Embodiment

[0025] Such as figure 1 As shown, the automobile shock absorber with parallel capillary variable damping of the present invention includes a cylinder body 2 and a piston 3 placed in the cylinder body 2. The inside of the cylinder body 2 is bounded by the piston 3 and is divided into an upper oil tank 2-1 And the lower oil tank 2-2 is characterized in that it also includes a capillary group composed of four capillary tubes 5, 7, 9, 11 connected in parallel, a general port of the capillary group communicates with the upper oil tank 2-1 of the cylinder body, and the capillary tube Another total port of the group communicates with the lower oil tank 2-2 of the cylinder body.

[0026] The capillary group includes No. 1 capillary 5 , No. 2 capillary 7 , No. 3 capillary 9 and No. 4 capillary 11 . Except for No. 1 capillary 5, the remaining three capillaries 7, 9, 11 are all connected in series with a solenoid valve 6, 8, 10; wherein, No. 2 solenoid valve 6 is connected in series wit...

Abstract

The invention discloses a damp-variable automobile damper with capillary tubes in parallel connection, which comprises a cylinder body, a piston in the cylinder body and a capillary tube set, wherein the interior of the cylinder body is divided into an upper oil cabin and a lower oil cabin by the piston; the capillary tube set is composed of a plurality of capillary tubes in parallel connection; one head port of the capillary tube set (N is more than or equal to 2) is communicated with the upper oil cabin of the cylinder body; the other head port of the capillary tube set is communicated with the lower oil cabin of the cylinder body; the N capillary tubes are arranged in a proportional sequence of area from small to big; except for the first capillary tube, other capillary tubes are all provided with solenoid valves; the switch-on / off of the solenoid valves is controlled according to the damping characteristic configuration of the damper; and different throttling areas can be obtained by selecting different configurations, so as to obtain different damping characteristics of the damper. The purpose of changing the damping characteristics of the damper in a wide range is achieved. The damp-variable automobile damper provided by the invention is smart in conception; the technical means is simple and is easily performed; and the damping quality of the damper can be greatly promoted by only slightly changing the traditional hydraulic damper structure.

Description

technical field [0001] The invention relates to the field of hydraulic automobile shock absorbers, in particular to an automobile shock absorber with variable damping of parallel 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. Damping characteristics are the most important performance indicators of automobile shock absorbers. The biggest disadvantage of hydraulic shock absorbers at present is that the damping characteristics of shock absorbers are fixed and cannot be adjusted or the adjustable range is very small. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, provide an automobile shock absorber with variable damping of parallel capillary tubes, and solve the problem that the da...
