The Design of any car, even with the automatic transmission provides for the presence of such a node as a clutch. The transfer of torque from the flywheel is made through it. However, like any other mechanism, it breaks down. Let's look at a faulty clutch and its variants.
The node performs the function of a momentary disconnection of the engine flywheel and transmission, as well as a smooth contact when pulling away. The clutch controls and prevents excessive load on the host and dampens torque fluctuations. Located between the gearbox and powertrain of the car.
At the moment, regardless of what the installed box, clutch are of three types:
The Principle of operation of this node is as follows. When you pedal, the clutch acts on the clutch release bearing by moving the forks. The penultimate cell pushes on the petal of a spring pressure plate, which then delve into the flywheel side of the engine. Wherein the tangential spring act on the pressure element. As a consequence, cease the transfer of torque from the flywheel to the box. When the driver releases the pedal, special springs uncoil and injected into the slave contact to the pressure plate and flywheel. By the force of friction linings is "lapping" elements – torque transmission is resumed.

One of the most common faults of this node – slip and partial shutdown. In the latter case, when fully depressed the clutch pedal will be difficulty to enable transmission. The course is quite large. If there is slippage, it may be accompanied by a burning smell in the cabin. This is due to the friction linings of the clutch disc on the flywheel. The dynamics of dispersal in this case drops significantly, while fuel consumption – is increasing.
If you're having such trouble with the clutch, to drive such a car every day is forbidden. In extreme cases you can reach a garage or service station. In order to save the node, go carefully, without jerks and podguzova, gently switching speed. Experts recommend in this situation to use a double extraction. Those who learned to drive in the ZIL, are well aware of this technology. Its Essence is as follows. To switch to a higher gear, you need to squeeze the pedal and move the gearshift lever to the neutral position. Further, the pedal release, then press again and already include the desired speed. Gear switch in the same way. The only thing to save the synchronizers, it is recommended to add a little momentum before you turn on by pressing the gas pedal. By the way, this method can be used "the everyday”. Experienced motorists say that the double cutoffs significantly saves the node box and clutch. Especially increases the resource of synchronizers that in this operation work with virtually no loads.
Any Such failure of adhesion occurs due to hard operation of the vehicle. For example, in winter, the car sat “belly” in the snow. Trying to leave this “trap”, the car owner presses hard on the accelerator pedal. The same goes for driving on mud and sand. Stuck there, no need to burn the clutch – so you bury the wheels even more. And, of course, contribute to this sharp starts with cone and drive "to cut". This reduces the disk resource at least three times. But not only this element tends to wear out. Loads also lends itself to the bearing of the clutch. Determine the fault is quite simple. Like any other bearing, it starts to squeal and make other characteristic sounds. When fully depressed the clutch pedal, standing on “neutral”, this sound disappears. But as soon as you take foot in the region of the gear box to reappear squeals. On cars with a clutch cable, it has the ability to stretch.
If “release” came to an end, you do not get fully off the clutch. So to start need. On an idling car and turn the first gear, then start it in gear. If the battery has a good stock charge, you will be able to start and arrive at the first speed to the nearest workshop. While shifting to produce is not recommended. The disk is in constant engagement, so gearbox gear will tolerate heavy loads. Subject to availability, advised to take in tow, or the tow truck. However, some motorists share tips on how to switch from first to second and third without using the clutch. This requires gaining a certain amount of revs – the higher, the better. Then reset the accelerator pedal and without podguzovaincludes the following transmission. If you do not follow the proper moment of momentum, you will hear a distinctive crunch. Therefore, to produce such action is allowed only in an extreme case, failing to call a tow truck or “pull” in tow. With regard to such elements as the clutch cable, it open or sticking can cause the failure of the node. The drive will be located invariably in the same position. If it is hydraulic drive, it is also possible drips of fluid from the actuator. As a consequence, you are having trouble with the clutch like slippage and partial on/off of the transmission.
If the machine is when you start twitching, it is possible to wear several items. It may be sticking on the splines of the hub of the driven disc or wear of the item (damage to the existing pads). Also the jerks occur when the damper springs wear and deformation of the pressure element. What the site came into the fault, determine during disassembly by the presence of mechanical damages and traces of burning.
