Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an oil-draining type side damping adjustable shock absorber. Background Art

[0002] During driving, automobile suspension systems are generally equipped with shock absorbers to rapidly dampen vibrations between the frame and body, improving ride smoothness and comfort. During daily driving, appropriate shock absorbers should be used according to the road conditions. This not only significantly improves ride comfort but also effectively extends the shock absorber's service life. Cartridge shock absorbers are popular among customers for their simple structure, ease of manufacturing, and high cost-effectiveness. Cartridge shock absorbers typically utilize a combination of a restoring valve system and a compression valve system. When the piston moves to the left, oil in the working cylinder at the left end of the piston passes through the restoring valve system, causing the valve disc to deform and generate damping force. When the piston moves to the right, oil in the working cylinder at the right end of the piston passes through the compression valve system, causing the valve disc to deform and generate damping force. However, this structure has certain limitations. The valve system's single damping force makes it difficult to adapt to varying road conditions, significantly affecting ride comfort.

[0003] In the prior art, the flow rate of the oil leakage is controlled by providing a plurality of oil leakage holes with different diameters on the regulating valve core and adjusting the positions of the oil leakage holes.

[0004] However, when the existing regulating valve core is used, each oil drain hole needs to be drilled separately during processing, which requires multiple clamping and replacement of different drill bits, making the processing more complicated. Utility Model Content

An oil guide pipe 16 is provided on the inner side of the oil reservoir 13, and the oil guide pipe 16 is arranged along the inner surface of the oil reservoir 13. A regulating valve seat 1 is provided on the top of the oil reservoir 13, and an adjustable valve core is provided in the inner cavity of the regulating valve seat 1.

[0025] The adjustable valve core includes a regulating valve core 2 rotatably mounted on a regulating valve seat 1, an oil drain groove 5 is provided on the outer side of the regulating valve core 2, and the oil drain groove 5 is arranged from shallow to deep from one end to the other end, and an opening 6 is provided at the deepest part of the oil drain groove 5, and the opening 6 is communicated with the inner cavity of the regulating valve core 2;

[0026] One end of the oil guide pipe 16 passes through the regulating valve seat 1 and is connected to the oil drain groove 5 .

[0027] When adjusting the oil leakage flow rate, the oil leakage groove 5 can be driven to rotate by rotating the regulating valve core 2, and the position of the oil guide pipe 16 connected to the oil leakage groove 5 can be changed during the rotation. Since the oil leakage groove 5 is arranged from shallow to deep, the effect of adjusting the oil leakage flow rate can be achieved. Compared with the existing technology, the present device does not need to be clamped multiple times and different drill bits are replaced during processing. Only one time is needed to complete the processing, thereby increasing the processing efficiency and solving the problem that the existing technology requires multiple clamping and replacement of different drill bits, which makes the processing more cumbersome.

[0028] Furthermore, a gear knob 9 is provided at the top of the regulating valve core 2, and the gear knob 9 is detachably mounted on the top of the regulating valve core 2 by a bolt 7, and a cap 8 is movably provided above the bolt 7. The cap 8 is movably embedded in the top of the bolt 7 to cover the bolt 7. The gear knob 9 can be detachably fixed to the top of the regulating valve core 2 through the provided bolt 7, so that the regulating valve core 2 can be adjusted by turning the gear knob 9, thereby improving work efficiency.

[0029] Furthermore, a mounting cover 3 is rotatably installed on the outer periphery of the regulating valve core 2, and the mounting cover 3 is fixedly connected to the regulating valve seat 1 through a fixing component. Through the provision of the mounting cover 3, after the regulating valve core 2 is installed in the regulating valve seat 1, it can be fixed to the regulating valve seat 1 through a fixing component (the fixing component can be a screw), thereby increasing the stability of the regulating valve core 2 in the regulating valve seat 1.

[0030] Furthermore, there is a gap between the mounting cover 3 and the regulating valve seat 1, and an elastic component is provided in the gap, wherein the elastic component includes an elastic paddle 10 and a gasket 11, one end of the elastic paddle 10 is fixedly provided at the lower end of the mounting cover 3, and the regulating valve seat 1 is further provided with a ball groove 19, and the ball groove 19 is located below the gap, and a plurality of balls 4 are provided in the ball groove 19, and the gasket 11 is provided between the elastic paddle 10 and the plurality of balls 4.

When the bolt 7 or nut is loosened due to vibration, the elastic paddle 10 can automatically compensate for such loosening and keep the connection tight. When the regulating valve core 2 is rotated, the plurality of balls 4 are moved in the ball groove 19, thereby increasing the controllability of the regulating valve seat 1 when adjusting the damping force value. The gasket 11 can reduce the direct contact between the elastic paddle 10 and the plurality of balls 4 and reduce friction.

[0031] Furthermore, a sealing component 12 is installed between the regulating valve core 2, the mounting cover 3 and the regulating valve seat 1, and the sealing component 12 is an O-ring, which can seal the connection between the regulating valve core 2 and the regulating valve seat 1 to prevent oil leakage and increase the sealing performance when the regulating valve core 2 and the regulating valve seat 1 are connected.

The guide 15 has a hole connecting the oil guide pipe and the inner cavity of the working cylinder 17. The piston rod 18 is provided to drive the piston 14 to move in the working cylinder 17, driving the oil in the working cylinder 17 to enter the oil guide pipe 16 through the guide 15, and then enter the oil drain tank 5 through the oil guide pipe 16, and then enter the oil storage cylinder 13 through the oil drain tank 5. In this way, a damping force value can be generated to achieve a shock absorption effect during the driving of the car. When the piston 14 is reset, the oil in the oil storage cylinder 13 can be driven back to the working cylinder 17.

[0033] Furthermore, a branch oil pipe 20 is provided between the oil guide pipe 16 and the oil drain tank 5. One end of the branch oil pipe 20 passes through the regulating valve seat 1 and is connected with the oil drain tank 5, and the other end of the branch oil pipe 20 is connected with the oil guide pipe 16. Through the provided oil guide pipe 16, when in use, a part of the oil in the working cylinder 17 can enter the oil guide pipe 16 through the guide 15, and then enter the oil drain tank 5 through the branch oil pipe 20 on the oil guide pipe 16, thereby generating a damping force value to achieve a shock absorption effect.
