Abstract
The utility model relates to a frame camber beam of a tricycle, specifically relates to a frame camber beam of a tricycle for preventing weld defects, which comprises a rectangular pipe having two buckles, wherein a rectangular pipe I is parallelly connected with a rectangular pipe III through a rectangular pipe II, the rectangular pipe I, the rectangular pipe II and a rectangular pipe III extending to the same direction are in the same flat surface and have no soldering joints, thereby preventing the weld defects and increasing the intensity of the buckle part because of the cold-work hardening in the process of bending. The structure has the advantages that the labor, the raw material and the space can be saved, and the designers are convenient to arrange the overall set.
Description
Technical field:
The utility model relates to a kind of chassis side rail of three-wheel vehicle, is specifically related to a kind of tricycle frame's camber beam that can avoid weld defect.
Technical background:
Tricycle frame's longeron since be subjected to the liftoff minimum clearance of diesel engine and operator's compartment install and the driver and conductor easy for going up and down, fitness for purpose is low and near the vehicle tail end height near the headstock end.What occur in the market is welded structure often, and welded structure exists solder joint, makes the bending part intensity difference, and raises the cost, wasting space, and influence attractive in appearance.
Summary of the invention:
The purpose of this utility model is to overcome deficiency of the prior art and tricycle frame's camber beam of a kind of bending part intensity height, structure labor and material saving being provided and saving the space.
The purpose of this utility model is achieved in that and comprises that rectangular tube, rectangular tube have two bendings, and rectangular tube I is parallel with rectangular tube III and connect by rectangular tube II, and rectangular tube I, rectangular tube II and rectangular tube III extend and in same plane to same direction.
The utlity model has not welding, avoided weld defect; And in the bending process, be improved owing to flow harden effect bending part intensity; This structure labor and material saving, saving space are convenient to the designer and are carried out the advantage that complete machine is arranged.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises rectangular tube 1, rectangular tube 1 has two bendings, and rectangular tube I2 is parallel with rectangular tube III4 and pass through rectangular tube II3 connection, and rectangular tube I2, rectangular tube II3 and rectangular tube III4 are to same direction bending extension and in same plane.
The utility model adopts bending technique that whole rectangular tube 1 bent to structure as shown in Figure 1 through two bendings, this structure longeron is that rectangular tube of single-piece 1 forms through bending, not welding, thereby avoided weld defect, and in the bending process, be improved owing to flow harden effect bending part intensity.
