Description
Technical field
The present invention relates to vibration absorber, more particularly to shock absorber compression hydraulic buffer gear.
Background technology
In vehicle travel process, the piston rod of shock absorber moves up and down shock absorber, drives fluid to pass through piston valve and pressure
Contracting valve produces damping force, absorbs the vibrational energy of vehicle, ensure that the comfortableness for multiplying and driving.Due to work(of the shock absorber in vehicle
Can so that piston rod does straight reciprocating motion always relative to working cylinder.Therefore, just necessarily require when wheel bob,
Realized by shock absorber and cushioning restraint is carried out to the wheel bob limit.Shock absorber not only acts as vibration isolation effect, also reaches to car
The bounce limit of wheel carries out cushioning restraint function;But in excessive bumpy road, it is necessary to buffer by shock absorber outside or inside
Structure rocks upper jump with wheel to suppress vehicle body, it is ensured that the comfortableness and stability of running car.
When running into pitchpole, piston rod can be impacted directly to compression valve simultaneously, influence service life, therefore existing
Shock absorber in can buffer gear is set between piston rod and compression valve, conventional shock absorber internal damping mechanism, some are
Spring buffer, but with the increase of usage time, spring easily produces decay, and pooling feature declines, and brings noise, can not be very
Good solves the problems, such as that shock absorber service life is short.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of shock absorber to be buffered with compression hydraulic
Mechanism, service life length.
For achieving the above object, the technical solution adopted by the present invention is:A kind of shock absorber compression hydraulic buffer
Structure, including working cylinder and the piston rod being slidably arranged in working cylinder, are provided with sealing mechanism between piston rod top and working cylinder,
Underpart of the piston rod is provided with piston valve, and working cylinder lower end is provided with compression valve, and the cushion dashpot of upper end open, piston rod are provided with working cylinder
Lower end outside face is circumferentially with first annular lug boss along it, when first annular lug boss enters cushion dashpot, position in cushion dashpot
Part below first annular lug boss forms the first cushion chamber, cushion dashpot upper surface, working cylinder upper cylinder and piston rod
Between form the second cushion chamber, between cushion dashpot lateral wall, cushion dashpot bottom surface and working cylinder lower cylinders formed the 3rd cushion chamber,
The oil transportation hole of the second cushion chamber and the 3rd cushion chamber, first annular lug boss lateral surface and/or buffering are communicated with cushion dashpot
Cylinder upper inner face is communicated with the oil-returning structure of the first cushion chamber and the second cushion chamber.
When being only provided with oil-returning structure in first annular lug boss lateral surface, underpart of the piston rod lateral surface is circumferentially with along it
Second annular relief, the second annular relief is between piston valve and first annular lug boss, when the second annular relief
During into cushion dashpot, the second annular relief seals the opening of cushion dashpot upper end.
The piston-rod lower end is provided with the profile nut being connected through a screw thread with piston rod, first annular lug boss and second
Annular relief is arranged on profile nut.
The first annular lug boss is arc convex, and first annular lug boss lower end is concordant with profile nut lower end.
The cushion dashpot upper end is provided with turnup structure, and oil transportation hole is arranged on turnup structure.
The oil transportation hole is circumferentially uniformly distributed along cushion dashpot.
The working cylinder is two sections formula structure, and the epimere and hypomere of working cylinder are respectively sleeved at the flange knot of cushion dashpot
A complete working cylinder is formed on structure.
The epimere and hypomere of the working cylinder are interference fitted with the turnup structure of cushion dashpot.
The cushion dashpot is close to working cylinder bottom.
The oil-returning structure is oil-recovery tank.
The present invention is simple in construction, and manufacturing cost is low, and when prevailing roadway travels, piston rod moves back and forth above cushion dashpot,
Its resistance is smaller, and now the suspension of vehicle is softer, and passenger inside the vehicle's seating is pleasant, and when running into pitchpole, piston rod is quick
Move downward, profile nut enters in cushion dashpot, the resistance that the hydraulic oil in cushion dashpot is moved downward by compression increase piston rod
Power, reduce impact of the piston rod to piston valve and compression valve, increase the service life of the present apparatus, at the same decrease passenger by
Severe jolt impact, improve riding comfort.
