What are the benefits of changing the clutch plate in the car

1. Ensure a smooth start of the car.

This is the clutch.

The primary function. Before the car starts, it is natural to start the engine first. Whereas, when the car starts, the car accelerates gradually from a completely stationary state. If the drivetrain (which links the entire car) is rigidly connected to the engine, then the transmission.

As soon as the gear is engaged, the car will suddenly rush forward, but it will not be able to start. This is because when the car moves from a standstill to a forward thrust, it generates a large inertial force.

It causes a lot of drag torque to the engine. Under the action of this inertial drag torque, the engine speed drops sharply to below the minimum stable speed (generally 300-500rpm) in an instantaneous time, and the engine is turned off and cannot work, and of course, the car cannot start.

That's why we need the help of the clutch. 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, resulting in traction.

When it is enough to overcome the starting resistance, the car starts to move from a standstill and accelerates gradually2 to ensure that the drive train works smoothly when shifting gears.

2: Achieve smooth 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. Before shifting gears, the clutch pedal must be stepped on, 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 meshing can be greatly reduced, and a smooth shift can be realized.

3. Prevent overload of the drive train.

When the car applies emergency braking.

If there is no clutch, the engine will be rigidly connected with the drive train and the speed will be drastically reduced, so all the moving parts will produce a large moment of inertia (its value may greatly exceed the maximum torque emitted by the engine when it is working normally, causing a load that exceeds its bearing capacity to the drive train, and causing damage to the parts. With a clutch, it is possible to rely on the relative movement that may occur between the active and driven parts of the clutch.

to eliminate this danger. Therefore, we need a clutch to limit the maximum torque that the drivetrain can withstand and ensure safety.

Clutches can be divided into: friction clutches, or the use of liquid as the transmission medium (i.e., fluid couplings.

The clutch is easy to use and is not easy to damage the pressure plate.

Changing the clutch plate in a car is quite complicated, and it takes about three or four hours to replace the clutch plate.

The reason why it takes so long is because replacing the clutch plates requires the gearbox.

Hang down. The crane gearbox can be said to be a big project in the automobile maintenance industry, no two or three people can not do it completely, and the gearbox also needs to be around the engine compartment, such as the battery.

Remove fuse boxes, cables, and all other parts that hinder work. It's still a lot of work. After the gearbox was successfully lifted, the engine was hoisted in the engine compartment through the bracket, and the clutch plates could be easily removed at this time.

At present, most 4S shops replace the clutch plate with the clutch pressure plate.

What do I need to pay attention to when replacing a clutch? The small attention is paid to the fact that the spline grooves of the two friction plates are consistent for the installation of the clutch, and the big attention is to improve the safety of the gearbox. I'll take the precautions for replacing the clutch of the truck liberation vehicle as an example.

At present, there are many kinds of clutches, such as dry clutches, wet clutches, electromagnetic clutches, hollow shaft magnetic powder clutches, etc.

Different types of clutches have different structures and precautions, and automotive double-disc clutches include driven discs (i.e., clutch plates), intermediate pressure plates, pressure plates, release bearings, etc. The clutch is mounted on the flywheel of the engine. Clutches are divided into single-plate clutches and double-plate clutches.

Before installing the double-plate clutch, check whether each component meets the required value. Before installation, grease the needle roller bearing in the center of the flywheel, place the long end of the first clutch plate spline forward, that is, close to the flywheel side, and then install the middle pressure plate.

The medium pressure plate must be checked whether it can move freely on the stru, and also check whether the free height of the three return springs of the middle pressure plate is higher than that of the middle pressure plate, and whether the length of the three return springs is equal. Secondly, install the second friction plate, and place the long end of the spline groove on the friction plate on the rear side (near the gearbox), otherwise the thickness of the two friction plates will exceed the thickness of the intermediate pressure plate, causing installation errors and rework. Then install the clutch.

Now insert a "fourth gear", the first shaft of the transmission, on the two clutch friction plates, and insert the front end into the roller bearing in the center of the flywheel before tightening the clutch mounting bolts. When installing the gearbox, the clutch friction plates can be easily inserted only after installation.

Adjust the clutch release bearing clearance and clutch friction plate release clearance. Once the requirements are met correctly, the installation is complete. The pressure plate of the clutch is made of metal steel, and the driven plate, that is, the clutch friction plate, is riveted by steel plate, spline groove and friction plate (asbestos plus metal wire).

