The ATV vehicle chassis dynamometer is a consistency test for the production of four-wheeled all-terrain vehicles, and is an important basis for the scientific evaluation of the performance of four-wheeled all-terrain vehicles. The device performs integrated tests on the vehicle's maximum speed, acceleration, braking, and gear shifting parameters. Compared with the traditional method of using a special ground track for item-by-item test, it uses a chassis dynamometer to test the working conditions and has a small footprint. , The remarkable feature of high degree of automation can effectively improve the detection efficiency of the related performance of the four-wheel all-terrain vehicle.
