Description
Technical Field
[0001] This utility model relates to the field of automotive shock absorber technology, and in particular to an automotive shock absorber rocker arm adjustment device. Background Technology
[0002] Automotive shock absorbers (also known as dampers or shock absorber systems) are an important component of a car's suspension system. Their main function is to reduce and absorb the impact forces between the wheels and the road surface, maintaining a smooth ride and improving comfort and handling. The working principle of shock absorbers is to control the vertical movement of the suspension system, reducing vehicle vibration and sway, and improving vehicle stability. Shock absorbers effectively absorb vibrations caused by uneven road surfaces, preventing these vibrations from being transmitted to the vehicle body. Good shock absorbers maintain close contact between the wheels and the ground, improving vehicle handling and stability, especially during sharp turns or high-speed driving. By reducing body sway and vibration, shock absorbers enhance driving comfort. Particularly when driving on uneven roads, shock absorbers help protect the suspension system, wheels, frame, and other components by reducing vibration and impact, extending the vehicle's lifespan.
[0003] However, in existing technical solutions, the adjustment mechanism of common car shock absorbers is located in the middle of the shock absorber, inside the car tire. When the spring preload needs to be adjusted, the car needs to be lifted or the car tire needs to be removed. Then, the sliding adjustment ring connected to the thread on the outer surface of the damper is rotated by a wrench to adjust the spring travel. The operation is cumbersome, requires a lot of time and manual operation, and has low adjustment efficiency, which is a defect. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing technical solutions, the adjustment mechanism of the common automobile shock absorber is located in the middle of the shock absorber, inside the car tire. When it is necessary to adjust the spring preload, the car needs to be lifted or the car tire needs to be removed. Then, the sliding adjustment ring connected to the thread on the outer surface of the damper is rotated by a wrench to adjust the spring stroke. The operation is cumbersome, requires a lot of time and manual operation, and has low adjustment efficiency. Therefore, this utility model proposes an automobile shock absorber rocker arm adjustment device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rocker arm adjustment device for an automotive shock absorber, comprising a damper, a fixed support ring fixedly connected to the outer surface of the damper, a spring fixedly connected to the upper surface of the fixed support ring, a sliding adjustment ring fixedly connected to the upper surface of the spring, the inner wall surface of the sliding adjustment ring being sleeved on the outer surface of the damper, two limiting adjustment grooves being formed on the outer surface of the damper, limiting sliders being embedded in the inner wall surfaces of the two limiting adjustment grooves, limiting adjustment push rods fixedly connected to the upper surfaces of the two limiting adjustment push rods, and adjusting connecting rings fixedly connected to the upper ends of the two limiting adjustment push rods.
[0006] Furthermore, the upper surface of the damper is rotatably connected to a lead screw via a bearing, and the inner wall surface of the adjusting connecting ring is threadedly connected to the outer surface of the lead screw.
[0007] Furthermore, a circular knob is fixedly connected to the upper end of the lead screw, and multiple grooves are formed on the outer surface of the circular knob.
[0008] Furthermore, the plurality of grooves are equidistantly distributed.
[0009] Furthermore, a display surface is provided on one side of the lead screw, and a stroke table is provided on the outer surface of the display surface.
[0010] Furthermore, the inner wall surface of the spring is fitted onto the outer surface of the damper.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, when adjustment is required, the lead screw is rotated. The lead screw rotates inside the bearing. Driven by the thread, the adjusting connecting ring pushes two limit sliders through two limit adjusting push rods. After being subjected to force, the two limit sliders slide inside the two limit adjusting grooves. The two limit sliders and the two limit adjusting grooves cooperate to restrict the movement trajectory of the sliding adjusting ring and prevent the sliding adjusting ring from rotating after being subjected to force. After being subjected to force, the sliding adjusting ring slides on the outer surface of the damper, compressing the spring. The fixed support ring provides support force for the spring, compresses the spring stroke, and changes the spring preload. By changing the spring compression, the support strength of the shock absorber is adjusted. Adjustment can be performed without disassembling the wheel, improving adjustment efficiency.
