ABSTRACT:
This invention provides brake clamping and declamping in response to a position feedback controlled brake actuator in which an electric torque motor drives a rotating member of a reciprocating drive mechanism to axially move another member into out of engagement with a brake pressure plate of a multi-disk brake assembly. A microprocessor controller receives electric signals indicative of (i) a pilot's command for braking, (ii) a command for brake release and antiskid braking, (iii) the position of the torque motor rotor at any instant, and (iv) the initiation of brake clamping of the multi-disk brake. The controller generates a feedback control signal to the torque motor which adjusts the motor rotor position, in revolutions, to increase or decrease brake clamping in accordance with the pilot signal and to effect brake release in accordance with an overriding antiskid signal.
