Introducing TruckCam Axle Alignment system
This system is designed for axle manufacturers to pre-align toe-in. The
efficient and durable design of the system allows it to measure toe,camber as well as max turn individually on both sides. As the system is
self calibrating in every measurement cycle, it generates measurement
values with extremely high accuracy.
The system is very easy to install on the flow of an axle assembly line,
as it requires very little floor space. The main components of the system
consists only of two adaptors placed on the axle combined with a PC.

Measurement principle
The traditional way of measuring toe on an axle which is not yet
mounted on a vehicle is to measure the distance from left to right on the
front side and on the rear side of the axle. The difference between thesevalues determines toe-in or toe-out.
TruckCam measures in a completely different way! As the cameras
themselves measure angles, the TruckCam system operates
independent of distances between axle hubs or hub adaptors, by
measuring the individual toe value for each hub. As these measurements
are taken both in front of and behind the axle, any static measurement
errors will be eliminated, hence making the system self calibrating.

Measuring with a TruckCam Axle Alignment system
The operator starts by entering the required data, for example axle
identification number, either by use of a bar code scanner or by manualinput. Camera hub adaptors are mounted on the axle hubs and,
optionally, an inclinometer can be mounted on the axle beam itself or the
axle fixture. This inclinometer is used to check the actual angle of the
axle beam, to give the system a reference plane in which to measure.
The camera hub adapters are positioned with the cameras looking at
each other. By pressing one of the OK-buttons the operator gets the first
measurements of toe-in and straight ahead position. A rough adjustment
can be made if the initial measurement values are far out of tolerance.

The operator rotates the hubs 180 degrees, positioning the cameras on
the other side of the axle relative to their starting position. Again, theOK-button is pushed and the system calculates calibrated measurement
data with high accuracy. Final adjustment of the axle can be made, and
the measurement values are stored in a database. These stored data
can be used for quality control purposes.
Optionally an interface to the torque runner which is used for clamping
can be incorporated into the system. With this feature it is only possible
to finish an alignment process when the required torque is achieved and
the measurement value is within tolerance limits.
Max turn option available
The TruckCam Axle Alignment system is available with the option to
measure max turn as well as toe-in. With this feature included in the
system, the operator first completes a toe measurement. By following
the instructions on the screen, the operator turns the axle to the
maximum right and adjusts as necessary, then turns the axle in the
oposite direction. When both values are within tolerance limits, the
system saves all measurements in a database and the system is ready
for the next axle on the line. This is all completed within a matter
of minutes.

Zero calibration of camera hub adaptor
Zero calibration of camera hub adaptors and inclinometer
The TruckCam Axle Alignment system is self calibrating. To ensure the
accuracy of the measurement plane a zero calibration of the rotationinclinometers in the camera hub adaptors needs to be done on regular
intervals. The system includes software and hardware for this
calibration.

System setup
The system setup is an area of the software where the manufacturerspecifies tolerances and target values for different axle types.
Measurement procedures as well as functions can be set for each
different axle type. This includes for example starting position,
position of the axle, and wether or not to measure max turn.
This part of the system is of course password protected.
