Abstract
The invention discloses a fuel tank structure of a motorcycle. The fuel tank structure of the motorcycle comprises an upper fuel tank shell and a lower fuel tank shell. A fuel filler is formed in one end of the upper fuel tank shell. The lower portion of the fuel filler is communicated with the lower fuel tank shell. A fuel deflector used for preventing fuel from overflowing is arranged between the fuel filler and the lower fuel tank shell. A fuel outlet nozzle is arranged on the lower portion of the lower fuel tank shell. The fuel outlet nozzle and the lower fuel tank shell are fixed in a welded mode. An overflowing pipeline clamp is further arranged on the upper fuel tank shell and is used for fixing an overflowing pipe. The overflowing pipeline clamp is located on one side of the fuel filler. The contact surface where the upper fuel tank shell and the lower fuel tank shell are connected is of a plane structure. The upper fuel tank shell and the lower fuel tank shell are fixed in an electric resistance welding mode. Four installation holes where a motorcycle frame is installed are formed in the four corners of the upper fuel tank shell respectively and comprise two round holes and two strip-shaped holes. The two round holes are arranged in a diagonal mode. The fuel tank structure of the motorcycle has the advantages of being simple in mold joint, more suitable for welding fixation, capable of relieving aging of a seal ring, easy to install, firm in installation, capable of saving materials and the like.
Description
Technical field
The present invention relates to a kind of motorcycle oil box structure, belong to motor bike and manufacture field.
Background technology
Existing motorcycle oil box structure be oil cap be directly threaded connection with fuel tank on, wash away in fuel tank in motorcycle driving process IFO intermediate fuel oil, be easy to contact with the rubber seal on fuel cover, that oxidizing reaction easily occurs is aging rapidly touching after fuel oil for rubber seal, sealing ring tightness after aging can reduce, and can have serious oil leakage phenomenon.And not prison welding between fuel tank upper-lower casing is solid, easily gas leakage, once and the fuel oil gushing in motorcycle driving or parking period run into naked light, be easy to make fuel tank blast on fire.Also there is the problem of the low and function singleness of degree of utilization in existing Oiltank structure in addition.
Summary of the invention
The present invention object be to provide a kind of motorcycle oil box structure, air tight, die joint is simple, is more suitable for being welded and fixed, and improves the degree of utilization of Oiltank structure and the rigidity of fuel tank.
Motorcycle oil box structure provided by the invention, comprises fuel tank upper shell and fuel tank lower house, and one end of its fuel tank upper shell is provided with oil filling port, and the bottom of oil filling port communicates with fuel tank lower house; Between described oil filling port and fuel tank lower house, be provided with the oil retainer washer for preventing that oil spill from going out; The below of described fuel tank lower house is provided with oil outlet, between oil outlet and fuel tank lower house by being welded and fixed; On described fuel tank upper shell, be also provided with the overflow pipe wire clamp for fixed weir pipe, overflow pipe wire clamp is positioned at a side of oil filling port; The contact surface connecting between described fuel tank upper shell and fuel tank lower house is planar structure; Between described fuel tank upper shell and fuel tank lower house, fix by electric resistance welding; Four jiaos of described fuel tank upper shell are provided with four for the mounting hole of vehicle frame is installed, and mounting hole comprises two circular holes and two bar holes, and two circular holes are diagonal line setting.
Optimize, above-mentioned motorcycle oil box structure, one end of its fuel tank upper shell is provided with the through hole for fuel sensor is installed, and the quantity of mounting hole is at least four.
Adopted above structure, the present invention has following beneficial effect:
In Oiltank structure of the present invention, fuel tank upper shell and fuel tank lower house are connected as a single entity by roll welding, and air tight, die joint is simple, are more suitable for being welded and fixed; Fuel tank upper shell is provided with fuel oil inductor mounting structure, the upper oil retainer washer of welding, in Vehicle Driving Cycle, avoids fuel oil to wash away to fuel lid rubber seal, accelerates the aging of seal ring; The clamping position of determining overflow pipe of overflow line; The vehicle frame mounting hole of design is by two round orifices orientations, and bar hole makes installation more easily more firm; Save material, simplified forming process, practical, easy for installation.
Accompanying drawing explanation
In order to be illustrated more clearly in the present invention, below will be to by reference to the accompanying drawings embodiment being briefly described.
Fig. 1 is the schematic diagram of motorcycle oil box structure of the present invention;
Fig. 2 be Fig. 1 birds-eye view.
