A three-degree-of-freedom swing device for a rail car

Abstract

The invention discloses a three-freedom-degree oscillating device of a rail car. The three-freedom-degree oscillating device comprises three electric cylinders and a safety arm, wherein the three electric cylinders are arranged below a car body at intervals, the electric cylinders and the safety arm are fixedly arranged on a frame. The lower end of the safety arm is movably arranged on a rack through a mobile rotating shaft, the upper end of the safety arm is connected with a spider universal joint which consists of a longitudinal axle and a horizontal axle, the longitudinal axle and the horizontal axle are respectively consistent with the length and width directions of a car body, and the longitudinal axle is movably connected with the bottom of the frame through a pin axle. On one hand, a revolving support is guaranteed to be capable of flexibly moving when the three-freedom-degree electric cylinders extend or contract, on the other hand, the motion strokes of the electric cylinders can be limited, and the revolving support and a seat thereon can be guaranteed to safely fall onto the rack to prevent the revolving support from overturning disorderly, so that the whole guide rail car is safer, and the structure is simple, stable and reliable.