The thrust of the clutch spring is applied to the friction plate by the middle pressure plate, which is smooth, and the friction coefficient of the soft material of the friction plate is large, which is convenient for the engagement and separation of the clutch.

First of all, we must pay attention to safety, and we must do our best in the later processing, so as to avoid problems in the later stage.

Be sure to choose the right clutch plate for yourself, which is very important, related to your own safety, it is best to choose the highest clutch plate, such a clutch plate is more secure.

Be sure to choose the original clutch, and be sure to choose high quality, don't choose poor quality, be sure to go to a regular repair shop to change.

When the clutch plate of the car is broken, the clutch will shake, slip, abnormal noise, incomplete separation and other phenomena.

1. Clutch shake.

1. When the vehicle starts, although great attention is paid to slow refueling and slow release of the clutch pedal, the vehicle still cannot start smoothly and there is an impulsive phenomenon. This is because the clutch is engaged with shaky and unstable, which causes the vehicle to start unsteadily.

2. Causes.

1) The separation lever is improperly adjusted or deformed, so that the contact between the three separation levers and the separation bearing is not stable.

2) The vibration damping bullet of the clutch driven disc is too weak or broken, and it cannot play a good damping role.

3) Separate the wear and lack of oil in the bearing seat, resulting in inflexible movement.

4) The connecting bolts of the flywheel casing, transmission, etc. are loose, the engine is poorly fixed or the damping rubber pad is damaged, and the connecting bolts fall off.

5) The clutch disc steel plate is warped and cracked, and the flywheel working surface is worn and grooved.

6) Individual pressure plate springs are too soft or broken, or the elastic force is uneven.

7) The spline of the driven disc is seriously worn. One shaft of the transmission is bent or the spline of one shaft is corroded with the spline of the driven disk, which makes the driven disc stuck.

Second, the clutch slips.

1. Phenomenon. 1) When the car starts, the clutch pedal is raised very high, and it can't start yet, and when the pedal is fully raised, it can barely start.

2) When the car accelerates, the speed can not be increased with the increase of the engine speed, so that the car is weak, especially when the uphill slope is more obvious, when the car is seriously skidding, there is a scorching smell, smoke, and even burn the friction plate.

2. The cause of the failure.

1) The pedal has no free stroke, so that the release lever is normally pressed on the release bearing, and the clutch is in a semi-disengaged state.

2) The connecting bolts between the clutch cover and the flywheel are loose, the friction plate is thinned due to grinding and hail, and the compression spring is too soft.

3) The friction plate is oily, hardened, and the rivet is exposed.

3. Clutch abnormal noise.

1. When the engine is idling, there is an abnormal sound when the clutch pedal is stepped on, and the sound of the relaxation pedal disappears; Sometimes there is an abnormal sound whether the clutch is engaged or disengaged.

2. Causes.

1) Separation bearing is poorly lubricated, loose, sintered or stuck.

2) The return spring of the separating bearing seat is too soft, broken or falling off.

3) There is no free stroke on the clutch pedal.

4) The height of the separation lever is different, or its bracket and pin hole are worn and loose.

5) Separate fork stagnation or separation bearing seat stagnation.

6) The pressure plate and clutch cover fit loosely.

7) The friction plate is hardened and cracked, or the rivet of the friction plate is exposed.

8) The clutch shell is out of tolerance with the crankshaft centerline.

Fourth, the clutch separation is not complete.

The engine is idling, pressing the clutch pedal, there is a gear impact sound when the gear is in place, and it is difficult to hook in, and in serious cases, it will cause the engine to stall.

Changing the clutch plate frequently has no effect on the car. The clutch is a mechanism that transmits power by means of two clutch friction plates with flat surfaces, which are axially compressed and released.

The greater the axial pressure of the two clutch plates, the greater the friction generated and the smoother and more normal the operation transmitted to the extruder. Under normal operating conditions, the machine generally runs smoothly and noiselessly.

Under the rated load, the clutch plate will not slip, will not stuck, will not detach itself, and at the same time, after the clutch plate is separated, it should also be separated completely to stop the brick machine, and there will be no other noise or two clutch plates are not completely separated.

Therefore, it is necessary to adjust the clutch plate gap in the clutch, a large gap will cause the clutch plate to slip, damage the clutch plate, and a small gap will make the clutch plate not easy to separate.

