HYDRAULIC FORWARD/REVERSE SHIFT FORK CONTROL FOR A POWER TRANSMISSION

摘要

A shift fork for a forward-reverse shift mechanism has a hydraulic piston portion for moving the shift fork. The piston is controlled by a hydraulic valve system. The valve system is effective to delay the engagement of the respective forward and reverse, hydraulically-operated, torque transfer devices. The shift fork will enforce the establishment of the proper power path through a synchronizer prior to the engagement of the torque transfer control devices.
