Thereby adjusting the pre-pressure exerted by the adjustment cylinder C630 on the overload spring C530. Thereby adjusting the torque required to rotate side end gear C475 relative to side end power shaft C250.

Since the overload spring C530 applies an axial thrust to the first thrust bearing C481, a certain torque is required for the relative rotation between the side-end gear C475 and the side-end power shaft C250. Side end gear C475 and side end power shaft C250 rotate in unison before this torque is reached, while side end gear C475 and side end power shaft C250 are in a relatively stationary condition. Once the side end gear C475 cannot rotate, the side end power shaft C250 and the side end gear C475 rotate relatively, so that the side end gear C475 is driven by the screw to move down along the side end power shaft C250, and finally the side end gear C475 is separated from the side end rack C610 engaged with the side end gear C475, and the screw thread of the side end gear C475 which is screwed with the side end power shaft C250 reaches the end, so that the side end gear C475 moves down to the maximum displacement point and presses the overload spring C530, and the overload spring C530 stores the elastic force. Once the lateral-end power shaft C250 rotates reversely, the lateral-end gear C475 moves upward and returns to the state of meshing with the lateral-end rack C610, and after returning to the initial state, the screw thread of the lateral-end power shaft C250 and the lateral-end gear C475 is threaded to the end, so that the lateral-end gear C475 moves upward to the maximum displacement point.

The two side end racks C610 of the two side end positioning assemblies are respectively in meshing transmission with different side end gears C475, that is, two side end power shafts C250 are provided. With the design, when one of the side end racks C610 moves to the right position and the other side end rack does not move to the right position, the side end gear engaged with the side end rack C610 which moves to the right position moves axially downwards until the side end gear is separated from the side end rack C610, and the other side end gear continues to drive the other side end rack to move until the other side end rack moves to the right position (the side end travel switch corresponding to the side end rack is triggered), so that the positioning and the pressing of the two ends of the bogie 100 can be completed. The positions of the two ends of the steering frame relative to the second positioning frame plate B170 can be calculated through the rotating speed of the side end motor, the parameters of each gear rack and the triggering time of the two side end travel switches, so that error compensation is realized to improve the positioning accuracy.

Preferably, in order to prevent the side end gear C610 from moving after the side end gear C475 is separated from the side end rack C610, the side end gear C610 is not allowed to move upwards due to the fact that the side end gear C610 moves upwards and returns to move upwards. And because the lateral end positioning assembly is required to press the lateral sides of the two ends of the bogie, if the lateral end rack C610 is not fixed, the lateral end rack is likely to move, so that a large positioning error is caused. The rack brake frame C710 is designed by the applicant, the rack brake frame C710 comprises a brake bottom plate C711 and a brake plate C712, a brake sliding shaft C650 is installed at the bottom of the brake bottom plate C711, a brake spring C640 is sleeved at the bottom of the brake sliding shaft C650, penetrates through the brake shaft plate C661 and can be axially assembled with the brake shaft plate C661 in a sliding mode, the brake shaft plate C661 is installed on a brake vertical plate C660, and the brake vertical plate C660 is installed on an overload bottom plate C170.

After the side-end rack C610 moves to the right position (the corresponding side-end positioning component positions and presses the bogie), the side-end power shaft C250 continues to rotate, so as to drive the side-end gear C475 to move downwards, and the first thrust bearing C481 and the second thrust bearing C482 are pressed in the process of moving downwards of the side-end gear C475, so as to drive the rack brake frame C710 to move downwards until the brake plate C712 is pressed against the top of the side-end rack C610, at this time, the side-end gear C475 is separated from the side-end rack C610, and the side-end gear C475 moves downwards to the maximum displacement point. And the brake plate C712 can prevent the side-end rack C610 from sliding after being pressed against the side-end rack C610.
