What is the structure and working principle of the clutch?

Clutch. structure and working principle.

1) Clutch structure.

Friction clutch is the most widely used clutch, and its structure is usually composed of four parts: the active part, the driven part, the pressing mechanism and the control mechanism.

1-crankshaft. 2-driven shaft; 3-driven disk; 4 — fly.

The composition and role of each part are shown in the table.

<> types of friction clutches, there are two types of clutches, diaphragm spring type and multi-reed clutch in the form of pressing and compressing springs, as shown in Figure 2-4. Among them, the diaphragm spring of the diaphragm spring clutch has two functions: compressing and disengaging the lever.

2) The working principle of the clutch.

It is usually divided into clutch engagement state and clutch release state.

3) The structure of a typical clutch.

At present, diaphragm spring clutches are widely used in cars. Among them, the diaphragm spring is used as the hold-down mechanism, which can be divided into two types: push type and pull type according to the different force of the diaphragm spring by the separation lever.

Push diaphragm spring clutches are widely used in various light vehicles.

When the driven disc is subjected to torque, the torque is transmitted from the friction lining to the driven disc steel plate, and then transmitted to the driven disc hub through the damping spring, at this time, the spring will be compressed to absorb the torsional vibration from the engine.

The hold-down mechanism is a diaphragm spring, which has a number of grooves in the radial direction to form an elastic lever. There are round holes at the end of the grooving, through which the fixing rivets are passed and fixed to the clutch cover. The two sides of the diaphragm spring are equipped with steel wire support rings, and these two steel wire support rings are the fulcrum of the diaphragm spring when working.

The outer edge of the diaphragm spring is connected to the pressure plate by a separating hook.

Extended Information: Construction of Diaphragm Spring Clutch:

The outer circumference of the driven disc steel sheet is riveted with a wavy spring steel sheet, the friction lining is riveted on the spring steel sheet respectively, and the driven disc steel sheet is riveted together with the shock absorber plate, and there is a friction washer and a driven disc hub sandwiched between the two. The driven disc hub, the driven disc steel plate and the shock absorber disc all have six window holes evenly distributed around the circumference, and the vibration damping spring is installed in the window hole.

The separation mechanism of the diaphragm spring clutch is mainly composed of a release fork, a release bearing and a release bearing seat. When stepping on the clutch pedal, the clutch control mechanism transmits the force to the separating fork, and the separating fork plays a lever role, and the fulcrum of this "lever" is the supporting point of the separating fork, and the separating fork pushes the disengaging bearing seat to press the discharging bearing to the diaphragm spring, so that the clutch is disengaged. The retaining ring of the separating bearing serves as a connection between the separating housing and the separating fork.

It transmits engine power to the gearbox and allows transmission to be interrupted when choosing to move out of a gear from a stationary position, or when shifting gears while the car is moving.

<> friction clutches used in most cars are either operated by a fluid (hydraulic) or, more commonly, by a cable.

When the car is driven under power, the clutch engages. The pressure plate, which is bolted to the flywheel, exerts a constant force on the driven disc by means of a diaphragm spring.

Earlier cars had a series of coil springs at the back of the pressure plate, rather than diaphragm springs.

The driven (or friction) disc runs on a splined input shaft, and the power is transmitted to the gearbox via the spline. The brake disc has friction linings on both sides, similar to brake linings. This allows for smooth actuation when the clutch is engaged.

When the clutch disengages (pedal is pressed), one arm pushes the release bearing to the center of the diaphragm spring, releasing the clamping pressure.

The outside of the pressure disc has a large friction surface, so the driven disc is no longer clamped to the flywheel, so the power transmission is interrupted and the gears can be changed.

Hydraulic clutch system.

<> clutch engagement.

<> clutch disengagement.

<> when the clutch pedal is released, the thrust bearing is retracted and the diaphragm spring load clamps the disc to the flywheel again to restore power transmission.

Some cars have hydraulic clutches. The pressure on the clutch pedal in the car actuates the piston in the master cylinder, which transmits the pressure through a filling tube to the slave cylinder mounted on the clutch housing.

The driven cylinder piston is connected to the clutch release arm.

