What is the function of the clutch? The function of the motor vehicle clutch is mainly to separate and combine the power transmission between the power transmission of the engine and the output of the gearbox. That is to say, the power of the engine is transmitted to the output of the gearbox, and a clutch is installed in the middle. When the clutch is engaged, the power of the engine is transmitted to the gearbox, and when the clutch is disengaged, the power transmission to the gearbox is cut off. Cut off and maintain power transmission.
Although we all know that a clutch is installed on a motor vehicle, whether it is a manual transmission model or an automatic transmission model, there is a clutch device. Because the power of the vehicle is provided by the engine, and the engine provides power by relying on the combustion of the engine to do work, and then the power is transmitted to the gearbox, which matches the appropriate power and then transmits it to the wheels. The rotation of the wheels drives the wheels forward.
The idle speed of the engine in normal operation is 800~1000 rpm, and the speed will increase when the power is output. This speed cannot be directly transmitted to the vehicle to drive the wheels to rotate forward, which is matched by the gearbox. Different power outputs, after adjusting to the appropriate power, are transmitted to the wheels to drive the wheels forward. The clutch is located between the engine and the transmission, and is used to disconnect and combine the transmission of power, enabling the vehicle to start, stop, and change gears.
Let's look at the specific working principle of the clutch. In simple terms, a driving disc is connected to the engine, a driven disc is connected to the gearbox, and then the clutch plate is in the middle. Through the gradual combination of the clutch plate and the driving disc, the rotation of the driven disc is driven, and after the final combination, the driving disc and the driven disc keep rotating synchronously to realize the transmission of engine power. The clutch pedal is operated by the manual transmission. When we step on the clutch pedal, the clutch plate and the active plate are separated. At this time, the driven plate and the active plate are also separated, and the engine power is cut off. We can switch to the appropriate gear, and then release the clutch pedal, the clutch combined with the driving disc drives the driven disc to rotate, the power is transmitted to the gearbox, and finally the wheels turn the vehicle to move forward.
The automatic transmission also has a clutch, but the clutch is electronically controlled by a trip computer, which can be separated in time, and combined more quickly, and automatically switch to the appropriate gear to maintain the continuous output and transmission of power, and the vehicle moves forward. . In addition, explain the dual clutch gearbox. The same principle is only equipped with two sets of clutch systems. When one clutch system is working, the other clutch system is ready to work. After switching the gears, it can be directly combined into the working state, reducing the It eliminates the loss of power and the interruption of transmission in the separated state.
Since the clutch controls the separation and combination of power output, this is why the driving of manual transmission models requires better oil separation and coordination to achieve smooth driving of the vehicle and improve the fuel economy of the vehicle. In the process of gear switching, the power transmission of the engine is completely disconnected by the separation of the clutch. After the gear switching is completed and the clutch is engaged, the transmission and output of the engine power will continue.
Based on the above description of the clutch structure and working principle, the function of the clutch is mainly to interrupt and maintain the power transmission of the solid-line vehicle engine through the combination and separation of the clutch. Therefore, the variable transmission of vehicle power can be realized, the smooth start of the vehicle, the shift of gears, and the smooth transition in the process of power transmission can be realized.
Of course, the structure and working principle of the clutch are just a simple example. The specific clutch structure is relatively complex, and there are multiple components involved in the separation process. With the advancement of automobile manufacturing technology, clutches of different types and materials are also put into use, which can realize more clutch functions. However, the main function of the clutch has not changed, it is still to control the cut off and hold during the power transmission process.
