Abstract

The invention discloses a shock absorber which comprises a first cylinder, a first piston, a connecting pipe, a second cylinder, a second piston and an adjusting device. The first piston is movably arranged in a first inner cavity of the first cylinder, the second piston is movably arranged in a second inner cavity of the second cylinder, the connecting pipe communicates to the second inner cavityand communicates to the first inner cavity through the adjusting device, the adjusting device comprises a body, an adjusting inner gear ring and an adjusting shaft, a plurality of adjusting holes different in cross sectional area are formed in the peripheral wall of the adjusting inner gear ring, the second end of the adjusting shaft is provided with an adjusting gear engaged to the adjusting inner gear ring and penetrates a second hole to stretch into a cavity, and the adjusting shaft can rotate to drive the adjusting inner gear ring to rotate, so that a third hole communicates to the cavitythrough one of the adjusting holes. The shock absorber disclosed by the invention has the adjusting device which can adjust hardness of the shock absorber, and is wide in adjusting range and good inadjusting effect.

Description

Technical field [0001] The present invention relates to the technical field of shock absorption, and more specifically, to a shock absorber with an adjusting device. Background technique [0002] Vehicle shock absorbers are used to reduce the vibration of the frame and the body, and improve the smoothness and comfort of the vehicle. If the shock absorber is too soft, the body will easily jump up and down; if the shock absorber is too hard, it will easily bring great resistance and prevent the spring from working normally. Therefore, in order to meet the needs of different vehicles, shock absorbers with different hardnesses need to be installed. [0003] In the related art, in order to adapt to different needs, adjustment devices are provided to adjust the softness and hardness of the shock absorber. However, the adjustment range of the adjustment device in the related art is narrow, the adjustment effect is poor, and the adjustment effect of the soft and hard shock absorbers is p...