Clutch components.

Modern clutches have four main components: a cover plate (including diaphragm springs), a pressure plate, a driven disc and a release bearing.

The cover plate is bolted to the flywheel, and the pressure plate applies pressure to the driven disc by means of diaphragm springs or coil springs on early automobiles.

The driven disc runs on a splined shaft between the platen and the flywheel.

It has a friction material on each side that clamps the pressure plate and flywheel when fully engaged, and when the clutch pedal is partially pressed, the friction material slides in a controlled amount, allowing the drive to proceed smoothly.

1. Through this clutch plate, the engine and the transmission system are friction to transmit power, when the clutch is stepped on, the clutch plate will be separated from the high-speed flywheel behind the engine, so that the clutch plate is not affected by the power of the engine, and the tooth in the middle of the clutch plate is used to connect the gearbox transmission system.

2. When the clutch is slowly released, the clutch plate will slowly approach the high-speed flywheel, and the clutch plate will be affected by the rotation of the flywheel itself, and at the same time, because of its own rotation, its power is directly transmitted to the car, and in the state of semi-clutch, there is friction between the clutch plate and the flywheel, which is very important, and the power transmitted in the friction is not large, so the car can start slowly and steadily.

3. When the clutch is completely released, the clutch plate and the engine flywheel are tightly adhered to, and no longer rubbing, but rotating with the rotation of the flywheel.

Clutch structure: Friction clutch is the most widely used clutch, and its structure is usually composed of four parts: the active part, the driven part, the pressing mechanism and the control mechanism.

The working principle of the clutch is usually divided into the clutch engagement state and the clutch disengagement state. The flywheel is fixed to the crankshaft, the pressure plate is fixed to the flywheel, and the clutch plate is clamped in the middle. Normal.

The structure of a typical clutch At present, diaphragm spring clutches are widely used in cars. Diaphragm springs are used as the hold-down mechanism.

The working principle of the combiner, this should be able to conduct a better command, so this should be able to be used better, this should be slowly released, he should be able to provide some power better.

The working principle of the clutch is to use "off" and "off" to transmit the right amount of power. The engine is always spinning, while the wheels are not. For a vehicle to stop without damaging the engine, the wheels need to be disconnected from the engine in some way.

The clutch controls the slip between the engine and the transmission, making it easy to connect a rotating engine to a transmission that is not spinning.

The main functions of the clutch are as follows:

1. Ensure a smooth start of the car.

After the engine starts, before the car starts, the driver first presses the clutch pedal, disengages the clutch, disengages the engine and the drive train, and then puts the transmission into gear, and then gradually releases the clutch pedal to make the clutch gradually engaged. In the process of engagement, the drag torque of the engine gradually increases, so the accelerator pedal should be gradually pressed at the same time, that is, the fuel supply to the engine should be gradually increased, so that the speed of the engine is always maintained at the lowest stable speed without stalling. At the same time, as the engagement of the clutch gradually increases, the torque transmitted by the engine to the driving wheels through the drive train gradually increases, and when the traction force is sufficient to overcome the starting resistance, the car starts to move from a standstill and accelerates gradually.

2. Achieve smooth gear shifting.

In the process of driving, in order to adapt to the changing driving conditions, the drive train often has to change different gears to work. To realize the gear shift of the gear transmission, it is generally to toggle the gear or other gear mechanism, so that a gear pair of the original gear is pushed out of the transmission, and then the gear pair of another gear is put into the work. The clutch pedal must be stepped on before the shift is lost, and the power transmission is interrupted, so that the meshing pair of the original gear can be disengaged, and the speed of the meshing part of the new gear meshing pair is gradually synchronized, so that the impact when entering the engagement can be greatly reduced, so as to achieve smooth gear shifting.

3. Prevent overload of the drive train.

When the car is braking urgently, if there is no clutch, the engine will be rigidly connected with the drive train and reduce the speed sharply, so all the moving parts will produce a large moment of inertia (its value may greatly exceed the maximum torque emitted when the normal pin shed of the mammoth machine is started), causing the load that exceeds its bearing capacity to the drive train, and the parts are damaged. With a clutch, this danger can be eliminated by relying on the relative movement that may occur between the active and driven parts of the clutch. Therefore, we need a clutch to limit the maximum torque that the drivetrain can experience in order to be safe.

