Clutch works with semi-linkage tips Date: 2014-10-20 Reading times: 148 Source: Zhejiang Hangtai automotive Components Co.,Ltd

For manual transmission models, the clutch is an important component of automotive power systems, which will be responsible for cutting the connection between the power and the engine. When urban roads or complex road driving, the clutch has become one of our most frequently used parts, and clutch use will directly reflect 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. Clutch by the friction plate, spring plate, pressure plate and the power output shaft composition, disposed between the engine and transmission, to the stored engine flywheel torque transmitted to the gearbox, ensure that the vehicle passes under different driving conditions to the driver wheel driving force and the right amount of torque, is the powertrain category. In the semi-linkage when the power input terminals and power output of the clutch rotational speed difference is allowed, that is, by its rotational speed difference to achieve the right amount of power transmitted.

Clutch is divided into three working condition, that is, not the clutch of full connections, some clutch semi-linkage, and the clutch is not linked. 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 two speed . 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, there would be no relative friction.

The last one, which 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 friction plate clutch pressure plate and flywheel. Flywheel speed is greater than the rotational speed of the output shaft, the power transmission from the flywheel to the transmission out of the partially transmissive. At this point is equivalent to a soft connection status between the engine and the drive wheels.

In general, the clutch is starting to play a role in the vehicle and shift the time between transmission of a shaft and two shaft speed difference this time, the engine power must be cut with a shaft after synchronizer can be a good the rotational speed of a shaft with two shafts to maintain synchronization, after hanging gear, and then will be combined with an engine power through the clutch shaft, so that power continues to be transmitted.

In the clutch, there is an essential cushioning device, which consists of two discs together is similar to the flywheel, on the disk playing a rectangular recess, the spring is disposed in the groove, in the face of fierce when the impact, the spring between the two discs mutually resilient action occurs, the buffer external stimuli. Effective protection of the engine and clutch. The various parts of the clutch, the intensity of the pressure plate spring, the friction coefficient of friction plates, the diameter of the clutch, the clutch friction plate position and the number of the key factors that determine the performance of the clutch, the greater the stiffness of the spring, the higher the friction coefficient of the friction plate, the larger the diameter of the clutch, clutch the better the performance.

Know the principle, we in everyday driving, when the proper use of the clutch it? According to the above-mentioned principles are not linked and do not need any full-linkage techniques. The real test of skill, there are some errors in the operation of daily driving, are linked in a semi-state of the clutch. Therefore, the use of the clutch semi-linkage technique actually use skill.

Need to have some time at the start of the semi-linkage in order to ensure a smooth start. Sit Beginners cars have such an experience, or turn off the start, either Yichanyichan out, these are the semi-linkage skills not mastered a good performance. The car started, two gearbox shaft is still, when we hang a block before, you need to depress the clutch, then the gearbox shaft and a separate power through the synchronizer hang a block later, a shaft also Similarly becomes stationary. Out power from the flywheel there is a certain speed, this time with a rotational speed of the shaft there is a huge difference, which is much higher than the start time for that half linkage for shifting the main reason for the request, a stationary clutch member before and after a movement.

Such a speed difference must be digested by the semi-linkage, which is part of the beginning, when power passed to a shaft, so that the vehicle can be started with a more stable stance, once the vehicle up, the speed difference becomes very small, The the clutch is fully lifted, there would be impacted.

Semi-linkage technique requires high start ramp. Semi-linkage can digest the engine speed and the 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, it will pull up the handbrake at the start ramp, and then let the clutch linkage in a semi-state, Panasonic handbrake, the vehicle remains stationary, anti-slip car adverse impacts to the car. The gravity of the vehicle sliding backwards is provided by the engine power to contend with, and 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 began to smooth slope. This time for semi-linkage techniques are higher, if the semi-linkage too weak, it could slide backwards in the vehicle when the handbrake is released, likely to cause panic novice, semi-linkage if the intensity is too strong acceleration of the vehicle is easy 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 a 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 a number of methods of operation appear detrimental to the clutch 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 as a result of tight oil from the well, afraid of their own off the car stalled at the start, so they bang the throttle and the clutch was low, long time do not achieve full linkage lift all this time the engine speed and a rotational speed of the shaft there is a huge difference in rotational speed, and the vehicle is started slowly, all these huge difference in rotational speed by half linkage digested clutch, which clutch is destroyed practice. In order to avoid frequent start ramp, feet and a half step on the clutch, semi-linkage can be controlled so that the traveling speed of the car, which is commonly known as the 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 the 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 actions will accelerate the wear of the clutch plate on the vehicle's power and economy will result in losses.

Certain special road, rational use of semi-linkage allows the vehicle turnaround. In addition to half-time start-up and shift linkage required, under certain conditions is also used to semi-linkage. When we are all linked conditions in a block, can not get enough power, you can borrow half linkage principle play engine performance.

For example, when driving on steep slopes, we stop at a state-wide linkage uphill, at this time, if the engine speed is low, then we can use the semi-linkage method, the first step on the clutch in the end, and then the engine speed vigorously enhance oil boom the maximum torque of the engine speed range above, quickly raised his left foot from the clutch pedal, but note that not all of the lift, but jumping semi-linked state. At this point the engine can play a huge torque, the torque distribution to the wheels through a gradual clutch semi-linkage to help rescue vehicles. Note that, in this case can only help to enhance the speed semi-linkage of the vehicle, for a long time will remain above state ablation clutch plate.

In addition to the ramp, like the wheels into the sand and other road conditions, require a significant torque to the wheel is rotated to be pulled up speed by using semi-linkage longer to achieve maximum torque delivery.

Clutch is a frequent friction car parts, it will increase the use of time and frequency of use and produces wear, it will have the clutch slipping. For experienced drivers can be found early, such as judging whether the slip clutch in place of the car, we can link into a block, then do not loose the hand brake, then slowly lift the clutch until it is completely lifted, you lift the clutch when the engine flameout This proves that you do not slip clutch, anyway, if the clutch is completely lifted and the car does not turn off the clutch to prove that you have a problem.

There is clearly felt at the start clutch position suddenly becomes high, and also the precursor of clutch slip, then there is only when we feel hard acceleration in rising engine speed, and the speed has not increased, and so these cases are clutch slip sign. When worn or slipping clutch when we should be promptly checked, replaced, or else it would not be effective engine output power is transmitted to the output shaft, but the loss of power sliding friction between the clutch plate and the flywheel, and friction between them into heat energy consumed, this will lead to decline in power transmission, while the cost of oil will increase the cost of car.
