What Is The Car Test Line

Car is an indispensable part of people's work and life in modern society. With the people driving safety and comfort requirements continue to improve, automotive testing technology more and more attention, car testing and maintenance show a huge market prospects. As an important part of the car diagnostic equipment, automotive testing line for automotive manufacturers quality inspection departments, the government departments of the test station, 4S shop, auto repair shop, automotive technology training schools and many other places.

The car detection line is a kind of detection system with high detection quality, reliable data and complete detection system, which can combine the individual testing equipment, which can quickly and accurately reflect the various mechanisms of the automobile and System components of the technical situation, and pointed out that the fault lies.

What is the car test line

      The car detection line is mainly composed of three parts: brake test stand, suspension test stand and side slip test station.

        The brake detection station is a device that detects the braking performance of the vehicle, which directly affects the safety of the vehicle. The more common brake detection platform on the market for the drum brake detection platform, in addition to flat brake detection station. This equipment mainly detects the wheel braking force, braking force balance, ellipticity, blocking force 4 parameters.

       Suspension test stand is used to detect vehicle vibration performance equipment, but also can measure axle weight. Suspension test station mainly measure two parameters, namely, resonant frequency and grip. Usually hanging in the frequency range is 13 ~ 18Hz, in this range the driver will feel more comfortable.

       In addition, the difference between the relative values of the left and right sides of the suspension should not exceed 15%; the difference between the resonant frequencies on the left and right sides should not exceed 3Hz.

The sliding test bench is a device used to quantitatively detect the amount of vehicle side slip. As the car front wheel positioning does not necessarily match, so need to measure the left and right direction of the wheel offset. The sliding value is the dynamic comprehensive parameter of the four-wheel positioning system of the automobile, which directly affects the handling stability and safety of the automobile, and affects the ability of the automobile steering mechanism and the tire's wear resistance. The current national standard is a slope of not more than 5m / km.

       The entire detection line equipment by the computer control, measurement results to digital, graphics and other display, and can be printed by the printer output.

        Some advanced detection lines, you can also connect all the computers, the test results will be transmitted to the terminal computer for analysis.

Development and Future Trend of Automobile Test Line

Automatic automotive test line will be in the field of future detection of absolute status. Distributed measurement and control system because of its outstanding advantages will replace the centralized measurement and control system. Functional, easy networking, high precision testing equipment will be more and more popular. Detection system hardware toward the modular, standardized, serialized direction of development, reliability, real-time response, scalability more attention. Through the Internet for remote diagnosis and maintenance has been exposed.
