Abstract
The present invention provides a dial knob pivotably mounted and a hydraulic device for operating an inhibitor switch of an automatic transmission by creating hydraulic pressure using rotational motion of the dial knob, in order to provide a shift operating device for an automatic transmission that makes it possible to reduce manufacturing cost by having a simple structure and facilitate setting a layout by reducing a space for motion of shift knob, and makes it easy for a driver to shift by turning the shift knob with a hand to reduce the driver's tiredness and improve commercial value.
Claims7
A shift operating device for an automatic transmission having an inhibitor switch, comprising:
- a pivotably mounted dial knob;
- and
- a hydraulic device that operates the inhibitor switch of the automatic transmission by converting creating hydraulic pressure from rotational motion of the dial knob;
- wherein the hydraulic device includes a first hydraulic cylinder having a piston rod connected to the inhibitor switch, a second hydraulic cylinder having a piston rod connected to the dial knob, and a hydraulic line connecting the first and second hydraulic cylinder to transmit hydraulic pressure of the second hydraulic cylinder to the first hydraulic cylinder.
