Description
Technical Field

[0002] The chassis dynamometer is an indoor bench test equipment used to test the vehicle's dynamics, multi-condition emission indicators, fuel indicators and other performance. The vehicle chassis dynamometer simulates the road surface through a roller, calculates the road simulation equation, and simulates it with a loading device to achieve the simulation of various vehicle working conditions. The traditional measurement of the vehicle's transmission system resistance loss power, vehicle chassis output power, etc. requires the wheels to be placed on the top of the chassis dynamometer's drum before the vehicle is tied. The chassis dynamometer's centering mechanism ensures that the tires can effectively and safely stop in the middle of the roller when the vehicle is performing tests such as starting acceleration, overtaking acceleration, maximum speed, and climbing ability.
