ABSTRACT:
A mounting fixture assembly allows the attachment of a laser light emitting device—in this case a laser level—used along with a light reception board to determine thrust, toe, and camber measurements of motor vehicles. The mounting fixture provides a means of surface mounting the laser device to the rims of the wheels of motor vehicles without the need for any physical clamping or attaching devices used at the rim, wheel, or tire of a vehicle in conjunction with a laser emitting device support fixture. The mounting fixture permits the surface mounting of the laser device to wheels having camber angles within a normal range of deviance (+/−10° approximately). The fixture assembly maintains surface contact of the laser device throughout the adjustment process. The fixture allows for the radial rotation of the light emitting device facilitating the determination of measurements used in the calculation of toe angles.
