Abstract

A motorcycle front shock absorber of the more piece combined typed bobbin base relates to a front shock absorber for motorcycles. According to the shortcomings of front shock absorbers assembled for motorcycles sold on the market that the bobbin base employed by the front shock absorber is a single integrity which has large configuration, large casting mold, high manufacturing cost and long periodic time, the bobbin base is simultaneously a blind hole and needs to manufacture an elongated deep hole which requires better equipment, expensive tools and more procedures in manufacturing, and the coarseness in the process of manufacturing can hardly achieve the technical requirement, which affects the absorbing effect with low intensity and bad safety and reliability, a motorcycle front shock absorber of the more piece combined typed bobbin base which has simple structure and is easy to manufacture, increase the safety and the intensity of the shock absorber is proposed. The employed technical proposal is that the other end of an upper connector (7) is connected with an annular tube (8), and the other end of the annular tube (8) is connected with a lower connector (13).

Description

The front damper of motorcycle of tube at the bottom of the more piece compound type

One. technical field

The utility model relates to the front shock absorber that motor bike is used, and especially adopts the front damper of motorcycle of tube at the bottom of the more piece compound type.

Two. background technology

In the market the end tube that adopts of the front shock absorber of the motor bike of selling assembling be single integral body, profile is big, casting mould is big, the processing charges height, cycle is long, and end while tube is blind hole and elongated deep hole working, requires to have good equipment, expensive cutter, multiple operation processing, roughness is difficult to reach technical requirements in the processing, influences shock absorber effect, size and form and position tolerance also are difficult to guarantee conformability, processing condemnation factor height; Intensity is low simultaneously, safe reliability is poor; The tube profile variation is few at the bottom of the integral type, color is single, can not finely satisfy the deficiencies such as needs of the many kinds in market, diversified development.

Three. summary of the invention

The purpose of this utility model provides a kind of simple in structure, and handling ease strengthens bumper intensity, the front damper of motorcycle of tube at the bottom of the more piece compound type of raising bumper safety.

The technical scheme that the purpose of this utility model adopted is, the front fork tube front end is connected with the end cap that has O-ring seals, the middle part cylindrical is with to have dust-proof seal ring adjacent with oil sealed top connection in a tubular form, middle device has damping spring, the damping spring other end of dress contacts with the outer registration arm end that has piston ring and buffering spring of pipe in the terminal pipe, the other end of registration arm contacts with the interior step of the pipe of lower adaptor in a tubular form, registration arm is terminal to be threaded with socket head cap screw, damping oil is arranged in the chamber, the other end of its top connection is connected with sleeve pipe, and the other end of sleeve pipe is connected with lower adaptor.

The utlity model has simple and compact for structurely, manufacture craft is easy, assembles easy to maintenancely, specious, unique, novel, strengthens bumper intensity, improves characteristics such as bumper safety.

Four. description of drawings

Further specify the utility model below in conjunction with accompanying drawing.

Accompanying drawing is the utility model sectional structure scheme drawing.

Among the figure: 1-end cap 2-O shape seal ring 3-damping spring 4-front fork tube 5-dust-proof seal ring 6-oil sealing 7-top connection 8-sleeve pipe 9-piston ring 10-recoil spring 11-registration arm 12-damping oil 13-lower adaptor 14-socket head cap screw

Five. the specific embodiment

As shown in drawings, front fork tube 4 front ends have end cap 1, the middle part cylindrical that has O-ring seals 2 and have dust-proof seal ring 5 adjacent with the top connection 7 of oil sealing 6, top connection 7 other ends are connected with sleeve pipe 8, sleeve pipe 8 other ends are connected with lower adaptor 13, registration arm 11 ends link to each other with socket head cap screw 14 screw threads, be placed with damping spring 3 in front fork tube 4 pipes, the other end of damping spring 3 contacts with registration arm 11 tops of band piston ring 9 and buffering spring 10, the other end of registration arm 11 contacts with interior step in the lower adaptor pipe 13, and damping oil 12 is arranged in the chamber.
