Embodiment Construction
[0027] Figure 1 to Figure 4 It shows an embodiment of a test device for the rear wall strength of a commercial vehicle cab of the present invention, the test device includes a mounting bracket assembly 1, a telescopic drive device 2, a rigid loading mechanism 3, a displacement measuring device 4 and a force measuring device 5, The mounting bracket assembly 1 is provided with a pair of guide rails 6 arranged in parallel. The pair of guide rails 6 are arranged along the longitudinal direction of the vehicle. The rigid loading mechanism 3 is slid on the pair of guide rails 6. When loading, the guide rails 6 are used to guide the loading direction to ensure the loading direction. Accurate and stable, the telescopic driving device 2 is fixed on the mounting bracket assembly 1, which can maintain a stable loading speed and create favorable conditions for improving the simulation degree of the crash test. The output end of the telescopic driving device 2 is connected with the rigid ...
