Description

Technical Field

[0001] This patent relates to the technical field of shock absorbers, specifically a shock absorber with adjustable damping. Background Art

[0002] In the automobile suspension system, since the elastic element itself will have reciprocating motion when filtering the road vibration, in order to improve the smoothness of the car's driving, shock absorbers are usually installed in the suspension system to suppress the shock when the spring rebounds after absorbing the shock. The damping spring shock absorber has a wide load range, which is convenient for users to choose;

[0003] In order to make the vehicle suspension reach a better state, damping adjustable shock absorbers came into being. However, commercially available damping adjustable shock absorbers usually have a damping adjustment knob at the bottom of the cylinder and are exposed to the outside. At the same time, when the vehicle passes through a wading section, the splashed water will fall on the shock absorber, which can easily cause the damping adjustment knob to rust and make it impossible to adjust. Utility Model Content

[0027] Because the protective cover 6 is slidably installed in the slide groove 5 through the connecting block 7, the protective cover 6 cannot rotate. When the positioning rod 83 in the positioning mechanism 8 is inserted into the slot 9 outside the damping adjustment knob 4, the positioning rod 83 will position the damping adjustment knob 4 to prevent the damping adjustment knob 4 from rotating autonomously.

[0028] Specifically, the positioning mechanism 8 includes a support plate 81, a through hole 82, a positioning rod 83 and a locking bolt 84. The inner side wall of the protective cover 6 is provided with a support plate 81, the support plate 81 is annular, the upper wall of the support plate 81 is provided with a through hole 82, the positioning rod 83 is inserted and installed in the through hole 82, the positioning rod 83 can slide in the through hole 82, the side wall of the protective cover 6 is provided with a threaded hole 10, the locking bolt 84 is screwed into and installed in the threaded hole 10, and the locking bolt 84 can fit with the side wall of the shock absorber body 1;

[0029] The position of the protective cover 6 can be fixed by tightening the locking screw 84 .

[0030] Specifically, a closing mechanism 11 is installed on the inner side wall of the protective cover 6, and the closing mechanism 11 can close the lower wall of the protective cover 6.

The rubber sleeve 111 is sleeved on the outer side of the protective cover 6, and the side wall of the shock absorber body 1 is provided with a mounting groove 113. The sealing ring 112 is sleeved on the outside of the shock absorber body 1, and the sealing ring 112 is arranged in the mounting groove 113. The sealing ring 112 can fit the side wall of the rubber sleeve 111;

[0031] Under the action of the closing mechanism 11, the protective cover 6 is in a closed state, which prevents the entry of external water or dust, prevents the damping adjustment knob 4 from being unable to rotate, and prevents the device from having an unadjustable damping.

[0032] Specifically, a shock absorber spring 12 is sleeved on the outside of the shock absorber body 1 .

[0033] Specifically, a rubber pad 13 is installed at one end of the locking bolt 84 located inside the protective cover 6, and the rubber pad 13 can fit with the side wall of the shock absorber body 1;

[0034] The rubber pad 13 can be provided to prevent the locking bolt 84 from scratching the coating on the outside of the shock absorber body 1 after being tightened, thereby preventing the outer wall of the shock absorber body 1 from rusting.

[0035] Specifically, a limit ring 14 is installed on the upper wall of the positioning rod 83, and the limit ring 14 is located above the support plate 81;

[0037] Working principle: When the staff needs to adjust the damping of the shock absorber body 1, they can clamp the outside of the damping adjustment knob 4 with an external wrench, and then adjust the damping size of the shock absorber body 1 by turning the damping adjustment knob 4. After the adjustment is completed, slide the protective cover 6 downward so that it is connected to the outside of the damping adjustment knob 4 to protect the damping adjustment knob 4. After the cover is connected, the positioning rod 83 in the positioning mechanism 8 will be inserted into the slot 9 on the outside of the damping adjustment knob 4, and the positioning rod 83 will position the damping adjustment knob 4 to prevent the damping adjustment knob 4 from rotating autonomously. Then the locking bolt 84 needs to be tightened to fix the position of the protective cover 6.
