It is easy for delays to occur while passengers are getting on and off the train. The quality of the access system, therefore, has an important influence over the operating efficiency of rail vehicles. Calculations show that the advantage to a business of a high quality access system exceeds its procurement costs by up to ten times. The security and the comfort of the passengers are always in focus when developing a detection systems and access devices.

Knorr Bremse Servo Shift module
The Knorr-Bremse Servo-Shift module is a pneumatically operated, servo-assisted shift system for manual transmissions. Thanks to the reduced shifting forces, the system allows a quick and comfortable gear change for maximum road safety and supports the driver in selecting the correct gear for the optimum fuel consumption. A combined servo force and shift speed limitation also protects the synchronization units of the gearbox. The Servo-Shift module can be adapted quickly and easily to suit various gearbox types. The application of the module can be realised via gear linkage or bowden cable system.

Knorr-Bremse Drum Brake
Knorr-Bremse develops, manufactures and markets S-Cam drum brakes and slack adjusters. Together with pneumatic brake actuators and brake drums they represent a foundation brake system. Knorr-Bremse Drum Brake Function of the product With all types of drum brakes, friction forces are generated by internal brake shoes being pressed against the inner surfaces of the brake drum by the force generated by a cam. Due to their almost completely sealed housing, the brake shoes are well protected against corrosive influences (water, salt, dust) and dirt (sand, stones and mud), even when driving on rough

brake pad back plate
ProTecS® The connection between the brake pad back plate and spring holder ensures precise utilisation of the spring’s elasticity and thereby optimal alignment of the brake pads. The construction of the spring system increases the life expectancy of the brake pads, especially on rough roads. In addition, the welded spring holder acts as a slider resulting in protection of the spring and pad retainer, thereby reducing wear and tear. Due to the reduced friction between the spring holder and pad retainer, the ProTecS® pads return from their contact with the disc more easily. An additional improvement, combined with the introduction of the ProTecS® system, is the cast back plate. The lighter weight of the plate reduces the inertia of the brake pad, resulting in a reduction in noise development. An additional benefit is a reduction in the deformation of the brake pad in contact

Hydraulics
Passengers today expect a lot from modern local public transport vehicles. They demand a high degree of freedom of movement, comfort and safety. As a result, the amount of space available for installing braking systems is becoming increasingly limited. Hydraulic brake caliper The challenge today is, therefore, to design extremely compact, light hydraulic systems, which combine safety, flexibility and fast response characteristic with high performance. As a solution to this, Knorr-Bremse offers a wide product range which has contributed decisively to the development of new vehicle generations such as, for example, the low floor tramway.

Hydraulic Dampers
Hydraulic Damper
The HYDROLASTIC damper reduces rotary oscillation in accordance with the hydrodynamic extrusion principle. Rotary oscillation causes a relative motion in the damper between the primary mass (hub) and secondary mass (housing). As a consequence of this relative motion, mineral oil is pressed through a narrow slot. The resulting drop in pressure equates to a hydraulic drop in power, which has a damping effect.

Hand Brake Valve
EP Compact
Brake control is an extremely safety-relevant sub-system of the train due to the fact that it must allow reliable stopping of the train in all operating conditions. EP Compact Optimum braking is achieved if operation of a single lever by the driver results in an individual braking force being applied to each axle or bogie of the train. As the driver himself is not in a position to apply the brakes with a specific force to each axle or bogie, modern brake control systems need to have a large number of integrated intelligent functions:

Engine Air Exhaust Brake
Exhaust Brake Exhaust Brakes are used on diesel engines to provide vehicle retardation by choking the exhaust gas flow downstream of the turbocharger. The exhaust brake has a throttle valve which is actuated by a pneumatic operating cylinder. The back pressure realized by a conventional uncontrolled exhaust brake is proportional to the engine speed. The controlled exhaust brake however is equipped with a mechanism that maintains a constant counter-pressure downstream of the turbocharger in a defined gas flow range. This consequently allows constant retardation that is independent of engine load and speed.

electronic systems
t is estimated that, in the European Community, the equipping of all trucks and busescoaches with electronic systems would result in 500 fewer deaths and 2,500 fewer injuries due to road accidents per year. Knorr-Bremse is pressing ahead with the development of active and passive driver assistance systems and is thereby making a significant contribution to increasing safety on the roads. The product program in the area of electronic systems ranges from legally required ABS (anti-lock braking systems), through EBS (electronic braking systems) to ESP (electronic stability program) and ACC (adaptive cruise control). ABS, ASR ABS prevents locking of the wheels when braking, while ASR (traction control system TCS) ensures that, when accelerating, the wheels on the drive axle do not spin, thereby ensuring optimal traction in all driving conditions. As a pioneer in the development of ABS systems for commercial vehicles, Knorr-Bremse provides ABS and ASR systems for all vehicles types and trailers with air braking.

Electronic Gear Control Unit for Automated Manual Transmission (AMT)
An electronic gear control unit allows a fully automatic gear change to be made with a manual gearbox; the unit is usually directly mounted on top of the gearbox. The electronic gear control unit is a combination of mechanical components (e.g. pneumatic cylinders) as well as electrical components (e.g. solenoid valves, cables, electronic control units). Due to the integration of several functions, today�s automated manual transmission (AMT) modules reach an enormous degree of complexity. An AMT is the basis for the improvement of the driving comfort and the reduction of the load of the driver. The driver is able to focus his attention on the road traffic; there is no need to concentrate on the gear selection and gear shift process any more. The use of an optimized gear shift strategy (selected by the system and based on the driving situation), means that AMT can significantly reduce fuel consumption and mechanical wear in e.g. tractortrailer couplings when compared with conventional manual gear box operation.
