The requirement of modern people to vehicle running smoothness and riding comfort is more and more higher, so in the design of automobile, in suspension, is installed in parallel vibration damper attenuation vibration with elastic element, improves vehicle run smoothness and control stability.
When automotive wheel rolls on projection or rolls out pit, wheel shifts near vehicle frame (vehicle body), and vibration damper by compression, is compression stroke; Damper linking member moves down; Piston rod leads resetting valve system to move downward, and cavity volume below connecting rod reduces, and oil pressure raises, and in above the flow side piston that a part of fluid is flowed into by resetting valve system flowing valve, epicoele A3 carries out fluid and supplements.Because epicoele to be accounted for a part by connecting rod, the volume increased in epicoele is less than the volume that cavity of resorption reduces, therefore some fluid pushes compression valves system open, and the compressed side oil storage cylinder A1 flowing into compression valves system produces compression damping power.These valves realize the damping force to suspension compresses motion to the throttling of fluid.
When automotive wheel is rolled off projection or rolls into pit, the relative vehicle body of wheel is removed, vibration damper Tensile, is extension stroke; Now damper piston moves up; Restore stroke, piston rod leads resetting valve system to move upward, and vibration damper inner carrier epicoele A3 oil pressure raises, and flowing valve is closed; A part of fluid in epicoele produces recovery damping force by cavity of resorption A2 in the recovery side inflow of resetting valve system.Equally, due to the existence of connecting rod, the fluid come from epicoele stream is not enough to be full of the volume that cavity of resorption increases, and produce certain degree of vacuum in cavity of resorption, a part of fluid at this moment in oil storage cylinder carrys out supplementary fluid by cavity of resorption in the compensation side inflow A2 of compression valves system.Now, the throttling action of these valves achieves the damping force to suspension stretching exercise.
Whether whether the performance of vibration damper reaches designing requirement, mainly met design requirement by the mechanical property of vibration damper and determine.
The valve system rigidity of vibration damper is mainly determined by structural design, and shock absorber valve system comprises resetting valve system, compression valves system; Resetting valve system is divided into recovery side and flow side, and compression valves system is divided into compressed side and compensates side; The resetting valve system of shock absorber valve system, compression valves system comprise valve body and damping fin component respectively; The damping fin component that resetting valve system flow side and compression valves system compensate side comprises valve block, adjustment packing ring, spring sheet, packing ring respectively; Valve block, adjustment packing ring, spring sheet, packing ring are arranged on fastening piece successively, and valve block coordinates with valve body contact, is fastenedly connected by fastening piece and valve body.
As shown in Figure 3, Figure 4: the spring sheet that existing Rebuilt valve of shock absorber system flow side and compression valves system compensate side is three straight latch spring sheets; Because the tip diameter of piston rod is comparatively large, the size design space of the three-jaw spring sheet of resetting valve system is very narrow, and the three-jaw spring plate rigidity of flow side is very weak.There is vibration damper internal characteristic latent defect, correspondingly show as the idle running sex distortion of external characteristics indicator diagram; Due to valve system rigidity Design limitation, still have certain probability to occur idle running, especially when dither, former valve system leads to liquid valve block in dither process, runs shakiness, close and also tremble not in time, the existence of idle running sex distortion has a strong impact on smoothness and the control stability of vehicle.Impact travelling comfort by bus; Affect the vibration damping usefulness of vibration damper or the workmanship with suspension matching system damping.

Usual idle running sex distortion may appear at the starting stage of shock absorbers compression stroke, or the starting stage of absorber stroke; Generally the idle running sex distortion of vibration damper has more the starting stage of present compression stroke.
Although the compensation side of the flow side of resetting valve system and compression valves system does not produce corresponding compression damping power and recovery damping force, the size of three straight latch spring sheet rigidity directly affects the overall performance of valve system, three straight latch spring sheet rigidity linear change; In the adjustment of valve system, the change of rigidity is very quick, causes three-jaw spring sheet and circulation valve block or compensate the difficulty of matching of valve block very large.Especially, in vibration at high speed situation, the process that recovery stroke and compression stroke are changed mutually, the valve system rigidity of flow side and compressed side directly affects the travelling comfort of automobile driving.
In addition due to size and the reciprocating work characteristics of high strength of three-jaw spring sheet, the situation that three-jaw spring sheet arm of force legs break is split often is there is in endurance test, in production assembly process, three-jaw spring sheet arm of force leg easily sandwiches in circulation valve block or recuperation valve sheet hole slot, causes waste product.
