Abstract
The utility model discloses a valve seat for a vehicle shock absorber. The valve seat comprises a valve seat body (1), a plurality of inner ring throttling holes (2) and a plurality of outer ring throttling holes (3) which are axially communicated and distributed at circular intervals are formed in the groove part on the upper end surface of the valve seat body (1), and a plurality of axially convex bulges (4) are arranged on the valve seat body between two adjacent outer ring throttling holes (3). The valve seat has the advantages that the outer ring valve plate is not easy to deform, the damping force of the shock absorber is stable, and the service life is long.
Description
Technical field
The utility model relates to automobile hydraulic vibration damper field, specifically be a kind of valve seat for auto shock-absorber.
Background technique
The main effect of automobile absorber is when being subjected to vibration relative movement to occur between vehicle body and vehicle bridge or wheel and the vehicle body, piston in the vibration damper moves up and down, and the pressure oil in the vibration damper just flows in the shock absorber oil storage cylinder through different throttle orifices from a vibration damper clutch release slave cylinder repeatedly.The intermolecular interior friction of friction between hole wall and the hydraulic oil and hydraulic oil at this moment forms damping force to vibration, makes automobile vibrational energy be converted into fluid heat energy, is dispersed in the atmosphere by the vibration damper absorption again.Existing automobile absorber, comprise the vibration damper clutch release slave cylinder, be nested with at oil storage cylinder, the shock absorber piston that matches with the vibration damper clutch release slave cylinder in the vibration damper clutch release slave cylinder outside and the vibration damper valve seat that is arranged on the clutch release slave cylinder bottom, the inner bottom surface of the bottom surface of valve seat and vibration damper clutch release slave cylinder is fitted, be provided with the hydraulic oil channel of notch at interval in the bottom surface of valve seat, center at valve seat is provided with axis hole, cooperates in the axis hole main shaft is installed; On valve seat, also be provided with axially communicate be circular inner ring throttle orifice spaced apart and outer ring throttle orifice, be provided with the inner ring valve block that the inner ring throttle orifice is used in the bottom of valve seat, the top of valve seat is provided with the outer ring valve block that the outer ring throttle orifice is used, described inner ring valve block and outer ring valve block all are socketed on the main shaft, by the cooperation that misplaces mutually of inner ring valve block and inner ring throttle orifice, and outer ring valve block and the outer ring throttle orifice mistake oil mass that cooperation regulates inner ring throttle orifice and outer ring throttle orifice that misplaces mutually, to reach the purpose of vibration damper damping.
The valve seat for auto shock-absorber of prior art, because the spacing between the throttle orifice of outer ring is bigger, particularly under the situation about sharply shaking in the automobile traveling process, the hydraulic oil of high-speed motion is bigger to the impact force of outer ring valve block; Use can make the outer ring valve block between the throttle orifice of outer ring partly deform for a long time, and the outer ring valve block after the distortion can make the mistake oil mass of outer ring throttle orifice increase, thereby makes the damping force instability of vibration damper, shortens the working life of vibration damper.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provide a kind of make the outer ring valve block not yielding, make that damping force of vibration damper is stable, the valve seat for auto shock-absorber of long service life.
Technical solution of the present utility model is, a kind of valve seat for auto shock-absorber with following structure is provided: it comprises the valve seat body, the groove part of described valve seat body upper-end surface be provided with axially communicate be circular a plurality of inner ring throttle orifices spaced apart and a plurality of outer rings throttle orifice, the valve seat body between described every adjacent two outer ring throttle orifices is provided with the projection of a plurality of axial epireliefs.
After adopting above structure, the utility model valve seat for auto shock-absorber compared with prior art, have the following advantages: the valve seat body between every adjacent two the outer ring throttle orifices of employing is provided with the projection of a plurality of axial epireliefs, this projection has reduced the movable amplitude of outer ring valve block in the process of the high-speed motion of outer ring valve block.Under the high speed impact of hydraulic oil, the outer ring valve block has obtained buffering, makes the outer ring valve block not yielding, has reduced the leakage of hydraulic oil, thereby makes the damping force of vibration damper stable, has prolonged the working life of automobile absorber.
Description of drawings
Fig. 1 is the plan structure schematic representation of the utility model valve seat for auto shock-absorber.
Fig. 2 is the structural representation of looking up of the utility model valve seat for auto shock-absorber.
As shown in the figure:
1, valve seat body, 2, the inner ring throttle orifice, 3, the outer ring throttle orifice, 4, projection.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2.
The utility model valve seat for auto shock-absorber, it comprises valve seat body 1, the groove part of described valve seat body 1 upper-end surface be provided with axially communicate be circular a plurality of inner ring throttle orifices 2 spaced apart and a plurality of outer rings throttle orifice 3, the valve seat body between described every adjacent two outer ring throttle orifices 3 is provided with the projection 4 of a plurality of axial epireliefs.
Described protruding 4 height is a little less than the upper-end surface of valve seat body 1.
Claims (2)
1. valve seat for auto shock-absorber, it comprises valve seat body (1), the groove part of described valve seat body (1) upper-end surface is provided with and axially communicates and be circular a plurality of inner ring throttle orifices (2) spaced apart and a plurality of outer rings throttle orifices (3), it is characterized in that: the valve seat body between described every adjacent two outer ring throttle orifices (3) is provided with the projection (4) of a plurality of axial epireliefs.
2. valve seat for auto shock-absorber according to claim 1 is characterized in that: the height of described projection (4) is a little less than the upper-end surface of valve seat body (1).
