Abstract
An improved mechanical flywheel assembly for a chassis dynamometer. The flywheel assembly includes a plurality of flywheels journalled to a stationary shaft located within a cylindrically-shaped drum that is directly coupled to the rollers of the dynamometer so that the drum rotates at the speed of the rollers. Each of the flywheels has an air-actuated clutch mechanism secured around the periphery of the flywheel so that upon actuation, the clutch mechanism expands radially sufficiently to engage the inner wall of the drum and thereby cause the associated flywheel to rotate with the drum. Means are disclosed for controlling the selective actuation of the various clutch mechanisms to thereby selectively control which of the various flywheels are engaged.
