Ensure that the car starts smoothly: Before the car starts, the engine must be started first. When a car starts, it gradually accelerates from a completely stationary state. If the transmission system is rigidly connected to the engine, the car will suddenly rush forward as soon as the transmission is put into gear, but it will not start. With the clutch, after the engine is started, the driver can first depress the clutch pedal to disengage the clutch, then shift the transmission into gear, and then gradually release the clutch pedal to gradually engage the clutch, thereby achieving a smooth start. Convenient gear shifting: During the driving process of the car, in order to adapt to the changing driving conditions, the transmission system often needs to change to different gears. Before shifting gears, the clutch pedal must be depressed to interrupt the power transmission so that the meshing pair of the original gear can be disengaged. At the same time, the speed of the meshing parts of the meshing pair of the new gear can gradually be synchronized, so that the impact when entering the mesh can be greatly reduced. reduced, resulting in smooth shifting.
