     For manual transmission models, the clutch is an important component of automotive power systems, which bears will be cut off and the connection between the power and the engine work. When the complexity of urban roads or road driving, the clutch has become one of our most frequently used parts, and the clutch is good or bad use, directly reflects the level of the driver, but also reflects the quality of protection for the vehicle. Proper use of clutch, clutch master principle to use the clutch in exceptional circumstances to solve the problem, each driving a manual transmission car riders should master.
     The so-called clutch, by definition means that the use of "off" and "together" to deliver the right amount of power. The clutch friction plate, the spring plate, the pressure plate and the power output shaft of the composition disposed between the engine and the transmission, to the stored torque transmission flywheel of the engine to the transmission to ensure that the vehicle passes under different driving conditions to the driver wheel right amount of driving force and torque, belonging to the powertrain category. In the semi-linkage when the power input terminal and power output terminal of the clutch rotational speed difference is allowed, that is, by its rotational speed difference between the right amount of power to achieve the transfer.
     Clutch is divided into three working state, that does not depress the clutch, move the whole company, part of the clutch semi-linked, and the clutch is not even move. 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 the output shaft between the pressure plate and friction plate, the same speed both . When the vehicle is started, the driver depresses the clutch, pull the clutch pedal movement platen lean back, which is separated from the pressure plate and friction plate, pressure plate and flywheel at this time do not touch, it does not exist relative friction.
     The last one, that is, the clutch semi-linked state. At this point, the pressure plate and friction plate friction less than full-linked state. Sliding friction between states and friction plate clutch pressure plate on the flywheel. The flywheel speed is greater than the rotational speed of the output shaft, the power transmission portion is passed out from the flywheel to the transmission. At this point is equivalent to a soft connection status between the engine and the drive wheels.
     In general, the clutch is to play the role of the vehicle start-up and shift time between the transmission shaft and a second shaft rotational speed difference at this time, the engine power must be cut with a shaft after the synchronizer can be very good will maintain the speed of a shaft with two axes simultaneously, after hanging up the gear, and then the engine power combined with a shaft through a clutch, so that power continues to be transmitted.
     The clutch, there is an essential cushioning device, which is similar to the flywheel by two discs are brought together, the disc playing in a rectangular groove, a spring is disposed in the groove, in the face of fierce when the impact occurs between two discs of the spring elasticity of the each buffer external stimuli. Effective protection of the engine and clutch. The various parts of the clutch, the intensity of the pressure plate spring, friction coefficient of the friction plate, the diameter of the clutch, the clutch friction plate and the number is the position of the key factors determining the performance of the clutch, the greater stiffness of the spring, the higher the coefficient of friction of the friction plate, the larger the diameter of the clutch, the clutch, the better the performance.
     Know the principle, we in daily driving time how to properly use the clutch? According to the above-mentioned principles are not linked and full linkage does not require any skill. The real test of skill, there are some errors in the operation of daily driving, are linked in a semi-state of the clutch. So clutch semi-linkage using techniques actually use skill.
     Need to have some time at the start of the semi-linkage, in order to ensure a smooth start. Sit novice to open the car have such an experience, or turn off the start, either Yichanyichan out, these are semi-linkage skills not mastered good performance. The car started, gearbox two shaft is stationary, when we hang a block before, you need to depress the clutch, this time a shaft gearbox and power separately, by synchronizing the device to hang a block later, a shaft also Similarly becomes stationary. Out of power from the flywheel there is a certain rotational speed, then the rotational speed of a shaft there is a huge difference, which is much higher than the start time for that request to shift the main semi-linkage, a stationary clutch member before a movement.
     Semi-linkage techniques require high start ramp. Semi-linkage can be digested and the speed of the engine rotational speed difference between the wheels, which means that the power may have been transmitted to the wheels, but the operation of the wheel does not occur, which often occurs in the ramp. Generally unskilled driver for driving is concerned, would pull the handbrake at the start ramp, and then let the clutch linkage in a semi-state, Panasonic hand brake, the vehicle remains stationary, anti-slip car bring disaster to the car. The gravity of the vehicle is sliding backwards by the power supplied to the engine to compete, but the clutch is responsible for the elimination of the presence here of the speed difference.
     Vehicles in this case, the driver will be able to easily start, and continue to depress the accelerator pedal so that further enhance the speed to get enough torque, the vehicle on a smooth slope from the. This time for the semi-linkage techniques are higher, if the semi-linkage too weak, it could slide backwards when the vehicle release the handbrake, the novice is likely to cause panic, if half the intensity is too strong linkage acceleration of the vehicle is liable to be excessive and hit the vehicle in front. So for starters, then you can let the engine speed is slightly higher, and the use of large semi-linkage efforts, the vehicle has a tendency to move forward, the re-release the handbrake.
     Novice drivers when there will be some errors on the use of operating the clutch. As a novice, due to unskilled driving skills, it is difficult to fit the oil from the well, resulting in some of the methods of operation lossy clutch appear when using the clutch, and these cases also appear in the semi-linkage of the time.
     Avoid prolonged clutch linkage in a semi-state in order to effectively protect the clutch. Some novice just on the road due to the tight oil from the well, afraid of their own at the start stalled off the car, so they bang the throttle while the clutch was low, long time do not all achieve full lift linkage, then the engine a shaft rotation speed and there is a huge difference in the rotational speed, and the vehicle is started slowly, the great difference in rotational speed of all the half-clutch linkage digest, which is destroyed clutch approach. In order to avoid frequent start ramp, foot and a half step on the clutch, so the linkage can be used to control the car's half speed, which is commonly known costumes clutch go.
     The whole process is sliding friction clutch, which can also damage the long sliding friction clutch. Driving down the road always like to put his left foot on the clutch pedal, causing unconscious depressed the clutch pedal, the vehicle for a long time in a state of semi-linkage. All of these operations will be accelerated wear of clutch plates on a vehicle's power and economy will result in losses.
     Some special road, rational use of semi-linkage allows the vehicle turnaround. In addition to shifting needs during start-up and semi-linkage, under certain conditions also make use of the semi-linkage. When we are all linked conditions in a block, can not get enough power, you can borrow half the principle of linkage play engine performance.
     For example, when driving on steep slopes, we stop at a state-wide linkage uphill, if the engine speed is low at this time (because of slow speed, the front corners too fast or have a car stop leads to deceleration, etc.), then we can use semi-linkage method, the first clutch foot in the end, and then the oil boom will be vigorously promoted to engine speed above the maximum torque of the engine speed range, quickly raised his left foot from the clutch pedal, but note that not all of the lift, but jumping half linkage state. At this point the engine can play a huge torque of the torque distribution to the wheels through a progressive linkage clutch half, helping the rescue vehicle. Note that, in this case can only help to enhance the speed of the vehicle semi-linkage, the state will be maintained over long ablation clutch plate.