[0013] 2. In this utility model, the lead screw is rotated by a circular knob. The circular knob increases the lever arm, saving manpower. Multiple grooves evenly increase the friction force, preventing hand slippage. By adjusting the connecting ring and the stroke gauge as a reference, the stroke of the spring can be accurately read, and the compression of the spring can be precisely adjusted. When the spring is compressed, the damper provides support force inside the spring, preventing the spring from bending and deforming under force, and ensuring the normal operation of the spring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a rocker arm adjustment device for an automobile shock absorber, including a damper 1, a fixed support ring 2 fixedly connected to the outer surface of the damper 1, a spring 3 fixedly connected to the upper surface of the fixed support ring 2, a sliding adjustment ring 4 fixedly connected to the upper surface of the spring 3, the inner wall surface of the sliding adjustment ring 4 being sleeved on the outer surface of the damper 1, two limit adjustment grooves 10 being opened on the outer surface of the damper 1, a limit slider 11 being embedded in the inner wall surface of each of the two limit adjustment grooves 10, a limit adjustment push rod 9 fixedly connected to the upper surface of the two limit adjustment push rods 11, an adjustment connecting ring 8 fixedly connected to the upper end of the two limit adjustment push rods 9, a lead screw 5 being rotatably connected to the upper surface of the damper 1 via a bearing, and the inner wall surface of the adjustment connecting ring 8 being threadedly connected to the outer surface of the lead screw 5.
[0022] In this embodiment, when adjustment is required, the lead screw 5 is rotated. The lead screw 5 rotates inside the bearing. Driven by the thread, the adjusting connecting ring 8 pushes the two limiting sliders 11 through the two limiting adjusting push rods 9. After being subjected to force, the two limiting sliders 11 slide inside the two limiting adjusting grooves 10. The two limiting sliders 11 and the two limiting adjusting grooves 10 cooperate to restrict the movement trajectory of the sliding adjusting ring 4 and prevent the sliding adjusting ring 4 from rotating after being subjected to force. After being subjected to force, the sliding adjusting ring 4 slides on the outer surface of the damper 1, compressing the spring 3. The fixed support ring 2 provides support force for the spring 3, compresses the stroke of the spring 3, and changes the preload of the spring 3. By changing the compression of the spring 3, the support strength of the shock absorber is adjusted. Adjustment can be performed without disassembling the wheel, improving adjustment efficiency. The damper 1 is a common device in daily life and is existing technology. Specific models can be selected as needed, which will not be elaborated on here.
[0023] Example 2
[0024] like Figure 1-4 As shown, a circular knob 6 is fixedly connected to the upper end of the lead screw 5. Multiple grooves 7 are provided on the outer surface of the circular knob 6. The multiple grooves 7 are distributed at equal intervals. A display surface 12 is provided on one side surface of the lead screw 5. A travel gauge 13 is provided on the outer surface of the display surface 12. The inner wall surface of the spring 3 is sleeved on the outer surface of the damper 1.
[0025] In this embodiment, the lead screw 5 is rotated by the circular knob 6, which increases the lever arm and saves manpower. Multiple grooves 7 evenly increase the friction force and prevent slippage. By adjusting the connecting ring 8 and the stroke gauge 13 as references, the stroke of the spring 3 can be accurately read, and the compression of the spring 3 can be precisely adjusted. When the spring 3 is compressed, the damper 1 provides support force inside the spring 3 to prevent the spring 3 from bending and deforming under force, thus ensuring the normal operation of the spring 3.
[0026] Working principle: such as Figure 1-4As shown, when adjustment is needed, the lead screw 5 is rotated. The lead screw 5 rotates inside the bearing, and driven by the thread, the adjusting connecting ring 8 pushes two limiting sliders 11 through two limiting adjusting push rods 9. After being subjected to force, the two limiting sliders 11 slide inside the two limiting adjusting grooves 10. The two limiting sliders 11 and the two limiting adjusting grooves 10 cooperate to restrict the movement trajectory of the sliding adjusting ring 4, preventing the sliding adjusting ring 4 from rotating after being subjected to force. After being subjected to force, the sliding adjusting ring 4 slides on the outer surface of the damper 1, compressing the spring 3. The fixed support ring 2 provides support for the spring 3. The support force is adjusted by compressing the spring 3 and changing its preload. The support strength of the shock absorber is adjusted by changing the compression of the spring 3. The screw 5 is rotated by the circular knob 6, which increases the lever arm and saves manpower. Multiple grooves 7 evenly increase the friction and prevent slippage. The stroke of the spring 3 can be accurately read by adjusting the connecting ring 8 and the stroke gauge 13 as a reference, and the compression of the spring 3 can be precisely adjusted. When the spring 3 is compressed, the damper 1 provides support force inside the spring 3 to prevent the spring 3 from bending and deforming under force, and to ensure the normal operation of the spring 3.