Summary. In this case, it belongs to the warranty during the warranty period, if there is a problem with the clutch master cylinder or the clutch cylinder, it can be replaced free of charge, if there is a problem with the gearbox, this can also be replaced free of charge during the warranty period.

Hello, happy to answer your questions.

If the clutch plate is often replaced, this is the need to check the source to rent the clutch pressure plate to see if there is a problem, if the wear is relatively large, it will also lead to greater clutch wear than the crack, and the need to check the clutch master cylinder, as well as the clutch cylinder, to see if there is a problem, mainly to check these aspects of the inspection hall bridge.

Why does my little car often touch the clutch plates.

I just bought a new car, Beijing Hyundai Solun Bend Yuedong only drove 10,000 kilometers and went to the S store to change the clutch three-piece set: when I arrived at 10,000 kilometers, I changed the clutch three-piece set. By 7:

6. I changed the three-piece set of the departed stuffy device. Walking to 10,000 kilometers the clutch is gone: what is the reason for this.

It is necessary to check the pressure plate of the state He clutch to see if there is a problem, if there is no Zen closure judgment of the He Reform problem, then it is necessary to check the clutch master cylinder and the clutch cylinder.

Why is the old bad clutch plate: I changed the original car parts: I am driving imitation habit problem: it should be said that I am a 40-year-old driver: I have never been half-equipped with a sock clutch. Excuse me, is there a problem with the socks in the car I bought?

Every time I change the clutch: crankset: bearing three-piece set.

This is mainly due to the quality of the vehicle, there is a problem with the rent, there may be a problem in the gearbox, and the gap between the corners is relatively large, which will also cause the clutch to wear out faster.

Excuse me: old change clutch: such as clutch master cylinder and sub cylinder is there a problem: if there is a problem with the gearbox: how to solve it:

In this case, it is a warranty during the warranty period, if there is a problem with the clutch master cylinder or the clutch sub-cylinder, it can be replaced free of charge, if the gearbox is problematic, this trillion or trace can also be replaced free of charge during the warranty period.

When I bought it back for a year, after driving a kilometer and the car broke down: towed to the s shop: it said that the clutch was only insured for 5000 kilometers:

It said that it was my driver's problem with the old banquet: S shopkeeper paid to watch me drive, and he said that I didn't ask the question: and said that it would be better if it was worse this time:

But 30,000 kilometers and the clutch again. Later, I changed it twice outside: it didn't work:

I only walk more than 10,000 kilometers each time: the clutch three-piece set I changed is the Aures brand: Q, is Aures the original car parts?

This brand is the clutch of the original Xunlian number factory, there is no big problem with this clutch, now the main thing is to check the clutch master pump, as well as the clutch sub-pump, and the need to check the variable speed call box.

Socio-economic development is getting faster and faster, people's demand for the use of cars is also increasing, many families will buy a car or even two cars, to facilitate their own life, we will also encounter such and such problems in the process of using carsThe main purpose of the car clutch plate is to cut off the power output of the engineThe correct use of clutch plates can better protect our life safety.

When we drive in life, we must also learn to observe the wear and tear of the clutch plate, if there is serious wear, cracking, scorching, crushing, etc., we must not operate with illness, we must go to the nearest repair shop in time to deal with it in order to better protect our life safety, at the same time, we need to pay attention to the use of the car, for the other parts of the bicycle should also be repaired and maintained in a timely manner, only in this way can we better protect our life safety.

Because we all know that once the car has an accident, it will cause property damage and endanger our life safety, I hope everyone can know this, when buying a clutch, we must pay attention to the quality of the clutch plate, because we all know that there are a lot of unscrupulous merchants who will not care about its quality when they are the first thing, only care about whether he makes money.

For the selection of clutch plates, we should pay attention to the surface must not have deformation, warping and poor tightness of the clutch plate can not be selected, if once the clutch slippage, it will affect other parts, for the maintenance of the car, we should also go to the professional 4S shop for maintenance, only in this way will not have an impact on our vehicles, I hope everyone can know this, at the same time we need to pay attention to the fact that when assembling the clutch plate, Be sure to pay attention to cleaning the grease sludge and other debris on the clutch plate, if the fit is not high enough, it will affect the work efficiency very much.
