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.

The 48-inch simple chassis dynamometer is a chassis dynamometer suitable for performance testing of passenger cars and light vehicles at speeds below 100km/h. It has high-precision and repeatable quality simulations. The use of a three-phase asynchronous motor positioned between the rolls 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 modified 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.

●Strong performance and reliability
●Simple maintenance
●The rated torque of the electric dynamometer can be provided from 0 speed
●Energy feedback function
●Good economic benefits

The NVH chassis dynamometer system is an NVH chassis dynamometer that can test the performance of light vehicles. The system uses an AC electric dynamometer. Based on the inherent mechanical inertia of the chassis dynamometer itself, it can simulate road resistance with full electric inertia. It can also reproduce the road resistance of the vehicle under test or customize the road resistance. The system is a completely new independent design and development with independent intellectual property rights in accordance with the technical requirements of national standards and European and American certification regulations, referring to the internationally advanced NVH chassis dynamometer Automotive NVH test system. The system uses a fully silent bearing and a dynamometer water-cooling system. The dynamometer itself uses a silencer cover, the foundation cover is soundproofed, and the rotating hub itself is soundproofed with an independent wrapper.

ADAS chassis dynamometer is mainly used in auto-driving tests, simulating the steering function and emergency braking function in the road obstacle avoidance function, and has the functions of automatic steering angle return to zero and steering tunneling.
