Abstract
The utility model discloses a shock absorber piston component and especially discloses a piston connecting rod and piston sub-assembly. The piston connecting rod and piston sub-assembly comprises a connecting rod, a piston, a flow valve plate and a flow valve spring which are arranged on the upper end surface of the piston from the inner side in sequence, and a restoring throttling valve plate, a restoring valve plate, a rebound valve spring seat and a rebound valve spring which are arranged on the lower end surface of the piston from the inner side in sequence, wherein, an O-shaped ring is arranged between the rebound valve spring seat and the restoring valve plate, a piston locking nut connected on the connecting rod through a thread is arranged on the lower end surface of the piston, and a connecting rod nut propped with the rebound valve spring is arranged on the lower end surface of the rebound valve spring. Due to the adoption of the technical scheme, the provided piston connecting rod and piston sub-assembly enhances the sealing performance and the stability and has very stable damping; and since the piston connecting rod and piston sub-assembly is fixed by adopting the double-nut structure, the piston is fixed through the piston locking nut, the rebound valve spring is fixed through the connecting rod nut, the piston connecting rod and piston sub-assembly is not required to be riveted at the end of the connecting rod, the working procedures are reduced, and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of piston assembly, more specifically says, it relates to a kind of piston rod piston sub-assembly.
Background technique
In vibration damper, the stable sealing of piston rod piston sub-assembly directly has influence on the effect of vibration damper.The deficiencies in the prior art are at present: piston recovery part sealing is not enough, causes leakage easily; Long-term use rear spring rigidity and elasticity change and cause the damping instability; Interlinking lever end need be riveted, and operation is loaded down with trivial details is inconvenient to keep in repair.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of raising sealing, stability are provided, and just with production, reduces the piston rod piston sub-assembly of operation.
Piston rod piston sub-assembly of the present utility model, comprise connecting rod, circulation valve block, flowing valve spring that piston, described piston upper-end surface set gradually from the inboard, the recovery throttle valve plate that described piston lower surface sets gradually from the inboard, recovery valve block, rebuilt valve spring seat, rebuilt valve spring, be provided with O type circle between described rebuilt valve spring seat and the recovery valve block, piston lower surface is provided with by being threaded in the lock piston jack panel on the connecting rod, and the return spring lower end surface is provided with the connecting rod nut with its apical grafting.
The rebuilt valve spring seat is an annular step scalariform platform shape seat, and the outer convex edge of rebuilt valve spring seat face forms a toroidal cavity with recovery valve block apical grafting and in the bottom, and described O type circle is located in the toroidal cavity.
Because adopt technique scheme, the piston rod piston sub-assembly that the utility model provides has improved sealing, stability, and damping is very stable.Because adopt double nuts structure to fix, lock piston jack panel fixed piston, connecting rod nut is the rebuilt valve spring fixedly, so this piston rod piston sub-assembly need not to rivet at interlinking lever end, effectively reduces operation, convenient for maintaining.
Description of drawings
Fig. 1 is the utility model embodiment's a main cut-away view.
1 connecting rod; 2 pistons; 3 circulation valve blocks; 4 flowing valve springs; 5 restore throttle valve plate; 6 restore valve block; 7 rebuilt valve spring seats; 8 rebuilt valve springs; 9O type circle; 10 lock piston jack panels; 11 connecting rod nuts.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified model and the equivalent in the scope of the present utility model that can be included in attached claims qualification.
Referring to Fig. 1, the piston rod piston sub-assembly of Jie Shaoing generally is used for vibration damper here, yet should know that the utility model also can be used for the piston assembly of other structures.Piston rod piston sub-assembly, comprise connecting rod 1, circulation valve block 3, flowing valve spring 4 that piston 2, described piston 2 upper-end surfaces set gradually from the inboard, the recovery throttle valve plate 5 that described piston 2 lower end surfaces set gradually from the inboard, recovery valve block 6, rebuilt valve spring seat 7, rebuilt valve spring 8, be provided with O type circle 9 between described rebuilt valve spring seat 7 and the recovery valve block 6, piston 2 lower end surfaces are provided with by the lock piston jack panel 10 that is threaded on the connecting rod 1, and rebuilt valve spring 8 lower end surfaces are provided with the connecting rod nut 11 with its apical grafting.Rebuilt valve spring seat 7 is an annular step scalariform platform shape seat, and rebuilt valve spring seat 7 outer convex edge faces form a toroidal cavity with recovery valve block 6 apical graftings and in the bottom, and described O type circle 9 is located in the toroidal cavity.
In the use, when connecting rod 1 and piston 2 moved down, fluid entered inner cavity of cylinder by the filler opening on the piston 2 by pushing circulation valve block 3 open.When connecting rod 1 and piston 2 moved up, fluid entered the cylinder barrel exocoel by the oil outlet on the piston 2 by pushing open to restore throttle valve plate 5 and restore valve block 6.Fluid all can produce certain damping by circulation valve block 3 with restoring throttle valve plate 5 and restoring valve block 6, and by having adopted O type circle 9 to seal, fluid is easy to leak not, has improved sealing, the stability of piston rod piston sub-assembly, and damping is very stable.Because adopt double nuts structure to fix, lock piston jack panel 10 fixed pistons 2, connecting rod nut 11 is rebuilt valve spring 8 fixedly, so this piston rod piston sub-assembly need not to rivet in connecting rod 1 end, effectively reduces operation, convenient for maintaining.
