Abstract
The invention discloses a motorcycle head tube and connection box installing structure for a motorcycle. A connection box (4) is arranged at the rear side of a motorcycle head tube (1). The connection box (4) consists of left and right symmetrical reinforcement plates (4a). The front end of the connection box (4) is open and the rest of ends of the connection box (4) are closed. The front end of the connection box (4) is welded with the motorcycle head tube (1). The top of the rear end of the connection box (4) is welded with the front end of a main pipe (3). The lower end of the rear end face of the connection box (4) is provided with an opening. The upper end of a front inclined pipe (2) extends into the connection box (4) through the opening. The front inclined pipe (2) is fixed together with the connection box (4) through a welding mode. The upper end of the front inclined pipe (2) is welded on the motorcycle head pipe (1). When the connection strength among the motorcycle head pipe, the front inclined pipe and the main pipe is ensured, the motorcycle head tube and connection box installing structure for the motorcycle is easy to process and manufacture and has high production efficiency, the production cost of the finished motorcycle is effectively reduced, and the motorcycle head tube and connection box installing structure for the motorcycle is easy to improve and has low improvement cost.
Description
Technical field
The invention belongs to technical field of motorcycles, specifically, the particularly head tube connecting box mounting structure of motor bike.
Background technology
Head tube is positioned at frame of motorcycle foremost, is mainly used in to wear the direction post, and is rotatably connected with the direction post.At present, head tube generally welds with the preceding inclined tube and the left and right person in charge of vehicle frame through three brace panels mutually.In three brace panels, wherein one is " U " shape, and two is " L " shape in addition, and three brace panels need be made three secondary moulds, and die cost is high, can increase the productive costs of Finished Motorcycle of motorcycle.In addition, " U " shape brace panel opening end edge overlaps on preceding inclined tube, and fixing through welding; The long edge overlap joint of " L " shape brace panel is on preceding inclined tube, and is also fixing through welding.Weld seam is long between " U " shape brace panel and the preceding inclined tube and between " L " shape brace panel and the preceding inclined tube, can cause the waste of solder wire material, also can increase the productive costs of Finished Motorcycle of motorcycle.
Summary of the invention
Technical matters to be solved by this invention is to provide the motorcycle head tube connecting box that a kind of processing and fabricating is easy, productive costs is low mounting structure.
Technical scheme of the present invention is following: a kind of motorcycle head tube connecting box mounting structure; Comprise head tube (1), preceding inclined tube (2), be responsible for (3) and connecting box (4); Rear side at said head tube (1) is provided with connecting box (4); This connecting box (4) by about two symmetrically arranged brace panels (4a) form, these two brace panels (4a) connect, and are fixing through welding between two brace panels (4a); Said connecting box (4) front end is uncovered, and all the other ends are closed, the uncovered pipe shaft sealing of this connecting box (4) front end by head tube (1), and the front end of connecting box (4) welds with head tube (1) mutually; The top of said connecting box (4) rear end and the welding of the person in charge's (3) front end; The lower end of connecting box (4) aft end face is provided with opening; The upper end of inclined tube (2) is stretched in the connecting box (4) through this opening before said; Fixing between preceding inclined tube (2) and the connecting box (4) through welding, and the upper end of preceding inclined tube (2) is welded on the head tube (1).
Adopt above technical scheme, through the connecting box welding, this connecting box adopts box structure that front end is uncovered, all the other ends are closed between head tube, preceding inclined tube and the person in charge three, and intensity is reliable, can not deform or damage.Connecting box by about two symmetrically arranged brace panels form, only need a width of cloth mould to get final product, not only practiced thrift die cost greatly, and processing and fabricating is easy, production efficiency is high, can effectively reduce the productive costs of Finished Motorcycle of motorcycle.
Said brace panel (4a) is through the plate stamping moulding, is provided with " T " shape reinforced rib (4b) in the central region of brace panel (4a).Because the central region of brace panel is bigger, therefore set up " T " shape reinforced rib, play a part to gain in strength.
The position of inclined tube (2) has two cylindrical voids (4c) up and down before the correspondence on the plate face of said brace panel (4a), and the direction of tilt of length direction of this cylindrical void (4c) and preceding inclined tube (2) in the same way.Carry out plug welding through two cylindrical voids, can guarantee the weld strength between brace panel and the preceding inclined tube, effectively avoided the solder wire material waste, also can play the effect that reduces production costs.
Beneficial effect: in the Joint strenght, processing and fabricating is easy, production efficiency is high, effectively reduces the productive costs of Finished Motorcycle of motorcycle between assurance head tube, preceding inclined tube and person in charge three in the present invention, and transformation is easy, improvement cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the block diagram of connecting box among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in Figure 2, the present invention is made up of head tube 1, preceding inclined tube 2, the person in charge 3 and connecting box 4.Wherein, preceding inclined tube 2 and be responsible for 3 all be positioned at head tube 1 rear side, preceding inclined tube 2 is in the place ahead of being responsible for 3, the in the past high back low dip settings of preceding inclined tube 2.About the said person in charge 3 is divided into two, be responsible for 3 for these two and be and be symmetrically arranged.Rear side at said head tube 1 is provided with connecting box 4, the box like structure that this connecting box 4 is that front end is uncovered, all the other ends are closed, from the left side or the right side see, be approximately trapezoidal.The uncovered of connecting box 4 front ends is angle, this uncovered pipe shaft sealing by head tube 1, and the front end of connecting box 4 welds with the pipe shaft of head tube 1 mutually.The top of connecting box 4 rear ends with about two be responsible for 3 front end welding; Lower end at connecting box 4 aft end faces is provided with opening; The shape size of this opening adapts with preceding inclined tube 2, and the upper end of preceding inclined tube 2 is stretched in the connecting box 4 through this opening, and the upper end of preceding inclined tube 2 is welded on the head tube 1.
From Fig. 1, Fig. 2, can know; Connecting box 4 by about two symmetrically arranged brace panel 4a form; Brace panel 4a is through the plate stamping moulding; Central region at brace panel 4a is formed with " T " shape reinforced rib 4b through punching press, and reinforced rib 4b also can adopt other shape that is fit to, as long as can strengthen the intensity of brace panel 4b.About two brace panel 4a connect, fixing between two brace panel 4a through welding.The position of inclined tube 2 has two cylindrical void 4c up and down before the correspondence on the plate face of every brace panel 4a, and the length direction of this cylindrical void 4c and the direction of tilt of preceding inclined tube 2 are in the same way.Said cylindrical void 4c is as the auxiliary hole of plug welding, and is fixing through welding between inclined tube 2 and the brace panel 4a before making.
