Low-Cost Discrete Position Sensing For A Dual-Solenoid Transmission Actuator

摘要

An actuator is provided for preventing rotation of a rotary component including a plurality of teeth. The actuator includes a pawl pivotable about a first pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a first rotary direction. The pawl is biased toward an engaged position with the rotary component by a pawl spring. A solenoid includes an electrically activated solenoid and an armature movable from a first position for holding said pawl out of engagement with the rotary component to a second position for allowing the pawl to be engaged with the rotary component. The armature includes an armature stop that is engageable with an electrical contact of an electric circuit for sensing a position of the armature.
