The RoaDyn V6HT force and moment measuring wheel is a turnkey system and does not require any modification to the vehicle.

The RoaDyn V6HT force and moment measuring wheel is a turnkey system and does not require any modification to the vehicle.

It accurately provides the longitudinal, the lateral and the vertical forces, and in addition the measured moments in the respective direction, introduced into the wheel under driving conditions or on a test bench.

The unique design of this sensor results in a complete decoupling of the individual forces and moments; this is why it is specially suited for measurements with heavy trucks or in general high loads.

The signals measured are conditioned on the wheel and transmitted by telemetry.

An antirotate bracket is attached to the fender or the stub axle, defining the wheel rotation versus the vehicle coordinate system by an angle sensor.

Electronics inside the vehicle perform an online coordinate transformation.

A reference plane can be preselected for the measured moments.

Output signals are analogue for used with today's standard date acquisition units.

In multi-axial test facilities the sensor is mounted via a simple adapter ring to the load frame.
