Description
Technical field
The present invention relates to locomotive vibration damping fields, more specifically, being related to a kind of shock absorber.
Background technique
For the shock and vibration that the vehicle that mitigates and decay is subject to because road is uneven in the process of moving, guarantee driving
Ride comfort and comfort improve the service life of vehicle and the stability of manipulation, are provided with shock absorber on vehicle.
In the prior art, Authorization Notice No. is that the Chinese utility model patent of CN206770493U discloses a kind of Novel machine
Vehicle shock absorber includes ram pot, and one end of the ram pot is provided with attachment base, and the other end of the ram pot is inwardly equipped with
Hydraulic stem, the side that the hydraulic stem is located in ram pot are provided with first piston, are arranged between the hydraulic stem and ram pot
There is the first spring, the ram pot circumferential outer surface is arranged with sleeve, and the inside that first piston is located on the hydraulic stem is arranged
There is second piston, second spring is provided between the first piston and second piston, an air bag is provided on the attachment base
Cylinder is provided with circulation road, is located on circulation road on the attachment base and is provided with regulating device between the hydraulic pressure chamber and ram pot.
But this novel locomotive shock absorber is in the process of work, and when piston motion is to room bottom end, piston
Channel blockage between room and air bag being led to, so that residual fraction oil, piston can not move to the bottom of ram pot in ram pot
End, influences the motion range of piston.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide that piston motion can be made to ram pot bottom end
Shock absorber.
To achieve the above object, the present invention provides the following technical scheme that a kind of shock absorber, including piston rod and piston
The first ram pot that bar is slidably connected is fixed on attachment base of the ram pot far from piston rod one end, is fixed on inside attachment base
The cylinder barrel for adjusting component and being fixedly connected with attachment base；The part that piston rod protrudes into inside the first ram pot is fixed with work
Plug, is fixed on piston rod close to the damper piston of attachment base one end；First ram pot is connected with close to the threaded one end of attachment base
Cushion collar；The inner wall of piston and the first ram pot is slidably connected；Damper piston is identical as the radius of cushion collar inner wall, and can
It is slided in the inner wall of cushion collar；The oil worked as a buffer is filled in first ram pot；The side wall of cushion collar offers through-hole,
Through-hole is connected to attachment base；First ram pot and cylinder barrel are each attached to the same side of attachment base, and by setting inside attachment base
The oil duct connection set；Cylinder barrel is sealed far from one end of attachment base；It further include the hydraulic cushion component being arranged on attachment base；Even
The adjustment hole with the cooperation of hydraulic cushion component is also opened on joint chair.
By using above-mentioned technical proposal, piston rod is moved to close to the direction of attachment base, when damper piston move to it is slow
When rushing the inside of set, the through-hole that the oil inside cushion collar can not be opened up by cushion collar side wall, oil passes through out of adjustment hole at this time,
So that the oil remained in the first ram pot is discharged, and cushion collar is moved to by hydraulic cushion component regulating piston bar
Damping when internal.Avoid the feelings for causing damper piston that can not move to cushion collar bottom end because of residual oil in the first ram pot
Condition and appearance avoid the waste in the first ram pot space, and can adjust the damping of this section of stroke according to different situations, fit
With different working conditions.

By using above-mentioned technical proposal, changes centrum and protrude into the length in adjustment hole, to change centrum and adjustment hole
Between semidiameter, change through the oil drain quantity of adjustment hole.Oil drain quantity is big, then damps smaller；Oil drain quantity is small, then damp it is larger,
Oil drain quantity by changing adjustment hole changes damping, the convenient adjusting to damping, and enables shock absorber according to different
Operating condition adjusts different dampings, increases the range used.
The present invention is further arranged to: the regulating wheel and adjustment seat are clamped, and the inner rotation of the regulating wheel is connected with
The connection bolt being threadedly coupled with regulating part.
It by using above-mentioned technical proposal, connects bolt and is threadedly coupled with regulating part, rotation connection bolt can adjust tune
Position of the part in adjustment seat is saved, to change position of the centrum in adjustment hole, changes damping, it is convenient that damping is adjusted
It is whole.
The present invention is further arranged to: the top of regulating wheel offers the adjustment hole for adjusting connection bolt.
By using above-mentioned technical proposal, rotating hole makes can be to connection bolt in state of the regulating wheel not being opened
It is adjusted, the convenient adjusting to regulating part position further facilitates the adjusting to damping.
The present invention is further arranged to: the centre of the regulating part offers cavity；With adjustment seat, regulating part and connection
It adjusts core and together constitutes with air cavity, the bottom end for adjusting core and regulating part is slidably connected.
By using above-mentioned technical proposal, air cavity provides buffering to adjust sliding of the core on regulating part, makes to pass through adjusting
Hole oil throughput have one it is slowly varying, avoid the overexercise of regulating valve from damaging adjustment hole or regulating part.
The present invention is further arranged to: the gas poured in the air cavity is nitrogen or inert gas.
By using above-mentioned technical proposal, nitrogen or inert gas are relatively stable in property, so that the gas in air cavity
It is relatively safer in compressed situation, reduce dangerous generation.
The present invention is further arranged to: a circle groove is also provided on the regulating part, the inside of groove is put for sealing ring
It sets.
By using above-mentioned technical proposal, sealing ring is placed into groove, increases the air-tightness of connector and cage connection,
It reduces and occurs influencing caused by because of the leakage of gas intracavity gas generating the case where adjusting core work.
The present invention is further arranged to: the adjustment seat is internally provided with retention bead, and cooperation is provided on regulating part
Block；And the diameter of coordinating block is greater than the diameter that retention bead is formed by annulus.
By using above-mentioned technical proposal, coordinating block and male cooperation limit the highest for adjusting core and adjustment hole cooperation
Position has avoided the case where adjusting core is not able to cooperate with adjustment hole appearance.
In conclusion the invention has the following advantages: the present invention avoids leading because of residual oil in the first ram pot
The case where causing damper piston that can not move to cushion collar bottom end and appearance, and can be adjusted and be damped according to different situations, increase
The range of shock absorber work.
