Abstract: The invention provides a four-station road vehicle wheel radial fatigue test device and method. The device includes wheel and tire assemblies, wheel and tire assembly supporting and loading devices, a drum and a bracket. The device can realize simultaneous test on four test stations, thereby improving the utilization rate of equipment, and increasing the test efficiency. By adopting the vertical drum, the size and occupation area of the test device are reduced, and the wheel and tire assemblies are more convenient to install and remove. By adopting the servo motor as a power source for the drum and the wheel and tire assembly supporting and loading devices, the rotating speed and the load are easier to control, and the accuracy is higher.
