Abstract
The utility model discloses a buffer valve seat for an automobile shock absorber. The buffer valve seat for the automobile shock absorber comprises a valve seat body with a groove on the upper end surface. Inside the groove is provided with a plurality of inner ring orifices and a plurality of outer ring orifices, wherein the inner ring orifices and outer ring orifices are arranged to be communicated with one another axially and to be in a circle at regular intervals. Annular footsteps higher than the bottom face of the groove are arranged in the groove on the upper end surface of the valve seat body along the inner wall of the groove, and the annular footsteps are provided with matching rubber gaskets. The buffer valve seat for the automobile shock absorber designed in above mode decreases the activity extend of the outer ring valve blocks in high-speed motion, buffers the outer ring valve blocks from the high-speed shock of hydraulic oil by providing the annular footsteps with rubber gaskets, makes the outer ring valve blocks not easy to deform, decreases the hydraulic oil leakage, stabilizes the damping force of the shock absorber and prolongs the service life of the automobile shock absorber.
Description
Technical field
The utility model relates to the automobile hydraulic shock-damping device field, is specially a kind of automobile absorber buffering type valve seat.
Background technique
Vibration damper is the rapid wear accessory in the automobile using process, and vibration damper work quality will directly affect the stationarity of automobile running and the life-span of other parts.The Main Function 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 at this moment friction between hole wall and the hydraulic oil and the intermolecular interior friction of hydraulic oil forms damping force to vibration, makes automobile vibrational energy be converted into fluid heat energy, absorbed by vibration damper to be dispersed in the atmosphere again.
Existing valve seat for auto shock-absorber, in the situation about in the automobile traveling process, sharply shaking, the hydraulic oil of high-speed motion is larger 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, outer ring valve block after the distortion can make the mistake oil mass of outer ring throttle orifice increase, thereby make the damping force of vibration damper unstable, shorten the working life of vibration damper.
The model utility content
The purpose of this utility model provides a kind of automobile absorber buffering type valve seat, and traditional valve seat makes valve block deform in use easily in the prior art to solve, so that the damping force of vibration damper is unstable, and then affects the vibration damper problem in working life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of automobile absorber buffering type valve seat, include the valve seat body, be provided with in the groove of described valve seat body upper-end surface and axially communicate and be circular several inner ring throttle orifices spaced apart and several outer ring throttle orifices, it is characterized in that: the groove of described valve seat body upper-end surface is provided with the ring-shaped step that is higher than groove floor along the groove inwall, and described ring-shaped step is provided with the rubber washer that is mated.
Described a kind of automobile absorber buffering type valve seat, it is characterized in that: described ring-shaped step is provided with annular groove, and described rubber washer is inlaid on the ring-shaped step by the annular groove on the ring-shaped step.
The beneficial effects of the utility model are:
The utility model adopts the design that is higher than the ring-shaped step of groove floor at the groove of valve seat body upper-end surface along the setting of groove inwall, reduced the movable amplitude of outer ring valve block in the high-speed motion process, and ring-shaped step is provided with rubber washer, so that the outer ring valve block obtains buffering under the high speed impact of hydraulic oil, and then be difficult for deforming, reduce the leakage of hydraulic oil, thereby made the damping force of vibration damper stable, prolonged the working life of automobile absorber.
