To illustrate theEBS control processes the function model has two electrically driven wheelassemblies to simulate the trailer axle. The flexible connections of thecomponents ensure maximum freedom in the design of learning situations andaction-oriented transfer of knowledge. The coloured hoses support a clearstructured experimental setup. For connection of suitable diagnostic equipment,the facility has a WABCO Trailer diagnostic interface. Equipped with two largepressure gauges and original test terminals, the test steps in the function andpressure-resistance test can be done in accordance with Annex 29 to trafficregulations.
