Problems solved by technology

But because the piston and the compression valve of the shock absorber in the prior art are rigidly connected, when the piston contacts the compression valve during movement, the piston and the compression valve will wear each other, thus shortening the service life of the piston and the compression valve , In addition, when installing the shock absorber in the prior art, the two ends are generally fixed separately. During such installation, the shock absorber needs to be held by hand and is easy to install, so it is inconvenient to install, and in the shock absorber When performing shock absorption work, due to the unbalanced pressure, sometimes large and sometimes small, the impact on the joints at both ends of the shock absorber is very large, causing the joints at both ends of the shock absorber to fail under pressure, and even cause safety hazards

Embodiment 1

[0029] like figure 1 As shown, an improved shock absorber includes an oil storage cylinder 1, an outer cylinder 2 is sleeved outside the lower end of the oil storage cylinder 1, a working cylinder 3 is provided inside the oil storage cylinder 1, and a compression valve 4 is provided at the bottom of the working cylinder 3 , the upper end of the compression valve 4 is connected with a piston device, the upper end of the piston device is connected with a piston rod 5, the upper casing of the piston rod 5 is provided with a guide 6, and the top of the piston rod 5 is provided with a protective cover 7, between the guide 6 and the protective cover 7 An oil seal 8 is provided, and the piston device includes a piston 9 that cooperates with the piston rod 5. The piston 9 is provided with an accommodating cavity, and a connecting shaft 10 is arranged in the accommodating cavity, and a first elastic gasket 11 is provided outside the connecting shaft 10. , A second elastic gasket 12 is ...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the bottom side fixing device 14 includes a plate body 16 welded with the outer cylinder 2, the outer end of the plate body 16 is provided with a connecting hole 17, and the outer end of the connecting hole 17 is provided with an adsorption plate 18, the outer wall of the outer cylinder 2 is provided with at least three bottom side fixing devices 14, the adsorption plate 18 includes two waterproof layers, and a breathable layer is arranged between the two waterproof layers. When the invention is installed, it can be adsorbed on the installed part, so that the installed part and the installed part are temporarily fixed horizontally, and then connected or welded by a screw, so that there is no need to hold it during installation, and the installation operation is simple and convenient, saving physical strength.

Embodiment 3

[0033] The difference between this embodiment and Embodiment 1 is that the middle lateral fixing device 15 includes a bent plate 19 welded to the oil storage cylinder 1, and the outer end of the bent plate 19 is provided with a mounting groove 20, and the bent plate 19 is a The side is connected with an installation backing plate 21, and the outer wall of the oil storage tank 1 is provided with at least two symmetrically arranged middle side fixing devices 15. The installation backing plate 21 is connected with a transverse plate, and the transverse plate can be connected according to the shape and position of the connected parts. , reasonably set its shape and number, generally two symmetrical pieces.

Abstract

The invention relates to the technical field of automobile fittings, in particular to an improved shock absorber, which comprises an oil storage cylinder, an outer cylinder, a working cylinder, a compression valve, a piston device, a piston rod, a guider, a protecting cover and an oil seal, wherein the piston device comprises a piston with an accommodating cavity, and a connecting shaft is arranged in the accommodating cavity; a first elastic gasket is arranged on an outer sleeve of the connecting shaft; a second elastic gasket is arranged between the first elastic gasket and the compression valve; a spring is arranged between the first elastic gasket and the second elastic gasket; the outer cylinder is connected with a bottom side fixing device; and the oil storage cylinder is externally connected with a middle side fixing device. According to the invention, with the first elastic gasket, the spring and the second elastic gasket between the compression valve and the piston, mutual wear between the piston and the compression valve is avoided, and two ends of the shock absorber is protected from failure caused by compression. Besides, the outer cylinder and the oil storage cylinder are respectively connected with the bottom side fixing device and the middle side fixing device; and when being mounted, the shock absorber can be positioned through the bottom side fixing device and the middle side fixing device, so that the mounting is convenient.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to an improved shock absorber. Background technique [0002] With the rapid development of the automobile industry, especially the car industry, the shock absorber, which is an important part of the automobile, has also developed rapidly. The automobile shock absorber is a damping element and one of the important components of the automobile suspension system. , plays a decisive role in the smoothness, comfort, safety, steering operability and passability of the vehicle. The working principle of the shock absorber is that during the movement of the shock absorber piston rod, the shock absorber oil passes through the piston and The damping hole on the bottom valve seat circulates continuously, thereby converting kinetic energy into heat energy and dissipating it into the air. But because the piston and the compression valve of the shock absorber in the prior art are rig...
