Embodiment

[0023] Such as figure 1 As shown, the automotive shock absorber with capillary variable damping in series in 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 lower oil tank 2-2, also comprises the capillary tube group that is formed by many capillary tubes 5,7,9,11 connected in series, is all connected in parallel with the electromagnetic valve 6,8,10 that plays by-pass effect at the both ends of every capillary tube 12. The capillary tubes connected in series form two general ports, one of which communicates with the upper oil chamber of the cylinder body, and the other general port communicates with the lower oil chamber of the cylinder body.

[0024] The capillary includes a No. 1 capillary 5, a No. 2 capillary 7, a No. 3 capillary 9 and a No. 4 capillary 11; the solenoid valve includes a No. 1 solenoid valve 6 connected in...

Abstract

The invention discloses an automobile damper with a variable damp of capillary tubes in serial connection. The automobile damper 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 serial connection; solenoid valves with a bypass function are in parallel connection with two ends of each of the capillary tubes; two head ports are formed by the capillary tubes in serial connection; one of the head ports is communicated with the upper oil cabin of the cylinder body; the other head port is communicated with the lower oil cabin of the cylinder body; the diameters of the capillary tubes are the same and the capillary tubes are arranged in a proportional sequence of length from short to long; and different throttling lengths are obtained by controlling different switch-on / off states of the solenoid valves, so as to obtain different damping characteristics of the damper. The automobile damper provided by the invention is smart in conception; the technical means is simple and is easily performed; and the traditional hydraulic damper structure is only slightly changed, but the damping quality of the damper is greatly promoted.

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 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. 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 capillary tubes in series, and solve the problem that the dam...
