When the vehicle passes through a curve, the vehicle body and the framework generate a relative rotation angle, so that the end part L of the connecting rod is forced to generate pushing force or pulling force, the pushing force or the pulling force is directly acted on a hinge point C of the axle, and power input is provided for the push-pull mechanism 3 unit at the connection part of the axle end.

The torsion bar mechanism 1 comprises a torsion bar 12 and torsion arms 13 arranged at two ends of the torsion bar 12, and the second connecting plate 8 and the connecting rod assembly 9 are respectively hinged on the torsion arms 13 at two ends.

The D point of the axle end moves forwards to drive the HD connecting rod to move forwards, at the moment, the torque arms 13JH and KH 'rotate anticlockwise around hinge points J and K of the framework to push the GH' connecting rod to move forwards, the forward movement of the G point enables the EG connecting rod to rotate clockwise around a point F hinged on the framework, then the ED 'first connecting rod 17 moves backwards, the D' point of the axle end moves backwards to pull the A 'D' point to move backwards, subsequently, the A 'B hinge plate 16 rotates anticlockwise around a point O' hinged on the framework to force the B 'C' second push-pull connecting rod 15 to move forwards, and finally the C 'point of the axle end moves forwards, and the C' ends of the front axle and the rear axle are far away from each other. The same applies to left-hand turning. Finally, the front axle and the rear axle are in the shape of the splayed outer shape when the vehicle turns, so that the axles of the rail vehicle in the curve are always positioned at the radial position of the line curve, and the splayed outer axle has important significance for improving the curve passing capacity of the vehicle, improving the running safety of the vehicle, reducing the abrasion of wheels and reducing the noise of wheel tracks. All joints in the mechanism are connected by spherical rubber elastic nodes, so that the relative rotation between the connecting rods is flexible, and the movement performance of the mechanism is better.
