At present, relevant departments in our country need to purchase automobile chassis dynamometers, reaction brake test benches, speedometer test benches, wheel (axle) weight test benches and environmental Working ...

AI Technical Summary

Problems solved by technology

For example, in auto repair shops, related institutions of higher learning, scientific research units, and motor vehicle performance testing stations in remote areas with fewer vehicles, the above five different testing equipment must be equipped at the same time. Due to large investment, large area occupation, and low equipment utilization, The vehicles of some units and regions cannot be equipped with all the above-mentioned equipment, and all items cannot be tested
