The invention discloses a piston and a composite electromagnetic suspension actuator, belongs to the field of electromagnetic suspensions, and aims to provide better damping force while realizing rapid stretching. The piston head is fixed to the bottom of the piston rod, an elastic shifting piece is arranged in the piston head, and a small hole is formed in the elastic shifting piece. The piston rod is sleeved with the elastic poking piece, the outer side wall is fixed to the inner wall of the piston head, the inner side wall is free, and a check ring is pressed on the piston rod and located above the elastic poking piece to limit the elastic poking piece. Vibration reduction oil is injected into a vibration reduction oil cavity defined by the sealing device, the inner side wall of the oil storage cylinder and the floating piston. When the piston head moves downwards, the inner side of the elastic shifting piece cannot be bent upwards to be opened, and damping oil can only pass through the small hole in the elastic shifting piece. The piston head moves upwards, the inner side of the elastic shifting piece is completely jacked open, damping oil can pass through the small hole and an opening between the elastic shifting piece and the piston rod, the liquid flow area is increased, the drainage speed is increased, and the actuator can be rapidly stretched.
本发明活塞及复合式电磁悬架作动器,属于电磁悬架领域,目的是实现快速拉伸同时提供较好阻尼力。活塞头固定于活塞杆底部,活塞头内设置有弹性拨片,弹性拨片上设置有小孔;弹性拨片套在活塞杆上,外侧壁固定于活塞头的内壁,内侧壁自由,活塞杆上压装有挡圈,挡圈位于弹性拨片上方对弹性拨片构成限位。减振油注入密封装置、贮油筒内侧壁和浮动活塞围成的减振油腔内。活塞头往下运动,弹性拨片内侧不能向上弯曲打开,减振油只能通过弹性拨片上的小孔。活塞头往上运动,弹性拨片内侧被完全顶开,减振油可从小孔和弹性拨片与活塞杆之间的开口通过,液流面积增大,泄流速度加快,使作动器可以快速拉伸。
