The speed when fully releasing the clutch in first gear while practicing driving is within the range of 0-60 km/h. The first gear of a sedan can only operate within the range of 0-60 km/h, meaning that even if the accelerator is fully pressed, the speed will not exceed 60 km/h when driving in first gear. In contrast, the high-speed fifth gear can operate within the range of 65-170 km/h. When shifting up, the gear lever must be moved accurately and smoothly to avoid delaying the shifting opportunity. Manual transmission vehicle driving requirements stipulate: Clutch: It can be installed coaxially or on separate shafts, but the axial direction must be fixed. Neither the driving part nor the driven part is allowed to have axial movement. When installed on separate shafts, the coaxiality between the driving part and the driven part shaft should not exceed 0.1 mm. Engagement: Smooth and gentle to ensure a stable start of the vehicle; quick and thorough separation to facilitate gear shifting and engine starting; with appropriate reserve capacity to ensure the transmission of the engine's maximum torque while preventing overload of the transmission system. During driving: Frequent operation of the clutch can cause relative sliding between the driving and driven parts of the clutch, generating frictional heat. If the heat is not dissipated in time, it can severely affect the reliability and service life of the clutch.
