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 wearing steering column, and is rotatably connected with steering column.At present, head tube generally welds mutually by front inclined tube and the left and right supervisor of three brace panels with vehicle frame.In three brace panels, wherein one is " U " shape, and two is " L " shape in addition, and three brace panels need to be made three secondary moulds, and die cost is high, can increase the productive costs of Finished Motorcycle of motorcycle.In addition, the edge of " U " shape brace panel open end is overlapped on the front inclined tube, and by being welded and fixed; The long edge of " L " shape brace panel is overlapped on the front inclined tube, also by being welded and fixed.Weld seam is long between " U " shape brace panel and the front inclined tube and between " L " shape brace panel and the front 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 as follows: a kind of motorcycle head tube connecting box mounting structure, comprise head tube (1), front inclined tube (2), supervisor (3) and connecting box (4), rear side at described 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, between two brace panels (4a) by being welded and fixed; Described connecting box (4) front end is uncovered, and all the other ends are closed, the uncovered pipe shaft sealing by head tube (1) of this connecting box (4) front end, and the front end of connecting box (4) welds mutually with head tube (1); The top of described connecting box (4) rear end and the welding of supervisor's (3) front end, the lower end of connecting box (4) aft end face is provided with opening, the upper end of described front inclined tube (2) is stretched in the connecting box (4) by this opening, by being welded and fixed, and the upper end of front inclined tube (2) is welded on the head tube (1) between front inclined tube (2) and the connecting box (4).
Adopt above technical scheme, by the connecting box welding, this connecting box employing front end is uncovered, the box structure of all the other end closures between head tube, front inclined tube and the supervisor 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 greatly saved die cost, and processing and fabricating is easy, production efficiency is high, can effectively reduce the productive costs of Finished Motorcycle of motorcycle.
Described brace panel (4a) is by the plate stamping moulding, is provided with "T"-shaped reinforced rib (4b) in the central region of brace panel (4a).Because the central region of brace panel is larger, therefore set up "T"-shaped reinforced rib, play a part to gain in strength.
The position of inclined tube (2) has up and down two cylindrical voids (4c) before corresponding on the plate face of described brace panel (4a), and the direction of tilt of the length direction of this cylindrical void (4c) and front inclined tube (2) in the same way.Carry out plug welding by two cylindrical voids, can guarantee the weld strength between brace panel and the front 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, front inclined tube and supervisor three in the present invention, and transformation is easy, improvement cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the block diagram of connecting box among the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention is made of head tube 1, front inclined tube 2, supervisor 3 and connecting box 4.Wherein, front inclined tube 2 and be responsible for 3 rear sides that all are positioned at head tube 1, front inclined tube 2 be in the place ahead of supervisor 3, low dip settings after front inclined tube 2 was in the past high.About described supervisor 3 is divided into two, these two supervisors 3 are and are symmetrically arranged.Rear side at described head tube 1 is provided with connecting box 4, and this connecting box 4 is that front end is uncovered, the box like structure of all the other end closures, from the left side or the right side, is approximately trapezoidal.The uncovered of connecting box 4 front ends is angle, this uncovered pipe shaft sealing by head tube 1, and the pipe shaft of the front end of connecting box 4 and head tube 1 welds mutually.The top of connecting box 4 rear ends with about the welding of two supervisor's front ends of 3, lower end at connecting box 4 aft end faces is provided with opening, the shape size of this opening and front inclined tube 2 adapt, and the upper end of front inclined tube 2 is stretched in the connecting box 4 by this opening, and the upper end of front inclined tube 2 is welded on the head tube 1.
From Fig. 1, Fig. 2 as can be known, connecting box 4 by about two symmetrically arranged brace panel 4a form, brace panel 4a is by the plate stamping moulding, central region at brace panel 4a is formed with "T"-shaped reinforced rib 4b by punching press, 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, between two brace panel 4a by being welded and fixed.The position of inclined tube 2 has up and down two cylindrical void 4c before corresponding on the plate face of every brace panel 4a, and the length direction of this cylindrical void 4c and the direction of tilt of front inclined tube 2 are in the same way.Described cylindrical void 4c makes between front inclined tube 2 and the brace panel 4a by being welded and fixed as the auxiliary hole of plug welding.
