If you want to stop when the speed is fast, does it matter if you step on the clutch first and then

If you want to stop when the speed is fast, you must slow down first, that is, first step on the brake to slow down, and then step on the clutch to pick up neutral to park, otherwise it will be dangerous because of too much inertia.

1. The correct driving method, if you don't stop and don't shift, you don't need to step on the clutch, you should step on the brake first when you slow down, and if the speed drops a lot, step on the clutch to change gears. Frequent clutch pedaling is detrimental to your car; 2. You should step on the brakes first, wait for the speed to drop to thirty or forty yards, and then change the appropriate gear; 3. Deceleration should be treated on a case-by-case basis, and driving should be "predictable". From a distance, I saw that there was a need to slow down, and at this time it was neither the brakes nor the clutch.

Instead, the throttle should be released. At this point, the engine electronic control unit (ECU) stops injecting fuel. The car dragged the engine due to inertia.

This state is called "engine braking". It has two major advantages: fuel economy and low wear on the braking system.

This is the best way to slow down. Of course, you still have to apply the brakes when you get close to stopping at the end. Bad braking and clutch pedaling are harmful to the car.

But it's the brakes that matter a lot. So don't think about it in an emergency (when the speed is not too high). Let's step on it together, there's no big problem.

At high speeds, apply the brakes gently. Unless it's either a collision or the possibility of skidding caused by sudden braking. After the speed of the vehicle is reduced, the clutch should be pressed in time.

Otherwise, the crankshaft, connecting rod, and piston will also make you feel distressed when they hit each other. Even if you press the clutch to the end at high speed, there is no damage to the clutch itself, but if you release the clutch again, then if you don't control the engine speed according to the vehicle speed, the clutch will wear out; 4. When decelerating at high speed, you can't step on the clutch, only step on the brake. 5. If the speed is too high, stepping on the clutch increases the inertia of the car, and the brake should be stepped on first, and the clutch should be stepped on when it is about to stop or the engine is trembling; 6. Traffic jams on urban roads are sometimes very slow, so it is best to deal with them like this

Hang a gear, release the clutch, so that the car starts, and then step on the clutch, at this time the car is equivalent to sliding in neutral gear, and then according to the speed of the car in front of the appropriate brake adjustment. Feel that the speed of the car is slow, and the distance between the car in front needs to be shortened, and then release the clutch to accelerate the car, after the speed comes up, the distance between the car in front is very close, the speed is faster than the car in front, and then step on the clutch to cut off the power, (equivalent to coasting in neutral). You just can't use semi-linkage for a long time.

The state of the semi-linkage is very detrimental to the clutch.

You can press the clutch first, but you can only apply the brakes first, and if you press the clutch first, it will shine into the car faster.

Apply the brakes directly and wait for the speed to drop low enough before pressing the clutch, which can make full use of the engine's power reaction to slow down.

It doesn't matter, if you want to stop quickly, you have to do this, and if you slow down, you have to brake first.

1.The first case: the speed of the car is fast, brake first and then leave.

Brake pedal braking is equivalent to the braking system and braking system acting at the same time, and the clutch downshift is applied when the engine speed reaches idle speed, which is done to prevent the engine from stalling. Pressing the clutch is equivalent to disengaging the engine from the transmission system, which is equivalent to coasting in neutral.

2.In the second case, the speed of the car is slower, and you can directly press the clutch. If the speed of the car is slow, such as 1 or 2 gears, there is no problem to brake directly by pressing the clutch.

3.In the third case, if it is only a slight deceleration, you can only need to collect one oil. There are other times, such as when you are approaching a traffic light.

The automatic transmission does not step on the clutch teeth; If the manual gear has its own repair function, it can also not be stepped on, so it is healthier to step on it at present!

First of all, we want to talk about the situation when you want to stop, not when you slow down. When it is fast, you often do not need to press the clutch when you press the brake, and you only need to press the clutch when it is very slow or when you need to stop it.

To understand the principle of brakes, the current car is basically a disc brake, through the brake pedal press, the caliper through the pressure of the brake oil to make the caliper piston act, the brake disc of the wheel bank to bite. This plays the role of braking the wheel hub and stops its vehicle. However, the whole braking process does not have any input to the engine and gearbox, that is, the engine and speedometer work as usual.

When the brakes are applied, there is a lot of confrontation (drag) with the engine and transmission. This usually results in engine stalling and damage to the engine and transmission. Therefore, when you apply the brakes, you should press the clutch to disconnect the power of the wheel hub from the engine power.

If you step on the brakes directly when parking, the transmission is still in the gear, and the engine is still transmitting power to the wheels if you don't step on the clutch, and the engine will be forced to shut down when the brakes are stepped on, which is not only unbearable for a long time.

