In the technique scheme, preferred, said through hole is arranged on the said dividing plate.As long as it is inner just passable with shoe cream room that through hole can be communicated with inner core, also can be arranged in theory on the inner core sidewall, still can make the inner wall shape generation certain deformation of inner core like this, influence cooperating of piston and inner core inwall.Just can not produce this problem and be arranged on the dividing plate.
According to last technological scheme, preferred, said through hole is communicated with the said oil storage portion of the inner and said dividing plate opposite side of the said inner core of said dividing plate one side.Design like this, the fluid of dividing plate one side carries out damping function to the dividing plate opposite side, and the resistance of the piston rod of a side is provided by the damping hole of opposite side, makes to help the damping of vehicle by the stressed balanced more of both sides piston rod.
In the technique scheme, preferred, be provided with air bag in the said oil storage portion.Be filled with the gas of certain pressure in the air bag, or when the situation of horizontal inclination appearred in the utility model, the situation of monolateral oil starvation possibly appear in oil storage portion, at this moment that part of pressure of oil starvation reduces, and airbag inflation makes fluid continue to be full of oil storage portion.Prevent that the piston resistance from reducing suddenly, can not play damping effect.
In the technique scheme, preferred, the other end of said piston rod is provided with suspension ring.The other end of two piston rods all is suspension ring, and the structure of this pair of suspension ring is convenient to match with different vehicles.
In the technique scheme, preferred, said piston rod stretches out said urceolus and partly is outside equipped with dust-proof cover.Dust-proof cover is used to protect piston rod not encroached on by extraneous dust.
The beneficial effect of the utility model is: the two ends of urceolus respectively are provided with a damping hole; Two damping holes all play cushioning effect; On running into vehicle between each wheel during unbalance stress, it is unbalance effectively to alleviate the moment of vehicle when running at high speed and turn.
Description of drawings
Fig. 1 is the utility model embodiment's a floor map.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1, double-acting shock absorber comprises urceolus 1, is provided with dividing plate 2 in the urceolus 1, dividing plate each side be provided with an inner core 31,32.Form oil storage portion 41 between the inner core 31 in left side and the urceolus 1, form oil storage portion 42 between the inner core 32 on right side and the urceolus 1, form two through holes 21,22 on the dividing plate 2, through hole 21 is communicated with inner core 31 inner and oil storage portions 42, and through hole 22 is communicated with inner core 32 and oil storage portion 41.Be provided with air bag 411,412 in the oil storage portion 41,42.
Slidely connect piston 51 on inner core 31 inwalls, piston 51 is fixed with the right-hand member of piston rod 53, and the left end of piston rod 53 passes outside the urceolus 1, and the right-hand member of piston rod 53 is fixed with suspension ring 531.Slidely connect piston 52 on inner core 32 inwalls, piston 52 is fixed with the left end of piston rod 54, and the right-hand member of piston rod 54 passes outside the urceolus 1, and the right-hand member of piston rod 54 is fixed with suspension ring 532.Piston rod 53,54 stretches out urceolus 1 part and is outside equipped with dust-proof cover 81,82.
The two ends of urceolus 1 are provided with guider 61,62 and oil sealing 71,72.Guider 61,62 is the part of an annular; The outer ring of guider 61,62 have the two ends diameter different but coaxial cylndrical surface; The cylndrical surface that the race diameter of guider 61,62 is bigger and the inwall of urceolus 1 fit tightly and form sealing; Matching with the inwall of inner core 31,32 in the less cylndrical surface of guider 61,62 race diameters, has so just guaranteed urceolus 1 and inner core 31, the coaxality between 32.The outer surface secret of the inner ring of guider 61,62 and piston rod 53,54 is fitted, and forms good sealing, and the inner ring of guider 61,62 has also guaranteed the axis of piston rod 53,54 and the axis coaxle of urceolus 1 simultaneously.The end face that guider 61,62 relies on urceolus 1 outside is provided with oil sealing 71,72, oil sealing 71,72 and guider 61, formation shoe cream room 63,64 between 62.Guider 61,62 is provided with the damping hole 65,66 that is communicated with oil storage portion 41,42 and shoe cream room 63,64.
The utility model cooperates returning spring to use; Be installed in each wheel place of vehicle, jolt or when shaking, piston rod 53,54 receives the effect of power simultaneously when vehicle runs into; The fluid that the piston 51 that wherein links to each other with piston rod 53 promotes in the inner core 31 flows in the oil storage portion 42 through through hole 21; Flow in the shoe cream room 64 through damping hole 66, fluid is when the damping hole 66 again, and the resistance of generation is used to slow down the speed that power that piston rod 53 receives produces.The speed that same principle, piston rod 54 receive the power generation is provided through the resistance that damping hole 65 produces by fluid.The speed of such two piston rods, 53,54 motions has just played the effect of damping after being slowed down.When the speed of piston rod 53,54 drops to after zero, piston rod 53,54 relies on the effect of returning springs, is returned to initial position; In the Recovery Process, the fluid in the shoe cream room 63,64 produces damping function through damping hole 65,66; Prevent that the spring answer is too fast, cause jolting of vehicle.
