Abstract

The utility model discloses a shock damper for motorcycles which is composed of a front and a back shock damper. The front shock damper is composed of a piston rod, a piston, a supporting internal sleeve, a compressed buffer pocket, a casing, a working cylinder, an oil cylinder, a dust prevention lip, and an oil seal. The back shock damper is composed of a buffer pocket, a connective sleeve suspending ear, a piston rod, a piston, a screw cap, one oil seal, a dust-proof cover, a compressed buffer spring, a throttle valve plate on the piston, a reset spring sheet, a supporting sleeve, one working cylinder, and one oil cylinder. The utility model is characterized in that the supporting sleeves of the front and back shock damper are made of a steel shell, a bearing material tin bronze, a bearing material babbit, a solid lubricant polytetrafluoroethylene or polyoxymethylene four layers. The dust prevention lip of the front shock damper increases a self-tightening spring. The working cylinder of the front shock damper is formed from a finish rolling tube by cool extrusion and processing. The throttle valve plate on the piston of the back shock damper is the reset of a conical helical spring. The utility model has the advantages of good sealing performance and good cushioning performance. The phenomena that oil seal and a dust prevention ring are cut owing to spraining the piston rod and the supporting sleeve can be avoided, and the resistance is adjustable.

Description

Shock damper for motorcycle

The utility model is the damping original paper that belongs to motor bike.

The front shock absorber of the bumper of existing motor bike is that piston has been defended piston and cutoff port, be enclosed within the supporting in piston defends, put the compression cushion collar in the supporting, the shell of bumper links to each other with supporting sleeve with dust protecting cap, the location jump ring links to each other with the location lining ring, oil sealing is fixed on the fluid mouth of dust protecting cap, and the self-tightening spring fixedly on the oil sealing, defend interior and contact with cover in the supporting by the buffer spring fixed piston; Rear shock absorber is to link to each other with coupling sleeve in the cushion collar, link to each other with hanger outward, piston is defended by nut and cushion rubber and is fixed on the hanger, between hanger and oil sealing, dust boot is arranged, the compression buffer spring is arranged between steady ring outside oil cylinder and the hanger, oil cylinder is by the oil sealing trim ring, oil tight skeleton, oil sealing prevents that the oil in the oil cylinder from flowing out, the self-tightening spring is clamped on piston with the oil sealing lip and defends, individual layer supporting condom piston and is defended and seal in-oil cylinder clutch release slave cylinder, and from the skeleton of steel, the piston that piston is defended has piston ring in the middle of oil sealing, the fixed restrictor valve block is arranged on piston, reseting spring leaf, spacing pad, between individual layer supporting sleeve and spacing pad the buffer spring of resetting is arranged, the self-tightening spring is tight with the lower end envelope of oil cylinder and work, links to each other with cushion collar then.The oil sealing of existing bumper itself has only main oil sealing lip together, poor reliability; Lost efficacy with regard to leakage of oil in case wear and tear or pushed away wound by mechanical admixture, one oil sealing directly directly brought in the face of the high pressure oil that vehicle forms when vibrating simultaneously, can not step-down, and oil sealing is not considered even part under the antifriction that the friction of motion bearing support pays, the wear-resistant bearing support operating mode.The surface roughness that piston is defended is too high; block bearing is controlled golden part structure with individual layer powder; carrying, antifriction, wear ability difference PV value are lower than the impact operating mode, and the PV of real work plants 30%, and it is unreliable to work; the roughness of surface height of endoporus; it is poor that effect extreme difference, powder are controlled the self-lubricating property of golden part structure, thereby kinematic pair, piston defended to protect mutually pulls that piston is defended and supporting sleeve; cause coarse piston to defend to cut oil sealing and dust ring causes leakage of oil, and can not regulate resistance.

The purpose of this utility model is to improve dust ring; The oil sealed reliability, durability reduces the roughness that piston is defended, make its to piston defend, supporting sleeve, oil sealing, Fang Quan, even part realize that protection is not hindered mutually mutually, thereby improve reliability.

The utility model is achieved in that the dustproof lip at the front shock absorber of existing motor bike adds the self-tightening spring, oil sealing adds the self-tightening spring again one, the composite material back plate is added on the composite material supporting sleeve, the location lining ring is clipped between brace panel and the composite material back plate, the composite material back plate is that nylon material is made, the composite material supporting sleeve is a box hat, the light copper of bearing material tin, the bearing material Babbitt matal, the four-layer structure of solid lubricant polytetrafluoroethylene or polyformaldehyde is formed, and the clutch release slave cylinder that processes through cold extruding with the finish rolling pipe is close to the inwall of bumper shell.

Rear shock absorber is that dustproof lip is provided with the sealing lip, change brace panel at the oil sealed skeleton, have the ring joint chute on steel disc slide plate on the piston and the piston and long through-hole replaces original fixed restrictor, original steel disc valve block is that non-adjustable belleville spring changes conical helical spring into and resets, and supporting sleeve is to use the composite material supporting sleeve; The composite material back plate is pressed on the supporting sleeve.

Effect of the present utility model is the close structure of envelope, dustproof reliable, it is oil tight to travel on various road conditions, good endurance, damping performance is good, can adapt to various good and abominable road conditions, the self-lubricating property of the composite structure of block bearing is good, the kinematic pair piston is defended can be played protection and do not pull that piston is defended and supporting sleeve; Therefore, also avoided piston to defend and cut, and can also play the adjusting drag effect by oil sealing and dust ring.
