Abstract
PURPOSE: To meet displacement of tilt angle with running condition and to make operation of transmission accurate and easy by controlling tilt angle of motor swash plate through servo motor having controlling valve and operation cam.
CONSTITUTION: Difference of displacement between proportioning control force of opening of throttle valve and number of revolution of engine in main servo motor MS having controlling valve is converted into displacement. The displacement is transmitted to Change servi motor CHS through operation cam 131 by amplyfying the displacement. Thus, automatic control can be done accurately by meeting tilt angle of swash plate 11 with running condition of engine. Also transmission operation can easily and accurately be made as it is controlled hyperbolically by meeting with the relation of change gear ratio i, torque ratio T between input shaft 3 and output shaft 15, and displacement of tilt angle between Low-Top of motor swash plate 11 through cam surface e3 of operation cam 131.
