„ Briefly from Around the World RTR 4/2010 48 The callipers for the axlemounted brakes in the braking system for the new Shinkansen E5 are equipped with INA-brand needle bearings, drawn-cup needle bearings, internal rings, axial suppor t and rotating washers and axle needle rollers and cages Dirk Lehmbeck (left), director of product management at MercedesBenz Special Trucks, photographed handing a Unimog U 400 for use on roads and rails to Kay Euler, director of production at DB Regio. The ceremony took place on 23 September at InnoTrans 2010 in Berlin Solution for the application of mobile railhead lubrication Igralub and Railtec Systems from Switzerland, bring a new development onto the market with the name of TOR Control. Unlike the earlier, simple systems for the detection of curves TOR Control is a computer that receives signals from GPS and other sources, and controls and triggers the spray commands on the basis of predefined criteria. This new system guarantees a predetermined and precise use. Operationally relevant inputs are also registered, and can be redefined in a manner specific to the project. The TOR Control detects the precise application locations. This takes place in both the open air and in tunnels. The definitions of the precise spraying locations and their length are achieved from a mapping that is directly created during a teach-in run using a laptop in the vehicle. The setting of the spray command takes place using a simple software that is a component part of the supplied operational software. The exact positions will be entered into the route plan by simply setting the start and end points. Modifications or the addition of new spray locations are possible at any time and can be carried out by the operator himself. „ TOR Control Needle bearings for the Shinkansen The management of the Schaeffler Group’s industrial sector has succeeded for the first time in obtaining a foothold in the Japanese high-speed train with a series of components for the braking system „ INA of the new Shinkansen E5. The new class of Shinkansen is going to be operating on the line between Tokyo and Shin Aomori starting in December 2010. Increasing the maximum speed on this line from 275 km/h to 320 km/h has made it necessary to install a new powerful braking system, which has been developed by Knorr-Bremse. The callipers for the system’s axlemounted brakes are equipped with INA-brand needle bearings, drawncup needle bearings, internal rings, axial support washers and rotating washers as well as axial needle rollers and cages. The drawn-cup needle bearings have a layer of Corrotect®N to protect them against corrosion. Corrotect®N is an extremely thin chromium-VI-free surface coating, which has been developed by the Schaeffler Group and provides protection against corrosion and, in particular, protects the running surfaces of seals against subsurface rusting, which may be caused by condensation, rainwater or waste water.

Headlub is biologically degradable and water-repellent. The amount sprayed in each case amounts to an average of 0.25 cm3, corresponding to a theoretical film thickness of 0.083 μm. Igralub offers all necessary system components as a Total Service Provider. Customer specific project development, commissioning and maintenance control are therefore all available from a single source. This service makes it possible for larger metro and tram operators, as well as railway operators, to introduce a comprehensive railhead and wheel flange lubrication. Igralub offers a simple test unit as a startup project. Upon the presentation of TOR Control at the InnoTrans 2010 Igralub has received an immense interest for it. There are already major projects in progress in Europe, Asia and North America, such as those in Brussels, Toronto, and different places in Switzerland and Germany.

The U 400, which is fitted out with railway equipment from Zwiehoff/Zagro, is going to be used by DB Regio in North Rhine-Westphalia at its depot in Aachen, for the purposes of shunting, train formation and train preparation as well as for towing trains through the washing unit. The rail/road Unimog is an ecologically reasonable and economic alternative to a shunting locomotive on account of its low fuel consumption (of only roughly 5.5 litres of diesel per hour of work). The Unimog is powered by an environmentally friendly Euro-5 engine, includes SCR equipment and carries a green disc showing that it is in the best finedust category, which means it is already equipped to be allowed to operate in the zone with the strictest environmental constraints in the Aachen city centre. One of the essential system advantages for using the Unimog as a rail/road vehicle is inbuilt in its compact axle dimensions. The Unimog U 400 is equipped with special wheel rims and tyres and can thus be driven along rails using its own road wheels, there being no need for it to have a separate transmission system for its railway application. Thanks to the high friction value between rubber and steel, the Unimog is able to move very heavy trailing loads along the rails. It has a dependable rail-guidance unit that „ Mercedes-Benz Special Trucks is lowered hydraulically into its working position whenever required, and the Unimog needs a level stretch of only five metres or so to be able to leave the railway track (which is a simple manoeuvre) and to continue by road to its next place of deployment. Other features that predestine the Unimog for running on rails are its permanent all-wheel drive with an inter-axle lock as well as separate differential locks for its front and rear axles, a torque-converter clutch for jolt-free starting and for managing heavy trailing loads as well as a gearbox with eight forward and eight reversing gears, enabling it to run at up to 50 km/h in both directions on rails – all of which are parts of its standard equipment. The Zwiehoff/Zagro railway equipment installed on the vehicle for DB Regio is comprised, inter alia, of a braking unit for railway wagons for 52 axles (800 tonnes), lifting and swivelling coupling rods at both ends and a wireless remote control for professional shunting in a driver-only operation. The Unimog is also authorised to run on the tracks managed by DB Infrastructure and, for this purpose, it is equipped with railway-type head and tail lights, digital two-way radio and an automatic vigilance device. A speed governor especially developed for DB Regio enables it to tow railway vehicles at a constant speed of roughly 1 km/h. This helps produce optimum cleaning results when it is used for towing trains through washing units. (uh) www.mercedes-benz.com
