Abstract

The utility model relates to a simple double support with a double-port lip oil sealing assembly. As the oil sealing is positioned on the middle position of a supporting cur-off sheet and a dustproof supporting sleeve, the oil sealing still lies in the protected working condition by the supporting of the both ends when the connecting rod lies in the radial load, and the oil sealing is not supported with the radial load. Simultaneously, the double-port lip oil sealing is protected by the supporting cur-off sheet and the dustproof supporting sleeve, and then is free from the abrasion caused by the impact of the high pressure oil of the working cylinder and the foreign mechanical sundries. When the shock absorber lies in the radial load, the utility model keeps the reliability and the durability of the oil sealing and supporting, and is suitable for the oil sealing supporting assembly of the McPherson suspension shock absorber with high radial load of the miniature automobiles, cars and passenger vehicles.

Description

Automobile dashpot radial high-loading support and oil seal device

The utility model belongs to radially top load of automobile absorber, oil tight double base oil sealing arrangement.

It is the hydraulic retarder of resisting medium with oil that well-known automobile absorber is one, in case bumper leakage of oil then the bumper that lost efficacy beyond doubt, solve bumper leakage of oil problem and become one technical barrier in the industry, car particularly, the Mai Feisenshi suspension damper that mid-get car is used, being in oil sealing that connecting rod bears the great bad working environments of radial weight usually still is in because of connecting rod list fulcrum hangs end and imposes great diametral load to oil sealing and make oil sealing distortion leakage of oil, or bring the dust mechanical admixture into and cause the wearing and tearing leakage of oil, make defective shock absorber, this problem greatly reduces the durability reliability of this Mai Feisenshi suspension damper.Developed the different Mai Feisenshi suspension damper of structure for solving the domestic and international specialized factory of this technical matters; but these producers only work hard on oil sealing improves; do not bear radial weight and overcome proofing dust and protecting from solving the elimination oil sealing; and work hard on the key problem of buffering exhaust, it is little therefore to produce effects.The utility model has adopted two fulcrum multifunctional axial bearing apparatus has been set in the seal casing; in the middle of these two multi-functional fulcrum rollers; be provided with the twoport lip chip oil sealing of size Xiao Bao; make oil sealing be in the technical matters of removal radial weight deformation failure; in addition since up and down fulcrum roller be in together on the gyro-rotor seal casing; therefore the high axial dimension of accuracy of positioning is little; rigidity is big; go up simultaneously and be provided with dust ring on the fulcrum roller; and thereby compound exhaust buffer gear has been protected connecting rod and oil sealing; be provided with backflash on the combined seal protection mechanism lower fulcrum bearing; therefore having bottled up oil sealing no longer bears by the impact of clutch release slave cylinder by the high pressure oil jet of orienting sleeve extrusion; oil sealing is worked under low pressure or normal pressure operating mode; operating mode transfers to well; thereby simultaneously two fulcrum rollers have improved the rigidity of connecting rod and the durability that cleanliness level has improved the Mai Feisenshi suspension damper, reliability.

The purpose of this utility model is to overcome bad working environments that prior art Mai Feisenshi bumper oil sealing is in top load radially, makes oil sealing be in off-load work in the double base axle; improve the rigidity and the cleanliness level of connecting rod; reduce the wearing and tearing of oil sealed mechanical admixture connecting rod is implemented protection; eliminating oil sealing is subjected in the clutch release slave cylinder impact of the high pressure jet that extrudes from guide pin bushing that oil sealing is in the good operating mode; thereby improve the reliability and the durability of Mai Feisenshi suspension damper, produce a kind of bumper of function admirable.

In order to realize above purpose, new-type structure design and combination technique that the utility model adopts on structure design are as follows:

1, the room is provided with the compound upper support cover of top vent pads and band dust ring under the cushion rubber of seal casing upper end; vent pads has overcome cushion rubber inflation problem and be pressed into dust impurity in dust ring upper support cover and oil sealing; thereby protected the reliability of this device; upper support is applied mechanically self-lubricating material and is made, thereby is middle oil sealing off-load, and oil sealing is not still carried in high radial load; protected oil sealing; improved the rigidity of connecting rod simultaneously, cleanliness level has been protected oil sealing.2; overlap next dead axle at upper support and be provided with book shape twoport lip chip oil sealing to gap location; oil sealing is by last lip; last self-tightening spring; brace panel; following lip; following self-tightening bullet is formed; oil sealing is fixed in the middle of the lower support by spacing ring; end face and last lower support keep appropriate gap; this oil sealing is subjected to supporting and protecting up and down; all the time be in the rigidity cleanliness level; work in the operating mode that shaped position degree precision is high on the good same single-revolution positioning unit; not bearing radial weight becomes one and changes whole independent assembly easy to assembly; be convenient to tissue in enormous quantities and produce and the merchandizing normalisation, the cushion rubber on upper support top was arranged above the while; the protection of vent pads dust ring, cleanliness level is good; the wearing and tearing of abrasive particle machinery foreign material have been reduced; be subjected to the supporting of lower support plate below and intercept protection, eliminate the high pressure jet that extrudes from clutch release slave cylinder and impact, make oil sealing be in the work of normal pressure operating mode.Twoport lip oil sealing has increased the leak free reliability simultaneously; 3, under oil sealing and nest, be provided with combined seal fender guard lower fulcrum bearing; bearing and oil sealing are in together on the gyro-rotor seal casing; increased the rigidity of installing and locating precision and device; the lower fulcrum bearing bore has the antifriction antiwear layer to improve the durability of device; lower fulcrum bearing and orienting sleeve keep on the certain interval circumference a plurality of back leakage grooves being set; intercept the high pressure jet that extrudes by clutch release slave cylinder to the oil sealed jet impact, improved the reliability and the durability of device.

According to above new-type structure design and combination technique and this device of constructing is the leakage of oil problem that can overcome the Mai Feisen suspension damper that car, mid-get car dispose fully; make oil sealing be in no radial weight; there are not mechanical impurity wearing and tearing; dust impurity is inflated and be pressed into to cushion rubber downwards on not having does not have in the good operating mode of high pressure jet fluid impact; thereby the durability and the reliability that make oil sealing work and improve bumper in the works fine environment of the insulation blocking of two fulcrum rollers, conventional bumper use this device will make durability and reliability reach 5 * 10 ⁶More than inferior.Satisfy durability and reliability requirement that high durable bumper proposes oil sealing.Become automobile absorber radially oil tight supporting of top load and oil sealing arrangement.
