The clamping forces of the right front stabilizing wheel 91, the right rear stabilizing wheel 91, the left front stabilizing wheel 91 and the left rear stabilizing wheel 91 can cause the bearing force of the left running wheel 90 and the right running wheel 90 and the change of the horizontal angle of the bogie assembly 200, and the bearing force of the left running wheel 90 and the right running wheel 90 and the real-time value of the horizontal angle of the bogie assembly 200 are required to be ensured to be within the required range;

step S08, adjusting the clamping force of the guide wheel 92: the clamping force of the left guide wheel 92 and the right guide wheel 92 is adjusted by increasing or reducing the special gasket between the support of the guide wheel 92 and the bogie assembly 200, so that the stress of the stabilizing wheel 91 is between 700 and 900N, and the clamping force of the left guide wheel 92 and the right guide wheel 92 can be displayed in real time through upper computer software;

step S09, adjusting the contact force of the collector: the contact force between the positive electrode collector shoe and the left conductive rail 50 and the contact force between the negative electrode collector shoe and the right conductive rail 50 are regulated by a contact force regulating mechanism carried by the collector shoe, and are manually regulated to be between 30N and 50N;

step S10, releasing the load pressure: and an instruction is sent to the CompactRIO controller through upper computer software to sequentially control the left servo hydraulic valve and the right servo hydraulic valve to output and control the actuator 82 and the actuator 82 to release the load pressure, and the hydraulic pressure plates 84 of the left loading hydraulic cylinder and the right loading hydraulic cylinder are removed to be connected with the two support seats of the bogie assembly 200.

And step S10, the upper computer software automatically records and stores the measurement data in the adjustment process, and the adjustment of the bogie assembly 200 is completed.
