TRANSMISSION CONTROL INTERFACE MECHANISM |
摘要 |
A vehicle includes a hydraulically operated multi-speed transmission controlled by a rotary pilot valve and pilot-operated shift valves. An electronic control unit generates electrical control signals for automatically controlling the transmission. A manually movable lever generates mechanical transmission control signals. An interface mechanism includes a sector gear which rotates the rotary valve in response to movement of the lever. A stepping motor rotates the sector gear via a torque-multiplying gear train in response to the electrical control signals. A rotary gear ratio encoder is rotatably cooupled to the rotary pilot valve and generates signals indicative of the actual gear ratio of the transmission. |
