Embodiment 1

[0016] Embodiment 1: refer to figure 1 and 2 , a magnetic levitation flexible shock absorber for vehicles, which has an inner cylinder 23, an upper permanent magnet 9 is installed on the upper end of the inner cylinder 23, the upper permanent magnet 9 is connected with the working rod 2 through a non-magnetic washer 8a, and the A limit spring 7 is sheathed on the working rod 2 above the non-magnetic washer 8a. The outer cylinder 18 is placed outside the inner cylinder 23 . An upper coil winding 11 and a vibration-sensitive sensor 20 are arranged between the inner and outer cylinders 23, 18 and at corresponding positions of the upper permanent magnet 9 and the lower permanent magnet 19, respectively. Upper and lower vibration-sensitive rings 12a, 12b are installed respectively on the upper and lower end faces of the upper coil winding 11, and between the lower vibration-sensitive ring 12b of the upper coil winding 11 and the vibration-sensitive sensor 20, there is a soft magn...

Embodiment 2

[0018] Embodiment 2: refer to Figure 4 , Embodiment 2 is basically the same structure as the vehicle maglev flexible shock absorber of Embodiment 1, except that in the inner cylinder 23, an intermediate permanent magnet 14 is installed between the upper and lower permanent magnets 9, 19. An intermediate coil winding 15 is provided between the outer cylinders 23, 18 and at a position corresponding to an intermediate permanent magnet 14, and upper and lower vibration-sensitive rings are respectively installed on the upper and lower ends of the upper coil winding 11 and the intermediate coil winding 15. 12a, 12b, between the lower vibration-sensitive ring 12b of the upper coil winding 11 and the upper vibration-sensitive ring 12a of the middle coil winding 15, the lower vibration-sensitive ring 12b of the middle coil winding 15 and the vibration-sensitive sensor 20, all are provided with magnetic suspension control The soft magnetic body 17 is connected with the magnetic suspens...

Abstract

The vehicular magnetically floated flexible damper includes inner barrel, upper and lower permanent magnets inside the inner barrel and connected via non-magnetic washer and work rod, outer barrel, upper winding between the inner and outer barrels in the position corresponding to the upper permanent magnet, vibration sensitive sensor between the inner and outer barrels in the position corresponding to the lower permanent magnet, magnetic float controlling pole between the upper winding and the vibration sensitive sensor, one or several middle permanent magnets between the upper permanent magnet and the lower permanent magnet, middle winding(s) and magnetic float controlling pole(s) corresponding to the middle permanent magnet(s). It has also electric energy recovering circuit to charge the accumulator. The present invention has no environmental pollution, high damping effect, full use of vibration energy and other advantages.

Description

technical field [0001] The invention relates to the field of vehicle suspension, and relates to a magnetic suspension flexible shock absorber for vehicles. Background technique [0002] The existing vehicle hydraulic shock absorber is composed of a cylinder body, a piston is built in the cylinder body, and a damping hole is arranged on the piston to make the two cavities of the cylinder body oil-liquid communicated. When the piston rod connected to the vehicle frame moves under the vibration force of the vehicle body, the damping hole on the piston can automatically adjust the pressure difference between the two chambers of the cylinder to achieve vehicle body vibration reduction. However, this kind of hydraulic shock absorber has oil leakage that pollutes the environment, reduces the vibration reduction effect, has a low service life, has noise, is greatly affected by temperature, and the vibration kinetic energy cannot be utilized. Out of control and so on. Contents of ...
