Abstract
The present invention relates to a damping device with two guides and lubrication for automobiles, which has the technical scheme that the damping device comprises an oil storage cylinder, wherein a working oil cylinder is arranged in the oil storage cylinder; the bottom of the oil storage cylinder is connected with the bottom of the working oil cylinder through a bottom valve; a piston device is arranged in the working oil cylinder; a first guide sleeve and a second guide sleeve are arranged on the upper part of the working oil cylinder; the two guide sleeve are sheathed on a piston rod through guide bearings; and an oil seal is arranged at the tops of the two guide sleeves. The present invention is characterized in that guide tubes are arranged on connecting rod shafts at both ends of a piston; interrupting spring brackets are arranged at both ends of the guide tubes; interrupting springs are reversely arranged on the interrupting spring brackets; an oil storage slot is arranged at the top of the first guide sleeve; a first guide sleeve oil return hole which penetrates through the upper side and the lower side of the first guide sleeve is arranged on the first guide sleeve; an annular slot is arranged at the top of the second guide sleeve; a second guide sleeve oil return hole is arranged on the inner wall of the annular slot; and the first guide sleeve oil return hole is communicated with the second guide sleeve oil return hole.
Description
Technical field
The invention belongs to the vehicle shock absorber field, especially two guiding add lubricated vehicle shock absorber.
Background technique
At present, vehicle shock absorber has multiple structure, mostly is welding mechanism greatly, and the problem of existence is once to use, easily wearing and tearing and leakage of oil.In order to address these problems, in being 99122594.5 patent, the patent No. introduced a kind of vehicle shock absorber, and this vibration damper can address the above problem, and has use value preferably.But these patent vibration damper two guide sleeve greasy properties are bad, are provided with the passage that runs through oil storage tank and lower surface on first guide sleeve, and the first guide sleeve oil reserve is few, so the side-friction force of piston rod is big, still has the fast problem of parts wear.
Summary of the invention
The purpose of this invention is to provide a kind of two guiding that can reduce wearing and tearing, enhancing effectiveness in vibration suppression and add lubricated vehicle shock absorber.
Technological scheme of the present invention is: two guiding add lubricated vehicle shock absorber, comprise an oil storage cylinder, an operating cylinder is set in oil storage cylinder inside, the bottom of oil storage cylinder is connected by bottom valve with the bottom of operating cylinder, in operating cylinder, be provided with piston apparatus, on the top of operating cylinder first guide sleeve is set, on first guide sleeve, be provided with second guide sleeve, two guide sleeve upper and lower end face butt joints, two guide sleeves are socketed on the piston rod by guide bearing, top at second guide sleeve is provided with oil sealing, it is characterized in that on the pitman shaft at piston two ends, being respectively arranged with conduit, two end face settings that link to each other with piston at conduit resting type spring support that dams, on the resting type spring support that dams, oppositely be provided with the spring that dams, top at first guide sleeve is provided with oil storage tank, first guide sleeve is provided with the first guide sleeve spill port that runs through the first guide sleeve upper and lower surface, top at second guide sleeve is provided with annular groove, the annular groove inwall is provided with the second guide sleeve spill port, the first guide sleeve spill port and the second guide sleeve spill port are communicated with, and the lower end of the first guide sleeve spill port is communicated with oil storage cylinder.
The top of the second guide sleeve spill port is arranged on the annular groove sidewall.
The oil storage tank that the top of first guide sleeve is provided with is annular oil storage tank.
Be connected on the piston rod by composite bearing at first guide sleeve and second guide sleeve.
It is gentle to the glue ring that the piston rod of the first guide sleeve lower end is provided with spacing iron hoop.
The lower end of described oil storage cylinder is provided with link.
Effect of the present invention is: the pitman shaft at piston two ends is provided with conduit, and two end face settings that link to each other with piston at conduit resting type spring support that dams oppositely is provided with the spring that dams on the resting type spring support that dams.The piston of the vibration damper rate-sensitive of damming, effectiveness in vibration suppression obviously improves, and reduces the frock error in processing.Top at first guide sleeve is provided with oil storage tank, first guide sleeve is provided with the first guide sleeve spill port that runs through the first guide sleeve upper and lower surface, the first guide sleeve spill port does not communicate with the oil storage tank of first guide sleeve, make lubricant oil in the first guide sleeve oil storage tank second guide sleeve of increasing supply, improve the greasy property of vibration damper.Top at second guide sleeve is provided with annular groove, and the annular groove inwall is provided with the second guide sleeve spill port, and the first guide sleeve spill port and the second guide sleeve spill port are communicated with, and the lower end of the first guide sleeve spill port is communicated with oil storage cylinder.Can make the oil lubrication second guide sleeve composite bearing in the first guide sleeve oil storage tank, therefore can reduce side-friction force, coaxality is good, increases the service life.
The present invention is described further below in conjunction with drawings and Examples.
