Background technology
Automobile suspension system produces vibrations owing to flexible member is hit, for improving the ride comfort of running car, in suspension, is installed in parallel amortisseur with flexible member. Concussion when amortisseur rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface. Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring self also has reciprocating motion, and amortisseur is just used to suppress this spring to jump. If amortisseur is too soft, vehicle body will vertical bounce, and amortisseur can bring about too big resistance too firmly, hinders spring normal operation, and the type that therefore amortisseur is selected is just extremely important. Now current, automobile suspension system adopt amortisseur be mostly hydraulic damper, when its operation principle is to shake when between vehicle frame (or vehicle body) and vehicle bridge and relative motion occur, piston in amortisseur moves up and down, and the fluid in snubber cavity just flows into another intracavity from a chamber through different holes repeatedly. Vibrations are formed damping force by now friction between hole wall and fluid and the intermolecular internal friction of fluid, make thump energy be converted into fluid heat energy, then are dispersed in air by absorber. Although this amortisseur uses commonplace, but owing to amortisseur and flexible member carry the task of buffer and damping, damping force is excessive, suspension flexibility will be made to degenerate, amortisseur connector is even made to damage, thus amortisseur to be adjusted to the degree matched with flexible member and can be only achieved optimum efficiency, but current amortisseur is difficult to mostly.

The technical solution of the utility model: a kind of shock absorber structure for automobile, it is characterised in that include working cylinder, is provided with oil storage cylinder in described working cylinder, forms shoe cream room, be provided with oil-out in oil storage cylinder rear end between working cylinder and oil storage cylinder;Piston rod is installed in oil storage cylinder, in the rear end of piston rod, piston is installed, described piston rear end is provided with mounting groove, piston rod connects with the positioning screw parent phase being located in mounting groove after piston, described location nut is cased with restore valve body, it is cased with base in the end, rear end of piston rod, between valve body and base, tension spring is installed restoring; In the rear end of oil storage cylinder, valve mechanism is installed, described valve mechanism includes the compression valve shaft being fixed on working cylinder inwall, described compression valve shaft is the I-shaped structure of horizontally set, compression valve shaft is cased with compression valve seat, being provided with compression valve block between the termination, rear end of compression valve seat and compression valve shaft, described compression valve block is arranged on oil-out place and is closed by oil-out; It is cased with fairlead in the front end of piston rod, described fairlead is connected to the front end of oil storage cylinder and is closed by shoe cream room, the piston rod of fairlead front end is also cased with oil sealing, between fairlead and oil sealing, is provided with oil seal spring, between oil sealing and working cylinder front inner wall, is provided with oil sheet.
Optimally, described piston rod is additionally provided with spring base, is glued with logical liquid valve block in the front end of piston, between spring base and logical liquid valve block, is provided with flowing valve spring. Piston impact force can be formed buffering by installing flowing valve spring, it is to avoid cause hard collision.
Optimally, it is glued with compensation valve block in the front end of described compression valve seat, between the termination, front end of described compensation valve block and compression valve shaft, is provided with counterbalance spring. Secondary motion can being formed when piston slap compresses valve shaft by installing compensation valve block and counterbalance spring, thus reaching the purpose of secondary shock-absorbing, improve damping performance.
Optimally, it is additionally provided with a locating ring at the middle part of piston rod, in the front end of locating ring, cushion pad is installed. Piston rod and fairlead can be protected by equipment cushion pad, reduce directly collision, protect equipment.
Relative to prior art, this utility model has the advantages that
1, improve the stability of amortisseur: shock absorber structure of the present utility model is based on vehicle performance, by improving amortisseur internal structure, well can mate with vehicle-mounted flexible member, thus while obtaining better damping effect, moreover it is possible to there is good stability.
2, reliability is better, and fault rate is relatively low, decreases the cost of maintenance, extends service life.
3, install simple, convenient.
