how does a clutch work


The concept of the clutch is an important part of the automobile power system. It is responsible for cutting off and connecting the power supply and the engine. In the steel sheet pile manufacturing process, the clutch is used to connect the plate shape of other suppliers, and it has become one of the most commonly used components. How to use the clutch correctly, master the principle of the clutch and use the clutch to solve the problem under special circumstances, Jiangsu Shunli Steel Group has the following introduction:


What is the working principle of clutch?

What working status can clutch be divided into?

The working process of a typical clutch is introduced in detail.


What is the working principle of clutch?

As the name implies, the so-called clutch means the use of "open" and "close" to deliver appropriate power. The clutch consists of friction plate, spring plate, pressure plate and power output shaft. It is located between the engine and the gearbox.


In steel pipe manufacturing, clutches are often used to link pipe piles. As an accessory to the pipe piles, they play an important role in linking and matching two kinds of pipe piles. The thickness of the sheet pile should be considered when selecting the thickness of the clutch. Generally, we recommend that the thickness of the stripper should be the same as the thickness of the sheet pile so that they can match each other perfectly.


What working status can clutch be divided into?

The clutch is divided into three working states, namely, the non-interlocking when the clutch is depressed, the full interlocking when the clutch is not depressed, and the semi-interlocking when the clutch is partially depressed. When the vehicle starts, the driver steps on the clutch, and the movement of the clutch pedal pulls the pressure plate back, that is, the pressure plate is separated from the friction plate. At this time, the pressure plate and the flywheel are completely out of contact, and there is no relative friction.


When the vehicle is running normally, the pressure plate is tightly squeezed against the friction plate of the flywheel. At this time, the friction between the pressure plate and the friction plate is the largest, and the relative static friction between the input shaft and the output shaft is maintained, and the speed of the two is the same. .


The last one is the semi-interlocked state of the clutch, where the friction between the pressure plate and the friction plate is less than the fully interlocked state. At this time, the clutch pressure plate and the friction plate on the flywheel are in a state of sliding friction. The speed of the flywheel is greater than that of the output shaft, and the power transmitted from the flywheel is partly transmitted to the gearbox. In this state, the engine and the driving wheels are equivalent to a soft connection state.


The working process of a typical clutch is introduced in detail.

Diaphragm spring clutch, its work can be divided into three processes: work, separation and engagement.

1. work process. When a diaphragm spring is used to install between the clutch cover and the pressure plate, the pressure on the pressure plate formed by the pre-compression deformation makes the main part and the driven part of the clutch compact, that is, the clutch is in an engaged state. Engine power is transmitted to the driven plate through the flywheel, clutch cover and pressure plate integrated with the crankshaft, and then to the input shaft of the transmission through the driven plate spline sleeve. The working characteristic of this process is that the main part of the clutch and the driven part transmit the same torque and speed, and there is no difference in speed between the main part and the driven part, and there is no slip.


l 2. Separation process. The driver steps on the clutch pedal, the pedal moves to the left, the push rod moves to the left, and the diaphragm spring release plate moves to the left through the air cylinder and the working air cylinder. Affected by this, the diaphragm spring uses the support pin fixed on the clutch cover as a fulcrum to make the big end move to the right. At the same time, under the action of the partition plate, pull the pressure plate to move to the right. Finally, there is a gap between the driven plate, flywheel and pressure plate, the clutch is separated, and the clutch separation process ends. The working characteristic of the clutch during the separation process is that the power and movement of the engine cannot be realized. After separation, it is transferred to the driven board. The movable part is still synchronized with the engine speed, while the driven part decreases rapidly.


l 3. Joining process. The movement of the operating mechanism during the joining process is the opposite of the separation process. When a reserved gap appears between the release bearing and the diaphragm spring release plate, and the diaphragm spring re-presses the pressure plate on the driven plate, the engagement process ends and the clutch resumes its power transmission function.
