Wheel radial load fatigue testing machine is used for durability test of wheels. . The testing machine simulates the road surface with the surface of the drum, and the motor drives the drum to rotate. Each test station has a set of hydraulic servo loading system, which presses the test rim and tire assembly fixed on the station shaft on the surface of the drum, and carries out the test at a preset test speed and test load, and the loading force value of each station can be set independently.

The drum of the main machine of the testing machine has a smooth surface and no obstacles. The drum of the testing machine is driven to rotate by motor and belt drive. The test load is controlled by hydraulic servo closed loop, and the control system controls the high-precision servo control loading electric cylinder to realize closed loop servo loading.
Equipped with a high-voltage control box to complete the drive control of the motor. The microcomputer control unit is equipped with a commercial control computer. The computer has a built-in signal amplification A/D conversion card to complete the signal amplification and analog-to-digital conversion of the sensor. The computer software is WINDOWS platform software, which has the functions of dynamic display, storage and output of test reports. Through the man-machine interface, it includes the running program management, parameter setting, data acquisition-display-recording, data calibration and equipment fault diagnosis. The control system automatically controls the tire test speed and load, automatically records relevant test data, and generates test reports in Excel format.
