When to press the clutch? When to step on the clutch

1. Ensure a smooth start of the car.

This is the primary function of the clutch. Before the car starts, it is natural to start the engine first. Whereas, when the car starts, the car accelerates gradually from a completely stationary state.

If the drivetrain (which links the entire car) is rigidly connected to the engine, the car will suddenly rush forward as soon as the transmission is engaged, but it will not start. This is because when the car moves from standstill to forward, it generates a large inertial force, which causes a large drag torque to the engine. Under the action of this inertial drag torque, the engine speed drops sharply to below the minimum stable speed (generally 300-500rpm) in an instantaneous time, and the engine is turned off and cannot work, and of course, the car cannot start.

That's why we need the help of the clutch. After the engine starts, before the car starts, the driver first presses the clutch pedal, disengages the clutch, disengages the engine and the drive train, and then puts the transmission into gear, and then gradually releases the clutch pedal to make the clutch gradually engaged. In the process of engagement, the drag torque of the engine gradually increases, so the accelerator pedal should be gradually pressed at the same time, that is, the fuel supply to the engine should be gradually increased, so that the speed of the engine is always maintained at the lowest stable speed without stalling.

At the same time, because the tightness of the clutch gradually increases, the torque transmitted by the engine to the driving wheel through the drive train gradually increases, and when the traction force is enough to overcome the starting resistance, the car starts to move from standstill and gradually accelerates 2, ensuring that the drive train works smoothly when shifting.

2: Achieve smooth shifting.

In the process of driving, in order to adapt to the changing driving conditions, the drive train often has to change different gears to work. To realize the gear shift of the gear transmission, it is generally to toggle the gear or other gear mechanism, so that a gear pair of the original gear is pushed out of the transmission, and then the gear pair of another gear is put into the work. Before shifting gears, the clutch pedal must be stepped on, and the power transmission is interrupted, so that the meshing pair of the original gear can be disengaged, and the speed of the meshing part of the new gear meshing pair is gradually synchronized, so that the impact when entering the meshing can be greatly reduced, and a smooth shift can be realized.

3. Prevent overload of the drive train.

When the car is braking urgently, if there is no clutch, the engine will be rigidly connected with the drive train and reduce the speed sharply, so all the moving parts will produce a large moment of inertia (its value may greatly exceed the maximum torque emitted by the engine when working normally), causing more than its bearing capacity to the drive train, and causing damage to the parts. With a clutch, it is possible to rely on the relative movement that may occur between the active and driven parts of the clutch to eliminate this danger. Therefore, we need a clutch to limit the maximum torque that the drivetrain can withstand and ensure safety.

Clutches can be divided into: friction clutches, or the use of liquid as the transmission medium (i.e., fluid couplings), or the use of magnetic transmission (i.e., electromagnetic clutches).

Step on when changing gears, in order not to damage the engine.

Step on it when you are stuck in traffic, so as not to make the car catch fire.

When you are stuck in a traffic jam, you are afraid of stepping on the fire.

When the dial on the right side of the car rotates more than 2,000 rpm, you can change gears.

Press the clutch when starting the vehicle, and press the clutch when changing gears, and it is easy to hit the gearbox gear if you don't step on it. Hit the brakes until the speed drops to 20 hours to prevent stalling.

The clutch is located in the flywheel housing between the engine and transmission. The clutch assembly is screwed to the rear plane of the flywheel, and the output shaft of the clutch is the input shaft of the gearbox. When the car is moving, the driver can press or release the clutch pedal as needed, so that the engine and transmission are temporarily separated and gradually engaged, so as to cut off or transmit the power input from the engine to the transmission destroyer.

1.When stepping on the clutch, try to use the front foot to pedal, so that you can step hard, step steadily, and step thoroughly. Remember not to press the clutch with the ball of your foot or instep, as this will make you feel bad. When stepping on the clutch, the heel should touch the ground, but the front foot should move up and down back and forth.

2.When you're ready to start or shift, press the lower clutch quickly, not too slowly or intermittently. This requires you to react quickly when you press the clutch and to pedal it without hesitation. When stepping on the clutch, keep your feet away from the accelerator and do not step on the accelerator.

3.When stepping on the clutch, remember to press it to the end, otherwise it will accelerate the wear and tear of the clutch, and it will be difficult to change gears after a long time, which is very important for developing good driving habits.

4.After stepping on the clutch, after a quick shift or a successful start, slowly lift the clutch, especially when changing 2nd and 3rd gears, especially slowly, otherwise the car will make abnormal noises. While slowly lifting the clutch, gently press the accelerator with your right foot.

The clutch is used for starting, shifting, braking and stopping. When the car clutch starts, it can completely separate the transmission system and the power system, so that the car can start smoothly without turning off.

In the initial phase, the clutch should not be released too quickly, otherwise the engine will suffocate the power itself before it is transmitted to the gearbox.

Loosening the clutch too quickly at the start is also a common mistake made by novices.

When in gear, step on the clutch scramble.

Because the clutch and gear are in an opposing relationship, so when changing gears, you have to step on the clutch, and when you don't need to change gears, release the clutch and the car can drive normally.

The clutch is used as a medium between the engine and the transmission power transmission, when changing gears, if there is no time gap to change gears, then there is a risk of teeth or even damage in the gearbox.

Therefore, when changing gears, be sure to press the clutch and then shift gears.

Press the clutch during emergency braking.

When the car is braking urgently, if there is no clutch, it will bear a lot of force on the inside of the transmission system, and the parts will be damaged.

With a clutch, it is possible to rely on the friction plates inside the clutch to create a difference between the engine and transmission speeds to eliminate this danger.

When do you need to step on the clutch? The clutch needs to be pressed before starting, and the clutch needs to be pressed before shifting gears and stopping, which is the primary function of the clutch. The timing of the need to step away from the front combiner:

1. Before the car starts, first press the clutch pedal, separate the clutch, disconnect the engine and the transmission system, and then hang up the first gear, and then gradually release the clutch pedal to gradually engage the clutch; 2. When braking, the clutch should be stepped on, when the car is braking, if there is no clutch balance, the load will exceed its bearing capacity to the drive train, and the parts will be damaged; 3. The clutch should be stepped on when adding and decreasing gears, in the process of driving, in order to adapt to the changing driving conditions, the drive train often has to change different gears to work, and the clutch pedal must be stepped on before shifting the sail to interrupt the power transmission, so that the impact when entering the meshing can be greatly reduced to achieve smooth gear shifting; 4. Reduce the speed of the vehicle to step on the clutch before parking, and when the vehicle slows down less than 20 kilometers, you can step on the clutch to stop, because it is already a safe speed. @2019
