Shock absorber, shock absorption system and excavator
The invention provides a shock absorber, a shock absorption system and an excavator, the shock absorber comprises a cup-shaped shell, a rubber body fixed in the shell in a sealed mode, a bearing connecting column axially arranged in the center of the rubber body and an electromagnetic device, and the rubber body and the shell form a sealed space in the shell; a damping plate fixedly connected with the end of the bearing connecting column is arranged in the sealed space, the peripheral edge of the damping plate is in clearance fit with the inner wall face of the shell, the sealed space is filled with magnetorheological fluid, and the electromagnetic device is configured to be capable of generating a magnetic field in a cavity between the damping plate and the rubber body. According to the magneto-rheological damper, the electromagnetic device is powered on at a proper time to generate a magnetic field, and tiny magnetic particles in the magneto-rheological fluid are regularly arranged under the action of the magnetic field, so that the damping of the magneto-rheological fluid is changed, the damper adapts to the current working condition, and impact is reduced.
本发明构造一种减震器、减震系统和挖掘机，其中减震器包括杯状壳体、密封固定于壳体内的橡胶体、轴向布置于橡胶体中心位置的承载连接柱、电磁装置，所述橡胶体与所述壳体在壳体内形成密封空间，在密封空间内布置有与所述承载连接柱端部固定连接的阻尼板，所述阻尼板四周边缘与所述壳体内壁面间隙配合，所述密封空间内填充磁流变液，所述电磁装置配置为能够在所述阻尼板与橡胶体之间的腔室内产生磁场。在本发明中，在适当的时机向电磁装置通电产生磁场，磁流变液中的微小磁性颗粒在磁场作用下规则排列，从而改变磁流变液阻尼，使减震器适应当前工况，减小冲击。
