Description

Technical Field

[0001] The utility model relates to the field of shock absorbers, in particular to a sealed reinforced connecting part structure and a shock absorber. Background Art

[0002] Some modern shock absorbers feature an electronically controlled valve assembly, typically connected to the shock absorber's intermediate cylinder and oil reservoir, to dynamically adjust the shock absorber's damping characteristics by adjusting the flow rate of the valve. For example, a three-chamber shock absorber with application number 201621148277.X is available.

[0003] When installing an electric control valve assembly, it is necessary to ensure the sealing between the intermediate oil cylinder and the oil storage tank in the shock absorber. Existing connecting sealing parts are usually metal parts and O-rings. The connection positions where the connecting sealing parts are located are all metal. For example, the connection positions between the connecting sealing parts and the intermediate cylinder and the oil storage tank, as well as the contact positions between the connecting sealing parts and other components in the shock absorber are usually metal. If the connecting sealing parts are not installed properly or the ports of the connecting parts are not processed well, the metal components at the connection positions can easily damage and scratch the sealing surface of the O-ring connecting sealing parts, affecting the sealing between the connecting sealing parts and the surrounding components, resulting in substandard sealing and a high scrap rate. Therefore, improving a seal-reinforced connecting part structure can make installation more convenient and improve production efficiency. Summary of the Invention

[0007] The rubber layer is arranged on the surface of the plane sealing base and covers at least the inner and outer surfaces of the radial sealing cylinder and the upper surface of the plane sealing base.

[0008] Preferably, the rubber layer is vulcanized and attached to the outer layer of the seal base.

[0009] Preferably, a wave groove is provided on the outer ring of the bottom side of the rubber layer.

[0010] Preferably, at least one convex ring is provided on the upper portion of the rubber layer.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] Example 1

[0024] like Figure 1 、 2 The seal-enhanced connecting component structure 1 shown is composed of a planar seal base 11 and a radial seal cylinder 12 , and has a structure with a base and a connecting cylinder.

[0025] The flat seal base 11 is made of metal. The upper end of the radial seal cylinder 12 is connected to the middle of the flat seal base. The radial seal cylinder 12 and the flat seal base are an integrated structure.

[0026] The rubber layer 13 is provided on the surface of the planar seal base 11 and covers at least the inner and outer surfaces of the radial sealing cylinder 12 and the upper surface of the planar seal base.

[0027] In this embodiment, the rubber layer 13 is vulcanized and attached to the outer layer of the seal base.

[0028] In this embodiment, a wave groove 14 is provided on the outer ring of the bottom side of the rubber layer 13, which has a wave-like surface shape, and improves the sealing performance during sleeve installation.

[0029] In this embodiment, a convex ring 15 is provided on the upper portion of the rubber layer 13. When installed, the upper portion of the rubber layer 13 is compressed and deformed, thereby improving the sealing performance.

[0030] In this embodiment, at least one hollow groove 16 is provided on the upper portion of the rubber layer 13. In this embodiment, the hollow grooves 16 are four evenly arranged arc-shaped ring structures, and are through grooves passing through the flat seal base 11.

[0031] Example 2

[0032] like Figure 3 The shock absorber shown in Figure 4 consists of a shock absorber body and an electronically controlled valve assembly 2. Typically, a three-chamber shock absorber comprises a working chamber, an intermediate chamber, and an oil storage chamber, formed from the inside out by an oil storage barrel 4, an intermediate cylinder 5, and a working cylinder 6, respectively. A piston assembly 9 is located within the working chamber, and a working component is installed between the end of the piston rod assembly and the outer end of the oil storage chamber to achieve a shock-absorbing effect.

[0033] The seal-reinforced connection component structure 1 in Example 1 is installed between the electronically controlled valve assembly 2 and the shock absorber body.

[0034] The radial sealing sleeve 12 of the seal-reinforced connection component penetrates the shock absorber's oil reservoir 4 and intermediate cylinder 5. The intermediate cylinder 5 is equipped with a mounting valve port 51 that seals against the radial sealing sleeve 12. The seal-reinforced connection component serves as a height limiter and support for the electrically controlled valve assembly 2. The wavy rubber surface creates an interference fit with the intermediate cylinder 5, ensuring a tight seal during installation and preventing scratches on the front rubber during installation, which could lead to seal failure. The wavy surface of the seal-reinforced connection component also ensures that the seal remains intact even if the components tilt.

[0035] The flat sealing base of the seal-reinforced connecting part is arranged in the electric control valve assembly 2 , and the electric control valve support seat 3 is fixedly installed on the outer edge of the oil storage cylinder 4 .

[0036] In this embodiment, the planar sealing base of the sealing-reinforced connecting part is located in the electric control valve support seat 3 of the electric control valve assembly 2. The electric control valve support seat 3 and the oil storage cylinder 4 are fixed by welding. The bottom of the electric control valve support seat 3 has an opening through which the radial sealing cylinder 12 can pass, and an O-type sealing gasket 7 is arranged in the opening. The O-type sealing gasket 7 is tightly attached to the lower surface of the planar sealing base. A locking nut 8 is also installed on the upper part of the electric control valve support seat 3. The locking nut 8 presses the electric control valve assembly 2 and the sealing-reinforced connecting part together.

[0037] Among them, the radial sealing cylinder 12 and the hollow groove 16 of the sealing reinforced connecting part connect the intermediate cavity and the oil storage cavity, and the size of the damping hole is adjusted through the electronically controlled valve assembly 2 to control the oil flow and adjust the damping force of the shock absorber.

[0038] Among them, the upper inner periphery of the locking nut 8 is a narrow structure. When locked, the electric control valve assembly 2 is pressed tightly into the electric control valve support seat 3, so that the electric control valve assembly 2 is pressed tightly against the seal-reinforced connecting part.

[0039] The seal-reinforced connecting part structure and shock absorber described in the utility model, the wavy surface of the seal-reinforced connecting part not only serves as a sealing surface to prevent the front end rubber from being scratched and the sealing surface from failing during installation, but also acts as an elastomer support to ensure vertical installation and tight connection of the middle cylinder, which can greatly reduce the seal failure state during installation, improve safety efficiency, reduce seal leakage, and greatly increase the service life of the shock absorber.

[0040] The seal-reinforced connection features a corrugated rubber vulcanized onto a metal frame, minimizing displacement of the rubber during installation. The surface structure increases contact between the sealing surfaces at the installation location, preventing scratches on the front rubber and potential seal failure. The remaining corrugated rubber subsequently enhances the seal and reduces leakage. This replaces the traditional metal connection method, which uses a combination of metal parts and O-rings, thus avoiding the problem of scratches and damage to the sealing surface, which can affect sealing performance.

[0041] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