According to the specific problem type, the steps are disassembled, the cause is analyzed, the content is expanded, etc.

The specific steps are as follows: The main reason for this is ......

The clutch structure and working principle are as follows: 1. The clutch is composed of friction plates, spring plates, pressure plates and power take-off shafts, which are located between the engine and the gearbox, and are used to transmit the torque stored on the engine flywheel to the gearbox, so as to ensure that the vehicle transmits the appropriate amount of driving force and torque to the driving wheels under different driving conditions, which belongs to the category of powertrain. 2. In the case of semi-linkage, the power input end and the power output end of the clutch are allowed to have a speed difference, that is, the appropriate amount of power can be transmitted through its speed difference.

3. In the various accessories of the clutch, the strength of the pressure plate spring, the friction coefficient of the friction plate, the diameter of the clutch, the position of the friction plate and the number of clutches are the key factors that determine the performance of the clutch.

The clutch is composed of friction plates, spring plates, pressure plates and power take-off shafts, which are located between the engine and the gearbox, and are used to transmit the torque stored on the engine flywheel to the gearbox, so as to ensure that the vehicle transmits the right amount of driving force and torque to the driving wheels under different driving conditions!

How it works. 1. The engine and the transmission system are transmitted by friction through the clutch, and when the clutch is stepped on, the clutch plate will be separated from the flywheel rotating behind the engine, so that the clutch plate is not affected by the power of the engine!

2. When the clutch is released, the clutch plate will slowly approach the high-speed flywheel, and the clutch plate will be affected by the rotation of the flywheel, and at the same time, because of its own rotation, its power is directly transmitted to the car, and in the state of semi-clutch, there is friction between the clutch plate and the flywheel, which is very important, and the power transmitted in the friction is not large, so the car can start slowly and steadily.

3. When the clutch is completely released, the clutch plate and the engine flywheel are tightly fitted, and no longer rubbing, but rotating with the rotation of the flywheel.

The automobile clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. While the car is moving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine from the gearbox to cut off or transmit the power input from the engine to the transmission.

The active part and the driven part of the clutch are used by the friction between the contact surfaces, or the liquid is used as the transmission medium (fluid coupling), or the magnetic transmission (electromagnetic clutch) is used to transmit torque, so that the two can be temporarily separated, and can be gradually engaged, and the two parts are allowed to rotate each other during the transmission process.

At present, friction clutches (abbreviated as friction clutches) that are pressed with springs are widely used in automobiles. The torque emitted by the engine is transmitted to the driven disc through the friction of the contact surface between the flywheel and the pressure plate and the disc disc on the disc plate. When the driver presses the clutch pedal, through the transmission of the parts, the large end of the diaphragm spring drives the pressure plate to move back, and the driven part is separated from the active part at this time.

Hello dear <>

The clutch is an important component in the power transmission system of an automobile, which is mainly responsible for transmitting the power of the engine to the transmission Sakura rental and drive wheels. It accomplishes this by controlling the connection between the engine and the gearbox. Here's how it works:

1.The clutch consists of two parts: a contact part (often referred to as a "clutch disc") and a pressure plate.

The clutch disc is connected to the engine, while the pressure plate is connected to the transmission. 2.When the driver depresses the clutch, the pressure plate will exert pressure on the clutch plate, so that the clutch disc and the pressure plate are in close contact with each other, and the engine speed can be transmitted to the transmission by transmitting the torque, thereby pushing the vehicle forward.

3.When the driver needs to change gears or stop, the clutch needs to be released. At this point, the pressure plate stops applying pressure, the contact between the clutch disc and the pressure plate is disconnected, and the engine and transmission are no longer connected.

In this way, even if the engine is still running, the power spine is not transmitted to the transmission and drive wheels, thus preventing accidents such as driving or stalling. In short, the clutch mainly adjusts the driving state of the vehicle by controlling the connection between the engine and the transmission, so as to achieve smooth shifting and smooth driving.
