Wheelset Diagnostics Systems

HEGENSCHEIDT ARGUS®S - Stationary wheelset diagnostics for overrun speeds up to 160 km/h

ARGUS wheelset diagnostics systems from HEGENSCHEIDT include automatic monitoring of wheelsets in drive-through operation using modern, economical measuring methods and documentation in a database. The system makes it possible to monitor the ever tighter tolerances and operating limits required for increasing speeds and improving safety, ride comfort and operational reliability. The modular design of the ARGUS wheelset diagnostics system allows economical adaptation to the customer's measurement requirements.

Application and use

ARGUS®S is a stationary wheelset diagnostic system for rail vehicle wheels on the track. The system reliably measures the wear condition of the wheels even at speeds of up to 160 km/h in through-track operation. The system is specially designed for installation and operation on heavily used routes and does not require any track modifications, i.e. the existing track is retained and the system is simply clamped to the track. The vehicles are automatically identified as they pass through the measuring section and the wheels are measured simultaneously at several points using the light-section method. All relevant measurement data is archived in a database. This allows the operator to continuously monitor his wheelset fleet online and without loss of time. The wear characteristics are determined based on the measured values and form the basis for an economical, environmentally friendly and safety-conscious maintenance.

Added value

24/7 fully automated wheel geometry monitoring
Measuring operation at overrun speeds up to 160 km/h
Archiving of all measurement data in a wheelset database with full online access
High track availability due to short installation time, low maintenance requirements (annually), and replacement of the measurement technology during breaks in operation (patented offline calibration)
No direct rail reference of the measurement technology when evaluating the profile of the light sections - A short, straight piece of track section is sufficient for installation
No interference with the permanent way approval and large distance to the clearance gauge
Low measurement uncertainty with up to 99% yield
Precise and online knowledge about the condition of all wheelsets with history and wear condition
In conjunction with the HEGENSCHEIDT TWM, improved workshop organization and logistic preparation
Proof of the extended measurement uncertainty under process conditions in accordance with VDI/VDE/ DQG 2618 sheet 27, VDA 5/ GUM by an accredited calibration
laboratory

Function

ARGUS®S consists of the Identification, Diameter, and Profile modules. The profile contours of the treads, the diameter of both wheel discs, and the distance between the wheel backs are recorded and measured during the pass. The geometric parameters of the wheel set, such as flange height, flange thickness, wheel back distance, radial runout, drum width, and diameter, can be determined from the recorded wheel profile. In addition, the outer side of the wheel is recorded, including the gauge groove (characteristic groove) and roll-on. The system measures in both directions. Network coupling allows the system to be integrated into existing IT systems or the HEGENSCHEIDT TWM system. The data interface is designed as a web service and can be operated via an Internet browser.
