Description

Technical Field

[0002] Automobile shock absorbers are very important components in automobile suspension systems. Shock absorbers are not only used in suspension in automobiles, but also in other locations. During the use of shock absorbers, a shock absorption strength adjustment device is set. However, the shock absorption strength adjustment device can only increase the shock absorption strength of the shock absorber, but cannot reduce the shock absorption strength.

[0026] A puncture-proof pad 21 is provided on one surface of the piston 2. The puncture-proof pad 21 is made of a composite of glass fiber cloth and high-strength polymer sheet. The cross-sectional shape of the piston 2 is polygonal. A polygonal oil storage chamber is provided inside the adjusting device body 1.

[0028] Example 2

[0029] See also Figure 1-4A shock absorber damping strength adjustment device comprises an adjustment device body 1, one end of which is provided with an oil nozzle 11 and an oil return pipe 13, one end of which is connected to the oil outlet end of the shock absorber cylinder through a hydraulic oil pipe, and one end of which is connected to the oil return end of the shock absorber cylinder through a hydraulic oil pipe. A piston 2 is slidably connected inside the adjustment device body 1, and the piston 2 is used to increase the difficulty of hydraulic oil entering, thereby adjusting the shock absorber's damping strength, a connecting seat 22 is provided at the center of the piston 2, and a sleeve 23 is fixedly connected to one end of the connecting seat 22, and the sleeve 23 is used to accommodate a movable rod 42, and a guide hole 24 is provided at one end of the sleeve 23, and the inner wall of the guide hole 24 is in contact with the surface of the movable rod 42, and the cross-sectional shapes of the guide hole 24 and the movable rod 42 are both polygonal, which can prevent the movable rod 42 from contacting the sleeve. The tube 23 rotates, and one end of the sleeve 23 is slidably sleeved with a movable rod 42, and the outer side of the movable rod 42 is sleeved with an adjusting spring 43. The adjusting spring 43 adjusts the supporting strength of the piston 2 by the elastic strength. One end of the adjusting spring 43 is in contact with the limiting ring 25, and the other end of the adjusting spring 43 is in contact with the supporting ring 41. One end of the movable rod 42 is fixedly connected to the adjusting rod 4, and one end of the adjusting rod 4 is connected to the adjusting sleeve 3 through a thread. The surface of the adjusting sleeve 3 is fixedly sleeved with a sealed bearing 5, and the outer ring of the sealed bearing 5 is fixedly sleeved on one end of the adjusting device body 1 to facilitate the free rotation of the adjusting sleeve 3. One end of the adjusting sleeve 3 is fixedly connected with a knob 31, and the knob 31 is convenient for the user to rotate manually. The surface of the knob 31 is fixedly inlaid with an adsorption strip 32, and the surface of the adsorption strip 32 is adsorbed and connected with an adsorption plate 51.

[0030] The adsorption plate 51 is fixedly sleeved on the outer ring surface of the sealed bearing 5. The adsorption plate 51 and the adsorption strip 32 are both made of strong magnetic material and have the function of magnetic adsorption, which is convenient for automatic positioning of the adjustment sleeve 3. A first one-way valve 12 is fixedly installed on the surface of the oil nozzle 11, and a second one-way valve 14 is fixedly installed on the surface of the return oil pipe 13 to prevent the hydraulic oil from flowing back out of the adjustment device body 1 through the oil nozzle 11, and at the same time prevent the hydraulic oil from flowing back into the adjustment device body 1 through the return oil pipe 13.

[0031] In this embodiment, by providing the sealed bearing 5, the adsorption plate 1, the knob 31 and the adsorption strip 32, the adjustment position of the adjustment sleeve 3 can be fixed by strong magnetic adsorption, thereby improving the convenience of use.

[0032] The damping strength adjustment device of the shock absorber can manually rotate the adjustment sleeve 3 clockwise when the damping strength of the shock absorber needs to be adjusted. Since the movable rod 42 connected to one end of the adjustment rod 4 cannot rotate, the adjustment rod 4 moves upward under the drive of the thread of the adjustment sleeve 3. The upward movement of the adjustment rod 4 drives the support ring 41 to squeeze the adjustment spring 43 upward, thereby increasing the elastic strength, and then improving the upward support strength of the piston 2. During the operation of the shock absorber, the hydraulic oil enters through the oil nozzle 11, and then the difficulty of pushing the piston 2 to enter the adjustment device body 1 increases, thereby increasing the damping strength of the shock absorber. If the adjustment sleeve 3 is rotated counterclockwise, the damping strength of the shock absorber is reduced. Through the set adjustment sleeve 3, adjustment rod 4, adjustment spring 43 and piston 2, not only the damping strength of the shock absorber can be improved, but also the damping strength of the shock absorber can be reduced, and the adjustment range is increased. In addition, through the set sealing bearing 5, adsorption plate 1, knob 31 and adsorption strip 32, the adjustment position of the adjustment sleeve 3 can be fixed by strong magnetic adsorption, thereby improving the convenience of use.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
