General
ViaFriction is a one-wheeled friction measuring device pulled by a vehicle. Its main task is to measure the friction of the pavement surface, in both winter and summer conditions. The friction between the measuring wheel and the surface is continuously measured, while a unique measuring technology, developed and patented by ViaTech, ensures that the data is stable and reliable, even under volatile conditions. This reduces the need for calibration significantly.
The device has very few moving parts — which makes ViaFriction almost maintenance free. Over 175 ViaFriction devices have been delivered since 2006; all of them are still in use, which is a testament to their durability. ViaFriction utilizes an electric braking system to be able to measure the friction coefficient. This system doubles as a heating device, keeping the friction measuring device free of ice and snow under winter conditions.
Through rigorous testing, it has been proved that ViaFriction has superior characteristics compared with other friction testers on the market. ViaFriction gives repeatable measurements for various conditions and retains its calibration over time. Our customers range from universities to road authorities and private companies around the world.
The device will run freely behind the vehicle under transport. It may also be delivered with an electric lifting device, which will hover ViaFriction over the pavement surface when not in use. See the images to the left for an illustration of this lifting mechanism.
ViaFriction is normally delivered as trailer solution. The device can run using batteries, but may also be connected via 12V/40A connector for battery charging. ViaFriction communicates with the computer in the car using a wireless link or an Ethernet cable. The trailer solution makes the friction meter independent of one specific vehicle and does not require vehicle-specific installation.
One of the first friction devices on EL/Hybrid vehicle.
