Abstract:
A method for measuring and compensating steered-angle sensitive wheel alignment angle and distance measurements for the effects of steering a wheel from a straight ahead position, thereby enabling an operator to carry out a vehicle wheel alignment angle adjustment without having to maintain a wheel in a straight-ahead steered condition during an alignment angle or distance adjustment, or to require the operator to continually return the wheel to the straight-ahead steered condition to acquire updated measurements of an alignment angle or distance currently being adjusted.
Abstract:
An intuitive and context sensitive system facilitating the proper identification and service of a vehicle undergoing a vehicle service procedure. The system is configured with a mapping of relevant vehicle identification assistance data or vehicle specific information to one or more selection locations in the user interface of a vehicle service software application. The mapping identifies the availability of additional vehicle identification assistance information, vehicle specific functional applets, and the context within the vehicle service software application at which the additional vehicle identification assistance information or vehicle specific functional applets are relevant. The additional vehicle identification assistance information or applets are maintained external to the vehicle service software application, permitting the additional vehicle identification assistance information and applets to be updated, changed, or replaced without altering the vehicle service software application.
Abstract:
Methods for facilitating controlled movement of at least one vehicle wheel. The methods include the step of presenting a display of information, such as by visual display or audible signals, to an operator to direct a manual controlled-speed movement of the vehicle wheel. The controlled-speed movement may be a rotational movement such as during a wheel alignment rolling compensation procedure, a steering movement, such as during a vehicle wheel alignment angle measurement procedure, or a rotational movement such as during a wheel assembly measurement procedure on a vehicle wheel balancer.
Abstract:
A vehicle wheel balancer system with a controlled centering chuck for automatically centering a wheel assembly about a balancer spindle shaft, and a powered clamping device configured to provide a first clamping action which facilitates centering of the wheel assembly on the balancer spindle shaft, and a second clamping action to secure the wheel assembly on the balancer spindle shaft during rotational wheel balance measurement procedures.
Abstract:
A vehicle wheel alignment system with a wheel alignment angle sensor adapted for removable attachment to a vehicle wheel assembly, incorporating a two-dimensional imaging array at an orientation relative to a sensor mounting axis. The two-dimensional imaging array is configured to form an image of light from one or more remote light sources. The horizontal and vertical position of the images on the two-dimensional imaging array are representative of at least two angular orientations of the wheel alignment angle sensor relative to the remote light source, which is preferably coupled to an adjacent vehicle wheel assembly.
Abstract:
A vehicle service system configured to measure and utilize lateral force information associated with a set of vehicle wheels to provide an operator with a suggested placement for the individual vehicle wheels about the vehicle, such that the effects on the vehicle handling caused by the lateral forces are minimized.
Abstract:
Apparatus and method for determining the alignment positions and orientations of vehicle wheels includes optical targets mounted on the wheels and optical targets mounted in a fixed relationship with respect to the surface on which the wheels are disposed. Video cameras are used to obtain images of the various optical targets and a computer is responsive to the images of the targets to determine values of wheel alignment parameters of the vehicle relative to said surface on which the vehicle wheels roll. The surface on which the wheels are disposed may be an automotive lift, and apparatus is disclosed for keeping the optical targets in the same position in the field of view of the camera(s) whether the lift is in its rest or in an elevated or reclined position.
Abstract:
A brake lathe includes a set of rotor cutting bits and a drum cutting bit. Each bit has associated therewith an encoder for measuring the displacement of the bit. The displacements as measured by the encoder are used by a controller to digitally determine various parameters such as absolute thickness of a rotor being lathed, the depth of cut into the rotor, absolute internal diameter of a drum being lathed, and the depth of cut into the drum. The lathe includes a display for displaying the values of the parameters. The lathe includes a calibration mode for calibration of either the rotor cutting or the drum cutting function of the lathe as desired.

Abstract:
A method of operation of a twin roll casting apparatus to produce thin gauge sheet metal at high-production rates. The method includes simultaneously adjusting various operating parameters, such as the roll speed, tip position, roll gap, molten metal input temperature and exit strip tension. In an iterative fashion, the strip gauge is reduced in steps while increasing the speed of the rolls and pulling the tip back out of the roll bite. In conjunction with the aforementioned adjustments, the temperature of the molten metal input to the feed tip is gradually reduced to ensure proper solidification at higher speeds. A set of pinch rolls closes on the exit strip at a certain gauge thickness to apply a drag to the strip in order to ensure proper coil wind-up tension.
