Technical Field
The utility model relates to the field of automotive equipment, especially, relate to a shock absorber piston.
Background
The shock absorber is a very important part on the automobile, the piston on the shock absorber plays a very important role in the performance of the shock absorber, the structure of the piston of the traditional shock absorber is shown in figure 1, the piston of the structure comprises a plug body (1), a central mounting hole (102) and a through hole (101) are formed in the plug body, during assembly, a valve plate (2) is assembled on two sides of the plug body (1), the valve plate is tightly attached to partial orifices of the through hole (the tight attachment part can leak oil), and the orifice of the through hole on only one side of the plug body is ensured to be in an open state (namely oil can only flow in a single direction), so the piston of the traditional structure is unidirectional, the damping force of the piston of the structure is relatively weak, and the piston cannot meet long-time alternating large load and complex road conditions.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to above-mentioned problem, a bumper shock absorber piston is proposed.
The utility model adopts the following technical scheme:
the utility model provides a shock absorber piston, includes the cock body, seted up central mounting hole and a plurality of opening on the cock body, be provided with the valve block on the cock body, an drill way of every opening is pasted tightly by the valve block, and another drill way of every opening is in the state that is not pasted tightly, and the both sides of cock body all have the drill way of the opening that is not pasted tightly by the valve block.
In the piston with the structure, although the valve plate is tightly attached to the orifice of the circulation hole, the valve plate does not block the circulation hole, and the gap between the valve plate and the piston body can still expose the liquid in the circulation hole. And because the oil liquid on the two sides of the piston can be convected, the phenomenon of oil shortage can be avoided in the using process.
Optionally, the central mounting hole is a circular mounting hole.
Optionally, a stepped groove is arranged at the orifice of the flow hole.
Optionally, the valve plate abuts against an orifice of the flow hole with a step groove.
Set up the step groove, the valve block pastes the step groove of opening, can increase the oil storage volume in the opening like this, improves the stability of whole bumper shock absorber at the during operation.
Alternatively, a step groove is provided at only one and only one of the orifices of each flow hole.
Optionally, the valve plate is mounted on two sides of the plug body through fasteners.
The specific fastener can be a bolt assembly and can also be a part of other structures.
Optionally, two sides of the plug body are provided with at least 2 valve plates.
Optionally, two adjacent valve plates are in a tight state.
The utility model has the advantages that: the two sides of the plug body are provided with the orifices which are not tightly adhered by the valve plate, so that liquid on the two sides of the piston can convect when the piston with the structure works, the idle stroke phenomenon is avoided in the compression process, the compression damping force can be enhanced, and the service life of a valve system is prolonged; and the phenomenon of oil shortage can be avoided in the using process.
Description of the drawings:
figure 1 is a schematic diagram of a piston installation of a conventional shock absorber,
figure 2 is a schematic diagram of the installation of the damper piston.
The figures are numbered: 1. a plug body; 101. a flow-through hole; 102. a central mounting hole; 103. a step groove; 2. a valve plate; 3. a fastener.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 2, the shock absorber piston comprises a plug body 1, wherein a central mounting hole 102 and a plurality of circulation holes 101 are formed in the plug body 1, a valve plate is arranged on the plug body 1, one hole of each circulation hole 101 is attached by the valve plate, the other hole of each circulation hole 101 is not attached, and holes of the circulation holes 101 which are not attached by the valve plate are formed in two sides of the plug body 1.
In the piston with the structure, although the valve plate is tightly attached to the orifice of the flow hole 101, the flow hole 101 is not blocked by the valve plate, the gap between the valve plate and the plug body 1 can still expose the liquid in the flow hole 101, and the piston with the structure can realize convection of the liquid in the working cylinder (the piston is assembled in the working cylinder) during working because the orifices which are not tightly attached by the valve plate (namely the orifices are in a completely open state) are arranged on the two sides of the plug body 1, so that the idle stroke phenomenon is avoided in the compression process, the compression damping force can be enhanced, and the service life of a valve system is prolonged. And because the oil liquid on the two sides of the piston can be convected, the phenomenon of oil shortage can be avoided in the using process.
As shown in fig. 2, the central mounting hole 102 is a circular mounting hole.
As shown in fig. 2, a stepped groove 103 is provided at the orifice of the flow hole 101.
As shown in fig. 2, the valve sheet 2 abuts on the opening of the flow hole 101 having the stepped groove 103.
The step groove 103 is arranged, and the valve plate 2 is attached to the step groove 103 of the flow hole 101, so that the oil storage amount in the flow hole 101 can be increased, and the stability of the whole shock absorber in working is improved.
As shown in fig. 2, each flow hole 101 has a step groove 103 provided at only one orifice.
As shown in fig. 2, the valve plate 2 is mounted on both sides of the plug body 1 by fasteners 3.
The fastener 3 may be a bolt assembly or a part of other structure.
As shown in the attached figure 2, at least 2 valve plates are arranged on two sides of the plug body 1.
As shown in figure 2, two adjacent valve plates are in a close state.
The aforesaid only is the preferred embodiment of the utility model discloses a not consequently restrict promptly the utility model discloses a patent protection scope, all applications the utility model discloses the equivalent transform that the specification was done, direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses a protection scope.
