Description
Technical field
The utility model relates to a kind of vibration damper of motor vehicles, refers more particularly to a kind of double barreled vibration damper that improves the additional compression resistance.
Background technique
Vibration damper is one of critical piece of Motor Vehicle, and its effect is to improve the motor-driven vehicle going smoothness, can be divided into multiplely by structural type and job specification, and using at present is hydraulic shock absorber more widely.Its principle is when receiving vibration relative movement to occur between vehicle body and vehicle bridge; Piston in the vibration damper moves up and down; Fluid in the vibration damper chamber is flowed in another chamber from a chamber through different holes times without number; Space on piston and the valve seat and its body form various valves, when runner and when in whole valve system the flowing formation damping force of fluid through different valves.When vibration damper can not provide enough damping force, piston will arrive its extreme limit of travel, or runs into base, guide holder or the buffer stopper of clutch release slave cylinder, and makes the vehicle strenuous vibration.If damping force is excessive, piston will be made vibration damper under some state, can not work by locked in clutch release slave cylinder, and consequently vehicle driving makes the passenger feel irksome microseism than flat road surface the time.
Summary of the invention
In order to address the above problem, the utility model provides a kind of dual-tube shock absorber of high additional compression resistance, and it can further improve resistance to compression pression and eliminate vibration damper idle stroke phenomenon in the course of the work, makes the people when taking, increase comfortable feel.
In order to achieve the above object, the technological scheme taked of the utility model is:
A kind of dual-tube shock absorber of high additional compression resistance comprises clutch release slave cylinder, liquid storage cylinder, valve seat assembly, guide holder assembly, piston assembly, piston rod, and wherein the valve seat assembly comprises the valve seat through-hole that valve seat and valve seat are provided with; Guide holder assembly comprises the oil sealing that guide holder and guide holder upper end embed; It is characterized in that be provided with compensated cavity between said clutch release slave cylinder and the liquid storage cylinder, piston assembly is located in the clutch release slave cylinder; Make clutch release slave cylinder form piston upper chamber and piston cavity of resorption; Said piston assembly comprises the piston hole that piston and piston are provided with, and with the piston rod Joint, said piston upper and lower end and valve seat upper and lower end have at least an end to be provided with valve block.
The above piston assembly and piston rod Joint, and under piston rod drives, be implemented in to-and-fro motion in the clutch release slave cylinder.
The utility model beneficial effect is, improved the resistance to compression pression of vibration damper, eliminated vibration damper idle stroke phenomenon at work, and the vibrations when having reduced vehicle driving have increased the ride comfort sense.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1. piston assembly; 2. valve seat assembly; 3. guide holder assembly; 4. piston upper chamber; 5. piston cavity of resorption; 6. guide holder; 7. valve seat; 8. piston; 9. compensated cavity; 10. piston hole; 11. valve seat through-hole; 12. valve block; 13. oil sealing; 14. clutch release slave cylinder; 15 liquid storage cylinders; 16 piston rods.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Can know by accompanying drawing; The utility model comprises clutch release slave cylinder 14, liquid storage cylinder 15, valve seat assembly 2, guide holder assembly 3, piston assembly 1, piston rod 16; Wherein valve seat assembly 2 comprises the valve seat through-hole 11 that valve seat 7 and valve seat are provided with, and guide holder assembly 3 comprises the oil sealing 13 that guide holder 6 and guide holder upper end embed.Between clutch release slave cylinder 14 and liquid storage cylinder 15, be provided with compensated cavity 9, nearly half is full of fluid in compensated cavity 9, and remainder is used for admitting the volume that expands and increase owing to the fluid heating.Piston assembly 1 is located in the clutch release slave cylinder 14, and makes clutch release slave cylinder 14 form piston upper chamber 4 and piston cavity of resorption 5.Said piston assembly 1 comprises the piston hole 10 that piston 8 and piston are provided with, and is provided with valve block 12 at piston 8 and valve seat 7 upper and lower end.Piston assembly 1 and piston rod 16 Joints, and can to-and-fro motion in clutch release slave cylinder.
When the piston 8 in the work does relative motion with clutch release slave cylinder 14; Piston upper chamber 4 flows through piston hole 10 and valve seat through-hole 11 with piston cavity of resorption 5 and compensated cavity 9 interior fluid; And receive the throttling of through hole, played the effect that suppresses between piston 8 and clutch release slave cylinder 14 relative movement by the flow of throttling.Owing to be provided with valve block 12 at piston 8 upper and lower end, the through hole on piston 8 and the valve seat 7 is received valve block 12 opening and closing of elastic pressure, provides or high or low damping characteristic to vibration damper.
When wheel is in when static, piston assembly is in staticly in the vibration damper, and valve block is attached to piston and valve seat upper/lower terminal respectively everywhere, and closes the runner of various valves.
When jumping on the wheel, vibration damper is compressed, and piston moves downward, and a part of fluid flows into first chamber from the active chamber bottom, and the fluid that sinks to partial volume corresponding to piston rod is through being pressed into compensated cavity.The damping force that compression process needs mainly provides thus.Only not enough with system unappeasable the time, the Auxiliary valves that is positioned on the piston works, its residing valve block produces deformation, makes the fluid amount difference that flows through, and produces corresponding different damping force.
When wheel falls, raise at last piston of taking out and the oil pressure between the guide holder, the valve block of main oil mass after restoring extrudes, and the damping force of restoring stroke mainly provides thus, and remaining oil mass is forced through the space between piston rod and the guide holder and extrudes.When piston rod stretches, oil starvation in the piston cavity of resorption, additional fluid self compensation valve sucks, and pulsation circuit fluid obtains cooling through the liquid storage cylinder in active chamber and compensated cavity.
The effect of the utility model middle valve plate has improved the resistance to compression pression of vibration damper, has eliminated vibration damper idle stroke phenomenon at work, and the vibrations when having reduced vehicle driving have increased the ride comfort sense.
