When a car is starting or shifting gears while driving, if the clutch is not fully disengaged and is in a state of being partially disengaged and partially engaged after depressing the clutch pedal, it can lead to difficulties in engaging (or shifting) gears, accompanied by gearbox gear clash sounds; or even the car starts or the engine stalls before the clutch pedal is lifted after shifting gears.

The vehicle starts with severe shaking, and its speed cannot be increased, acceleration is slow, it lacks power on uphill slopes, and its fuel consumption is high. The main reason is that the clutch's torque transmission capacity has decreased, and in severe cases, it cannot transmit torque. The cause of the fault is:

Check whether the clutch pedal, master cylinder, slave cylinder, release fork, release bearing, etc. are stuck or not moving flexibly, and whether the clutch pedal returns normally. If the problem persists after troubleshooting, proceed to the next step.

The function of the clutch system is to ensure smooth and reliable engagement between the engine and the transmission system, as well as to facilitate temporary yet complete disengagement. Engagement refers to the generation of friction torque, while disengagement refers to the removal of friction torque. Clutches operate frequently, and during vehicle operation, various components are prone to wear, deformation, or cracking due to sliding friction, which in turn reduces the friction torque and leads to clutch system malfunctions. Therefore, to maximize the service life of the clutch, it is crucial to properly and effectively maintain the clutch system. Common faults that occur during the use of the clutch include heavy pedal feel, slipping, incomplete disengagement (difficulty shifting gears), shaking, and abnormal noise.

During installation, the driven plate assembly must be positioned with the core shaft to ensure accurate installation and smooth sliding between the driven plate assembly and the transmission's first shaft;

The clutch is a key component of a car, which is related to whether the car can start and drive normally. Once a malfunction occurs, it can lead to a decrease in work ability or a deterioration in handling performance. In fact, in addition to inherent defects, a large part of clutch failures are caused by improper adjustment and maintenance. To facilitate readers' understanding of the causes of clutch failures, this article provides a brief introduction on how to maintain and repair these causes.
