Technical Field

The present invention relates to a shock absorber.

Background

In the existing shock absorber, or separate mechanical shock absorption is adopted, such as installing a shock absorption spring; or damping material is independently adopted to achieve damping, such as damping rubber; or damping grease alone can be used to achieve damping, such as damping grease dampers. However, no matter what damping mode is adopted, single damping is adopted, and under the condition of meeting the vibration condition that the vibration is more severe or the condition is more complex, if an independent damping unit is damaged or loses damping efficiency, the whole damper is equal to the damping loss effect, so that the equipment or unit needing damping is greatly influenced.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the defects of the prior art, and provides the shock absorber integrating shock absorption rubber and compound damping grease for shock absorption.

The damping oil filling device comprises a bottom cover, an outer wall cylinder and a deformation surface cover, wherein the outer wall cylinder is hollow, two ends of the outer wall cylinder are opened, the bottom cover is arranged at one end of the outer wall cylinder in a sealing mode, the deformation surface cover is arranged at the other end of the outer wall cylinder in a sealing mode, and compound damping oil is filled among the bottom cover, the outer wall cylinder and the deformation surface cover.

Further, the deformation surface cover is made of elastic rubber.

Further, the components of the compound damping grease comprise a composition of dimethyl silicone oil, modified silicone oil, a liquid hydrocarbon mixture and a filler.

Furthermore, the components of the compound damping grease comprise, by weight, 50-90 parts of dimethyl silicone oil, 0.5-5 parts of modified silicone oil, 0.5-5 parts of liquid hydrocarbon mixture and 5-50 parts of filler.

Preferably, the components of the compound damping grease comprise, by weight, dimethyl silicone oil 75, modified silicone oil 3, liquid hydrocarbon mixture 3 and filler 19.

Further, the bottom cap is ultrasonically welded to an end of the outer wall cylinder.

The invention has the beneficial effects that: the invention adopts the deformable surface cover made of elastic rubber and the compounded damping grease as the damping unit, and can effectively deal with the damping condition of different damping environments. The compound damping grease is used as a damping medium, so that the shock absorption of the shock absorber is better and softer compared with the shock absorber in the prior art, and the shock absorber is not limited by the mechanical life of the damping medium, so that the shock absorption aging is greatly increased; when the composite damping grease is subjected to larger pressure caused by external larger vibration, the deformation surface cover made of the elastic rubber material can enable the compression deformation of the elastic rubber material to absorb the pressure generated by partial vibration, and the effect of buffering and damping at the first section is achieved, so that the damping pressure of the composite damping grease is reduced, and the overall damping effect and the damping service life of the composite damping grease are effectively improved.

Detailed Description

As shown in fig. 1, the damping oil-filled container comprises a bottom cover 1, an outer wall cylinder 2 and a deformable surface cover 3, wherein the outer wall cylinder 2 is hollow, two ends of the outer wall cylinder are open, the bottom cover 1 is hermetically arranged at one end of the outer wall cylinder 2, the deformable surface cover 3 is hermetically arranged at the other end of the outer wall cylinder 2, and compound damping oil is filled among the bottom cover 1, the outer wall cylinder 2 and the deformable surface cover 3.

The deformable surface cover 3 is made of elastic rubber.

The components of the compound damping grease comprise a composition of dimethyl silicone oil, modified silicone oil, a liquid hydrocarbon mixture and a filler. The compound damping grease is added with the modified silicone oil and the liquid hydrocarbon mixture on the basis of the dimethyl silicone oil, so that the damping value of the compound damping grease is less changed along with the change of temperature, and meanwhile, the compound damping grease is added with the filler, so that the compound damping grease is lower in cost compared with the damping grease of pure silicone oil.

The components of the compound damping grease comprise, by weight, 50-90 parts of dimethyl silicone oil, 0.5-5 parts of modified silicone oil, 0.5-5 parts of liquid hydrocarbon mixture and 5-50 parts of filler.

The components of the compound damping grease comprise, by weight, 75 parts of dimethyl silicone oil, 3 parts of modified silicone oil, 3 parts of liquid hydrocarbon mixture and 19 parts of filler. The filler includes, but is not limited to, calcium carbonate, white carbon black, diatomaceous earth, kaolin, montmorillonite and glass microspheres.

The bottom cap 1 is ultrasonically welded to one end of the outer wall cylinder 2.

In the present invention, the shape of the deformable surface cover 3 includes, but is not limited to, a rectangular soft gel, a conical soft gel, a circular soft gel, and the like.

In this embodiment, the deformable surface cover 3 is a conical soft colloid.

When the shock absorption bottom cover works, the bottom cover 1 is fixedly arranged outside a part needing shock absorption, and the deformation surface cover 3 is in contact with an external shock surface. When receiving outside vibrations influence, deformation face lid 3 self is earlier through the external force that material compression deformation absorbed the partial vibrations and brought, then the holistic tensile deformation of rethread, wholly become sunken disk by the toper promptly, reaches all the other vibrations external force compound damping grease, promptly deformation of deformation face lid 3 drives compound damping grease is compressed, compound damping grease absorbs and offsets the shock pressure at the in-process of compressed to for needing the shock attenuation part to offset vibrations, reach the shock attenuation effect.

The invention is suitable for the field of shock absorbers.
