The invention relates to a rail vehicle anti-deflection energy-absorbing device, which relates to the technical field of rail vehicle passive safety. The mounting seats of the female and male anti-deflection structures are of the same structure. The rotation limiter is fixed by the rotation shaft and the lugs on both sides of the short axis direction of the rectangular frame structure. The top of the rotation limiter of the male anti-deflection structure is connected with the The outer side of the bottom is fixedly connected, and the inside of the sleeve is equipped with crushing energy-absorbing materials. The surface of the sliding circular plate is evenly distributed with four through holes that match the guide rod, and is connected to the cover plate through breaking bolts; one end of the connecting rod is connected to the sliding circular plate. fixed, and the other end is fixedly connected with the flat end of the conical connector; the trapezoidal circular table is connected with the bottom plate through the first return spring, and the end of the trapezoidal circular table with a smaller diameter is provided with a semicircular moving plate, and the four protrusions of the semicircular moving plate The output end extends into the square hole of the cylinder, and is connected with the cylinder through the second return spring; the rotating plate is connected with the inner wall of the cylinder through the rotating plate shaft, and one end is fixed in the hole of the semicircular moving plate.
Description
Technical field [0001] The invention relates to the technical field of passive safety of rail vehicles. Background technique [0002] The energy absorbing device is a safety device installed at the end of the car body. It is an important part of the passive safety technology of the train. It can absorb a certain amount of kinetic energy when the vehicle collides, which greatly improves the passive safety performance of the train. [0003] At present, the energy absorbing device is mainly combined with the anti-climbing device and applied to one end of the locomotive. When a collision occurs, on the one hand, it can absorb the collision energy, and on the other hand, it can also restrain the occurrence of climbing behavior between vehicles. When a train collides on a curved track, the vehicle does not collide with the center and is affected by centrifugal force. The train often folds laterally, which eventually causes the train to break away from the track constraints and derail, ca...
