Abstract
The present invention relates to a front shock absorber for three-wheeled motorcycle and comprises a shock absorber tube (2), a shock absorber column (13) and a joint (1). The shock absorber column is arranged in the shock absorber tube and is connected to the joint of the shock absorber tube through a guide rod (3) and the shock absorber tube (2) is molded by stretching high-precision cold-drawn steel tube or cold-drawn steel tube, with large carrying capacity, high impact resistance and reduction of manufacturing cost; a guide sleeve (4) on the upper end of the guide rod and a guide sleeve (9) of the internal cavity of an expanding body on the upper end of the shock absorber tube are powder metallurgy sleeve or engineering plastic sleeve, with good wear resistance and long service life; the lower end of the shock absorber column is provided with one or more sections of composite sleeves (6), and the composite sleeve is copper-based or oil-free bearing or powder metallurgy sleeve, avoiding direction friction between the shock absorber column and the shock absorber tube; the two guide sleeves and the composite sleeve support the shock absorber column commonly so that the shock absorber column can do linear reciprocating motion, with the function of guidance and protection and greatly reduction of friction coefficient. The shock absorber has the advantages of low cost, wear-resistant, low noise and good corrosion resistance.
Description
Technical field
The present invention relates to a kind of bumper, specifically is a kind of front shock absorber that is used on the motor-tricycle.
Background technology
Be used for the front shock absorber on the motor-tricycle at present, the joint on its damping cylinder and the damping cylinder, splash apron bracket etc. are for aluminium is cast into one, and cost height, intensity are low, processed complex, service life are short.
Summary of the invention
Damping cylinder adopts the high drawback of aluminum cost in the prior art in order to overcome, the purpose of this invention is to provide a kind of rational in infrastructure, simple, low, long service life of cost of processing, damping cylinder adopts the front vibration absorber of motor tricycle of high-precision cold drawing steel pipe drawing and forming.
The technical solution used in the present invention is: a kind of front vibration absorber of motor tricycle comprises damping cylinder, shock structure, joint, and described shock structure is installed in the damping cylinder, and shock structure is by high-precision cold drawing steel pipe or cold drawing steel pipe is stretched forms; Shock structure is connected in through pilot bar on the joint of damping cylinder, and the pilot bar upper end is equipped with orienting sleeve, damping spring, oil ring, and shock structure is built-in with damping spring; Damping cylinder upper end expansion body inner chamber is equipped with orienting sleeve, oil sealing, jump ring, cover of dust; Be equipped with compound cover on the positioning groove of shock structure lower end periphery, compound cover is the compound cover of copper base or oilless metal or powder metallurgy sleeve.Shock structure is supported jointly by two orienting sleeves and a compound cover, does straight reciprocating motion in damping cylinder.
Further, the orienting sleeve of orienting sleeve on the described pilot bar and damping cylinder upper end expansion body inner chamber is powder metallurgy sleeve or engineering plastics cover; Described joint is steel casting or press forging, is welded in the damping cylinder bottom; Described splash apron bracket is steel casting or press forging, is welded on the damping cylinder; Described compound putting is provided with expansion joint, is installed in the positioning groove on the shock structure; Described damping cylinder external diameter is φ 35～60mm, and barrel thickness is 2～3mm.
The damping cylinder of this front vibration absorber of motor tricycle adopts high-precision cold drawing steel pipe or cold drawing steel pipe drawing and forming, the tube inner wall smooth, and good toughness, load-carrying capacity is big, and strong shock resistance greatly reduces manufacturing cost; Orienting sleeve in the orienting sleeve of pilot bar upper end and the damping cylinder upper end expansion body all adopts powdered metallurgical material or engineering plastics to make, and resistance to abrasion is good, long service life; The compound cover of copper base or oilless metal or the powder metallurgy sleeve that install the shock structure lower end can be avoided the direct friction of shock structure and damping cylinder; Two orienting sleeves and a compound cover reduce shock structure friction force in the linear reciprocation process greatly, have wear-resisting, performance such as friction coefficient is little, noise is low, resistance to corrosion is good, moving equilibrium, guiding and protection.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among Fig. 1, joint 1, damping cylinder 2, pilot bar 3, orienting sleeve 4, damping spring 5, compound cover 6, oil ring 7, splash apron bracket 8, orienting sleeve 9, oil sealing 10, jump ring 11, cover of dust 12, shock structure 13, damping spring 14, bushing pipe 15, hold-down nut 16.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described.
As shown in Figure 1, damping cylinder 2 is by high-precision cold drawing steel pipe or cold drawing molding of cold drawing steel pipe, its bottom is welded with joint 1, joint 1 is for adopting the steel casting or the press forging of the accurate cast molding of paraffin, be welded with splash apron bracket 8 on the damping cylinder 2, splash apron bracket 8 is for adopting the steel casting or the press forging of the accurate cast molding of paraffin; Shock structure 13 is high-precision cold drawing steel pipe, the positioning groove of its lower end cylindrical is built-in with compound cover 6, and compound cover 6 is the compound cover of copper base or oilless metal or powder metallurgy sleeve, and compound putting is provided with an expansion joint, the convenient installation and replacing avoided damping cylinder 2 inwalls and shock structure 13 outer wall direct friction; Orienting sleeve 4 is fixedly installed in shock structure 13 bottom inner chambers, the combination of formation shock structure, the shock structure combination is inserted in the damping cylinder 2, and orienting sleeve 9, oil sealing 10 be placed in be pressed on the shock structure 13 in the damping cylinder 2 upper end expansion body, pack into jump ring 11 and compress cover of dust 12, orienting sleeve 4 is powder metallurgy sleeve or engineering plastics cover with orienting sleeve 9, and cost is low, wear-resisting, long service life; The pilot bar 3 that one end is equipped with damping spring 5 and oil ring 7 pack into damping cylinder 2 and shock structure 13 inner chambers place on the orienting sleeve 4 the damping spring 5 of one end, and the other end lock onto on the joint 1 through bolt by the damping cylinder inner chamber; With the assembling after assembly carry out air tight test, tightness test after, from the special-purpose anti-shock fluid of shock structure 13 injections suitable for reading, after the shock structure inner chamber is put into damping spring 14, bushing pipe 15, at shock structure 13 hold-down nutes 16 of tightening suitable for reading.
This bumper is installed on the preceding direction device of motor-tricycle, and after motor bike was hit, shock structure was done straight reciprocating motion along pilot bar in damping cylinder, play cushioning effect, two orienting sleeves and a compound cover be guide-localization both, can reduce friction again, prolongs the service life of bumper.
