Problems solved by technology

Not only the structural parameters (such as wheelbase, wheelbase, floor height) of traditional trolleys are very different from those of real cars, but once the trolleys are designed and manufactured, their structures often cannot be changed, which makes traditional trolleys Cannot adapt to different size body
In order to develop other models (such as the design matching of the occupant restraint system), it is necessary to redesign the trolley, but this is often extremely uneconomical in terms of time cost and money cost

Abstract

An adjustable-type trolley for an impact test comprises a trolley frame (1) and wheels (3), and further comprises a front wheel track adjusting mechanism (8), a rear wheel track adjusting mechanism, a trolley axle track adjusting mechanism (12) and a bottom plate height adjusting mechanism (10), wherein the rear wheel track adjusting mechanism is integrated with the trolley axle track adjusting mechanism (12). The adjustable-type trolley for the impact test disclosed by the invention can adjust the wheel track of the wheels and an axle track, and correspondingly adjust the height of a trolley bottom plate, so as to realize good combination with varisized trolley bodies. Moreover, the adjustable-type trolley for the impact test is simple in structure, convenient in adjustment, and low in cost.

Description

technical field [0001] The invention relates to an automobile safety testing device, in particular to an automobile collision test bench used for safety research, test and inspection of vehicles. Background technique [0002] In order to increase the safety performance of the vehicle, as well as the most reliable design of the strength and stability of various facilities in the vehicle, before putting into production, the performance of the prototype vehicle should be dynamically tested to evaluate the comprehensive strength and comprehensive strength of each test component when the vehicle crashes. Shock cushioning, this test is done by reproducing the deceleration waveform and the speed of the car collision simulation test. Carrying out crash tests with real vehicles can make the test results more accurate, but the test costs are quite expensive. The commonly used method is to use a simulated collision trolley, fix the vehicle body to be tested and installed with seat bel...
