Embodiment 1
[0046] Please also refer to Figure 1 to Figure 7 , a specific implementation manner of a steering system testing device provided by the present invention will now be described. The steering system testing device includes a power system 1 , a data acquisition system 2 and a support assembly 3 , wherein the power system 1 is connected to the system to be tested 4 for driving the motion of the system to be tested 4 ; the data acquisition system 2 includes a connection to the power system 1 The angle obtaining member 21 is used to obtain the rotation angle of the power system 1; the support assembly 3 is respectively connected with the power system 1 and the data acquisition system 2, and the support assembly 3 includes a hydraulic support 31 connected with the system to be measured 4, Several hydraulic supports 31 are provided, and the spacing between the plurality of hydraulic supports 31 is adjustable.
[0047]Exemplarily, there are eight hydraulic supports 31, two of which a...
Embodiment 2
[0050] As a specific implementation of the embodiment of the present invention, please refer to Figure 1 to Figure 7 , the structure of a steering system testing device provided in this embodiment is basically the same as that in Embodiment 1, the difference is that the power system 1 includes a driver 11 and a universal shaft 12, wherein the driver 11 is connected with the support assembly 3, and with the data The acquisition system 2 is electrically connected, and the driver 11 can be a combination of the servo motor 111 and the reducer 112; The joint 41 is connected to the support assembly 3, and the universal shaft 12 can be a universal joint. The data acquisition system 2 outputs a control signal to the driver 11 to control the driver 11 to work as required. The driver 11 transmits the torque to the universal joint shaft 12 through the coupling 13 , and the universal joint shaft 12 outputs the torque to provide the driving force for the system to be measured 4 .
