role. The latest brake control system also carries out condition monitoring of bearings, gearbox components<br />
and wheels – at only a minimal increase in cost and complexity.<br />
The COMORAN system monitors wheel bearings, analyzing their vibration frequencies and relaying<br />
data on their condition either to an onboard computer or via Ethernet to a central server. Using information<br />
based on experience with residual operating life, this enables condition-based maintenance of<br />
components to be carried out without making any concessions in terms of availability and safety. Intelligent<br />
use of mechatronics enables temperature and acceleration measurement to be integrated<br />
into the existing sensor system.<br />
A new system<br />
monitors wheel<br />
rotation and prevents<br />
critical situations such<br />
as derailment.<br />
Following several years of field testing on a vehicle operated by Munich Metro, the system was officially<br />
launched in <strong>2012</strong>. The first commercial order has already been received, with COMORAN scheduled<br />
for installation in a Brazilian urban train in 2013. The flexibility of the system not only enables the wheel<br />
bearings to be monitored – it also detects critical situations such as derailment.<br />
<strong>Knorr</strong>-<strong>Bremse</strong> develops new windscreen wiper<br />
and washer system for high-speed applications<br />
PHX (Pneumatic High End NeXt Generation System) is a new wiper and washer system specially designed<br />
by <strong>Knorr</strong>-<strong>Bremse</strong> to cope with the forces acting on the large front windscreens of trains travelling<br />
at high speeds. System testing for the first application started during the year under review.<br />
The electro-pneumatic system is the latest generation of the tried-and-tested wiper and washer system<br />
that <strong>Knorr</strong>-<strong>Bremse</strong> has been producing for various high-speed applications over the last 15 years.<br />
It combines several subsystems and is therefore less complex than its predecessors. PHX is also smaller,<br />
lighter and more compact.
