Abstract
The utility model discloses an automobile shock absorber piston valve. The upper end face and the lower end face of a piston valve body of a piston rod of a shock absorber are respectively provided with a valve gasket set. When the shock absorber moves on the piston rod at different speeds, damping force can be accurately controlled through control of the diameter, the thickness and the number of gaskets of the valve gasket sets, the number and the size of formed holes or notches, and the arrangement order of each gasket. Required safety and comfort of automobiles in different types are guaranteed when the automobiles are driven on corresponding road conditions.
Description
Technical field
The utility model relates to the automobile absorber field, particularly the piston valve on a kind of automobile absorber.
Background technique
Automobile absorber, when proper functioning, vibrations when between vehicle frame and vehicle bridge and relative movement occurs, the piston in the vibration damper moves up and down, and the fluid the vibration damper chamber in just passes through different holes from a chamber repeatedly and flows in another chamber.The intermolecular interior friction of friction between hole wall and fluid and fluid at this moment forms damping force to vibrations, makes the thump energy be converted into fluid heat energy, be dispersed in the atmosphere by the vibration damper absorption again.When factors such as oil viscosity were constant, damping force was with the speed of related movement between vehicle frame and vehicle bridge increase and decrease, and relevant with the fluid channel cross-section, and therefore what of the fluid by piston valve have very important relation with the performance of vibration damper.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provide a kind of at automobile running in different road surfaces, by changing the damping force of vibration damper, satisfy the auto absorber piston valve of the requirement of vehicle safety and travelling comfort.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of auto absorber piston valve, piston valve is fixedly connected on the bottom of automobile absorber inner piston rod, described piston valve comprises the nut of valve body and fixed valve body, piston rod is provided with a step, be provided with first support pad between the upper end of described valve body and the step, be provided with second support pad between the lower end of valve body and the nut, be provided with in the described valve body and the homoaxial oil inlet passage of piston rod and oil discharge passage, the upper end of described oil inlet passage and oil discharge passage is provided with first shim pack, the lower end of oil inlet passage and oil discharge passage is provided with second shim pack, described first shim pack and second shim pack are made up of some pads, and each pad is provided with some perforates or breach.
As further improvement of the utility model, the pad of described first shim pack and second shim pack is the dismounting combination.
The beneficial effects of the utility model are: having adorned valve owing to the piston valve upper and lower end face of the utility model on piston lever of reducer is shim pack, by to valve being the quantity and size and the control that puts in order of each pad of diameter, thickness, quantity, institute's perforate or the breach of the pad of shim pack, can the damping force size of point-device control vibration damper when piston rod moves with friction speed, guaranteed dissimilar the automobile runnings required Security that possesses and travelling comfort on corresponding road conditions.

Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.
Fig. 1 has shown a kind of mode of execution of a kind of auto absorber piston valve of the utility model, piston valve is fixedly connected on the bottom of automobile absorber inner piston rod 1, described piston valve comprises the nut 3 of valve body 2 and fixed valve body 2, piston rod 1 is provided with a step, be provided with first support pad 4 between the upper end of described valve body 2 and the step, be provided with second support pad 5 between the lower end of valve body 2 and the nut 3, be provided with in the described valve body 2 and piston rod 1 homoaxial oil inlet passage 6 and oil discharge passage 7, the upper end of described oil inlet passage 6 and oil discharge passage 7 is provided with first shim pack 8, the lower end of oil inlet passage 6 and oil discharge passage 7 is provided with second shim pack 9, described first shim pack 8 and second shim pack 9 are made up of some pads, each pad is provided with some perforates or breach, and the pad of described first shim pack 8 and second shim pack 9 is the dismounting combination.
The working procedure of this implementation column: during use, the fixedly connected pallet of piston rod 1 upper end is connected with sheet metal part on the automobile chassis, the vibration damper housing is connected with suspension on the automobile chassis, damping spring on the automobile is sleeved on the housing, and damping spring is connected with the fixedly connected pallet of piston rod 1 upper end; When automobile running during on rough road surface, jolting can appear in vehicle body, and when automobile was descending, damping spring forced belt motor vehicles bodies was slowly descending; When damping spring resets, pinking can appear in car body, at this moment, vibration damper begins to start, the valve body 2 of piston rod 1 up drive piston valve is up, make between oil cylinder and the vibration damper housing oil through bottom valve enter piston valve body 2 in the inner chamber of oil cylinder with the bottom, and the piston valve body 2 of cylinder cavity enters the piston valve body 2 of cylinder cavity with the bottom with the oil in the top through piston valve body 2, first shim pack 8 and second shim pack 9; Piston rod 1 is descending, piston valve body 2 enters in the cylinder cavity piston valve body 2 with top with the oil part of bottom through piston valve body 2, first shim pack 8 and second shim pack 9 in the cylinder cavity, the oil of another part enters between oil cylinder and the vibration damper housing through the oil cylinder bottom valve, thereby finishes whole working procedure.
