摘要: A shift fork actuation system includes an actuator housing defining a piston cavity and assembly having three pistons with different surface areas responsive to fluid pressure establish positions of the within cavity. stopping mechanism, such as shoulder formed by at interface bores in cavity, interferes one prevent movement past mechanism. neutral position is established interference slot captures finger extension from rail act anti-rotation feature, ensuring that magnet embedded part sensor properly positioned.
