BRAKEMATIC®
Controls for electrohydraulic brakes
Design and function
BRAKEMATIC® controls for electrohydraulic drum and disc brakes are consisting of a programmable frequency converter with function modules (software) and an input unit (pedal, internal or external parametrization interface, process control module with measuring sensor). A frequency change is generated at the output of frequency converter. This frequency change is used for activation of an ELDRO® thruster so that its hydraulic force can be varied. The resultant actuating force of ELDRO® is effective opposite to the braking force of braking system so that this relation forms the basis for the control of braking operation.
One BRAKEMATIC® control is sufficient for simultaneous operation of a number of brakes, provided the functions and the operation mode of brake systems are identical and the sum of the current input values of all ELDRO®'s is in conformity with the selected size of BRAKEMATIC®.

Note:
Working in conjunction with an electrohydraulic brake, the BRAKEMATIC® control forms one functional unit, i.e. both components are specifically adapted to each other. If one of the components is to be replaced, recalibration of the overall system is necessary.
