CONTROL DEVICE OF AUTOMATIC TRANSMISSION

摘要

PURPOSE:To keep in the parking lock condition always even after drawing-off of an ignition key by forming from a solenoid to make such a control of a rotary bushing that it is rotated to allow downward motion of the position only during a certain while with a foot brake stamped. CONSTITUTION:A rotary bushing 25 is borne rotatably relative to a bolt 7 as shaft part and a nut 9. A disengaging lever 29 is supported so as to be movable vertically with respect to positioning plates 1, 1 and energized upward by No.2 return spring 31 at all times, and a boss 33 to rotate the rotary bushing 25 is pushed by depressing it to make it possible for a positioning pin 19 to move downward. A solenoid pin 39 of a solenoid 37 can be pushed outward by a spring fitted in the solenoid 37 and is coupled with the rotary bushing 25, which shall be put under such rotational control that the positioning pin 19 becomes movable downward for a certain while with a foot brake stamped.
