Abstract
A shock absorber bottom valve compression system comprises a bottom body and a compression valve. A liquid passing piece spring, a liquid passing piece, the compression valve, a compression adjusting spring and a valve body are riveted together by utilizing a rivet sliding column and through a liquid passing press plate and a lower press plate. The shock absorber bottom valve compression system has the advantages that large compression damping force can be generated when a shock absorber works at a low speed, and the effects of buffering and shock absorption are achieved; the increment of the compression damping force generated when the shock absorber works at a high speed is extremely small, and aging of a rubber oil seal of the shock absorber and oil leakage under high temperature are avoided; and the bottom valve compression system is compact in structure, and space limitation of a suspension system is avoided.
Description
Technical field
The present invention relates to a kind of go-anywhere vehicle vibration damper bottom valve compression system.
Background technique
Automobile absorber is when work, and piston rod pumps with vehicle body, and vibration damper fluid is full of the piston cylinder cylinder body.When bar moved upward, the resetting valve system fluid of unifying produced recovery damping force; When bar moved downward, the compression valves system fluid of unifying produced compression damping power.The bottom valve compression system of motor vehicles for civilian use vibration damper adopts the valve block form, when promptly piston rod moves downward, produces compression damping power with fluid after the compression valve valve block resiliently deformable.Compression damping power and the positive correlation of piston rod movement speed, piston rod speed is generally 1m/s.Road conditions are poor, speed is fast and go-anywhere vehicle goes, and make the shock absorber piston rod operating rate be generally 3m/s.At this at a high speed down, if adopt valve block formula compression system, can produce huge compression damping power, can cause this moment: 1) huge compressive force rises the shock absorber fluid temperature, and high temperature causes aging, the leakage of oil of the rubber oil sea in the vibration damper, and vibration damper is scrapped.2) damping effect reduces, and riding comfort descends.Therefore to there be a cover to meet the vibration damper bottom valve compression system of go-anywhere vehicle suspension system attribute and installing space.That is: 1, piston rod (0.1m/s--0.17m/s) bottom valve compression system when low-speed motion produces big compression damping power.2, the piston rod damping force increment that (0.17m/s-3m/s) bottom valve compression system produces when high-speed motion is very little.3, the restriction in suspension space requires bottom valve compression system compact structure.
Summary of the invention
The invention provides a kind of when low speed compression damping power big, the go-anywhere vehicle vibration damper bottom valve compression system that compression damping power increment is little during high speed.
For achieving the above object, the technological scheme that the present invention takes is:
A kind of vibration damper bottom valve compression system comprises end body and compression valve, it is characterized in that utilizing the rivet traveller, through logical hydraulic plate and press table will lead to the liquid flat spring, lead to the liquid sheet, compression valve, compression adjustment spring, valve body be riveted together.
The first end platform compresses logical liquid flat spring on the above-described rivet traveller; The second end platform compresses logical hydraulic plate; Rivet traveller intermediate portion and compression valve endoporus Spielpassung; Rivet after rivet traveller lower end and the press table assembling.
The first end platform on the compression rivet traveller of above-described logical liquid flat spring upper end, the lower end compresses logical liquid sheet.
The above logical liquid sheet compresses through logical liquid flat spring and logical hydraulic plate; Logical liquid sheet center hole and rivet traveller Spielpassung.
Boss is forged in the above logical hydraulic plate upper-end surface, and compresses with logical liquid sheet; Following Transverse plane compresses through rivet traveller and valve body; The recovery through hole of forging, the through hole that compresses through hole, cooperates with the rivet traveller are arranged on the logical hydraulic plate.
Above-described compression valve upper-end surface compresses through compression adjustment spring and logical hydraulic plate lower end surface; Lower end surface and compression adjustment spring compression; The upper end is provided with a compression through hole; Center hole and rivet traveller Spielpassung.
The above compression adjustment spring upper end compresses with the compression valve lower end surface; Lower end and press table compress.
The above press table upper-end surface and compression adjustment spring compression; Edge, upper-end surface and valve body lower end compress; The riveting concora crush was tight after the rivet traveller passed the press table center hole.
The above valve body upper end anchor ring and logical hydraulic plate compress; Upper end platform and piston cylinder interference fit compress; Lower end platform and press table compress; Lower end surface and cylinder are stifled to be compressed.
The invention has the beneficial effects as follows: 1, vibration damper can produce bigger compression damping power when tick-over, plays the bumper and absorbing shock effect.2, the increment of the compression damping power that when high speed operation, produces of vibration damper is very little, avoids the aging leakage of oil of rubber oil sea under the vibration damper high temperature.3, bottom valve compression system compact structure has been avoided the suspension system spatial limitation.
