Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1:

referring to fig. 1-2, an anti-roll mechanism of a shock absorber includes a housing 1, the housing 1 is composed of two independent housings arranged in parallel, a sliding shaft 2 is arranged in one of the independent housings, a sliding block 3 connected with the sliding shaft 2 in a sliding manner is sleeved outside the sliding shaft 2, a return spring 4 is sleeved outside the sliding block 3, specifically, one end of the return spring 4 abuts against the inner wall of the independent housing, the other end of the return spring is fixedly connected with the sliding block 3, an adjusting valve seat 5 is further arranged in the independent housing, an adjusting rod is arranged in the adjusting valve seat 5, and the adjusting rod can adjust the sliding distance of the sliding block 3, so that an anti-roll adjusting function is realized; when the angle of the device installed on the vehicle is different, the effect of preventing inclination is different, when the sliding block 3 is parallel to the front-back direction of the vehicle, the effect of preventing forward inclination and backward inclination is achieved, and when the sliding block 3 is vertical to the front-back direction of the vehicle, the effect of preventing side inclination is achieved.

And a plurality of holes are formed in the sliding shaft 2 and distributed at equal intervals along the circumferential direction, and are used for guiding and dredging hydraulic oil.

Specifically, a hydraulic oil pipe is connected to the other independent shell, and is used for inputting and outputting hydraulic oil to and from the shell 1.

When the shock absorber is used, the shock absorber fixing seat is connected with a sheet metal part on an automobile chassis, the shock absorber shell 1 is connected with a suspension part on the automobile chassis, a buffer spring on an automobile is sleeved on the shell 1, and the buffer spring is connected with the fixing seat; when the automobile runs on an uneven road surface, the automobile body jolts, when the automobile runs downwards, the buffer spring is stressed to drive the automobile body to slowly run downwards, the compression stroke is at the moment, the piston rod runs upwards to drive the piston valve seat to run upwards, and a part of oil in the inner cavity of the cylinder body opens the compression valve plate and enters the part below the piston valve seat; the other part of oil flows into the oil pipe through the hole on the bottom surface of the groove in the connecting seat of the cylinder body and further flows into the cavity of the sliding block 3 through the hole on the sliding shaft 2; when the vehicle passes through a curve, the sliding block 3 is acted by centrifugal force, overcomes the elasticity of the return spring 4, and slides along the sliding shaft 2, at the moment, the sliding block 3 gradually closes the hole on the sliding shaft 2, and the compression damping of the shock absorber is increased; after the vehicle normally runs, the return spring 4 rebounds and the sliding block 3 returns.

Example 2:

on embodiment 1's basis, 3 front ends of sliding block are hemispherical, are equipped with the recess with 3 front end shape assorted of sliding block at 5 tail ends of adjusting valve seat, can avoid sliding block 3 when sliding to take place hard with adjusting valve seat 5 and collide to guarantee the safety of device.
