Upper end is equipped with air reservoir, and the air reservoir upper end is connected to shoe cream room upper end, and second piston is equipped in the cylinder.
Further limit, be additionally provided with sealing element in the shoe cream room lower end, the sealing element outer wall in shoe cream room lower end
Wall is solidly connected by screw-thread fit, and the connecting rod penetrates sealing element vertically, is tightly connected and is connected between the connecting rod and sealing element
Bar can slide axially.
It further limits, the sealing element, second piston are cylinder.
It further limits, air bag is equipped in the air reservoir.
It further limits, regulating valve is equipped between the air reservoir and shoe cream room.
Using the utility model of above-mentioned technical proposal, hydraulic oil is filled in shoe cream room, first piston is set in shoe cream room, and
It is connected by connecting rod, connecting rod passes through shoe cream room lower end, and shoe cream room upper end and connecting rod lower end are respectively as installation fulcrum when installation；When
When connecting rod lower end is fast moved upwards by external force, since the oil-through hole flow on first piston is certain, first piston will be above it
Hydraulic oil it is upward, since air reservoir is arranged, and second piston is equipped in air reservoir, second piston is by air reservoir interior sealing
A confined space is formed, has the air of certain pressure in air reservoir, air reservoir upper end is connected to shoe cream room upper end, is squeezed upwards
The hydraulic oil of pressure will enter air reservoir, and hydraulic oil will push second piston, and second piston is pushed to make second piston to moving down
Dynamic, second piston will compress the air in air reservoir, which can effectively eliminate since damper is being compressed suddenly
When, instantaneously with high-speed extrusion hydraulic oil, hydraulic oil circulates since compressibility itself is poor on first piston first piston
In the case that the amount of oil-through hole is certain, the bad problem of damping effect improves damping effect；Sealing element can be vulcanie
It is made, its sealing effect between connecting rod is made to be improved；Sealing element and second piston are cylinder, improve its height, make
More stablize when it is moved axially, is not easy to deflect；Air bag is set in air reservoir, and air bag is as independent gas storage structure
Air in air reservoir will not be lost in into shoe cream room；Regulating valve is set between shoe cream room and air reservoir, and regulating valve can be adjusted
The access aperture of both sections connection, adjustment hydraulic oil circulation aperture, keeps the buffering effect of air reservoir adjustable, such as works as the big liquid in aperture
Pressure oil circulation is then reinforced by air reservoir corrective action soon, anyway adjustment effect weakens.
Compared with prior art, simple and reasonable, improvement damper damps the utility model when being compressed suddenly
Device damping effect.
Description of the drawings
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is a kind of structural schematic diagram of two-way damping-adjustable shock-absorber for four-wheel all-terrain vehicle of the utility model；
Main element symbol description is as follows：
Shoe cream room 1, oil-through hole 3, connecting rod 4, air reservoir 5, second piston 6, sealing element 7, air bag 8, is adjusted first piston 2
Valve 9.
Specific implementation mode
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
As shown in Figure 1, a kind of two-way damping-adjustable shock-absorber for four-wheel all-terrain vehicle, including shoe cream room 1, shoe cream room
1 is circular cylindrical cavity, and first piston 2 is equipped in shoe cream room 1, several oil-through holes 3 are provided on first piston 2, first piston 2 connects
There are connecting rod 4,4 one end of connecting rod to be fixedly connected with first piston 2,4 other end of connecting rod passes through 1 lower end of shoe cream room, and 1 upper end of shoe cream room is set
There are air reservoir 5,5 upper end of air reservoir to be connected to 1 upper end of shoe cream room, second piston 6 is equipped in cylinder.
