48-inch car chassis dynamometer--two-wheel drive/four-wheel drive (1*2/2*2/2*4/4*4)

The 48-inch chassis dynamometer is a chassis dynamometer suitable for performance testing of passenger cars and light vehicles. It has high accuracy and repeatable quality simulation. The use of a three-phase asynchronous motor positioned between the rotating hubs ensures space saving, low performance loss and high torsional rigidity. It is used in front-wheel, rear-wheel and all-wheel-drive vehicles in single-axle and dual-axle configurations to ensure high dynamic stability of the front and rear axles. The system can simulate the road resistance with full electric inertia, reproduce the road resistance of the vehicle under test or customize the road resistance, and meet the dynamic, economic, regulatory and durability tests of the whole vehicle. ● 48-inch (1219.2mm) rotating hub, AC motor, suitable for light vehicles ●The principle of central motor, side motor or multiple motors ●High precision and high repeatability for quality simulation ●The accuracy is higher than EPA requirements ●Extremely compact design ●High dynamic stability ●Intelligent bearing design ●Configure common emission test system interface ●Automation software module ●Convenient system upgrade
