Description
Technical field
The present invention relates to vibration damper technical field, especially a kind of automobile absorber high stability piston structure.
Background technique
Vibration damper, being the decay for accelerating vehicle frame and body vibrations, to improve the utensil of ride of vehicle (travelling comfort), in the suspension system inside of most of automobile, vibration damper being housed.Vibration damper is an important spare part on automobile, and the quality of its performance directly has influence on the travelling comfort of automobile, control stability and Security.In prior art, conventional hydraulic damper, its complex structure, control stability is poor, does not reach desirable damping effect.In addition, conventional vibration damper uses pot type piston, and in use, its oil pressure is unstable, causes poor damping effect.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of automobile absorber high stability piston structure rational in infrastructure, thus improves control stability, good damping effect.
The technical solution adopted in the present invention is as follows:
A kind of automobile absorber high stability piston structure, comprise cylinder body, be provided with piston in described cylinder body, described internal piston is inserted with push rod, on described push rod, cover has the first spring, and the rear end of described first spring is fixed on the afterbody of cylinder body by screw and O shape circle; Also be provided with piston rod in described cylinder body, described piston rod becomes T-shaped structure, and described piston rod head end surface abuts with push rod, and described piston rod afterbody is provided with the second cylinder cap, and Capsule is installed in described second cylinder cap outer end; Described piston becomes cylindrical structure, the outer peripheral surface of described piston has screw thread oil groove; Gap is left between the outer peripheral surface of described piston and the inner peripheral surface of cylinder body.
Further improvement as technique scheme:
The structure of described push rod is: comprise push rod body, and described push rod body is provided with door, and described door one end is provided with packing ring;
The outer peripheral surface of described cylinder body has worm structure.
Beneficial effect of the present invention is as follows:
Compact structure of the present invention, rationally, the design of outside piston side face screw thread oil groove, can make it in use have the change of more stable oil pressure, thus ensure that the stability that vibration damper uses; Substantially increase the overall performance of vibration damper, stable working is high, improves control stability, good damping effect.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the automobile absorber high stability piston structure of the present embodiment, comprise cylinder body 1, piston 7 is installed in cylinder body 1, piston 7 inside is inserted with push rod 14, on push rod 14, cover has the rear end of the first spring 6, first spring 6 to be fixed on the afterbody of cylinder body 1 by screw 5 and O shape circle 13; Also be provided with piston rod 2 in cylinder body 1, the T-shaped structure of 2 one-tenth, piston rod, piston rod 2 head end abuts with push rod 14, and piston rod 2 afterbody is provided with the second cylinder cap 3, second cylinder cap 3 outer end and installs Capsule 4; As shown in Figure 4,7 one-tenth, piston cylindrical structure, the outer peripheral surface of piston 7 has screw thread oil groove 701; Gap is left between the outer peripheral surface of piston 7 and the inner peripheral surface of cylinder body 1.
As shown in Figure 5, the structure of push rod 14 is: comprise push rod body 1401, push rod body 1401 is provided with door 1402, and door 1402 one end is provided with packing ring 1403.
As shown in Figure 1, the outer peripheral surface of cylinder body 1 has worm structure.
As shown in Figure 3, the mounting structure of piston rod 2 is: piston rod 2 is provided with energy-absorbing piston 11 by star circle 15, between the left side of energy-absorbing piston 11 and piston rod 2 head, the first cylinder cap 8 is installed, energy-absorbing piston 11 is also provided with stuffing box gland 10 and the first Steel Cable Baffle Ring 9; The piston rod 2 being positioned at cylinder body 1 head is provided with cylinder cap 16, and cylinder cap 16 is fixed in cylinder body 1 by the second Steel Cable Baffle Ring 17, installs the second spring 12 between energy-absorbing piston 11 right-hand member and cylinder cap 16.
In actual using process, power actuated plunger bar 2 is moved to the left, piston rod 2 head abuts with push rod 14 and compresses, promote piston 7 to be under force moved to the left, now the first spring 6 compresses, in the raw extruding of the fry dried food ingredients of piston 7 left end inner chamber part, due to the design of piston 7 screw thread oil groove 701, now oil flows through piston 7 outer ring along screw thread oil groove 701, and oil order enters the oilhole of the first cylinder cap 8, compresses energy-absorbing piston 11, simultaneously, oil enters in stuffing box gland 10, thus promotion energy-absorbing piston 11 moves right, and extrudes the second spring 12.When piston rod 2 moves right, the first spring 6 and the second spring 12 reset.Thus reach the effect of damping.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
