When do you need to step on the clutch? What is the purpose of stepping on the clutch?

As the transmission mechanism between the engine and the gearbox, the clutch is used to connect the power transmitted from the engine to the gearbox. When stepping on the clutch, the power is cut off and the car becomes a neutral sliding state; When the clutch is released, the power is reconnected, and the car can run forward again. when do you need to step on the clutch? When driving a manual transmission model, you need to step on the clutch when you start or change gears. First of all, let's talk about starting. Before the car starts, first step on the clutch pedal, separate the clutch, so that the engine and transmission system are disengaged, then put on the first gear, and then gradually loosen the clutch pedal, so that the clutch is gradually engaged. The purpose of this step is to make the power of the engine gradually transfer from the engine to the gearbox through the clutch, so in the initial stage, the speed of loosening the clutch should not be too fast, otherwise the power will be shut down by the engine itself before it is transferred to the gearbox. Loosening the clutch too quickly at the start is also a common mistake made by novices. The second is to step on the clutch when you are in gear. Because the clutch and gear are in an opposite relationship, you should step on the clutch when shifting gears, and when you don't need to shift gears, release the clutch and the car can run normally. Clutch is the medium of power transmission between engine and gearbox. When shifting gears, if there is no time gap to shift gears, there may be the risk of tooth-beating or even damage to the gearbox. Therefore, when shifting gears, you must step on the clutch and then shift gears. Finally, it is necessary to step on the clutch during emergency braking. When the car is braked urgently, if there is no clutch, it will bear great force inside the transmission system, which will damage the parts. With the clutch, you can rely on the friction plate inside the clutch to make the speed of the engine and gearbox form a difference to eliminate this danger.

What is the purpose of stepping on the clutch? The main purpose is to shift gears or keep the ride of power. In auto start, the driver slowly lifts the clutch pedal, so that the engine of the clutch is gradually engaged with the gearbox. At the same time, he gradually depresses the accelerator pedal to increase the output power of the engine, so that the power of the engine can be transmitted to the gearbox from small to large. Limit the torque transmitted by the engine to prevent the gearbox from being overloaded. When an automobile is in emergency braking, if the engine is rigidly connected with the transmission system, the engine speed will drop sharply, and the inertia generated will drag the parts in the transmission system, and this moment will be directly delivered to the internal parts of the transmission system, which will cause the transmission system to be unable to bear too much force and damage its parts.
