Abstract
The utility model discloses a kind of rebound valve of shock absorber assembly, be included in the circulation back-up ring that piston lever of reducer bottom is installed, circulation valve block, restore throttle valve plate, piston body, restore valve block and restore adjustment packing ring, it is characterized in that: circulation back-up ring, circulation valve block, restore throttle valve plate, piston body, restoring valve block and restoring adjustment packing ring is movably set on piston rod, described bottom of restoring adjustment packing ring is provided with return spring, return spring upper end is provided with spring seat and is resisted against the bottom of restoring valve block, the lower end of return spring is provided with restores nut thread connection on the piston rod, the top of restoring nut compresses restores adjustment packing ring.The utility model adds the regulation range of recovery damping force, has adapted to the recovery damping force requirement of different automobile types vibration damper.
Description
Technical field
The utility model relates to the vibration damper applied in automobile suspension system, particularly a kind of rebuilt valve assembly of vibration damper.
Background technique
In the suspension system inside of most of automobile, vibration damper is housed, the vibration damper of automobile, also referred to as " suspension ", is made up of jointly spring and vibration damper, and vibration damper operationally can be in continuously compression and drawing process.In vibration damper, the rebuilt valve assembly being arranged on piston rod bottom sets up recovery damping force for piston rod vibration damper when stretching.The rebound valve of shock absorber assembly of prior art, its adjustment recovery damping force is the damping force size of the adjustment friction speed gears such as the external diameter restoring the groove width of throttle valve plate and quantity, the quantity of recovery valve block and thickness by adjustment and restore adjustment packing ring, the regulation range of recovery damping force is limited, can not adapt to the recovery damping force requirement of different automobile types vibration damper completely.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of regulation range increasing recovery damping force, can adapt to the rebound valve of shock absorber assembly of different automobile types vibration damper recovery damping force requirement.
The utility model takes following technological scheme:
Rebound valve of shock absorber assembly, be included in the circulation back-up ring that piston lever of reducer bottom is installed, circulation valve block, restore throttle valve plate, piston body, restore valve block and restore adjustment packing ring, it is characterized in that: circulation back-up ring, circulation valve block, restore throttle valve plate, piston body, restoring valve block and restoring adjustment packing ring is movably set on piston rod, described bottom of restoring adjustment packing ring is provided with return spring, return spring upper end is provided with spring seat and is resisted against the bottom of restoring valve block, the lower end of return spring is provided with restores nut thread connection on the piston rod, the top of restoring nut compresses restores adjustment packing ring.
The sheathed piston jacket of cylindrical of described piston body.
After adopting technique scheme, the utility model can also adjust the size of recovery damping force by the steel wire diameter and the number of turns adjusting return spring, add the regulation range of recovery damping force, thus the recovery damping force requirement of different automobile types vibration damper can have been adapted to completely.Further, when the design of piston jacket can better ensure that rebuilt valve is up and down in clutch release slave cylinder, the sealing of clutch release slave cylinder upper and lower cavity, prevents interior leakage, also contributes to the damping performance improving vibration damper.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the working principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in the figure, rebound valve of shock absorber assembly of the present utility model, be included in the circulation back-up ring 2 that piston lever of reducer 1 bottom is installed, circulation valve block 3, restore throttle valve plate 4, piston body 5, restore valve block 7 and restore adjustment packing ring 8, circulation back-up ring 2, circulation valve block 3, restore throttle valve plate 4, piston body 5, restoring valve block 7 and restoring adjustment packing ring 8 is movably set on piston rod 1, described bottom of restoring adjustment packing ring 8 is provided with return spring 10, return spring 10 upper end is provided with spring seat 9 and is resisted against the bottom of restoring valve block 7, the lower end of return spring 10 is provided with recovery nut 11 and is threaded on piston rod 1, the top of restoring nut 11 compresses restores adjustment packing ring 8, the sheathed piston jacket 6 of cylindrical of described piston body 5.
Above-mentioned rebound valve of shock absorber assembly, its adjustment recovery damping force can restore groove width and quantity, the quantity of recovery valve block and the damping force size of thickness, the recovery adjustment external diameter of packing ring and the adjustment such as the steel wire diameter of return spring and number of turns friction speed gear of throttle valve plate by adjustment, add the regulation range of recovery damping force, adapt to the recovery damping force requirement of different automobile types vibration damper.
Claims (2)
