Movement of the load roller is measured to determine loaded radial runout of the wheel/tire assembly while the force is applied thereto and a a tire stiffness value for the wheel/tire assembly is provided. A control circuit is responsive to the measured vibration of the wheel/tire assembly to determine wheel imbalance, and responsive to the determined imbalance, the measured loaded radial runout of the wheel/tire assembly, and the tire stiffness to determine the locations and magnitudes of correction weights to add to the wheel/tire assembly to reduce the vibration of the wheel/tire assembly when mounted on a traveling vehicle.

    摘要: A vehicle wheel alignment apparatus includes wheel alignment sensors for obtaining wheel alignment data, including camber, and devices for measuring wheel offset distances. A controller compensates the measured wheel offset distances for the camber of the corresponding wheels. Ride height sensors are included for measuring the ride height of the vehicle at the wheels, and the controller also uses the ride height to compensate the wheel offset distances. Ride height is similarly compensated for camber by the controller. The body angle of the vehicle is obtained from the wheel offset measurements and the wheelbase of the vehicle. The body angle is used to compute dog track angles and correct those angles by applying the body angle to the individual toe angles of the reference axle. Axle offsets are computed and used in front axle cradle adjustment if applicable. The body angle is also used to eliminate the effect of wheel offsets from setback angle calculations. The corrected setback angle is converted into a distance when track width is measured.

    摘要: The brakes of a two-axle vehicle are tested by weighing the vehicle and measuring the braking forces for both axles to determine the actual ratio of front axle braking force to total braking force. The deceleration applied to the vehicle is determined from the weight of the vehicle and the applied braking forces. A nominal preferred value of the ratio of front axle braking force to total braking force is calculated from the determined deceleration and the measured weight of the vehicle. The nominal preferred value varies from test to test with both the actual deceleration and the vehicle weight. For each test, upper and lower limits for the acceptability of the actual ratio of front axle braking force to total braking force are set based upon the computed nominal preferred value. These limits move from test to test with the computed nominal preferred value. The nominal preferred value, the movable limits, and the actual ratio are displayed to the user on a CRT screen. The actual ratio is displayed in the form of a bar on the screen, with the limits and nominal preferred value displayed as non-numeric indicia along the longitudinal axis of the bar.

    摘要: Matching multiple wheel rims and tires based upon runout and force variation measurements using balancing equipment. Centering errors and mounting errors are also reduced or eliminated. The method includes adjusting the rotational positions of the tires with respect to the wheel rims to compensate for wheel rim run-out and wheel/tire assembly force variations. This is accomplished in one embodiment by sequentially mounting a plurality of wheel/tire assemblies on a spindle of a balancer, measuring the rim run-out for each assembly and the force variations for each assembly, marking each tire of each assembly to identify both the individual tire and the rotational position representing the first harmonic of the tire force variation at which each tire is mounted with respect to its wheel rim, removing each tire from its wheel rim, sequentially mounting the wheel rims with tires removed on the spindle of the balancer, measuring the rim run-out for each rim, and visually indicating to a user a preferred matching between the tires and the wheel rims to minimize assembly vibration.
