Abstract: Disclosed in this invention is a flat-belt type VTEHIL test bench for commercial vehicles, including a main bench body and a bench test system. The main bench body is mounted inside a foundation and includes a main bench frame, a bench cover, front axle flat-belt assemblies and rear axle flat-belt assemblies. Each front axle flat-belt assembly is provided therein with a fixed plate, a rotary disc and a limiting mechanism. Each rear axle flat-belt assembly includes a flat belt and flat belt pulleys disposed both within the flat belt at opposing ends thereof. The foundation defines a sector-shaped mounting depression in which the main bench body is mounted, and an iron floor is arranged under the main bench body. This invention can better simulate actual driving surfaces and accommodate two-axle, three-axle, four-axle and other types of trucks or tractors.
