CONTROL-PEDAL-MECHANICAL SPEED WITH ELECTRICAL DIRECTION CONTROL

摘要

A control linkage for combined simultaneous control of an engine throttle and a transmission ratio control includes a foot pedal mounted for physical movement about a first axis from its zero position, a throttle linkage connecting the pedal to an engine throttle for movement therewith through the control range and transmission ratio control linkage connecting the control pedal to a ratio control value for movement with the pedal through the control range and means for shifting the ratio control linkage to a first position for movement with the pedal and a forward for movement of the valve in a forward direction and shiftable to a second postion for movement if the valve in the reverse direction upon movement of the control pedal.
