摘要： A park lock of a transmission, including a park gear; a park pawl rotating about a pawl shaft, the park pawl having a pawl portion locking the park gear, the park pawl including a cam contact portion; a park rod responsive to an operation of a controller, the park rod having a cam portion pressing the cam contact portion to have park pawl engage the park gear; a park sleeve receiving the cam portion and defining a first contact point providing a reactive force to the cam contact portion of the park pawl pressing against the cam portion at a second contact point; a pawl torsional spring biasing the park pawl towards disengagement; and a pawl stopper limiting the rotation of the park pawl wherein motions are constrained within a plane of the transmission and components are rotatingly disposed in parallel axis bores in one half of a transmission case.
