用于多模式离合器模块的力平衡曲拐致动器
摘要：
用于多模式离合器模块(8)的致动器(10)与曲拐(40)相互作用，以选择性地阻止棘爪(18)在该模块的内座圈(16)与外座圈(12)之间的相互作用。曲拐(40)围绕固定至外座圈(12)的销(42)枢转，从而通过固定至凸轮环(20)的转矩臂(52)将从致动器(10)延伸的柱塞(30)的直线运动转换成凸轮环(20)在两个角度极限之间的顺时针和逆时针运动。单件式曲拐(40)包括三个杠杆；第一杠杆(44)，与柱塞(30)相互作用；第二杠杆(46)，容纳狭槽(50)，该第二杠杆接合转矩臂(52)以控制棘爪移动；以及第三杠杆(54)，其具有大于第一杠杆(44)和第二杠杆(46)的质量以对曲拐(40)在外部引发的G力下产生的任何不受命令的旋转提供惯性阻力。因而，内座圈(16)和外座圈(12)在至少一个离合器操作模式下可更可靠地锁定在一起，并且在同一离合器操作模式中可自由滑行。
摘要（英）：

An actuator (10) for a multi-mode clutch module (8) interacts with a bellcrank (40) to selectively block interactions of pawls (18) between inner (16) and outer (12) races of the module. The bellcrank (40) pivots about a pin (42) fixed to the outer race (12), converting linear motion of a plunger (30) extending from the actuator (10) into clockwise and counterclockwise motions of a cam ring (20) between two angular limits by a torque arm (52) fixed to the cam ring (20). The one-piece bellcrank (40) includes three levers; one (44) interacting with the plunger (30), a second (46) containing a slot (50) to engage the torque arm (52) to control pawl movement, and a third (54) having a mass greater than the first (44) and second (46) levers for providing inertial resistance to any uncommanded rotation of the bellcrank (40) under externally induced G-forces. As such, the inner (16) and outer (12) races may be more reliably locked together in at least one clutch operating mode and can freewheel in the same clutch operating mode.
