Fig. 2 is the fundamental diagram (separate unit) of the automatically reset oil gas adjustable damping of a kind of ability device;
Fig. 3 is the fundamental diagram (three) of the automatically reset oil gas adjustable damping of a kind of ability device.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the automatically reset oil gas adjustable damping of a kind of ability device of the utility model is done further to describe.
Shown in accompanying drawing 1, the automatically reset oil gas adjustable damping of a kind of ability device comprises cylinder barrel 7; Said cylinder barrel 7 upper ends are provided with front cover 3; Said cylinder barrel 7 lower ends connect tail pipe 11 through middle end cap 10, and said tail pipe 11 lower ends are provided with earrings 14, and front cover 3, cylinder barrel 7, middle end cap 10 and tail pipe 11 set inside have piston rod 2; Be provided with Sealing 8 between said piston rod 2 and the cylinder barrel 7; Said Sealing 8 is divided into upper and lower two chambeies with cylinder barrel 7, and these upper and lower two chambeies communicate through the damping mechanism that is provided with on cylinder barrel 7 outer walls, and said tail pipe 11 lower ends are communicated with air supply pipe 13 through gas-tpe fitting 12.
Piston rod 2 tops are provided with ball pivot 1.
Be provided with Sealing 4 between front cover 3 and the piston rod 2.
Damping mechanism comprises the oil connection 5 and damping modulating valve 9 that is arranged at respectively on cylinder barrel 7 upper and lower two cavity outer walls, links to each other through cross over pipe 6 between said oil connection 5 and the damping modulating valve 9.
Shown in accompanying drawing 2, the automatically reset oil gas adjustable damping of a kind of ability device of the utility model, oil pressure chamber A15, oil pressure chamber B16 are full of fluid, and atmospheric pressure cavity C17 feeds pressurized air.During original state, under compressed-air actuated effect, the outside motion of piston rod is stretched out entirely, and the fluid in the A15 of oil pressure chamber flows to oil pressure chamber B16 through the damping modulating valve.Act on the anterior ball pivot of piston rod as external force, when active force that active force produces greater than air pressure, the piston rod withdrawal, the fluid in the B16 of oil pressure chamber flows to oil pressure chamber A15 through throttle valve.When acting on the active force that the anterior active force of piston rod produces less than air pressure, piston rod stretches out under gas pressure automatically, and the fluid in the A15 of oil pressure chamber flows to oil pressure chamber B16 through throttle valve.Because fluid receives throttling and can not pass through rapidly when flowing through the damping modulating valve, thereby makes the motion of piston rod receive damping, can not rapid movement.Change the openings of sizes of damping modulating valve, can change throttling speed, realize changing damping characteristic, reach the purpose that changes damping.
Shown in accompanying drawing 3, when two or many same models can automatically reset oil gas adjustable damping devices use simultaneously, the oil pressure chamber A15 of the automatically reset oil gas adjustable damping of an ability device is linked to each other with another oil pressure chamber B16 ' through the damping modulating valve.When the piston rod movement of the automatically reset oil gas adjustable damping of an ability device, the fluid of its oil pressure chamber A15 just flows to the automatically reset oil gas adjustable damping of another ability device oil pressure chamber B16 '.Since two (or many) can automatically reset oil gas adjustable damping device structural parameter identical, flow between the damping oil cylinder and the fluid that flows out equates, so just guaranteed being synchronized with the movement of many ability automatically reset oil gas adjustable damping device piston rods.
Above-described embodiment, the utility model embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technological scheme scope and replacement all should be included in the protection domain of the utility model.
