Description

Technical Field

[0001] This utility model relates to the technical field of high load-bearing shock absorber assembly, and in particular to a high load-bearing shock absorber assembly with adaptive damping adjustment. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle. When driving over uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves will still have reciprocating motion; shock absorbers are used to suppress this spring bounce.

[0003] Different shock absorbers provide different levels of support and comfort for a car. For example, if you frequently drive on uneven roads, you should choose a stiffer shock absorber for better support, while if you frequently drive on smooth roads, you should choose a softer shock absorber for better comfort. However, existing shock absorbers are usually fixed and difficult to adjust according to your needs.

[0004] Therefore, it is necessary to propose a high-load-bearing shock absorber assembly with adaptive damping adjustment to solve the above problems. Utility Model Content

[0022] This utility model provides, for example Figures 1-4The diagram illustrates a high-load-bearing shock absorber assembly with adaptive damping adjustment. It includes a cylinder 1 with an internal oil chamber 2 filled with oil. A piston rod 3 is slidably mounted inside the oil chamber 2, extending through the top of the cylinder 1. An adjusting cylinder 15 is located outside the cylinder 1. A piston block 10 is slidably mounted inside the adjusting cylinder 15, dividing the interior of the adjusting cylinder 15 into an oil chamber 11 and an air chamber 12. The air chamber 12 is located above the oil chamber 11. The oil chamber 11 and the oil chamber 2 are connected by a connecting component, which includes a base 7 and a conveying channel 9. One end of the base 7 is fixedly connected to the bottom end of the cylinder 1, and the other end is fixedly connected to the bottom end of the adjusting cylinder 15. The conveying channel 9 is located inside the base 7, with one end connected to the oil chamber 2 and the other end connected to the oil chamber 11. The cylinder 1, piston rod 3, base 7, and adjusting cylinder 15 together form a damping element.

[0023] When the piston rod 3 retracts into the oil chamber 2, it will push the oil inside the oil chamber 2 into the oil cavity 11 through the conveying channel 9, and push the piston block 10 to slide upward inside the regulating cylinder 15.

[0024] Furthermore, the hydraulic cylinder 1, the base 7, and the adjusting cylinder 15 are arranged in a U-shape.

[0025] An elastic assembly is provided on the outside of the hydraulic cylinder 1. The elastic assembly includes a fixed plate 4, a top seat 5, and a spring 6. The fixed plate 4 is fixedly connected to the outer wall of the hydraulic cylinder 1, the top seat 5 is fixedly connected to the top of the piston rod 3, and the spring 6 is fitted onto the outside of the hydraulic cylinder 1. One end of the spring 6 is fixedly connected to the top of the fixed plate 4, and the other end of the spring 6 is fixedly connected to the bottom of the top seat 5. When the piston rod 3 retracts into the oil chamber 2, the spring 6 contracts; and the spring 6 assists the piston rod 3 in returning to its original position.

[0026] To achieve adaptive adjustment, an air pipe 13 is connected to the top of the regulating cylinder 15, and a solenoid valve 14 is installed on the air pipe 13. A pressure sensor 8 is installed on the top of the air chamber 12. In actual use, a power supply device can be installed outside the regulating cylinder 15 to power the pressure sensor 8 and the solenoid valve 14. The power supply device includes a battery and other structures. The power supply device is a common existing technology and will not be described in detail here.

[0027] Specifically, a controller can be configured to connect between the solenoid valve 14 and the pressure sensor 8. The controller and its control principle are common existing technologies and will not be elaborated here.

[0028] When piston rod 3 retracts into oil chamber 2, it forces the oil inside oil chamber 2 into oil cavity 11 through delivery channel 9, and pushes piston block 10 upward inside adjusting cylinder 15. This causes gas inside air cavity 12 to be discharged through air pipe 13. Pressure sensor 8 monitors the pressure inside air cavity 12 and transmits the information to controller, which controls the opening and closing degree of solenoid valve 14. For example, when driving on uneven roads, solenoid valve 14 opens less, resulting in a smaller instantaneous flow of gas through air pipe 13. Piston block 10 slides slower, pressure sensor 8 detects higher pressure, and the shock absorber is stiffer overall, providing better support. When driving on smooth roads, solenoid valve 14 opens more, resulting in a larger instantaneous flow of gas through air pipe 13. Piston block 10 slides faster, pressure sensor 8 detects lower pressure, and the shock absorber is softer overall, providing better comfort, thus achieving an adaptive effect.

[0029] In addition, the pressure sensor 8 can be used in conjunction with the vehicle's bump monitoring system, such as an acceleration sensor, meaning that when the ride is bumpy, a higher pressure is required inside the air chamber 12.

[0030] This utility model, by setting up structures such as air chamber 12 and air pipe 13, allows for flexible adjustment of the shock absorber's operating state, achieving an adaptive effect and improving the efficiency of the high-load shock absorber assembly.

[0031] Furthermore, this shock absorber is particularly suitable for small vehicles such as motorcycles, as it is designed for appropriate load-bearing capacity.

[0032] To improve the sealing between the piston rod 3 and the oil chamber 2, a sealing sleeve 16 is installed at the bottom of the piston rod 3, and the sealing sleeve 16 is attached to the inner wall of the oil chamber 2.

[0033] Considering that the sealing sleeve 16 is prone to wear during the use of the shock absorber, an expansion chamber 17 is provided inside the sealing sleeve 16. The expansion chamber 17 surrounds the outside of the piston rod 3. A compression chamber 18 is also provided inside the sealing sleeve 16, located at the bottom end of the sealing sleeve 16. The expansion chamber 17 and the compression chamber 18 are connected. When the piston rod 3 retracts into the oil chamber 2, the bottom end of the sealing sleeve 16 is concave upward under the pressure of the oil, and the compression chamber 18 contracts. The gas inside the compression chamber 18 enters the interior of the expansion chamber 17. Even if the exterior of the sealing sleeve 16 is worn, the expansion chamber 17 can expand and fit against the inner wall of the oil chamber 2, ensuring stable compression of the oil by the piston rod 3 and improving the load-bearing capacity.

[0034] In addition, in actual use, a sealing ring can be set on the piston rod 3. The sealing ring is located above the sealing sleeve 16. The sealing ring and the sealing sleeve 16 cooperate to ensure the sealing effect. It can be adjusted according to the specific use.
