[0002] Chassis dynamometer is a kind of testing equipment for testing the performance of automobiles without disassembling them. It tests the dynamic performance of automobiles by simulating the road driving conditions of automobiles on indoor test benches, and can also measure emission indicators and fuel consumption under multiple working conditions. Chassis dynamometer simulates the road surface through rollers, simulates the road driving force through power absorption loading devices, and simulates the rotational inertia of automobiles and the inertia of linear motion mass through the rotational inertia of flywheels, so it can conduct complex cycle tests that conform to reality.

[0003] The height of the roller used in traditional chassis dynamometers is difficult to adjust, making it difficult to apply it to different vehicle models for testing. Some existing equipment also proposes to adjust the height, but the stability of the height-adjustable equipment is poor, especially after adjustment, the bottom support force is also weak, and it is easy to malfunction during the motor vehicle testing process.
