ANTI-SIDE-ROLLING DAMPING VEHICLE-END DEVICE, AND RAIL VEHICLE AND TRAIN

The present application provides an anti-side-rolling damping vehicle-end device and a rail vehicle. The anti-side-rolling damping vehicle-end device comprises: a pair of damping mechanisms, which are adapted to respectively being installed on a pair of end walls of a pair of connected vehicle bodies that are arranged opposite each other, the pair of damping mechanisms being arranged on two sides of the axis of the vehicle bodies in a lengthwise direction, respectively; and a connecting rod, wherein two ends of the connecting rod are hinged to the pair of damping mechanisms, respectively, and the length of the connecting rod is greater than a vertical movement displacement of any vehicle body, such that side-rolling movement and vertical movement of the vehicle body is decoupled. By means of the anti-side-rolling damping vehicle-end device, it can be ensured that the length of the connecting rod connected between a pair of vehicle bodies can be far greater than a vertical movement displacement of each vehicle body, such that the movement of the damping mechanisms can be limited by means of the connecting rod in different movement processes of the vehicle body, thereby at least achieving the decoupling between side-rolling movement and vertical movement of the vehicle body. Therefore, side-rolling vibration can be suppressed more reliably while vertical stability is not affected, and the running stability and the riding comfort of a rail vehicle are greatly improved.
