Knorr-Bremse at InnoTrans 2018: Focus on customers, passengers and society

▪ Emphasis on global megatrends: Urbanization, eco-efficiency, digitization and automated driving
▪ Solutions for key market drivers: System connection, life-cycle efficiency, transport capacity and ecodesign

Knorr-Bremse, the world market leader for braking systems and a leading supplier of other subsystems, is present again this year at InnoTrans, the world’s leading trade show for the rail industry, in Berlin.

“With booths in four of the halls, Knorr-Bremse is presenting itself as a pioneer in mobility and transportation technologies, in particular one with an innovation lead in connected systems”, says Klaus Deller, Chairman of the Executive Board and Executive Board Member responsible for the Rail Vehicle Systems division. “Under our trade show motto of Systems.People.xConnected, we are giving more space to the connectivity trend and focusing on customers and passengers, but also on environmental and social aspects. With our products and systems, we are providing solutions for the industry’s key market drivers: System connection, life-cycle efficiency, transport capacity and ecodesign.”

System connection
Thanks to its high level of systems competence and wide-ranging product portfolio, Knorr-Bremse enables its customers to flexibly develop modern, connected rail vehicles. For example, the modular locomotive brake control unit CCB-3 presented at InnoTrans (Main Hall 1.2, booth 106) has been developed for all the important international rail transportation standards. For vehicle manufacturers intending to sell their locomotives in different markets, this reduces the vehicle redesign requirements. Knorr-Bremse subsidiary Selectron is also taking the connectivity concept further – here, with new CPU 94X vehicle control unit family (Hall 1.2, booth 106). The system is capable of handling up to three independent virtual control systems – for train control systems (TCMS), braking and diagnosis, for example – in a single vehicle control unit. Vehicle manufacturers and operators thus benefit from reduced integration, hardware and wiring requirements in the train, which both reduces costs and shortens delivery times.

Life-cycle efficiency
In the rail vehicle industry, the focus is not only on a vehicle’s purchase costs, but also on its life-cycle costs. Knorr-Bremse is acknowledging this with its main theme of “Life-cycle efficiency”: With modular and high-quality products and systems, optimized maintenance requirements and lasting obsolescence solutions, Knorr-Bremse is increasing vehicle availability and making vehicle operation more efficient. With the new EP2002 3.0 brake control unit, for example, the maintenance cycle has been extended from eight to at least ten years. Building on the success of its predecessor the EP2002, this new version, with which Knorr-Bremse has broadened the range of applications from metro to regional and long-distance transportation, includes extensive improvements. For example, thanks to its systems experience, Knorr-Bremse is able to use brake disc temperature monitoring to simulate brake disc temperatures in real time. In addition, the new deceleration control system delivers consistent braking distances regardless of the brake pad friction coefficient.

The new Knorr-Bremse control valve (KEf) (Main Hall 1.2, booth 106) is also to be seen in terms of life-cycle efficiency. Here, Knorr-Bremse has fundamentally redesigned its flagship control valve for the freight sector and is focusing on a common parts strategy: The KEf is so highly flexible that it meets the requirements of a wide range of vehicle types with just one distributor valve and only a handful of relay valve variants. It also simplifies the overhaul process significantly: The KEf replaces approximately 500 versions of the KE valve and their countless components.

Transport capacity
Urbanization calls for greater rail transportation capacities. Using compact design and new materials, Knorr-Bremse is developing solutions to increase passenger and freight transportation capacities while maintaining the same levels of functionality and consumption. The Light Weight Caliper with Safe-Park functionality exhibited at InnoTrans (Main Hall 1.2, booth 106) is a brake caliper for particularly weight-sensitive applications. In comparison with conventional calipers, its weight has been reduced by 33%, with the Safe-Park cylinder alone delivering a 43% weight reduction in comparison with standard spring brake cylinders. Also sanding systems such as the LRV Sanding System (Hall 1.2, booth 203) contribute to increasing rail transportation capacities. Speed-dependent sand dispensing offers operators sand consumption savings of up to 30% and shortens braking distances by up to 50%.

Ecodesign
Knorr-Bremse has its sights firmly set on the resource cycle. Ecodesign enables the company to reduce CO2 and noise emissions, for example, through its products and systems. In Hall 1.2 (booth 203), Knorr-Bremse subsidiary Kiepe Electric is presenting its groundbreaking IMC charging concept (In Motion Charging). This allows buses to operate in battery-powered mode on wireless route sections and be recharged when they are on sections with overhead lines. Kiepe Electric’s IMC500 is currently the most powerful in-motion charging system on the market. It enables efficient, resource-saving operation of large fleets on route networks which have no overhead lines on up to 80% of their network. The HVAC system demonstrator from Knorr-Bremse subsidiary Merak also belongs in the Ecodesign category: As an alternative to the refrigerant R134a, Merak uses the significantly more eco-friendly CO2 – and already achieves a performance level comparable with R134a under Central European operating conditions. For increased passenger comfort, Knorr-Bremse subsidiary IFE is launching a new sealing system for sliding doors. This features improved acoustic insulation which significantly reduces passengers’ exposure to noise. The system has been integrated into an entrance system in the Main Hall 1.2 (booth 106). As a key feature, a lifting mechanism has been integrated into the standard closing operation: This mechanism raises the door leaf shortly before locking, so that the top and bottom edges are sealed.

The Knorr-Bremse Group’s two main booths will be in the Main Hall 1.2 (booths 106 & 203). In order to present additional sub-systems in product-specific surroundings, Selectron will be showcasing its TCMS train control systems in Hall 6.2 (booth 212). Also the double booth shared by Microelettrica (control components and systems) and Knorr-Bremse PowerTech (energy supply systems) is located in Hall 17 (booths 206 & 208).
