ABS four-wheel loading performance test teaching device

Abstract

Disclosed is an ABS four-wheel loading performance test teaching device. The device comprises a power driving system and an ABS which are installed on a movable desk frame, and a control computer respectively connected with the power driving system and an information gatherer, wherein the control computer is simultaneously electrically connected with an electromagnetic loader for outputting preset currents to a brake; the power driving system is constructed in such a way that four variable frequency motors drive four transmission shafts to rotate through a driving belt so as to drive wheels to simulate operation of a real vehicle; and the ABS is electrically connected with the control computer through the information gatherer, and the information gatherer transmits collected experiment data to the control computer through a network interface and a data line in real time. The ABS four-wheel loading performance test teaching device has the following advantages: the structural composition and the work principle of the ABS can be visually known, and at the same time, the computer is used for data control and analysis so that the actual work performance of the ABS can be accurately analyzed and determined; the device is not restricted by external environment and can carry out ABS four-wheel loading test teaching or manufacturer training at any time; and the accuracy of a loading test result is high.

Description

technical field [0001] The invention relates to an automobile teaching and training equipment, in particular to an ABS four-wheel loading performance testing teaching equipment. Background technique [0002] At present, in the automobile service industry, there are relatively few technicians who fully grasp the technical characteristics and inspection and maintenance requirements of automobile ABS braking systems, and it is difficult for the labor and transportation departments to carry out technical grade assessment and assessment to involve these aspects. In terms of vocational education, limited by the external environment, operating safety, cost and price, the teaching mode of automotive ABS braking system and loading test is generally still at the stage of relying on teachers to explain theoretical knowledge, which is still very different from actual vehicle maintenance. difference. On the other hand, most of the traditional ABS and loading performance tests use the me...

Problems solved by technology

In terms of vocational education, limited by the external environment, operating safety, cost and price, the teaching mode of automotive ABS braking system and loading test is generally still at the stage of relying on teachers to explain theoretical knowledge, which is still very different from actual vehicle maintenance. difference

On the other hand, most of the traditional ABS and loading performance tests use the method of loading step by step, and the difference between two adjacent loading levels is relatively large, and the test results are often not accurate, so it is impossible to test better. ABS performance
