    摘要： A system for measuring caster trail of a wheel. The system comprises position sensing devices for sensing positional signals of the wheel and a data processing system configured to couple to the position sensing devices. The data processing system receives signals from the position sensing devices and determines spatial characteristics of a steering axis of the wheel, a reference plane and the center of a wheel. The system then determines the caster trail based on the spatial characteristics.

    摘要： In a vehicle alignment system an optical sensing mechanism is structurally coupled to a vehicle supporting lift for movement in unison with the lift so that the field of view of the sensing mechanism encompasses a wheel of a vehicle positioned on the lift during lift movement. Sensing modules may be selectively placed so that they are in correspondence with the vehicle wheel base. Modules may be deployed to extend outwardly from the lift, for viewing the wheel during an alignment procedure, or retract to a adjacent the lift for stowing. A protective cover extends above the sensing modules in the retracted position.

    摘要： A diagnostic method and system for determining an operational status of a multiple-link steering system for steering an object attached thereto. The system includes a position determination system for obtaining positional signals related to a steering system, and a data processing system to calculate positional parameters of the steering system based on the positional signals. The data processing system includes a data processor for processing data and a data storage device for storing data. The data storage device bears instructions upon execution by the data processor causing the data processing system to receive a first, second and third positional signal of the steering system when the object being steered to a first, second and third steering angle respectively. The data processing system calculates a first positional parameter for the steering system based on the first and second positional signals, and a second positional parameter for the steering system based on the second and third positional signals. An operational status of the steering system is determined based on the first and second positional parameters, and reference positional parameters.

    摘要： The present disclosure provides a method and system for determining symmetry and Ackermann geometry status of the steering system of a vehicle. A system according to the disclosure determines symmetry of the steering system based on toe angle differences of the steerable wheels. Thus, no specification is required for determining symmetry of the steering system. A system according to the disclosure determines symmetry of the steering system based on normalized toe angles. Consequently, the steerable wheel does not have to be positioned at a specific angle. Additionally, the present disclosure determines symmetry in the steering system of a vehicle without requiring turning steering wheels through a large angular range. Hence, technician efforts in steering the wheel are reduced. The disclosure also provides an improved alignment procedure that implements determination of symmetry of the steering system into the alignment procedure. The present disclosure provides a novel machine-implemented procedure to determine Ackermann geometry status of a steering system based on theoretical Ackermann angles.

    摘要： A wheel clamp attaches to a vehicle wheel for performing a wheel alignment on the vehicle. The wheel clamp has a body for supporting a target or measuring head, and three extendable arms slidably mounted to the body. Each arm has a gripping portion for gripping the tire's tread surface and a sidewall contact portion for contacting the tire sidewall such that the clamp body is substantially parallel to the vehicle wheel and the wheel clamp has no contact with the rim. A self-centering linkage has enmeshed gears and link arms respectively connecting the arms to the gears, such that when the gears are rotated, the arms simultaneously proportionally slide relative to the clamp body, so the gripping portions of the arms engage and grip the tire tread surface and tighten the clamp onto the tire, while the sidewall contact portions of the arms contact the tire sidewall.

    摘要： A lightweight wheel clamp assembly is provided for attaching to a vehicle wheel for performing a wheel alignment on the vehicle. The assembly comprises a first bracket for engaging the vehicle wheel; a second bracket for engaging the vehicle wheel; a handle rotatably mounted to the second bracket; and a rod having a threaded portion and an attachment portion near a first end of the rod. The first bracket is attachable to the attachment portion of the rod, and the handle is threaded to engage the threaded portion of the rod, such that when a user grasps and rotates the handle, a distance between the first and second brackets can be adjusted to rigidly attach the wheel clamp assembly to the vehicle wheel.
