Abstract
The utility model relates to a damper bottom valve seat, which comprises a valve seat body. A valve core is arranged at the center of the valve seat body, an inner channel and an outer channel are arranged around the valve core, and a throttle valve sheet is arranged below the inner channel. A compressed valve sheet is arranged below the throttle valve sheet, and an upper compressed valve sheet is arranged above the throttle valve sheet. By means of the arrangement of the upper compressed valve sheet, damper oil is separated by the upper compressed valve sheet. When an automobile is at a rest state, the damper oil cannot flow into an oil storage barrel under the action of gravity, and a working cylinder is always full of the oil. Oil loss travel distortion and noise cannot happen at an initial phase of a damper piston rod, thereby reducing noise of the whole automobile and improving driving comfortableness.
Description
Technical field
The utility model relates to the foot valve seat on a kind of vibration damper.
Background technique
In recent years, along with automotive industry, the particularly fast development of car industry as the vibration damper of the important accessory of automobile, has also obtained development rapidly.Automobile absorber is a kind of damping member, is one of important composition element of automobile suspension system, and smoothness, travelling comfort, Security, steering operation property and the passing ability of vehicle driving played conclusive effect.Be widely used in the independent suspension type vibration damper on the car now; Be bitubular hydraulic pressure or pneumatic bumper more than 95% since its to have quality little, stable performance; Reliable operation; Be fit to advantages such as production in enormous quantities, become the main flow of automobile absorber, wherein the foot valve seat assembly is one of important spare part wherein.The shock absorption principle of vibration damper is a piston rod in the process of motion, and shock absorber fluid constantly circulates between clutch release slave cylinder and oil storage cylinder through foot valve seat assembly and piston assembly, is dispersed in the air thereby be converted into heat energy to kinetic energy.In the process of piston rod pull-up, the compensation valve block on the foot valve seat assembly is opened, and shock absorber fluid gets in the clutch release slave cylinder from oil storage cylinder, and in the process of piston rod compression, the shock absorber fluid in the clutch release slave cylinder is backed down through the compression valve block on the valve body and gets in the oil storage cylinder.In the prior art, as shown in Figure 1, below internal channel, can be provided for the throttle valve plate 31 of throttling; Throttle valve plate 31 belows are provided with compression valve block 41; And vibration damper shock absorber fluid in the clutch release slave cylinder in put procedure can flow in the oil storage cylinder through the aperture on the throttle valve plate, and vibration damper has one section not have shock absorber fluid in the initial movement process in the clutch release slave cylinder, make vibration damper generation idle running sex distortion and sound; Reduce the smoothness of vehicle driving, increased the car load noise.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the utility model provide a kind of can avoid automobile under static state shock absorber fluid flow into the vibration damper foot valve seat in the oil storage cylinder.
The technological scheme that the utility model solves its technical problem is:
A kind of vibration damper foot valve seat; Comprise valve body; The center of valve body is provided with spool, is provided with internal channel and external chennel around the spool, and the below of described internal channel is provided with throttle valve plate; The below of described throttle valve plate is provided with the compression valve block, and the top of described throttle valve plate also is provided with compresses valve block on one.
As improvement; Be convexly equipped with the first valve line on the lower end surface of valve body downwards; The inboard of the described first valve line also convexes with the second valve line downwards; And the described second valve line is positioned at the top of the said first valve line, and described throttle valve plate is arranged on the described first valve line, and the described compression valve block of going up is arranged on the described second valve line.
Above throttle valve plate, promptly be provided with again between throttle valve plate and the internal channel and compress valve block on one, and go up the top that the compression valve block is arranged on throttle valve plate; Then shock absorber fluid is because action of gravity; When internal channel got off, because the buffer action of last compression valve block, shock absorber fluid can not leak; Then remain shock absorber fluid in the clutch release slave cylinder, idle running sex distortion and sound can not occur.
The beneficial effect of the utility model is: the utility model is through the setting of last compression valve block; Make shock absorber fluid separated by last compression valve block, then automobile is when state of rest, and shock absorber fluid can't flow under the influence of gravity in the oil storage cylinder; All the time be full of oil in the clutch release slave cylinder; Idle running sex distortion and sound can not take place in the starting stage in piston lever of reducer, have reduced the car load noise, have improved the travelling comfort of driving.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 2, a kind of vibration damper foot valve seat comprises valve body 1; The center of valve body 1 is provided with spool 7, is provided with internal channel 5 and external chennel 6 around the spool, and the upper-end surface of valve body is provided with compression compensation valve block 8; Compression compensation valve block top is provided with compression counterbalance spring 9; The below of internal channel is provided with throttle valve plate 3, and the below of throttle valve plate 3 is provided with compression valve block 4, and the lower end surface of valve body is provided with the first valve line 11 that is used for placing throttle valve plate; The inboard of the first valve line also convexes with the second valve line 10; And the second valve line 10 is positioned at the top of the first valve line 11, and compression valve block 2 also is set between throttle valve plate 3 and the internal channel on one, on compress valve block 2 and be arranged on the described second valve line.
Above throttle valve plate, compression valve block 2 on promptly is set between throttle valve plate and the internal channel again, and goes up the inboard that the compression valve block is arranged on throttle valve plate; Then shock absorber fluid is because action of gravity; When internal channel gets off, because the setting of last compression valve block can not leak; Then remain shock absorber fluid in the clutch release slave cylinder, idle running sex distortion and sound can not occur.
