Abstract

Disclosed is a motor tricycle front shock absorber with high bearing ability and impact resistance. A thick and long steel sleeve is arranged at the upper part of a shock absorber, and the steel sleeve is accounted 4/5 length of the shock absorber. The lower end of an expansion pipe is directly connected with a front wheel axle, and the upper end of the expansion pipe is sheathed with an iron ring. A pressing spring is supported by the iron ring to move in the steel sleeve, and the lower end of the steel sleeve is provided with a steel ring and an oil seal. A buffering spring is arranged between the steel ring and the iron ring. The grinding portion of the shock absorber can be lubricated by the engine oil or the butter. This shock absorber has simple structure and strong practicability.

Description

The motor-tricycle bumper

Technical field

The utility model relates to front damper of motorcycle, is specifically related to front vibration absorber of motor tricycle.

Technical background

Motor-tricycle is the vehicle that grow up on the two-wheeled motorcycle basis, and therefore, motor-tricycle has adopted the many accessories on the two-wheeled motorcycle, but because motor-tricycle is a kind of transportation means of manned loading, its delivery power and usage degree substantially exceed two-wheeled motorcycle, and the front shock absorber of two-wheeled motorcycle is by tube at the bottom of the aluminium, draw-in bar core pipe, inner spring is formed, small and exquisite very thin, be used on the motor-tricycle, service life is short, leakage of oil is quite serious, and the outward appearance utmost point does not match.

A kind of mechanical shock absorption is arranged now, is to be made of several supports and one group of spring, and bearing capacity is stronger, but because its joint is many, complex structure, easy sideslip during use is sent out pendulum.

This motorcycle vibration absorber of the present utility model, the shortcoming of several bumpers more than having overcome, it is durable, and bearing capacity is strong, good damping effect, outward appearance magnificence, style are mated with motor-tricycle very much.

The technical solution of the utility model is, thick long steel pipe sleeve accounts for bumper overwhelming majority volume from top to bottom, following exposed portions serve telescopic pipe links to each other with wheel shaft, stage clip is housed, stage clip backing plate, slip iron ring and fixed steelring, oil sealing, fastening wire ring etc. in the sleeve, the telescopic pipe front end sleeve an iron ring, slide in sleeve with telescopic pipe, telescopic pipe slides in fixed steelring, places a circle recoil spring between two iron rings.

The beneficial effects of the utility model are: this damping product are suitable for the three-wheel vehicle of various spark ignition engines and diesel engine, and bearing capacity anti-impact pressure is held by force, and is simple in structure, and good damping effect is easily produced, and cost is low.

Below in conjunction with description of drawings:

Figure (1) is the elevation profile constructional drawing of utility model embodiment, among the figure, sleeve (1), telescopic pipe (2), stage clip (3), recoil spring (4), slip iron ring (5), fixed steelring (6), oil sealing (7), firm wire ring (8), spring backing plate (10), spring sleeve column (9), front-wheel axis hole (11).

The specific embodiment:

Figure (1) illustrated embodiment: with placement of steel pipe sleeve (1) lower end inwall processing, the step of steel ring (6), oil sealing (7), wire ring (8), telescopic pipe front end be next step dress iron ring (5) also.For reducing the long distortion of stage clip (3), can in sleeve (1), settle a backing plate (9), stage clip (3) to be enclosed within than small end on the sleeve column (5) of telescopic pipe (a 2) front end, successively recoil spring (4), steel ring (6), oil sealing (7), wire ring (8) are enclosed within then and put into sleeve (1) the inside on the telescopic pipe (2) together, screw wire ring fastening (8), sleeve column (9) and sleeve (1) top one filler port is arranged, add lubricating oil, also shouldn't filler port, without machine oil, between iron ring (5) and steel ring (6), add butter.Be contained on three-wheel vehicle direction post and the set square and can use complete a pair of damping is installed.

Claims

1, a kind of three-wheel vehicle front shock absorber: stage clip, slip iron ring, fixed steelring, recoil spring, oil sealing and part telescopic pipe are housed in steel bushing, and sleeve links to each other with the direction post, and telescopic pipe links to each other with wheel shaft.

2 bumpers according to claim 1, it is characterized in that: steel bushing accounts for 4/5ths of bumper total length on bumper top, directly press partially the telescopic pipe lower end, if the hole is connected with wheel shaft, rotating cast iron ring of telescopic pipe upper end cover, on sleeve lining, slide, on the sleeve column of compression spring sleeve on telescopic pipe, put in the sleeve and contact with backing plate, after steel ring was fixed on sleeve lower end peace oil sealing, fastening with wire ring, telescopic pipe slided in the steel ring of sleeve, one buffer spring is arranged between two iron rings, and can store butter.
