Technical Field

The invention relates to a plate type oil seal shock absorber, and belongs to the technical field of shock absorbers.

Background

The common hydraulic pneumatic shock absorber is very popular with customers due to simple processing and manufacturing and higher cost performance. The common hydraulic pneumatic shock absorber has certain shock absorber oil and nitrogen gas in certain pressure inside the shock absorber due to its specific working mode. The common hydraulic pneumatic shock absorber usually adopts a horizontal oil seal and is matched with a spinning sealing machine to carry out spinning sealing, so that the inner space of the common hydraulic pneumatic shock absorber is isolated from the outer space. The horizontal oil seal is adopted for spinning sealing, and the spinning sealing of a single shock absorber needs about 30 seconds. The production efficiency needs to be improved.

Disclosure of Invention

Aiming at the defects, the invention aims to provide the plate-type oil seal which is reasonable in structure and can realize good sealing performance of the shock absorber.

The technical scheme adopted by the invention is as follows: the invention comprises an oil storage cylinder (1), a working cylinder (2) arranged on the inner side of the oil storage cylinder (1), and a piston rod (3) arranged in the working cylinder (2);

a bushing (4) is arranged between the working cylinder (2) and the piston rod (3), and a plate-type oil seal (5) located on the outer side of the bushing (4) is arranged on the piston rod (3).

And a pressing ring (6) for pressing the plate-type oil seal (5) is arranged on the inner wall of the oil storage cylinder (1).

The edge of the oil storage cylinder (1) is bent to limit the pressing ring (6), and a groove for embedding the pressing ring (6) is formed in the outer surface of the plate-type oil seal (5).

A guider (7) is arranged between the working cylinder (2) and the oil storage cylinder (1), and the guider (4) and the oil storage cylinder (1) are matched to limit the pressing ring (6).

The invention has the advantages that: in order to improve the production efficiency, the structure of the original oil seal and the guider is improved, a plate-type oil seal is developed and completed, and the sealing is carried out by matching with a four-point sealing machine; the change of the sealing mode shortens the sealing time of a single shock absorber to 12S, greatly improves the production efficiency, and meanwhile, the plate-type oil seal can be sealed by spinning by a spinning sealing machine, so that the sealing mode tends to be diversified.

The pressing ring is arranged, so that the plate-type oil seal is in closer contact with the piston rod, the sealing performance of the shock absorber is further ensured, the groove is formed in the outer surface of the plate-type oil seal, the plate-type oil seal is embedded into the groove, the position stability of the plate-type oil seal and the pressing ring is ensured, and the using performance and the using stability of the shock absorber are further ensured.

Detailed Description

The invention comprises an oil storage cylinder 1, a working cylinder 2 arranged at the inner side of the oil storage cylinder 1 and a piston rod 3 arranged in the working cylinder 2;

a bushing 4 is arranged between the working cylinder 2 and the piston rod 3, and a plate type oil seal 5 positioned on the outer side of the bushing 4 is arranged on the piston rod 3.

And a pressing ring 6 for pressing the plate-type oil seal 5 is arranged on the inner wall of the oil storage cylinder 1.

The edge of the oil storage cylinder 1 is bent to limit the pressing ring 6, and a groove for embedding the pressing ring 6 is formed in the outer surface of the plate type oil seal 5.

A guider 7 is arranged between the working cylinder 2 and the oil storage cylinder 1, and the guider 4 is matched with the oil storage cylinder 1 to limit the pressing ring 6.

The requirement of the consistency of the sealing position of the invention is as follows: the four-point sealing is so called that the oil seal is compressed by pressing four points on the oil storage cylinder to play a role in sealing oil and gas, and the consistency of the four-point height is ensured by designing the four-point sealing tool, so that the sealing effect is excellent.

The durability of the invention requires: the novel four-point sealing plate-type oil seal shock absorber is arranged on an endurance test bench for endurance test, and after the endurance test, the performance of the shock absorber is retested, so that the performance of the shock absorber is not lower than the design requirement, and the durability meets the requirement.

When the damper is used, the pressing ring 6 is embedded into the groove of the plate-type oil seal 5, and the oil storage cylinder 1 is matched with the guider 7, so that the use stability and the position stability of the pressing ring 6 are greatly improved, and the service life and the stability of the damper are ensured.
