ABSTRACT:
A governor system for limiting the ground speed of a vehicle and maintaining an idle speed of the engine. The governor system includes a first feedback shaft operably coupled with a transmission of the vehicle to provide a first feedback torque in response to a ground speed of the vehicle. A second feedback shaft is operably coupled with the engine to provide a second feedback torque in response to a revolutionary speed (RPM) of the engine. A ground speed governor system is coupled between the first feedback shaft and the throttle system of the engine for limiting operation of the throttle system in response to the first feedback torque, thereby limiting ground speed. An idle speed governor system is coupled between the second feedback shaft and the throttle system of the engine for actuating the throttle system in response to the second feedback torque, thereby maintaining a desired idle speed.
