    ALIGNING TORQUE, PARALLEL
    The vehicle chassis is held fixed by the K&C rig center table while ground plane torques are applied through each of the four tire contact patches. ‘Parallel’ indicates that torque is applied through each wheel in the same direction (i.e. all torques clockwise, and/or all torques counter-clockwise). Corresponding loads, displacements, and orientations are measured at each of the four wheels.

    ALIGNING TORQUE, OPPOSED
    The vehicle chassis is held fixed while ground plane torques are applied through each of the four tire contact patches. ‘Opposed’ indicates that torque is applied through each wheel in opposing directions at each axle. While an aligning torque parallel test will capture the effects of left/right suspension connectivity components (such as the steering system, subframes, anti-roll bars, etc.), the opposed test, by nature of applying equal and opposite torques to left and right side suspensions – and thus “shorting out” any right/left connective components, will capture the effects of an individual suspension corner. Corresponding loads, displacements, and orientations are measured at each of the four wheels.

    ALIGNING TORQUE, SINGLE WHEEL
    The vehicle chassis is again held fixed while aligning torque is applied to wheels on one side of the vehicle only.

    Here are some characteristics that are measured in an Aligning Torque Test:

    • Toe Stiffness
    • Tire Aligning Stiffness
    • Hysteresis
    • Steering Torque Feedback
