LAUNCH                       KWA-300 3D Wheel Aligner                              Introduction

Fig.1.9 

 

The data collecting system consists of 4 cameras with 
high resolution and 4 targets. The left and right cameras 
capture the images on the left and right targets, and 
transmit them to the data processing system via the 

image collector. The targets are attached on the wheel 
rims via wheel clamps. So the geometrical relationships 
among 4 wheel rims are calculated according to the 
images captured by cameras from the targets and 
further to confirm the aligning parameters of the wheels.   
 

The data processing system is the main unit of 
KWA-300 3D. It consists of a computer, power supply 
system and interfaces. Its function is to execute the 
operation commands, process the data and display the 
information together with the original data of vehicle 

manufacturer. It also gives instructions for making 
adjustment to the vehicle and print out corresponding 
report. 
 
The wheel aligner compares the measured results with 

the original data of vehicle manufacturer and gives 
instructions to the user for adjustment, so its databank 
should contain enough information. KWA-300 3D Wheel 
Aligner databank contains over 20,000 models 
alignment data, and user can also add new vehicle 

wheel alignment data into the databank when 
necessary.
