PARKING LOCK APPARATUS FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE: A parking lock device for an automatic transmission is provided to prevent malfunction by connecting a piston to a piston rod with a pin. CONSTITUTION: An accumulator(110) has a port for inputting and outputting fluid. A piston(120) is movably installed inside the accumulator. A piston rod is protruded to the outside of the accumulator and is connected to a lock device of a transmission driver. A piston rod(130) is connected to a piston by passing through the end of the accumulator. The cylinder is combined with the cylinder. A solenoid valve(160) restricts the movement of the piston by fixing the cylinder when power is applied.
