Abstract
An adjustable chassis dynamometer includes a fixed roller, an adjustable roller that moves with respect to the fixed roller, and at least one sensor that detects a rotational speed of the fixed or adjustable roller. A belt drive synchronizes rotation of the rollers. The belt drive includes a fixed pulley associated with the fixed roller, an adjustable pulley associated with the adjustable roller, and a tensioner pulley. A belt is provided with an inner surface and an outer surface, and surrounding the fixed, adjustable, and tensioner pulleys, such that each pulley engages the belt's inner surface. The belt drive further includes an idler pulley that moves with the adjustable pulley, is located outside of the belt, and engages the belt's outer surface.
