Description

Technical Field

[0001] The utility model relates to the technical field of automotive clutches, and particularly relates to an air-electric dual-control clutch master cylinder. Background Art

[0002] The function of the clutch is crucial. It can enable the transmission system of the vehicle to achieve flexible separation or engagement, ensuring the smoothness and reliability of the vehicle during starting, shifting, etc. The application of the air-electric dual-control clutch master cylinder may further improve the performance and reliability of the clutch, providing a more comfortable and safe driving experience for the driver.

[0003] Most traditional clutches rely solely on mechanical structures to hydraulically transmit force and torque, with relatively slow response speed and sensitivity. Moreover, the pedal feel stroke and force adjustment of traditional clutches are usually relatively fixed and cannot be finely adjusted, making it difficult to adapt to different driving habits and driving conditions. At the same time, the quality of hydraulic oil varies, and the clutch master cylinder often leaks oil or admits air, resulting in a very hard pedal feel and even causing the master cylinder to fail. Summary of the Utility Model

[0004] The utility model mainly provides a clutch that can achieve the function of the clutch booster by air control when there is a problem with the electric control system.

[0005] To achieve the above object, the utility model adopts the following technical scheme: an air-electric dual-control clutch master cylinder, including a valve body. A stroke piston is connected to the inner top of the valve body. A magnetic ring is connected to the stroke piston. A valve rod is connected inside the stroke piston. A balance spring is connected between the bottom of the stroke piston and the valve rod. A return spring is connected between the stroke piston and the valve seat. The bottom of the valve body is connected to the valve seat. An air inlet hole is provided at the bottom of the valve seat. A valve is provided inside the valve seat.

[0006] Preferably, an exhaust hole is provided on the valve body. An electromagnetic sensor is connected to the outer surface of one side of the valve body. The electromagnetic sensor is electrically connected to a computer board. The computer board makes different instructions through different signals sent by the electromagnetic sensor and conducts them to the air-electric dual-control clutch booster, so as to quickly realize the required functions of the clutch operating mechanism.

[0007] Preferably, an air outlet hole is provided on the valve body. The air outlet hole is a key channel for gas to flow from the inner cavity of the clutch booster to the external pipeline. When the driver presses the clutch pedal, the valve rod is pushed to open the valve, allowing gas to enter the cavity through the air inlet hole.

[0008] Preferably, the electromagnetic sensor is connected to a computer board. The computer board can make different instructions through different signals sent by the electromagnetic sensor and give them to the air-electric dual-control clutch booster.

[0009] Preferably, an elastic structure is formed between the stroke piston and the valve rod by a balance spring. When the driver steps on the clutch pedal, the push rod presses against the stroke piston. As the stroke piston moves downward, the magnetic ring also moves downward with the stroke piston, and the electromagnetic sensor will also obtain the corresponding change in the magnetic ring signal.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are that

[0011] In the present utility model, the electro-control function of the air-electric dual-control clutch master cylinder is the main one. Because electro-control has a fast response speed, high sensitivity, the foot feeling stroke can be adjusted arbitrarily, the driver's operation comfort is high, and the force of stepping on the pedal is also light. The air-control system is auxiliary and standby. When the electro-control system has problems, the air-control can also realize the function of the clutch booster to ensure that the vehicle can drive safely and normally.

[0015] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0017] Please refer to Figure 1-2, the present utility model provides a technical solution: a gas-electric dual-control clutch master cylinder, including a valve body 1, a stroke piston 2 is connected to the inner top of the valve body 1, a magnetic ring 4 is connected to the stroke piston 2, a valve rod 5 is connected inside the stroke piston 2, a balance spring 3 is connected between the bottom of the stroke piston 2 and the valve rod 5, a return spring 6 is connected between the stroke piston 2 and the valve seat 13, the bottom of the valve body 1 is connected to the valve seat 13, there is an air inlet hole 9 at the bottom of the valve seat 13, and a valve 7 is inside the valve seat 13.

[0018] As Figure 1 and Figure 2 shown, an exhaust hole 8 is opened on the valve body 1, an electromagnetic sensor 10 is connected to the outer surface of one side of the valve body 1, the electromagnetic sensor circuit is connected to the computer board, and the computer board 12 issues different instructions through different signals sent by the electromagnetic sensor 10 and conducts them to the gas-electric dual-control clutch booster, so as to quickly realize the required functions of the clutch operating mechanism.

[0019] Preferably, an air outlet hole 11 is opened on the valve body 1. The air outlet hole is a key channel for gas to flow from the inner cavity of the clutch booster to the external pipeline. When the driver steps on the clutch pedal, the valve rod 5 is pushed to open the valve 7, allowing gas to enter the cavity through the air inlet hole 9.

[0020] As Figure 2 shown, the bottom of the electromagnetic sensor 10 is electrically connected to the computer board 12, and the computer board 12 can issue different instructions to the gas-electric dual-control clutch booster through different signals sent by the electromagnetic sensor 10.

[0021] As Figure 2 shown, an elastic structure is formed between the stroke piston 2 and the valve rod 5 by the balance spring 3. When the driver steps on the clutch pedal, the stroke piston 2 is pushed by the ejector rod. As the stroke piston 2 moves downward, at this time the magnetic ring 4 also moves downward with the stroke piston 2, and the electromagnetic sensor 10 will also obtain the corresponding change in the signal of the magnetic ring 4.

[0022] Usage method and working principle of this device: When the driver steps on the clutch pedal, the push rod presses against the stroke piston 2. As the stroke piston 2 moves downward, the magnetic ring 4 also moves downward with the stroke piston 2 at this time. The electromagnetic sensor 10 obtains the change of the signal of the corresponding magnetic ring 4, and the electromagnetic sensor 10 will also generate signal changes of different intensities. The computer board 12 makes different instructions based on the different signals sent by the electromagnetic sensor 10 to the pneumatic-electric dual-control clutch booster, so as to quickly realize the required functions of the clutch operating mechanism. At the same time, as the stroke piston 2 moves, it also pushes the balance spring 3 to apply pressure to the valve stem 5, and also pushes the valve stem 5 to push open the valve 7. The gas enters the cavity through the gap opened by the valve 7 through the air inlet hole 9, and then enters the air outlet hole 11 from the cavity. The pipeline connected to the pneumatic control port of the pneumatic-electric dual-control clutch booster through the air outlet hole 11 enters the pneumatic control port of the pneumatic-electric dual-control clutch booster, so as to realize the pneumatic control function of the pneumatic-electric dual-control clutch booster. The pneumatic-electric dual-control clutch master cylinder is mainly based on the electric control function, because the electric control has a fast response speed, high sensitivity, the foot feeling stroke can be adjusted arbitrarily, the driver's operation comfort is high, and the pedal force is also light. The pneumatic control system is auxiliary and standby. When the electric control system has problems, the pneumatic control can also realize the function of the clutch booster to ensure the safe and normal driving of the vehicle.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
