Background

With the development of the times, automobiles become an indispensable part in life, but the debugging and matching of automobile performance is an important work in the whole automobile development process, and the shock absorber needs to be made into a detachable (adjustable) shock absorber (hereinafter referred to as an adjustable shock absorber) in the debugging and matching process so as to adjust and combine valve train parts.

In the prior art, a section of threaded cylinder is directly welded on an oil storage cylinder, then a proper threaded cover is matched according to the size of the threaded cylinder, and then the threaded cylinder is covered by the threaded cover to form the adjustable shock absorber.

The prior art at least has the following technical problems:

1. the end face dimension of adjustable bumper shock absorber is bigger than the end face dimension of quantitative product bumper shock absorber, and the dust cover can not normally be installed when the debugging matches, causes that adjustable bumper shock absorber cleanliness is poor.

2. The end face shape and the area of the adjustable shock absorber are greatly different from those of a mass production shock absorber, and the buffer blocks are different on the contact surfaces of the adjustable shock absorber and the mass production shock absorber, so that the performance difference is caused when the mass production shock absorber is introduced to debug and match the selected buffer blocks.

3. The torque when the screw cap is screwed down cannot be measured, and the screwing parameters of the screw cap cannot be fixed and quantized.

Disclosure of Invention

The invention provides an adjustable shock absorber, aiming at the problems that the cleanliness of an adjustable shock absorber is poor due to the fact that a dust cover cannot be normally installed during debugging and matching, a buffer block selected during debugging and matching causes performance difference when mass production is introduced for use, torque cannot be measured during screwing of a threaded cover, and screwing parameters of the threaded cover cannot be fixed and quantized in the prior art, and the adjustable shock absorber comprises the following components: through the internal thread screw tube, the screw cap is screwed into the screw tube, so that the size of the end face of the adjustable shock absorber is ensured not to influence the subsequent process.

In order to achieve the purpose, the invention adopts the technical scheme that: the adjustable shock absorber comprises a shock absorber body and a threaded cylinder, wherein the outer wall of the end portion of the shock absorber body is connected with the inner wall of the threaded cylinder, and the other end of the threaded cylinder is connected with a threaded cover.

Preferably, the invention further comprises an oil seal gasket, wherein the oil seal gasket is arranged between the threaded cover and the shock absorber.

Preferably, the threaded cylinder is provided with an oil seal for placing an oil seal gasket.

Preferably, the threaded cylinder is provided with a step platform for fixing the relative position of the threaded cylinder and the outer cylinder of the shock absorber.

Preferably, the end face of the step platform is a straight line, and the formed notch is used for placing an oil seal gasket.

Preferably, the shock absorber is fixedly connected with the threaded cylinder through welding.

Preferably, the inner wall of the threaded cylinder is provided with threads, and the outer wall of the threaded cover is provided with threads matched with the threaded cylinder, so that the threaded cover can be screwed into the threaded cylinder.

Preferably, the threaded cover is provided with a plurality of tool holes for fixing the tightening torque.

Preferably, the number of the tool holes is 4.

Preferably, the end face of the threaded cap is the same as that of a mass production shock absorber.

Compared with the prior art, the technical scheme of the invention has the following advantages/beneficial effects:

1. the threaded cover is arranged in the threaded cylinder, so that the installation of the dust cover is not influenced.

2. According to the invention, the end face is more consistent with the end face of the mass production shock absorber due to the built-in threaded cover, and performance change cannot be caused when the mass production of the selected buffer block is introduced by debugging and matching.

3. The screw cap is provided with a tool hole, and the screw cap can be matched with a special tool to fix the screwing torque when being screwed down.
