Knorr Bremse Systems For Commercial Vehicles India Private Limited

The air supply system includes compressors to generate the compressed air, and dryers, oil separators and condensate collectors to condition it. The end product is a specific volume of compressed air in the required quality.

Compressed air is an important source of energy for certain basic functions in a train. In addition to operating the brakes, it is required for opening doors, controlling the suspension, operating the sanding equipment - and also raising the pantograph or driving the windscreen wipers.

Air Supply System consists of following equipments:

• Compressors
• Air Dryers
• Condensate collectors
• Complete systems
  

Sanding systems:
Sanding systems are used in rail vehicles to improve friction between the wheel and the track. They can be operated automatically or by the driver to assist drive-off and braking.

In the case of emergency braking, the sanding system is triggered automatically. The sand is contained in a box and is distributed by compressed air between the wheel and the track. Knorr-Bremse supplies all the components for sanding systems:

• Air supply
• Sand metering
• Sand pipe heaters
• Sand level indicator
• Sand box lid

Advantages:

• low-maintenance
• favorable LCC values
• easily adaptable to different grain sizes
• compact design
• low-noise

Brake testing:
All rail authorities require a brake test to be carried out once a trainset has been put together. This includes a final, simplified test in conjunction with the locomotive. Another possibility is to use static testing equipment to test the trainset before it goes into service. This saves time and money and considerably increases the efficiency of modern make-up and marshalling yards.

Advantages:

• simple to operate
• extremely flexible
• special routines and high-performance components reduce filling time
• efficient, radio-controlled brake testing
• additional functions available such as leak testing of main reservoir, adjustment, rapid braking etc.
• field-proven components ensure high reliability and long life
• low-maintenance design
• favorable LCC values

The bogie equipment is the part of the overall system that actually generates the braking force. Thanks to our continuous product and systems innovation in this area we have been able to significantly improve braking performance, life-cycle costs, noise emissions and installation costs - while still upholding the very highest engineering and safety standards.

Each piece of bogie equipment is individually designed to take into account customer-specific operating conditions as well as fields of application and installation factors.

Bogie Equipment consists of following parts:

• Brake discs
• Brake pads
• Brake caliper units
• Block brake units
• UIC brake cylinders and slack adjusters
• Track brakes
  

The brake control system plays a crucial role in bringing a train to a safe halt, whatever the operating situation.

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:

• load-specific braking of loaded or empty cars
• anti-lock system (wheel slide control)
• driver alertness monitoring (SiFa)
• remote-controlled emergency braking (LZB, PenaltyBrake)
• passenger-operated emergency brake systems
• anti-wheel-skid systems

Irrespective of whether the train has a mechanical brake, electromagnetic track brake, eddy-current brake or reverse drive generator brake, the brake control system ensures optimum co-ordination of the various systems.

Main Components:

• Carrier system
• Control equipment
• Valves
• Brake controllers
• ESRA platform
• Electromechanics
• Sensors
• Electronic testing equipments
  

The decentralized EP2002 brake control system sets new standards for suburban trains and metro systems.

Combining mechanical and electronic elements in an extremely compact form, its local intelligence system offers both operators and manufacturers a number of advantages over traditional brake control systems. While maintaining the same safety standards, EP2002 is lighter, takes up less space and considerably reduces costs. Furthermore its decentralized design offers improved overall performance: by shifting the electronic control from a single, central unit to decentralized control modules located in each bogie, there is new scope for system parameterization and configuration. The largely modular design allows EP 2002 to be adapted to various vehicle systems.

Lightweight hydraulic systems that combine safety, flexibility and rapid response with high performance. The solution offered by Knorr-Bremse is a wide product range that has made a major contribution towards the development of new generations of vehicles such as low-floor tramways.

Hydraulic system consists of following parts:

• Hydraulic units
• Brake actuators
• Hydraulic suspension systems
• Shock absorbers
  

The Modular Brake Control System represents a further development and adaptation for the European market of the CCB II braking system that has already been so successful in the USA. Like the CCB II, the MBS system can be easily adapted to a wide range of different vehicles.

Its modular design makes for rapid and easy replacement of defective units. And an automatic self-diagnosis system helps avoid unnecessary maintenance work - reducing the amount of time MBS-equipped locomotives are out of service.

Each individual MBS module is equipped with its own computer that is linked to the others via a bus system. This makes it possible to limit the impact of localized faults and keep the overall system running longer. MBS also comes with a newly developed emergency brake control system that remains fully functional in pneumatic-only mode as well as electrical-only mode.
