Working Principle of Car Brake Tester

Brake tester is used to test the braking performance of motor vehicles, which is mainly used in the field of car making and maintenance. It can test whether the braking performance of the vehicle meets the standard or not by measuring the rotation speed and braking force of the wheel, the braking distance and other parameters.

The working principle of the brake tester mainly includes the following aspects:

I. Calculation of braking force equivalent coefficient

Braking force equivalent coefficient refers to the equivalent value of wheel braking force on the platform after calculation. In the brake test, the braking force applied to the wheel by the control brake will not always be the same, but it will be in an upward trend. In this process, the calculation of braking force equivalent coefficient is very important, and a more accurate braking force equivalent coefficient can be obtained by a certain calculation method.

2. Hub speed and test data collection

Brake tester tests the rotation speed of the wheel through the sensor installed on the hub of the vehicle, calculates the acceleration of the wheel according to the measured data, and then calculates the braking force and braking distance of the vehicle. At the same time, the brake tester will collect and store data in real time, such as braking force equivalent coefficient, braking time, braking distance and other parameters, and output the data to the computer system for processing and analysis.

3. Data processing and analysis

The data collected by the brake tester needs to be processed and analyzed by computer. The computer can analyze the collected data and calculate the braking performance of the vehicle under different road conditions and environmental conditions, such as braking distance, braking time, braking force equivalent coefficient and so on. In parallel, the computer can also display the data and generate reports, providing a more accurate reference for maintenance and inspection.

To sum up, the working principle of the brake tester mainly includes the calculation of braking force equivalent coefficient, the collection of wheel hub speed and test data, and the processing and analysis of data. These processes are in cooperation with each other and can provide users with more accurate results for vehicle braking performance.
