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 ...

Abstract

The invention discloses a rear wall strength test device for driving cabs of commercial vehicles, which comprises a mounting frame assembly, a flexible driving device, a rigid loading mechanism, a displacement measuring device and a force measuring device, wherein the mounting frame assembly is provided with a pair of guide rails arranged in parallel, the pair of guide rails is arranged along the longitudinal direction of the vehicle, the rigid loading mechanism is arranged on the pair of guide rails in a sliding mode, the flexible driving device is fixed on the mounting frame assembly, an output end of the flexible driving device is connected with the rigid loading mechanism through the force measuring device, and the displacement measuring device is arranged on the guide rails. The rear wall strength test device for driving cabs of commercial vehicles has the advantages that the structure is simple, the loading direction and the loading speed are stable, the data measurement is accurate, and test results can fully reflect the real condition of the real facts of the rear wall strength of driving cabs.

Description

technical field [0001] The invention relates to a commercial vehicle strength test device, in particular to a commercial vehicle cab rear wall strength test device. Background technique [0002] With the rapid globalization of commercial vehicles, their safety issues are receiving increasing attention. The safety performance test of the commercial vehicle cab is an important way to evaluate the collision safety of commercial vehicles, and the rear wall strength test of the commercial vehicle cab is an important index to judge the safety of the commercial vehicle cab. [0003] Usually, the position directly behind the cab of a commercial vehicle is used to place cargo boxes, and its mass is relatively large. Once the fixed structure of the cargo box fails, it will collide with the rear wall of the cab, causing it to bear a large load. At the same time, the rear wall structure of the cab will be greatly deformed, thereby squeezing the living space of the occupant, and even c...