When parking, step on the clutch first, which is equivalent to disconnecting the connection between the engine and the transmission device in advance, and the resistance of the brake at this time only acts on the wheels, so that the wheels stop rotating, and does not affect the operation of the engine, so it will not turn off;

If you don't step on the clutch, the wheels will be forced to stop turning, and at the same time the resistance will be transmitted to the engine through the transmission, and the engine will not be able to overcome such a large drag effect, it will stop working, that is, stall. Moreover, the car will also run away from one after another, the occupants are very uncomfortable, and the old stalling is also harmful to the engine.

When the speed is fast, you should step on the brakes first, if you step on the clutch first, it is equivalent to hanging neutral, which will make the car lose control, which is more dangerous. Wait for the speed to slow down, downshift, and then step on the clutch when you are almost at the parking point to prevent the car from stalling.

First, the reason why you can't directly step on the brakes

1. Because the function of the clutch is to control the output of engine power, it is necessary to cut off the engine power and let the engine idle before stepping on the brake, so that the car can stop smoothly without turning off.

2. If you do not step on the clutch and brake directly, the engine will protect itself and extinguish the fire.

Second, the working process and principle of the clutch

1. Work process. When the diaphragm spring is installed between the clutch cover and the pressure plate, the pressure on the pressure plate formed by the pre-compression deformation makes the main and driven parts of the clutch compressed, that is, the clutch is in the engaged state.

Engine power is transmitted to the disc via a flywheel, clutch cover and pressure plate connected to the crankshaft, and then to the input shaft of the transmission via the splined sleeve of the disc to the transmission. The working characteristics of this process are that the torque and speed transmitted by the main and driven parts of the clutch are the same, and there is no speed difference between the main and driven parts, and there is no slip grinding.

2. Separation process. The driver presses the clutch pedal, the pedal moves left, the push rod moves left, and the diaphragm spring separator moves left through the cylinder and the working cylinder. Affected by this, the diaphragm spring is fixed on the clutch cover with the support pin as the fulcrum, so that the big end moves to the right, and at the same time, the tension pressure plate moves right through the action of the separator plate.

Finally, there is a gap between the driven disc and the flywheel and the pressure plate, and the clutch is separated, and the clutch separation process is over.

The working characteristics of the clutch in the separation process are: the power and movement of the engine after separation cannot be transmitted to the driven disc. The active part remained in sync with the engine speed, while the driven part was rapidly reduced.

3. Joining process. The driver releases the clutch pedal, and the pedal returns to its original position under the action of the return spring, and at the same time drives the push rod and release bearing back into position. That is, the movement of the manipulating mechanism in the joining process is the reverse process of the separation process.

When there is a reserved gap between the release bearing and the diaphragm spring separating plate and the diaphragm spring re-compresses the pressure plate on the driven disc, the engagement process ends and the clutch resumes the function of transmitting power.

Clutch working principle] The clutch is composed of friction plates, spring plates, pressure plates and power take-off shafts, which are located between the engine and the gearbox, and are used to transmit the torque stored on the engine flywheel to the gearbox to ensure that the vehicle transmits the appropriate amount of driving force and torque to the driving wheels under different cavity driving conditions, which belongs to the category of powertrain. In the case of semi-linkage, the power input end of the clutch and the power output end are allowed to have a speed difference, that is, the appropriate amount of power is transmitted through its speed difference.

When running at low speed, you should press the clutch first, and when you are running at high speed, you should press the brake first.

1. Low-speed operation

When the car is running at low speed, such as the speed is 20-30km h and below, it is generally necessary to step on the clutch first, and then on the brake to prevent the engine from stalling.

2. High-speed operation

In high-speed operation, first lightly press the brakes, downshift, use the engine braking, and then step on the clutch after the speed is reduced to prevent stalling.

The flow of the brakes

1. Observe the traffic in front and the right lane, release the accelerator pedal, and turn on the right turn signal.

2. According to the distance of the parking target and bury the answer, properly step on the brake pedal of the liquid jujube under the Hui, and step on the clutch pedal when the speed is slow, so that the car can stop smoothly.

3. After the vehicle is stopped, tighten the parking brake lever and move the transmission lever to neutral.

4. Release the clutch pedal and brake pedal.

5. Turn off the turn signal, turn off the ignition switch as needed, and extinguish the engine.

Precautions

1. When the car is not stopped, the parking brake lever can not be pulled, and the car can not be turned off by lifting the clutch pedal by hanging gear.

2. According to the speed of the vehicle, the correct use of braking can be used to stop smoothly.

3. If the parking distance is close and the speed is fast, the brake pedal should be pressed heavier to reduce the speed quickly. When the car is about to stop, relax the brake pedal appropriately, and then increase the pressure a little to increase the braking force and stop smoothly.
