An electric booster control mechanism for an automobile clutch in the present invention is based on a mechanical clutch control mechanism, and is characterized in that the angular displacement of the clutch pedal is detected by the clutch pedal rotation angle sensor, and the working stroke of the clutch pedal is sensed, and the signal of the sensor is transmitted to The electronic controller controls the size and direction of the power boost of the power booster motor through the electronic controller, and transmits the force to the separation fork of the clutch through the driving swing arm on the power booster motor deceleration device. The invention can be applied to medium and light trucks and cars , Passenger cars and off-road vehicles that require high reliability, still maintain the driver's original driving habit of operating the clutch, which can reduce the driver's force to operate the clutch, and the operation is easy.

Description

An electric power-assisted control mechanism for automobile clutch

Technical field:

The invention relates to a control mechanism for an automobile clutch, which is based on a mechanical clutch control device with an electric power booster added.

Background technique:

Existing clutch control mechanism mainly contains three kinds of modes at present: 1 mechanical type; 2 hydraulic pressure type; 2 pneumatic assist type. Both mechanical and hydraulic control mechanisms use the driver's body as the only source of control energy. The mechanical control mechanism makes the driver's work intensity high. The hydraulic control mechanism is mainly composed of a master cylinder, a working cylinder, and a hydraulic system such as pipelines; although the hydraulic control mechanism has the advantages of convenient layout and soft engagement, the operation of the clutch still requires a large pedal force from the driver, and this The hydraulic system of the mechanism itself is prone to oil leakage, and its working reliability is not high. The pneumatic power-assisted control mechanism is easy to operate, but the air compressor driven by the engine is used as the main control energy source, so the structure is complicated. Pneumatic-assisted steering mechanisms are mainly used on heavy vehicles.

Invention content:

The purpose of the invention of an electric power-assisted operating mechanism for an automobile clutch is to provide an automobile clutch operating mechanism which is easy to operate. An electric booster control mechanism for an automobile clutch in the present invention is based on a mechanical clutch control mechanism, and is characterized in that the angular displacement of the clutch pedal is detected by the clutch pedal rotation angle sensor, and the working stroke of the clutch pedal is sensed, that is, the driver's manipulation is indirectly detected. The force of the clutch, the signal of the sensor is transmitted to the electronic controller, through the electronic controller to control the size and direction of the power boost of the power booster motor, and the force is transmitted to the separation fork of the clutch through the driving swing arm on the power booster motor deceleration device, increasing the power of the clutch The force of the separation fork to move the release bearing; the clutch pedal angle sensor is installed on the rotation fulcrum of the clutch pedal, and the clutch pedal angle sensor is connected to the electronic controller; the electric controller is connected to the booster motor, and the booster motor The rotation of the clutch is controlled by an electronic controller, and the driving swing arm on the reduction gear of the power assist motor contacts with the side of the lower end of the clutch release fork. In the present invention, a limit protection switch can also be installed at the critical point of the contact surface between the top of the drive swing arm and the separation fork, and the limit protection switch is connected to an electronic controller to control the maximum stroke of the drive swing arm. The invention can be applied to medium and light trucks, cars, passenger cars and off-road vehicles requiring high reliability, and still maintains the driver's original driving habit of manipulating the clutch, which can not only reduce the driver's force of manipulating the clutch, but also control the clutch. It is light, and when the booster system fails, the clutch can also be manipulated by manpower through the mechanical clutch control device, which improves the working reliability.
