Abstract
A device for restraining the driving tires of a vehicle on a chassis dynamometer which includes sidewall rollers that position themselves automatically as the vehicle approaches the dynamometer and which lock in place before the dynamometer test begins. The restraining rollers are rotatably mounted on one or more carriers that are initially free to move right or left to accommodate the position of the vehicle's tires. When the latter are satisfactorily aligned with respect to the dynamometer rollers, the movable carriers are locked in place, restricting the lateral movement of the driving tires during the test on the dynamometer. The invention is intended particularly for dynamometers in exhaust emission testing facilities, including garages and service stations, where a low-cost, yet robust, vehicle restraint system is desired.
