see figures 1-2. On the basis of the second embodiment, the steering load loading system comprises a universal coupling, a loading shaft, a connecting disc 20, a loading bearing seat and a servo loading mechanism; one end of the loading shaft is connected with the synchronous steering system through a universal coupling, and the other end of the loading shaft is supported on a loading bearing seat through a bearing 22; a connecting disc 20 is fixed on the loading shaft; the servo loading mechanism is used for providing resistance for the loading shaft to drive the connecting disc 20 to rotate. According to the structure, the automobile can be subjected to steering loads of different sizes during steering due to different road conditions in the driving process, and the steering loads are truly simulated through the steering load loading system. One end of the loading shaft is connected with the synchronous steering system through a universal coupling, the loading shaft is fixedly connected with the synchronous steering system, and the universal coupling is used as a mechanical part for transmitting torque and is used for connecting the loading shaft with the synchronous steering system, so that the torque on the loading shaft can be transmitted to the synchronous steering system.

The torque of the first loading shaft 16 and the second loading shaft 24 can be measured through a torque angle sensor, and the steering angle of a synchronous steering system can also be measured. For example, the torque angle sensor can adopt an SCT-20N sensor, and can simultaneously measure the rotation angle and the torque of the steering.
