The brake system (10) includes a torque limiter assembly (48) that sets a torque limit and is associated with the electromechanical actuation system. The torque limiter assembly (48) includes a ring gear (62) engaged with the planetary gear set (70), the ring gear (62) including a first race (86) extending circumferentially thereabout. The torque limiter assembly (48) includes a preload member including a second race (88) extending circumferentially thereabout. A ball or roller (84) is engaged between the first and second races (86, 88). The first and/or second races (86, 88) include a series of peaks and valleys and ramps extending between the peaks and valleys. At or below the torque limit, the balls or rollers (84) engage within the valleys, causing the ring gear (62) to remain rotationally constrained and the planetary gear set (70) to be set to orbital operation. At and above torque limits, the balls or rollers (84) slip over a peak, causing the ring gear (62) to rotate and the planetary gear set (70) to remain orbitally constrained.

    制动系统(10)包括设定扭矩极限并且与机电致动系统关联的扭矩限制器组件(48)。扭矩限制器组件(48)包括与行星齿轮组(70)啮合的齿圈(62),齿圈(62)包括围绕其沿周向延伸的第一座圈(86)。扭矩限制器组件(48)包括预加载构件,预加载构件包括围绕其沿周向延伸的第二座圈(88)。球或滚子(84)接合在第一座圈和第二座圈(86,88)之间。第一座圈和/或第二座圈(86,88)包括一系列峰和谷以及在峰与谷之间延伸的斜面。在扭矩极限以下,球或滚子(84)接合在谷内,导致齿圈(62)保持旋转约束以及行星齿轮组(70)设定为轨道运行。在扭矩极限处及之上,球或滚子(84)滑过峰,导致齿圈(62)旋转以及行星齿轮组(70)保持轨道约束。
