing to vehicle changes the wasting of resources that causes owing to the vehicle frame component parts of bolt together can be changed as required.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is that the master who the utlity model has a kind of concrete structure of frame of motorcycle of the frame that removably connects looks scheme drawing;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, this frame of motorcycle comprises standpipe 1, the girder 2 of forming the vehicle frame precursor portions and forms the after poppet 5 that vehicle frame opisthosoma divides, standpipe 1 is welded on the preceding upper end of girder 2, after poppet 5 is positioned at the vehicle frame rear portion, vehicle frame opisthosoma divides and also comprises two link spans 4 that are welded as a whole with after poppet 5, and this link span 4 is fastenedly connected in both sides, girder 2 rear portion (nut that spins with bolt 3 has been welded on girder 2 relevant positions) with two bolts 3 respectively.
Claims (1)
1, a kind of frame of motorcycle with the frame that removably connects, comprise standpipe (1), the girder (2) of forming the vehicle frame precursor portions and form the after poppet (5) that vehicle frame opisthosoma divides, standpipe is welded on the preceding upper end of girder, after poppet is positioned at the vehicle frame rear portion, it is characterized in that: vehicle frame opisthosoma divides and also comprises the link span (4) that is welded as a whole with after poppet, and this link span is fastenedly connected in both sides, girder rear portion with bolt (3).
