[0022] See also Figure 1The present embodiment discloses an oil compensation structure for a shock absorber, comprising an upper connecting ring 1, a lower connecting ring 2 and a compensation mechanism 3. The upper connecting ring 1 is provided with a step opening 11 on the outer side of the bottom, and the step opening 11 is press-fitted on the inner side of the top of the lower connecting ring 2 to form a connecting ring mechanism. The upper connecting ring 1 and the lower connecting ring 2 are provided with oil through holes 4, and a cavity 5 that can be connected to the oil through holes 4 is formed between the upper connecting ring 1 and the lower connecting ring 2. The lower connecting ring 2 is provided with a plurality of compensation oil holes 21 that can be connected to the cavity 5. Specifically, the compensation oil holes 21 are distributed in a ring shape with the center of the lower connecting ring 2 as the midpoint.

[0023] The compensation mechanism 3 is arranged on the lower connecting ring 2 in the cavity 5 .

[0024] The outer side of the lower connecting ring 2 is inclined from top to bottom, which increases the flow area of ​​the oil, reduces the negative impact of the oil flow process, saves 15%-20% of materials, and ensures the mechanical properties of the connecting ring mechanism.

[0025] Furthermore, a plurality of grooves are provided on the edge of the lower connecting ring 2 .

[0026] The compensation mechanism 3 includes a compensation valve plate 31, an elastic baffle plate 32, and an elastic member 33.

The elastic member 33 is arranged between the compensation valve plate 31 and the elastic baffle plate 32, and the elastic member 33 is always in a compressed state. In this embodiment, the elastic member 33 is a compensation spring.

[0027] Furthermore, a riveted portion 22 is provided at the top of the oil hole 4 on the lower connecting ring 2, and the riveted portion 22 is provided with an annular step. However, after the elastic baffle 32 is sleeved on the annular step, the riveted portion 22 is pressed downward and deformed by riveting, so that the elastic baffle 32 is clamped on the annular step for fixation.

[0028] The working principle of this embodiment is: during the compression stroke, when the oil pressure in the compensation oil hole 21 exceeds the compression force of the elastic member 33, the compensation valve plate 31 moves away from the compensation oil hole 21, so that the compensation oil hole 21 is connected to the cavity 5, and the oil is adjusted according to the pressure of the elastic member 33. Figure 1 The oil in the direction of the middle arrow enters the cavity 5 from the compensation oil hole 21 and then enters the oil through hole 4, and finally compensates to the middle cylinder and finally compensates to the upper cavity of the working cylinder.
