Operator control device for an infinitely variable transmission

摘要

A control device for an infinitely variable transmission includes a control lever (16) that is movable along a guide slot (18) and whose position within the slot (18) indicates the commanded speed and direction. The control lever (16) is moved forward from a zero speed position (28) to a maximum forward speed position (32). Between the zero speed position (28) and maximum forward speed position (32) is a set point position (40) corresponding to a set point speed. A set speed adjuster (46, 48), such as a potentiometer, enables the operator to adjust the set point speed that is commanded when the control lever (16) is placed in the set point position (40). The speed for positions of the control lever (16) between the zero and the set point positions (28, 40) varies proportionally between zero and the set point speed. Likewise, the speed for positions of the control lever (16) between the set point position (40) and the maximum forward speed position (32) varies proportionally between the set point speed and the maximum forward speed.
