WABCO EBS construction kit The design and structure of WABCO EBS allow high flexibility for vehicle manufacturers during system construction. In terms of range electrical interfaces the most complex demands can, therefore, be met. To meet the vital needs of the vehicle owner, WABCO recommends an EBS with an individual pressure control unit on the front and rear axle, and which provides for pneumatic redundancies in all brake circuits.
subsystem or full system addition and cut-off redundancy supply third axle Battery halt brake 2P/1E-EBS AME = Axle modulator BWG = Brake signal transmitter ECAS = Electronically Air Suspension System EMR = Electronically engine control PRV = Proportional relay valve REDV = 3/2 relay valve (redundancy valve) RET = Retarder RV = Relay valve S = Speed sensor V = Wear indicator The EBS described here consists of a dual-circuit, purely pneumatic unit and a superimposed single-circuit, electro-pneumatic unit. This configuration is described as 2P/1E system. desired value sensors and brake switches, as well as a proportional relay valve and two ABS valves for the front axle.
The single-circuit, electro-pneumatic unit comprises a central electronic control device (central module), the axle modulator with integrated electronic unit for the rear axle, and, if necessary, the axle modulator for the third axle, a brake signal transmitter with two integrated In terms of structure, the dual-circuit pneumatic unit basically corresponds to that of a conventional braking system. This unit serves as redundancy and only becomes active in case of electro-pneumatic circuit failure. System structure in buses EBS 2. 5
