Creative Systems - Globally: Knorr-Bremse at InnoTrans 2016
“The main advantages of networking are uncompromising levels of safety, maximum reliability and low life cycle costs,” says Klaus Deller, Chairman of the Executive Board of Knorr-Bremse AG and responsible for the Rail Vehicle Systems division. Under the title of Connected Systems, Knorr-Bremse provides complete, standardized solutions from a single source that generate added value for vehicle manufacturers and operators in terms of time, technology and cost.
Carefully matched hardware and software for sub-systems, equipped with standardized interfaces and tested prior to delivery, enable vehicle manufacturers to benefit from improved project planning, simplified homologation procedures and lower costs. Diagnostics can be carried out on the various vehicle sub-systems using a standard service tool, which means that commissioning and servicing are also significantly speeded up. The result is greater vehicle availability and lower operating costs. The basis throughout is a scalable performance range based on a single principle: the more extensive the networking, the greater the ultimate benefit.
Hall 1.2b, Booth 104: Knorr-Bremse’s range of products and services
At its main booth, Knorr-Bremse has brought together a wide range of different products and services from various parts of the company. In the field of air supply it is showcasing an intelligent air control system that saves operating costs and reduces noise levels for passengers and nearby residents by varying compressor speed according to the vehicle’s operating status. Thus, for example – provided sufficient compressed air is available – the compressor speed is reduced when the train enters a station or is parked in readiness at nighttime. Smart control using the latest generation of VVT oil-free compressors avoids the need for auxiliary compressors.
Part of the system is the VV90T compressor, which is capable of a cold start at temperatures down to minus 50° Celsius; another product is the new Intelligent Air Dryer, which saves air and energy by adapting its operation to environmental conditions; and a further key element of the Intelligent Air Control system – the converter – is supplied by Knorr-Bremse’s PowerTech brand.
In the field of brake control the company is showcasing a large number of systems that ensure reliable braking under a wide range of ambient conditions: The electro-pneumatic EP-60 braking system for freight train applications not only significantly cuts braking distances but also reduces critical in-train forces. An integral part of the system is the Smart Car application, which uses the existing EP-60 communication network to monitor the loading and unloading hatches and to open and close them.
The Safe Sand sanding system and the new MGS3 wheel slide protection system improve wheel-rail adhesion even under extremely slippery conditions and ensure short braking distances. In addition, the EP Compact braking system with integrated KKL-2 compact control valve is a similarly high-performance, flexible brake control system for passenger car applications that can be configured for all types of high-speed trains and multiple units. The modular CCB-3 braking system family for locomotive applications is equipped with standardized interfaces that avoid the need for redesigning the locomotive if it is to be used in a market with a different standard.
Bogie equipment on show includes the WZT brake caliper unit, the CFCB Light compact freight car brake, MORE 900 (Modular Rigid Magnet) and the GRIP electromagnetic track brake end piece. The WZT is the next generation of compact brake calipers and is not only resilient to high-pressure cleaning but also lighter and more compact. CFCB Light is a compact freight car brake for particularly weight-critical applications. The highly effective MORE 900 electromagnetic track brake has been specially developed for compact installation envelopes in light rail vehicles.
The growing hydraulic segment is represented by the HS1A30 brake caliper with automatic wear adjustment and completely sealed bearings. The new hydraulic levelling cylinder adjusts the entrance system to the platform height, making it easier for passengers with restricted mobility to board the train. The GRIP Magnet is an application for standard-gauge trains that reduces energy consumption by 5% per kilo newton of braking force.
Reliable, rapid boarding and disembarking is essential for efficient train operations, so the focus for Knorr-Bremse’s IFE division in developing the new SNAKE entrance system for mass-transit systems was on robustness and rapid opening and closing. The system is specifically designed to operate in restricted spaces and features a sliding door with triedandtested components from the IFE RLS range that have successfully undergone decades of field-testing. The ultra-flat, lightweight entrance system can deliver opening and closing times of less than two seconds even when installed in a restricted space with opening widths of more than 1,600 mm. This means shorter stops in stations and greater train frequency. The robust drive system remains within the vehicle at all stages of door operation, and the lubricant-free spindle drive and sealed bearings reduce maintenance requirements.
Efficiency is the name of the game when it comes to the adaptive HVAC system for LRVs on offer from Knorr-Bremse’s Merak brand. With its compact design, the system is easy to install, offers an excellent weight to performance ratio – weighing in at a mere 500 kg and generating an output of 45 kW – and can be easily networked with other Knorr-Bremse systems. It also adjusts its output automatically to the volume of passengers in the vehicle.
Knorr-Bremse subsidiary Microelettrica is showcasing the IR4000, a new, even lighter, high-speed circuit breaker for a wide variety of rail applications. The new Cooling Unit System for converters has a compact design with a 20% reduction in size compared with similar products. It also has high levels of corrosion resistance and successfully passed a 1,000-hour salt mist test as part of the ISO 9227 certification process.
RailServices, Knorr-Bremse’s aftermarket division, is also presenting its products and services on the main Knorr-Bremse booth. Here the focus is on an expanded services portfolio and solutions for all Knorr-Bremse products and systems throughout their entire life cycle with operational reliability, short downtimes and low repair costs. RailServices offers customized service packages, efficient spare parts logistics and flexible servicing by highly qualified local technical personnel. One central theme is modernization, with groundbreaking improvements to individual components as well as systems modernization for a wide variety of vehicles aimed at extending service life and reducing life cycle costs.
In terms of products, RailServices is presenting Knorr-Bremse iCOM® – an innovative platform for the digital railroad age. With its associated apps this retrofittable system enables on-board systems to be networked and linked to the trackside. Whatever the vehicle platform, operators can carry out cost-effective, condition-based or preventive maintenance on their vehicles as required (iCOM Monitor). The iCOM Assist app helps the driver maximize energy efficiency and reduce wear and tear while still adhering precisely to the timetable. And iCOM Meter monitors and records the train’s actual power consumption in real time, enabling the operator to ensure accurate billing and use the data to identify potential for further reductions.
