摘要

ABSTRACT A digital toe-measurement system for checking and aligning tractor wheels toe-in and comprising: a movable base frame; a support rod on either side of base frame; target plates fixed on support rod ends; a swivel point at the center of the support rods for adjusting the wheels toe-in; a lead screw connecting the support plate swivel points for the swiveling movement of swivel joint; a distance measurement sensor each fixed on the target plate it; an electrical panel for connecting the distance sensors to the controller and the electronic display; an electric motor for moving the lead screw to swivel the support rods and connected to a battery-operated electrical supply; an electronic display unit; and a programmable logic controller; wherein the base frame supports all above components and sub-assemblies and is dimensioned to be easily slid under/removed from under the tractor axle for tractor wheel toe-measurement and adjustment. A method for electronic toe-in measurement and adjustment is also provided. FIGURE 6a.
