    摘要: An electrically actuated aircraft brake system and method which provides for brake wear measurement, brake running clearance adjustment, ram position-based control and improved construction and operation. Brake wear and running clearance measurement are obtained by analyzing the output of position sensing circuitry. The position sensing circuitry, preferably including a LVDT position sensor, is also used to determine braking load, a brake controller including circuitry for effecting displacement of one or more reciprocating rams to load a brake disk stack by a predetermined amount based on a present displacement value of the position signal obtained from the position sensor. The position sensor preferably includes a LVDT transducer connected between the reciprocating ram and a brake housing, and the motive device preferably includes a servo motor. Also provided is an actuator housing including a guideway for each ram, the guideway and ram having the same polygonal cross-section, whereby the ram nut is guided and restrained from rotation by the guideway as it is translated by a ball screw in threaded engagement with the ram nut for selective movement into and out of forceful engagement with the brake disk stack for applying and releasing braking force on a rotatable wheel. An electric motor is drivingly connected to each ball screw by a first gear integral with the ball screw, a second gear in mesh with the first gear, and a pinion on a rotating drive shaft of the electric motor.
