Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to a high-stability automobile shock absorber compression valve seat. Background Art

[0002] Hydraulic automobile shock absorber is a device that uses liquid to transmit force to alleviate the vibration caused by uneven road surface during vehicle driving. When the vehicle is driving on a bumpy road, the spring of the suspension system will absorb the impact of the road, but the spring will quickly recover after absorbing the energy, which causes the vehicle to vibrate up and down. The role of the shock absorber is to consume and disperse the energy released by the spring in this process, prevent the vehicle from excessive bumps, and improve driving stability and comfort.

[0003] The working principle of hydraulic shock absorbers is that when the suspension system is compressed, the piston moves to compress the hydraulic oil, and the oil flows through the small hole in the valve. Due to the small hole diameter, the flow of oil will produce resistance. This resistance is the damping force, which helps slow down the rebound speed of the spring, thereby reducing the vibration of the vehicle.

[0004] With the rapid development of my country's automobile industry, people have higher and higher requirements for the driving stability and comfort of automobiles. Therefore, people have different suspension needs in different driving environments, making it impossible for traditional shock absorbers with a single damping strength to meet the diverse needs.

[0005] In view of this, a high-stability automobile shock absorber compression valve seat is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-7 .

[0030] The utility model discloses a high-stability automobile shock absorber compression valve seat, comprising a shock absorber body 1 and a hydraulic cylinder 17 arranged on one side of the shock absorber body 1 and connected through an oil pipe 16, and also comprising: an adjusting component 2, the adjusting component 2 comprising an adjusting rod 21 rotatably mounted on the hydraulic cylinder 17 and an adjusting knob 211 fixedly connected to the bottom of the adjusting rod 21, a first piston 22 fixedly connected to the adjusting rod 21, a second piston 23 rotatably connected to the bottom of the first piston 22, a first damping hole 221 opened on the first piston 22, a second damping hole 231 opened on the second piston 23, and the adjusting component 2 is used to adjust the relative position of the first piston 22 and the second piston 23 so as to adjust the size of the common through hole of the first damping hole 221 and the second damping hole 231 so as to adjust the damping; the locking component 3, the locking component 3 includes a locking rod 31, a plurality of locking grooves 32 provided on the adjusting knob 211 and a thread groove 33 provided on the bottom of the hydraulic cylinder 17, the locking rod 31 is used to penetrate the locking groove 32 and then be inserted into the thread groove 33 so as to fix the adjusting knob 211, and a locking thread 311 adapted to the thread groove 33 is provided at the position where the locking rod 31 is used to be inserted into the thread groove 33.

[0031] It should be noted that when a car encounters a bumpy situation while driving, the piston will move to compress the hydraulic oil, and the hydraulic oil will flow through the damping hole of the piston. In this process, the flow of the hydraulic oil will generate resistance, and this resistance is the damping force. The shock absorber uses this damping force to alleviate the rebound of the spring and keep the vehicle stable. In this embodiment, the first piston 22 rotates with the adjusting rod 21 to change the size of the common aperture of the first damping hole 221 and the second damping hole 231 to adjust the damping. It should be noted that the sizes of the first damping hole 221 and the second damping hole 231 are consistent, that is, when the first damping hole 221 and the second damping hole 231 coincide, the damping strength in the hydraulic cylinder 17 is the smallest, and as the first piston 22 rotates with the adjusting rod 21, the damping strength gradually increases.

[0032] Among them, the shock absorber body 1 includes an upper support 12 and a pressure cylinder 14 fixed at the bottom of the upper support 12, a piston rod 15 is slidably arranged in the pressure cylinder 14, and the bottom of the piston rod 15 is fixedly connected to the lower support 13. The upper support 12 and the lower support 13 are elastically connected by a shock-absorbing spring 11. The shock absorber body 1 is used to hydraulically deliver the oil in the pressure cylinder 14 to the hydraulic cylinder 17 when the piston rod 15 moves into the pressure cylinder 14. That is to say, when the car is bumpy, the piston rod 15 squeezes the hydraulic oil in the pressure cylinder 14 into the hydraulic cylinder 17.

[0033] Furthermore, if Figure 3As shown, a slide groove 233 is provided on the inner wall surface of the hydraulic cylinder 17, and a slider 232 is fixedly connected to the second piston 23. The slider 232 is arranged in a T shape, and the size of the slide groove 233 is adapted to the slider 232. The slider 232 is used to be slidably arranged in the slide groove 233 to ensure that the movement of the second piston 23 is linear movement. That is to say, the slider 232 and the slide groove 233 are used to prevent the second piston 23 from rotating relative to the hydraulic cylinder 17. In addition, a swivel 234 with a T-shaped cross-section is fixedly connected to the top of the second piston 23, and a rotating groove 222 matching the size of the swivel 234 is correspondingly provided at the bottom of the first piston 22. The swivel 234 and the rotating groove 222 are used to enable the first piston 22 and the second piston 23 to rotate relative to each other.

[0034] like Figure 5 and Figure 6 As shown, the first piston 22 can rotate relative to the second piston 23, while the second piston 23 and the hydraulic cylinder 17 are slidingly arranged, that is, the second piston 23 and the hydraulic cylinder 17 cannot rotate relative to each other. Therefore, when adjusting the damping, it is only necessary to rotate the adjusting rod 21 to drive the first piston 22 to rotate relative to the second piston 23. In addition, through the relative rotation arrangement of the first piston 22 and the second piston 23, when one of the two pistons moves, it will drive the other piston to move.

[0035] like Figure 3 As shown, a baffle 171 is provided at the bottom of the hydraulic cylinder 17, and a sealing ring 172 is provided at the connection position between the baffle 171 and the adjusting rod 21 to prevent oil leakage. A sealing ring 172 is provided at the connection position between the adjusting rod 21 and the bottom of the hydraulic cylinder 17 to prevent oil leakage. The baffle 171 and the two sealing rings 172 are provided to prevent the hydraulic oil in the hydraulic cylinder 17 from leaking. The sealing ring 172 can be made of silicone or fluororubber, but it should be noted that rotating the adjusting rod 21 for a long time may cause the sealing ring 172 to wear, and it needs to be checked or replaced in time during use.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
