Wherein, the one end fixed connection first slide 16 of turning to ball 4 is kept away from to second connecting rod 3, first slide 16 is circular, first slide 16 and 2 clearance fit in buffering hydraulic pressure chamber, when the train right driving braking, the first slide 16 in left side has the trend of continuing to move right and extrudees the hydraulic oil of back chamber 18 in the left buffering hydraulic pressure chamber 2 of first connecting rod 1, because first slide 16 and 2 clearance fit in buffering hydraulic pressure chamber, so the hydraulic oil in back chamber 18 can slowly shift to preceding chamber 17 through the gap, the hydraulic oil in the back chamber 18 in the first connecting rod 1 right side can slowly shift to preceding chamber 17 through the gap, reach the effect of buffering. The first slide plate 16 divides the cushion hydraulic chamber 2 into a front chamber 17 and a rear chamber 18, the front chamber 17 being located outside the first slide plate 16, and the rear chamber 18 being located inside the first slide plate 16. The diameter of the first sliding plate 16 is larger than that of the second connecting rod 3, so that the first sliding plate 16 is prevented from being separated from the buffer hydraulic cavity 2, and the connecting part of the second connecting rod 3 and the first connecting rod 1 is sealed, so that hydraulic oil is prevented from leaking. The inner side of the steering limiting block 5 is in clearance fit with the steering ball 4, so that the steering ball 4 can relatively rotate towards the limiting block 5. Two sides of the steering connecting plate 12 are parallel, so that the steering connecting plate 12 can slide in the independent cavity 10, and the steering limiting block 5 is fan-shaped. One end of the steering connecting plate 12, which is far away from the second connecting rod 3, is fixedly connected with a second sliding plate 19, and the thickness of the second sliding plate 19 is larger than that of the steering connecting plate 12, so that the second sliding plate 19 is prevented from being separated from the independent cavity 10.

One specific application of this embodiment is:

when the invention is used, when a train runs to the right and brakes, the left carriage plate 13 has a tendency of moving to the right relative to the right carriage plate 13, because the connecting seat 6 is fixedly connected with the carriage, the steering limiting block 5 is fixedly connected with the connecting seat 6, the steering ball 4 is in clearance fit with the steering limiting block 5, the steering ball 4 is fixedly connected with the second connecting rod 3, the second connecting rod 3 is fixedly connected with the first sliding plate 16, and the first sliding plate 16 is in sliding connection with the buffer hydraulic chamber 2, when the train runs to the right and brakes, the tendency of the left first sliding plate 16 moving to the right again extrudes the hydraulic oil in the rear chamber 18 in the buffer hydraulic chamber 2 on the left of the first connecting rod 1, because the first sliding plate 16 is in clearance fit with the buffer hydraulic chamber 2, the hydraulic oil in the rear chamber 18 can be slowly transferred to the front chamber 17 through a gap, and similarly the hydraulic oil in the right rear chamber 18 of the first connecting rod 1 can be slowly, rigid force generated when the train is braked is converted into flexible force to achieve the effect of buffering. When the train turns to, goes up a slope or goes down a slope, the second connecting rod 3 is fixedly connected with the steering ball 4, and the steering ball 4 is in clearance fit with the steering limiting block 5, so that the steering ball 4 can rotate relative to the steering limiting block 5, and the train is convenient to turn. Because the turning ball 4 and the turning limiting block 5 have the turning property, when the train brakes on a curved track, the first connecting rod 1 and the second connecting rod 3 can be caused to rotate, and the distance between the carriage and the carriage is very short, which can cause the second connecting rod 3 to collide with the connecting seat 6, so a corresponding structure is designed to avoid that, when the second connecting rod 3 rotates, the wall of the second connecting rod 3 can extrude the turning connecting plate 12, because the second sliding plate 19 fixedly connected with the turning connecting plate 12 is in sliding connection with the independent cavity 10, the pressed turning connecting plate 12 can slide towards the inside of the independent cavity 10, and further the hydraulic oil in the independent cavity 10 and the common cavity 9 is compressed, the hydraulic oil in the independent cavity 10 and the common cavity 9 is in an insufficient state, when the second connecting rod 3 touches the connecting seat 6, the common cavity 9 and the independent cavity 10 are filled with the hydraulic oil, and the turning connecting plate 12 prevents the second connecting rod 3 from continuing to rotate, the anti-collision effect is achieved. When the connecting assembly is maintained, the fastening bolt 21 can be rotatably removed, and hydraulic oil is injected into the hydraulic chamber through the oil injection hole 14. The invention converts rigid force into flexible force when the train brakes, achieves the buffer effect, avoids the excessive abrasion of the carriage connecting assembly, prolongs the service life of the carriage connecting assembly, and weakens the abrasion of the carriage connecting assembly when the train turns, goes up a slope and goes down a slope.
