Abstract

The purpose of the utility model, an electric power-assisted clutch for automobiles, is to provide an automobile clutch control mechanism with easy operation. The utility model is an electric power-assisted clutch used for automobiles, which is composed of a clutch pedal, a pull rod, a clutch release shift fork, a release bearing, etc., and is characterized in that the utility model also includes a clutch pedal rotation angle sensor, a booster motor and its speed reduction device, Electronic controller; the swinging action of the drive swing arm on the reduction gear acts on the release fork of the clutch, increasing the force of the clutch release fork to move the release bearing. The utility model still maintains the driver's original driving habit of manipulating the clutch, can reduce the force of the driver manipulating the clutch, and is easy to operate.

Description

An electric power-assisted clutch for automobiles

Technical field:

The utility model relates to an operating mechanism for an automobile clutch, which is based on a mechanical clutch operating device with an electric 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 utility model, an electric power-assisted clutch for automobiles, is to provide an automobile clutch control mechanism with easy operation. The utility model is an electric power-assisted clutch used for automobiles, which is composed of a clutch pedal, a pull rod, a clutch release shift fork, a release bearing, etc., and is characterized in that the utility model also includes a clutch pedal rotation angle sensor, a booster motor and its speed reduction device, Electronic controller, limit protection switch; the clutch pedal rotation angle sensor is installed on the rotation fulcrum of the clutch pedal, used to detect the angular displacement of the clutch pedal, that is, indirectly detect the active force of the driver's manipulation of the clutch, the clutch pedal rotation angle The sensor is connected to the electronic controller; the electric controller is connected to the booster motor. The rotation of the booster motor is controlled by the electronic controller. When the driver manipulates the clutch pedal, the clutch pedal angle sensor perceives the working stroke of the clutch pedal, and the signal from the sensor is transmitted to the electronic controller, which supplies current to the booster motor to control the magnitude and direction of the booster motor, and the power transmission of the booster motor For the deceleration device, the driving swing arm on the deceleration device swings to the release fork of the clutch, increasing the force of the clutch release fork to move the release bearing. A limit protection switch is installed at the critical point of the contact surface between the top of the driving 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 on the reduction gear. The utility model 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 force of the driver manipulating the clutch, It is easy to operate, 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.
