Abstract

The invention relates to an electronic governor actuator, and belongs to the technical field of engine electronic governors. The electronic governor actuator comprises a connector. A pull rod baffle is arranged in the connector. The front end of the pull rod baffle is connected with a reset spring seat. The reset spring seat is connected with a reset spring. The pull rod baffle is connected with a pull rod on an oil pump through bolts. The pull rod penetrates through the reset spring seat, the reset spring, the connector and a connecting plate to be connected with the oil pump. A roller pin is fixed on the lower portion of a drive plate. The middle of the roller pin is located in the pull rod baffle, and the lower end of the roller pin is located in a displacement baffle. The side face of the connector is connected with a screw sleeve. A shutdown shaft is connected to the interior of the screw sleeve. The front end of the shutdown shaft is connected with a shutdown plate. The shutdown plate is located above the pull rod baffle and can make contact with the pull rod baffle under the action of the rotation of a shutdown handle. The electronic governor actuator is stable and reliable in use; the pull rod baffle and the reset spring are arranged, so that motion is stable, and quick and automatic resetting can be achieved; as the manual shutdown component is arranged, the safety of the actuator is improved; because a displacement sensor component is arranged, electronic governor actuator is higher in working accuracy and safer.

Description

technical field [0001] The invention relates to an actuator for an electronic governor, belonging to the technical field of electronic governors for engines. Background technique [0002] With the continuous stringent emission regulations and the continuous improvement of customers' requirements for diesel engine performance, traditional mechanical governors have been difficult to meet the requirements. However, due to high technical requirements, high price, and insufficient supply capacity, the high-pressure common rail system cannot immediately become the mainstream in the Chinese market, so the electronic speed controller has become another choice. According to the received relevant control parameter signals (speed, throttle position, etc.), the electronic governor realizes the change of the fuel supply of the fuel injection pump through the controller operation and the movement of the actuator, and controls the stable operation of the diesel engine. Compared with the m...
