Device clutch car service

Strength is necessary for the short end of the engine and transmission connect them carefully when starting the vehicle from the place, as well as in the case when you switch programs. Clutch consists of a clutch mechanism and drive. In the article "Vehicle traction device (service)" we will tell you how to work the clutch on the car, its basic problems and methods to solve them. The hydraulic drive clutch and the clutch mechanism consists of the following elements: a primary shaft gearbox input shaft gear, clutch, clutch pedal, master cylinder, pipe, slave cylinder, clutch fork, pressure plate bearing, release lever, pressure springs, clutch housing ; pressure plate, clutch disc, flywheel, transmission housing, the crankshaft. Drive (hydraulic type) clutch consists of: pipelines push bearing clutch fork, slave cylinder, master cylinder, pedal. When you press the clutch pedal, foot effort the driver through the piston and rod, transmission fluid, in turn, transmits the pressure from the piston on the piston of the main working cylinder. After which the working cylinder rod moves the pressure plate bearing and clutch release fork, which transmits force to the clutch mechanism itself. When the motorist will release the pedal, then the impact of the return spring all the parts back to their original positions. The mechanism of adhesion adhesion mechanism - a device which transmits the torque through the work of friction. That's the clutch mechanism can allow short-term disconnect the gearbox and engine, and later again gently to combine. In addition, the clutch protects the transmission mechanisms from overload. If the engine crankshaft rotates unevenly, there are variations in the transmission. To repay them in the clutch there is a damper or vibration dampers. Elements of the mechanism is always enclosed in a clutch, which is attached to the crankcase. Clutch mechanism itself consists of such elements: the clutch disc to damper vibrations and special wear-resistant linings. pressure plate with the springs, the leading disk (which is the flywheel of the engine crankshaft), the housing and the crankcase. Clutch disc, permanently connected to input shaft transmission, and all the while under the influence of the strong spring is pressed against the flywheel with a pressure plate. Due to the large frictional forces between the flywheel, pressure plate and clutch disc it all as a whole rotates with the motor. However, this happens even when you do not touch the clutch pedal, regardless of whether standing still or riding your car. And for the beginning of the car, it is necessary to press the clutch disc which is connected to driving wheels (through the primary shaft of the gearbox and other drivetrain components) to the flywheel, which rotates, in other words - turn on the clutch. How to squeeze the clutch? To start priotpuskaem pedal, thus giving an opportunity to tighten the pressure plate springs, the clutch disc to the flywheel until they are slightly out of touch. Because of the friction drive for a while, slipping onto the flywheel, will also begin its rotation, and your machine is slowly moving. Then a couple of seconds, push the clutch pedal is somewhere in order to speed disk and the flywheel called. Car while slightly increasing the speed of his movement. And finally, when the flywheel with the driven and the pressure plate is rotating with no slippage at the same speed, fully paying the torque to the gearbox and then to the driving wheels car can only take your foot off the clutch pedal and then completely let go of it. If in the beginning of the way the clutch pedal snapped, the car "jump" forward, and the motor stops. In a worst case, break something else, since such a moment may arise a strong shock wave, multiply the load on all the transmission components and mechanisms of the motor. To turn off the clutch driver presses the pedal, while the pressure plate, moving away from the flywheel releases the clutch disc, interrupting this transmission of torque from the motor to the gearbox. Pressing the clutch pedal to be fast enough, however, is not sharp - a quiet movement to the limit of the pedal. Major damage the clutch. Strength is not completely off ("leads") because of the bias pressure plate bearing a large freewheel clutch pedal, broken springs or warping slave drive. In order to solve the problem should be adjusted pedal, replace broken and springs and wheels and remove the air from the hydraulic actuator. Strength of not entirely ("stalling") due to the small freewheel pedals, broken springs, wear and lubrication of friction plates slave drive. To solve the problem need to adjust pedal, to change or wash the spring drives. Strength turn very sharply because of scoring on the surfaces of the working discs, flywheel, jamming in the mechanism by damaging friction linings slave drive. To solve the problem, replace the clutch disc, remove scratches on the disc surface, replace the defective drive components. Could leak brake fluid in the drive clutch of a worker or a master cylinder, as well as the connecting pipes. To correct the problem should be visually find the leak and replace defective components, followed by removal from it of air (flushing of all hydraulic). How to operate the clutch. When operating the machine must periodically check the level in the barrel, which supplies hydraulic fluid drive coupling mechanism. In the event that the level was below the norm, it must be corrected by refilling the brake fluid. In the worst case, if the level drops to zero, your effort on the clutch pedal will not have to be transmitted. Improper adjustment clutch or reduced level of fluid can lead to the fact that the transfer on your car will be integrated with great effort or not at all be included. And if, while holding the clutch pedal until the end, you'll still be able to "squeeze out" first gear, the car will slowly roll spontaneously, although at the moment the engine still has to be separated from the axis of the wheels. How can this happen and why the car is going? This trouble is called - is the clutch. The essence of this is as follows. At a time when the clutch disc not seem to have contact with the flywheel, it did him little clings, and thus some of the torque will be transferred to the shaft of the gearbox and then to the driving wheels. Happens with the clutch and trouble of another sort. As a result of the fact that when you release the clutch pedal, we urge both sides of the disk (slave) is strongly rubbed against iron pressure plate and flywheel, the lateral surface of the disk will eventually be worn. This process is normal, it provides machine design, so the clutch disc - it's consumable. But there comes a time when the clutch pedal and the top and first gear engaged, and gazuete "you fairly. However, the wear pads on the slave drive is already at a level that now it is not clamped between the pressure plate and flywheel with the required effort, and scrolling, with no transfers torque from the engine to the transmission. This phenomenon is called experts - stalling the clutch. Naturally, there is described an example of very very blind and deaf driver because the car much earlier "warned" him that such an incident may occur. Previously, the approach to the wear limit, the clutch disc was stalled, first in fourth gear, then in third gear, etc. Start the wear limit is easily determined, moving to fourth gear at a speed of 45 - 50 km / h. If you slam on the gas pedal speed motor start to rise, and the car continues to move at a constant rate, then the confirmation of hunches you still smell the smell of "burn" pads on the disk. Consequently, it is time to replace it. If you hear a "whisper" in the clutch or when full pressure is lost, the cost to think about replacing the release bearing device in the clutch the car. Maintenance, the machine is not such a simple, faster and jump-start the machine, all these are the first signs that it's time to check inspection of all arrangements.
