Abstract
A brake system comprising a torque limiter assembly that sets a torque limit and associated with an electromechanical actuation system. The torque limiter assembly comprises a ring gear meshed with two or more planetary gears, the ring gear comprising a first race extending circumferentially therearound. The torque limiter assembly comprises a pre-loaded member comprising a second race extending circumferentially therearound. Balls are engaged between the first and second races. The first and/or second races comprise a series of peaks and valleys, and slopes extending therebetween. Below the torque limit, the balls are engaged within the valleys causing the ring gear to remain rotationally captive and the planetary gears to orbit. At and above the torque limit, the balls slip over the peaks, causing the ring gear to rotate and the planetary gears to remain orbitally captive.
