[0045] figure 1 , figure 2 See the background technology section for related content.

[0046] Such as image 3 shown. The resistance adjustment section includes four capillaries, which are R8, R4, R2, and R1; they have the same cross-sectional area and are connected in parallel with the solenoid valve V R8 , V R4 , V R2 , V R1 control its work. The ratio of the lengths of these four capillaries is 8:4:2:1; their diameters are all d R .

[0047] The frequency modulation section includes four capillaries, which are m8, m4, m2, and m1; they have the same cross-sectional area and are connected in parallel with the solenoid valve V m8 , V m4 , V m2 , V m1 Control its work; the ratio of the lengths of these four capillaries is 8:4:2:1. In the present embodiment, the length L of the shortest capillary m1 among the four capillaries m1 Equal to the length L of the longest capillary R8 in the resistance adjustment section R8 half of. The diameter d of these four capill...

Abstract

The invention discloses a damper provided with matrix series capillary tubes and the variable system natural frequency. A capillary tube series damping associated segment and a capillary tube series system natural frequency associated segment are connected in sequence from top to bottom on a pipeline between an oil conveying port of an upper oil bin and an oil conveying port of a lower oil bin. The capillary tube series damping associated segment comprises four capillary tubes which are in series connection sequentially, and the two ends of each capillary tube are both in parallel connection with a solenoid valve used for controlling the capillary tube to work. The capillary tube series system natural frequency associated segment comprises four capillary tubes in series connection, and each capillary tube is in parallel connection with a solenoid valve used for controlling the capillary tube to work. The diameter of the smallest capillary tube in the frequency modulation segment is far greater than that of the capillary tubes in the damping modulation segment. In a matrix working state table, the configuration value Smn of the solenoid values in the frequency modulation segment is selected according to circumstances, and by changing the mass, the problem that the system natural frequency of a hydraulic damping system of an automobile is nonadjustable or is small in adjustable range can be solved.

Description

technical field [0001] The invention relates to the field of hydraulic automobile shock absorbers, in particular to a shock absorber with a variable system natural frequency of matrix (type) series capillary tubes. Background technique [0002] The vibration reduction methods of automobiles mainly include hydraulic type, pneumatic type and electromagnetic type. The hydraulic type is currently the most widely used vehicle vibration reduction method. The system natural frequency of the hydraulic shock absorber is an important performance index of the automobile shock absorber. A disadvantage of the current hydraulic shock absorber performance is that the system natural frequency of the shock absorber cannot be adjusted or the adjustable range is very small. [0003] The quality of the natural frequency of the hydraulic vehicle shock absorber system will directly affect the vibration amplitude, comfort and ride comfort of the vehicle. [0004] It is well known that for an ide...
