Clutch - Principle

 Clutch - works：
Active part and the driven part by the friction clutch between the contact surfaces, or with magnetic drive (electromagnetic clutch) to transmit torque as the transmission medium with a liquid (hydraulic coupling), or that can be between temporary separation, but also increasingly engaging in the transmission process has two parts to allow mutual rotation.
Currently widely used in the automobile is spring-loaded friction clutch (referred to as a friction clutch).
Torque of the engine emitted by friction flywheel and pressure plate and driven plate contact surface, passed driven disc. When the driver depresses the car clutch pedal, by passing the parts of the diaphragm spring pressure to drive the big end late shift, this time driven part and active part of the separation.

Clutch - operating essentials：
Car Clutch operation three essentials: a fast, two slow, three linkage. When lifting the clutch pedal, they have to follow, "a fast, two slow, three-linkage" operating principle. Start when the clutch pedal action to neat, kick in the end, the clutch completely separated. The so-called "a fast, two slow, three linkage" to lift the clutch pedal is in the process in three stages, beginning quick lift, when the clutch pressure plate gradually feel bound to the semi-linkage, the pedal to lift the rate began to slow down, in the semi-linkage to the fully integrated process, the clutch pedal is slowly lifted. At the same time lift the clutch pedal, the engine power should be based on the size of the accelerator pedal gradually and then go on to make the car can be started smoothly. To smooth the proper operation of the accelerator, the clutch is fully integrated only in order to increase the throttle.

Clutch - Principle：
For manual transmission models , the car clutch is an important component of automotive power systems , which will be charged with cutting off the connection between the power and the engine . When the complexity of urban road or road driving, the clutch has become one of the most frequent our part , good or bad use of the clutch , directly reflects the level of the driver , the vehicle also played a protective effect . How to properly use the clutch , clutch master principle to use the clutch in exceptional circumstances to solve the problem , each driving a manual transmission car riders should grasp.
The so-called clutch , by definition means that the use of " off " and "close" to deliver the right amount of power . The clutch friction plate , a spring , pressure plate and the power output shaft component , which is located between the engine and gearbox , the engine is used to store the flywheel torque transmitted to the gearbox , in order to ensure delivery to the vehicle under different driving conditions wheels right amount of driving force and torque belong powertrain category. In the semi-linkage , when the power input and power output of the clutch rotational speed difference is allowed , the speed difference is achieved by the amount of transmitted power .
Clutch is divided into three working state, that depresses the clutch does not even move, do not depress the clutch all- connections, as well as some clutch semi- linkage . When the vehicle is started, the driver depresses the clutch , the clutch pedal movement to pull back against the pressure plate , which is separated from the pressure plate and friction plate , pressure plate and flywheel at this time no contact , does not exist relative friction . When the vehicle is in normal driving , the pressure plate is squeezed tightly against the flywheel friction plate on , then remained relatively static friction between the friction maximum input shaft and output shaft between the pressure plate and friction plate , the same speed both . The last one is the state of semi-linked clutch , pressure plate and friction disc friction less than full -linked state. At this point, between the clutch pressure plate and flywheel friction plate on the sliding friction state , the flywheel speed is greater than the rotational speed of the output shaft of the transmission of power from the flywheel out part passed to the gearbox . In this state , a state equivalent to a soft connection between the engine and the drive wheels .
Generally , play a role in the car clutch and shift the vehicle starting when the transmission between the shaft and a second shaft rotational speed difference at this time , the engine power must be cut with a shaft after the synchronizer to good the rotational speed of a shaft with two shaft synchronized . After hanging up the gear , and then through a clutch shaft combined with engine power , so that power continues to be transmitted. In the clutch , there is an essential buffer device . It is similar to the flywheel by two discs are brought together , the disc playing in a rectangular recess disposed in the spring recess in the face of fierce impact resilience of the spring to each other occurs between two discs by the buffer to external stimuli , the effective protection of the engine and the clutch .

The various parts of the clutch , the friction coefficient of the intensity of the pressure plate springs and the friction plate , the clutch position of the clutch and the number of diameters , the clutch friction plate is to determine the performance of the key factors. Spring stiffness , the higher the coefficient of friction of the friction plate , the greater the diameter of the clutch , the clutch , the better the performance .
