MOTOR VEHICLE ALIGNMENT TECHNOLOGY

Abstract

An alignment system for aligning the wheels of a vehicle. The alignment system measures caster and camber of the treat wheels of the vehicle. The system includes four alignment heads, each alignment head having a laser, a target, and a transmitter/receiver. A rim clamp communicatively couples each alignment head to the wheel of the vehicle. A turn plates is positioned below each front wheel of the vehicle.

Claims

1. An alignment system for measuring caster and camber of the front wheels of a vehicle, comprising: a. four alignment heads, each alignment head including a laser, a target, and a transmitter/receiver; b. a rim clamp for communicatively coupling each alignment head to the wheel of the vehicle; and c. two turn plates, each turnplate adapted to be positioned below a front wheel of the vehicle.

DETAILED DESCRIPTION

[0037] This invention provides an alignment system for aligning two or four wheels of a vehicle, such as an automobile, truck, van or the like. The system works in a variety of service environments including a drive-on alignment rack, twin post lift or garage floor. The system is useable to perform a variety of tasks, including but not limited to measuring and recording before and after measurements, automatically calculating camber, recording caster and tow, and calculating thrust angle. The system displays and records measurements in fraction and decimal form, create and save records, and print and export such records.
