摘要： An electromagnetic clutch assembly for transfer cases (16) and other motor vehicle powertrain applications includes a friction disc clutch pack (150) and an electromagnetic operator that applies compressive force to the clutch pack. The electromagnetic operator includes an electromagnetic coil, a rotor (170) partially surrounding the coil, an armature (174) and a ball ramp operator (152) assembly that provides compressive force when the coil is energized. The rotor and armature include aligned paths or tracks of arcuate slots (246) separated by webs or spokes (248) which create a sinuous magnetic flux path and improve performance. The number of slots and thus the number of spokes in the rotor and armature paths are unequal. This inequality greatly reduces pulsations caused by small fluctuations in clutch engagement associated with the repeated, simultaneous alignment and non-alignment of the spokes in a rotor and armature having equal numbers of spokes. This results in improved smoothness of operation and reduces noise and vibration.

摘要翻译： 用于转移箱（16）和其它机动车辆动力系应用的电磁离合器组件包括摩擦盘式离合器组件（150）和向离合器组件施加压缩力的电磁操作器。 电磁操作器包括电磁线圈，部分围绕线圈的转子（170），当线圈通电时提供压缩力的电枢（174）和滚珠斜坡操作器（152）组件。 转子和电枢包括由腹板或轮辐（248）分开的弓形槽（246）的对准的路径或轨道，其产生弯曲的磁通路径并提高性能。 因此，转子和电枢通道中的槽数以及轮辐的数量是不相等的。 这种不等式大大减少了由于转子和具有相等数量辐条的电枢的轮辐的重复同时对准和不对准而引起的离合器接合的小波动引起的脉动。 这导致操作的平滑性得到改善并且降低了噪音和振动。
