The invention provides an electromagnetic actuator for a wheel-end disconnect device. A wheel end disconnect system includes an inner race connected to one of an axle half shaft and a wheel hub, an outer race connected to the other of the axle half shaft and the wheel hub, and a plurality of radially actuatable pawls, circumferentially spaced apart, oriented between the inner and outer races, and movable between an outboard locked position and an inboard unlocked position to connect and disconnect the wheel hub from the axle half shaft. The system further includes a plurality of pins attached to an actuator ring. The actuator ring is axially shift-able between a locked and unlocked position. The system also includes one or more permanent magnets forming a permanent magnet ring attached to the actuator ring, with axially spaced apart north and south poles, and an annular tri-pole electromagnet having two counter-wound axially spaced apart coils concentric with the annular permanent magnet.

    本公开提供“用于车轮端部断开装置的电磁致动器”。一种车轮端部断开系统包括:内座圈,其连接到车桥半轴和车轮轮毂中的一者;外座圈,其连接到车桥半轴和车轮轮毂中的另一者;以及多个径向可致动的棘爪,其周向地间隔开,取向在内座圈和外座圈之间,并且可在外侧锁定位置和内侧解锁位置之间移动,以将车轮轮毂与车桥半轴连接和断开。系统还包括多个管脚,所述多个管脚附接到致动器环。致动器环可在锁定位置和解锁位置之间轴向地移位。系统还包括:一个或多个永磁体,其形成附接到致动器环的永磁体环,具有轴向地间隔开的北磁极和南磁极;以及环形三磁极电磁体,其具有与环形永磁体同心的两个反向缠绕的轴向地间隔开的线圈。
