Heavy-duty vehicle chassis single-wheel dynamometer based on cylinder bead belt transmission

The invention belongs to the technical field of automobile chassis power measurement, and particularly relates to a heavy-load vehicle chassis single-wheel dynamometer based on cylinder bead belt transmission. The invention provides a heavy-load vehicle chassis single-wheel dynamometer based on cylinder bead belt transmission, and aims to solve the problem of low dynamometer precision of a chassis dynamometer in the prior art. A heavy-load vehicle chassis single-wheel dynamometer based on cylinder bead belt transmission comprises a base, and a dynamometer table with multiple degrees of freedom relative to the base is arranged on the base. The dynamometer comprises a supporting plate, two rollers are rotatably connected to the supporting plate, a power belt is arranged between the two rollers, the supporter is fixed to the supporting plate, balls are arranged on the supporter, the balls are rotatably connected to the supporter, and the balls are uniformly distributed on the supporter; the roller, the balls and
