Knorr-Bremse Group is the world’s leading manufacturer of braking systems for rail, public service and commercial vehicles. For over 110 years the company has pioneered the development, production, marketing and servicing of state-of-the-art bus air braking systems. Knorr-Bremse is a supplier to all of the world’s leading commercial and public service vehicle manufacturers.
Knorr-Bremse product range includes
Compressed air is the main source of energy for all pneumatic braking systems, air suspension systems and clutches used in PSV vehicles. Powered by the vehicle´s engine, the compressor generates the necessary compressed air required.
Knorr-Bremse covers a wide range of compressor systems, including flange mounted with direct gear drive, or base mounted with belt drive, one or two cylinder compressors. They can also be supplied by Imperial Engineering with an optional energy-saving system (ESS). A more recent Knorr-Bremse innovation is a compressor with built-in clutch which, as well as delivering considerable savings in fuel costs, also reduces oil emission.
Imperial Engineering has been an Authorised Distributor for Knorr Bremse bus and coach parts for almost 25 years.
Valves enable precise control of the supply of compressed air to the braking and suspension systems on buses and coaches.
Knorr Bremse is a major global leader in the manufacture of components for the whole braking system, which are supplied by Imperial Engineering, including foot brake valves, hand brake valves, relay valves, brake pressure regulators and air suspension valves.
Pedal units with integrated clutch actuation systems are also part of Knorr-Bremse’s wide range of valves. These Plug-and-Play modules offer the customer significant technical as well as logistical advantages.
EBS Control Modules
Knorr-Bremse is a market leader in the development of active and passive driver assistance systems and its product range includes ABS (anti-lock braking systems) and EBS (electronic braking systems).
EBS control modules integrate the functions of braking control, ABS and ASR (traction control), into one electronic system. The advantages of electronic control over conventional pneumatic control are shorter response time and braking distance, resulting in increased road safety.
Spring Brakes (rear) and Brake Chambers (front) and Brake Discs
The brake actuator converts pneumatic energy into mechanical energy. This results in the friction material being pressed against the brake contact surfaces, causing the vehicle to slow down or stop.
During braking, or in the case of a change of load, the compressed air is directed via control valves and/or control modules to the brake actuators or suspension bellows, at pressures over 10 bar.
For buses and coaches, Knorr-Bremse’s modular brake cylinder concept is applicable to all uses, covering vehicles of different size and performance. Due to its modular design by Knorr-Bremse’s technical specialists, the number of individual braking components has been greatly reduced. This means that the customer’s outlay on replacement parts and maintenance is significantly reduced.
