Description
[technical field]
The utility model relates to a kind of at the inner telescopic shock absorber of installing of automobile suspension system.
[background technique]
Vibration damper is equipped with in suspension system inside at most of automobiles.The vibration damper of automobile is also referred to as " suspension ", is made up of jointly spring and vibration damper.Vibration damper is not the weight that is used for supporting vehicle body, but the concussion when being used for suppressing bounce-back after the spring shock-absorbing and absorb the energy of road shocks.Spring plays a part to relax impact, " macro-energy one-shot " become " little energy repeatedly impacts ", and vibration damper is exactly progressively " little energy repeatedly impacts " to be reduced.The damping effect and the working life of how to improve vibration damper are that vibration damper manufacturer pays close attention to always, because the many dirt of working environment, so also will consider the dustproof of vibration damper simultaneously.
[summary of the invention]
In view of the deficiency of existing technology, the utility model provides a kind of good damping effect, long service life, and can fine dust-tight telescopic shock absorber.
The utility model takes following technological scheme to accomplish: telescopic shock absorber, comprise work cylinder barrel, piston rod, piston assembly and compression valve assembly, and piston assembly is located in the work cylinder barrel and is connected with the lower end of piston rod; The upper end of piston rod is connected with the upper end suspension ring of vibration damper; Compression valve assembly is located at the bottom of work cylinder barrel, it is characterized in that: vibration damper also comprises the oil storage inflator, and oil storage inflator fixed cover is located at outside the work cylinder barrel; Valve opening through compression valve assembly between oil storage inflator and the work cylinder barrel communicates; Valve opening through piston assembly between the upper and lower cavity of work cylinder barrel communicates, filling fluid in the work cylinder barrel, the gentle body of filling fluid in the oil storage inflator.
Above-mentioned vibration damper is when compression stroke (refer to that automotive wheel moves nearly vehicle body, vibration damper by compression); This moment, piston moved down, the volume reducing of work cylinder barrel lower chambers, and oil pressure raises; Fluid is flowed through the flowing valve orifice flow of piston assembly to work cylinder barrel epicoele, and epicoele is by piston rod a part of space that accounted for, thereby the volume that reduces less than cavity of resorption of the volume that increases of epicoele; So part fluid is just pushed the compression valve opening of compression valve assembly open, flows back to the oil storage inflator, so gas pressurized in the oil storage inflator; Increase the damping force of compression movement, improve damping effect; Vibration damper is (refer to wheel away from vehicle body, vibration damper is stretched) when extension stroke, and at this moment piston moves up; Work cylinder barrel epicoele oil pressure raises, and the fluid in the flowing valve bore closure, epicoele is pushed the rebound valve orifice flow of piston assembly open and gone into work cylinder barrel cavity of resorption; Because the existence of piston rod, the fluid that comes from epicoele stream is not enough to be full of the volume that cavity of resorption increases, and causes cavity of resorption to produce certain degree of vacuum; At this moment the recuperation valve orifice flow of pushing compression valve assembly open of the fluid in the oil storage inflator advances work cylinder barrel cavity of resorption and replenishes; Gas in the oil storage this moment inflator plays restraining function to fluid, increases the damping force of stretching exercise, improves damping effect.Because damping effect improves, so also be improved the working life of vibration damper.
Outside the oil storage inflator, be movably equipped with dustproof sleeve, the length of dustproof sleeve is suitable with the stroke of said piston assembly, and the dust cover that dustproof sleeve top is provided with and the upper end suspension ring welding of vibration damper are fixing.The setting of dustproof sleeve can not be exposed in the working environment motive sealing of piston rod upper end fully, so vibration damper can finely prevent dust.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
[embodiment]
As shown in the figure, the telescopic shock absorber of the utility model comprises work cylinder barrel 5, oil storage inflator 4, dustproof sleeve 3, piston rod 6, piston assembly 7 and compression valve assembly 8; Oil storage inflator 4 fixed covers are located at outside the work cylinder barrel 5, and piston assembly 7 is located in the work cylinder barrel 5 and is connected with the lower end of piston rod 6, and the upper end of piston rod 6 is connected with the upper end suspension ring 1 of vibration damper; Compression valve assembly 8 is located at the bottom of work cylinder barrel 5; The base 9 that compression valve assembly 8 bottoms are provided with is fixedly connected on the bottom of oil storage inflator 4, and the valve opening through compression valve assembly 8 between oil storage inflator 4 and the work cylinder barrel 5 communicates, and compression valve assembly 8 is provided with compensation valve opening and compression valve opening; Valve opening through piston assembly 7 between the upper and lower cavity of work cylinder barrel 5 communicates; Piston assembly 7 is provided with the circulation valve opening and upholds valve opening, filling fluid 13 in the work cylinder barrel 5, half filling fluid 11, half filling pressurized gas 12 in the oil storage inflator 4; Said dustproof sleeve 3 is movable the setting outside oil storage inflator 4; The length of dustproof sleeve 3 is suitable with the stroke of said piston assembly 7, and the dust cover 2 that dustproof sleeve 3 tops are provided with is fixing with upper end suspension ring 1 welding of vibration damper, and the lower end suspension ring 10 of vibration damper are weldingly fixed on the said base 9.
Above-mentioned vibration damper, when compression stroke, this moment, piston moved down, the volume reducing of work cylinder barrel lower chambers; Oil pressure raises, and fluid is flowed through the flowing valve orifice flow of piston assembly to work cylinder barrel epicoele, and epicoele is by piston rod a part of space that accounted for; Thereby the volume that reduces less than cavity of resorption of the volume that increases of epicoele, so a part of fluid is just pushed the compression valve opening of compression valve assembly open, flow back to the oil storage inflator; So the gas pressurized in the oil storage inflator, the damping force of increase compression movement improves damping effect; Vibration damper is when extension stroke, and at this moment piston moves up, and work cylinder barrel epicoele oil pressure raises; Fluid in the flowing valve bore closure, epicoele is pushed the rebound valve orifice flow of piston assembly open and is gone into work cylinder barrel cavity of resorption, because the existence of piston rod; The fluid that comes from epicoele stream is not enough to be full of the volume that cavity of resorption increases; Cause cavity of resorption to produce certain degree of vacuum, at this moment the recuperation valve orifice flow of pushing compression valve assembly open of the fluid in the oil storage inflator advances work cylinder barrel cavity of resorption and replenishes, and the gas in the oil storage this moment inflator plays restraining function to fluid; Increase the damping force of stretching exercise, improve damping effect.
