A process for certifying the parameters of the jig 10 may entail calibrating each of ged requirement for michigan the two side spacers, calibrating each of the four stands, and calibrating the side spacer reference piece and the diagonal spacer. The technician (not shown) holds the other end in place to confirm when the jig 10 is assembled to easy fast kid make money ways have a diagonal of the appropriate length.

The technician may check the length of each spacer 15 and 17 with the distance setting device 51, before each assembly of the jig 10, to insure that the length of the side spacers remains unchanged. 5,943, 783 entitled"Method and apparatus for determining the alignment of motor vehicle wheels ;" U. However, with such flexibility in the corners, it becomes necessary to square-up the sitting with crossed leg corners of the rectangular jig 10 during on-site assembly, as will be discussed later with regard to Fig. 0055 The distance setting device 51 essentially acts as a gauge to set and/or confirm the correct, equal length of the side spacers 15 and 17. html#OCR' FooonMouseOver='wipoPop(this, "Note: Text based on automatic Optical Character Recognition processes. The attachment english language phrase spanish apparatus 138 attaches the target 118, carried over the shoulder 120, 120, 124 to wheel 126, 128, 130. 0052 The sphere or ball 87 is free to rotate in the race 85 mounted in the housing 81, and its motion is only constrained by the stub shaft 43 in the through hole 89 interfering with the housing 81. At the middle of the spacer 67, the section 671 has a coupling portion 78 in this case shown as an end of the shaft section machined to provide a slide fit into a coupling member 79 attached to the other section 672 of the shaft. The apparatus also includes two side spacers of equal length. By adding the step of leveling the axles in a traceable manner, these systems may also be certified.

. For example, for the purpose of aligning the front wheels 126, 130, the computer 111 defines a reference plane as that formed by the measured axle location of each of the two front wheels and a point midway between the measured axle locations of the rear wheels 128, 132.

The system uses high-resolution digital cameras. 0069 To take measurements, the mechanic begins by operating the system 100 to take a first set of images of the targets 118,120, 122 and 124. 132, respectively (or to the corresponding plate of car jvc manual owner stereo the jig 10).

The technician can then use the system 100 to obtain readings for toe, camber, and vehicle dimensions from the calibration fixture 10. The outermost portion of each stub shaft has a reduced diameter portion, represented for example by the portion 44 on the illustrated stub shaft 43. Specially, the shaft of diagonal spacer 67 includes two sections 671 and 672. 0007 Another method used to show good calibration of an aligner with wheel-mounted measurement instruments was to take normal measurements denver birth injury attorney free horoscope for all sun sign on one or two calibration bars and determine if total toe and camber values were zero. The spacer 67 is positioned such that the pointed end 71 just touches the inside corner of the axle and end plate (axle 13 and end plate 25 in the example), when placed in either diagonal. The lock nut 61 is tightened against the surface of the member 53, to hold the quasi-stub shaft 55 in the hole through the girder 53. It is intended by the following claims to encompass any and all modifications, variations and applications that fall within the true scope of the present concepts.

The certification method also involves mounting heads of the wheel alignment system at opposite ends of the axles, and operating the wheel alignment system to take a measurement of a parameter of the certification jig.

Typically, length of this spacer is adjustable, for example, to facilitate truing-up the rectangular jig by the iterative procedure outlined above.
The lower end 39 of the set-screw 35 is substantially smooth and is tapered to engage the groove 41 formed in the axle.
5,535, 522 entitled"Method and apparatus for determining the alignment of motor vehicle wheels. Other target designs may be used for wheel alignment, for example with different visually perceptible target elements 136 ; and those skilled in the art will recognize that other aligners 0064 For wheel alignment, one of the targets 118, completely contact free them 120. An example of an attachment apparatus is described in U. 0063 The second major element of the aligner 3D system 100 is a set of four passive target heads, 118,120, 122 and 124 for attachment to the vehicle wheels 126, 128 130 and 132, for example, the same as those shown attached to the jig 10 in Figs. For example, the rolling master was relatively difficult to transport, and it is simply not practical to have such a master at every tire back cant get i wait store or auto dealership that does wheel alignments. 16, each target 118,120, 120, 124 includes a target body 134, target elements 136, and an attachment apparatus 138.
This method involves checking length of two side spacers of a certification jig for proper length, and assembling two equal-length axles and the two side spacers, to form the certification jig with a parallelogram shape. Other ends and shaft configurations may be used to form the diagonal spacer. A tape measure may be used to check dimensions of the jig 10 on-site, and if so, the certification of the jig 10 may include calibration of the tape measure. showing the actual errors or percentage differences of one or more measured values from the known value (s) for the certification jig 10, for example, to help with re-calibration of the aligner system.

Each support stand 19 consists of a horizontal base plate and a vertical plate with the"V"notch formed in its upper portion. 0059 The diagonal is the longest dimension of any rectangle, and in the system of Figs. Then, after determining the accuracy of the wheel aligner, the jig is disassembled for transport or storage.

As shown, last minute holiday florida the upper portion of the stand 19 includes an opening 31 for receiving the axle. Hence, any solution should utilize portable or collapsible certification equipment so as to be relatively easy to transport to or store at shop sites.

The advantages of the present subject matter may be realized and attained by means of the methodologies, instrumentalities and combinations particularly pointed Brief Description of the Drawings 0015 The drawing figures depict one or more implementations in accord with the present concepts, by way of example only, not by way of limitations.
1, but showing the use of the diagonal spacer to measure and adjust one of the diagonals of the jig and 0027 Fig. 0054 The box girder 53 has holes drilled at opposite ends thereof, to achieve a precise, fixed distance therebetween. The clamps and targets are attached to the end plates. 3 is a detailed view showing a stub shaft of an axle extending outward from an end plate attached to the axle.
0072 Once all measurements are complete, the computer 111 generates a visual output of the measured alignment parameters and/or provides data relating to adjustments needed to bring the alignment parameters back to original manufacturer's specifications. There are three buttons under the horizontal base plate, which provide a stable mounting on the lift racks 140. Essentially, each camera forms an image of objects within its filed of view, which in operation includes one or more targets ; and in response to the image each camera 0062 In an exemplary system 100, each light emitter takes the form of a strobe comprising an array of flashing red LEDs mounted around the aperture of one of the cameras. During each such iteration, the technician supports the diagonal spacer 67 on the stand 69 with the knife edge positioned in one corner as shown for example in Fig. A manufacturer may calibrate the wheel alignment system, as part of the manufacturing and/or installation process, and the system may be re-calibrated from time to time to compensate for wear and tear. The targets 118,120, 122, 124, once attached to the wheel rims, are then oriented so that the target elements 136 on the target body 134 face the camera in the respective module 110 or 112. Although other releasable coupling may be used, the example uses a slide fit arrangement with a bolt to secure the parts in place at the coupling.

Front wheel alignment calculations then are referenced to this individually measured plane.
