Today, we are not joking, but we are going to show you a good idea of what happens in the car, which is the clutch, which is often the head of our classmates。
What's the idea of the clutch? What's the point
After learning about it, perhaps drivers are better placed to learn how to get off the pedal while driving, learn to “depart from the school”, take a driver's license and land successfully。
The role of the 1-chiper
Cut the power for now
The clutch is a component of the vehicle moving system that is directly connected to the engine。
By definition, the clutch can control the “off” and “open” of engines and vehicle transmission systems, i. E. The power of motors can be cut off or transmitted。
At the time of "off" the engine and the transformer can be connected to transmit power for the vehicle; at the time of "out", the connection between the engine and the transformer is severed. At this point, while the engine was still in operation, it was not able to pass the power to the wheel and the car could not move forward。

Imagine if there was no clutch, the engine would always pass to the wheel and drive the wheel forward. When we want to stop temporarily or wait for a red light, we have to turn off the engine, and when we want to drive, we have to re-open it。
More importantly, engines not only drive cars forward, but also provide energy for such important components as brakes, circuit control and air conditioning. Once the engines are out of fire, the components may not be operational, creating a range of safety hazards。
The vehicle therefore needs a component that will both cut the engine power at any time and ensure its continued operation. This part is the clutch。
Adjust twisting
In addition, some of the “composite” characteristics of engines are the essence of the clutch。
Drivers are required to ensure that motors remain close to the optimal speed range, whether they start, stop or travel normally. A sudden increase or decrease in speed can damage engines and other related components。

Owing to the inertia of cars, it takes a lot of effort to get them out of static mode. If it does not coincide at the start, the force will act almost completely on the engine in a moment, creating a significant resistance rectangular。
With the effect of a resistance rectangular, the rate of rotation will be drastically reduced to below the minimum stable rate of rotation (300-500 turns/minute), causing damage to the engine。
It is good that in the present case, the car will automatically shut down to protect itself from harm, but when the car dies, it will suddenly stop and cannot move forward. That's when the clutch works。
At the start, the driver is required to step down the clutch pedal, separate the clutch, break the connection between the development motive and the transmission system, place the transformer on hold, and then gradually release the clutch pedal, so that the compressor may gradually join。
In the process of slow integration, the brakes of the engine gradually increased, and then gradually stepped down the door pedal, increasing the supply of fuel to the engine and keeping the engine at the lowest stable rate of turn-off。
At the same time, the trigger pedals were gradually released so that the power of the engine would be passed on to the wheel, and the twists would gradually increase until the towed force was sufficient to overcome the initial resistance and the car was moving successfully。
Untie the clutch pedal, and power will pass。

Similarly, when the engine is shut down, due to the rigidity of the connection to the moving system, the speed of the engine will decline sharply, generating a high inertial rectangularity that may lead to overloading damage to the moving system. The driver therefore needs to ensure the safe parking of the vehicle as it approaches its stop。
The clutch also plays an important role in the switch. Also restricted by engine performance, the transmission system needs to be changed to a different block to ensure that engine speeds are optimal at different speeds。
Before the change of block, the driver must step down the clutch pedal, interrupt the power transfer, and facilitate the removal of the gears from the original block, while the gears of the new block are gradually synchronized to achieve a smooth switch。
In the absence of a clutch, the gear rotates at a high rate, driven by the engine, and the speed of the old and new gears is difficult to synchronize and does not allow the rods to switch。
Following the power outage, the new slots gradually converged。

2-bed clutch structure
Before explaining the structure of the clutch, we need to make clear that the clutch and the clutch pedal are two concepts。
The clutch pedal refers to another pedal next to the brake pedal. When the driver stepped on the clutch pedal, the pusher moved the piston from the main tank to the left, the oil from the main tank and the pipe was compressed and pressure increased。
The pistons of the tank were also pushed to the left, under pressure, to drive the separation bearing from the clutch and cut the power transmission。
When the driver unties the clutch pedal, the clutch is pressed in the opposite direction to connect the power transmission。
At present, the most common compressor on a vehicle is a friction compressor, which consists mainly of four components: a driver, an oscillator, a pressurizer and a control structure。
The driving component includes a wheel, a clutch cover and a voltage plate. The aerodynamic component consists of a rim and a friction liner; pressure including film springs; the operating mechanism includes the release of poles and forks。
Wheels are engines. When the clutch is connected, the membrane spring, through the voltage, will press the wheel。
There is a friction liner on the drive, and the wheel rotates from the wheel through friction, and from the wheel drives the entire conveyor system。
The split fork is on the wheel from the wheel. When the clutch is separated, the split fork drives from the wheel, overcomes the spring power of the film, separates it from the wheel and cuts the power transmission。
What happened after 3 stepped on the clutch
There are three states of the clutch: the non-connectivity when stepping on the clutch, the complete connectivity when not stepping on the (off) clutch, and the semi-connectivity when partially stepping on the clutch。
Before the car is activated, the driver must step down the clutch pedal to move the film spring drive disk backwards and separate from the wheel。
The driver then stepped on half the clutch. At this point, there is a sliding friction between the wheel and the wheel, which turns at a rate greater than the speed of the output axis, with only part of the engine power being passed to the speedbox。
As the driver gradually unwinds the clutch pedals, under pressure from the film spring, the drive will slowly press towards the wheel and the power to be passed to the wheel gradually increases。
When the vehicle completes its start-up motion and is moving normally along the road, the clutch pedal is released completely and, under pressure from the film spring, presses the wheel from the wheel, which is connected by friction, thus transmitting the power。
In the case of manual blockers, the driver must have the skills to control the clutch in order to have good control of the vehicle and ensure its smooth start and switch。
The auto-block also has a clutch。
Auto-stop cars are now becoming more widespread, which makes many new drivers accustomed to self-blocking “smarts”, without manual operation of the clutch. Some drivers even thought that the auto-blocker did not need a clutch。
In fact, the automatic transformer simply does not have a separate external clutch pedal, but is controlled by a computer. Even the auto-blocked clutches are more numerous than the manual
For example, cars in at gearboxes can change planetary gear combinations in an instant by simultaneously controlling the pressure and disconnection of multiple clutches to achieve an unconscious change effect。
Each level therefore requires a set of adaptors, and a total of multiple sets of adapters are required to achieve an "automated" switch。
There's a lot of clutches in the gearbox。
Different types of auto-block vehicles are equipped with different clutch numbers and functions, which are not presented here。
Seeing this place, are the boys aware? I didn't think the clutch that drove the new driver crazy would do that
