Abstract

The invention provides a multi-pipe connected inerter device. The multi-pipe connected inerter device includes a hydraulic cylinder tube, the interior of the hydraulic cylinder tube is provided with apiston rod which is fixedly connected with a piston, the piston divides the hydraulic cylinder tube into an upper cavity and a lower cavity, through holes which are symmetrical relative to the central axis of the piston rod are formed in the cylinder wall of the upper cavity and the cylinder wall of the lower cavity, and the through holes of the upper cavity and the lower cavity separately communicate with the two ends of an internal cavity of a communicating pipe. An anti-collision device is arranged below the hydraulic cylinder tube, a magnetic valve is installed at the positions of the through holes of the tube walls of the upper cavity, the radius r1 of the hydraulic cylinder tube is larger than the internal radius r2 of an internal cavity, and r1=(10-15)r2. According to the device, the communicating pipe and the hydraulic cylinder tube are integrated, the vibration can be absorbed more quickly, the response is quicker, and the purposes of compact structure, reducing of the spacedistribution and convenient installation and configuration are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle shock absorbers, in particular to a multi-pipe connection container device. Background technique [0002] With the continuous development and improvement of automobile manufacturing technology, people have higher and higher requirements for the ride comfort of automobiles, and more and more people pay attention to the problem of automobile vibration. At this stage, automobiles mainly use shock absorbers to alleviate the impact of automobile vibration on ride comfort. The use of shock absorbers can not only improve ride comfort, but also reduce the loss of other auto parts and prolong the service life of spare parts. Therefore, the study of shock absorbers has also become a hot research in the field of automobiles. [0003] So far, there have been many studies on shock absorbers at home and abroad. Most of the shock absorbers used in the market are spring shock absorbers, hydraulic shock absorber...
