Abstract
A twin roller type chassis dynamometer includes two coxially arranged load rollers and two coaxially free rollers. The two pairs of rollers are arranged parallel to one another. One of the free rollers includes an outer rotor dynamometer. The rotor of this device is connected by way of a belt drive with one of the load rollers in a manner which produces a step-up gearing and drives the rotor faster than the load roller.
