Why does the car still shake when slowly releasing the clutch?
2 Answers
The reasons for car shaking when slowly releasing the clutch: uneven pressure distribution of the car clutch, incorrect pressure position; or excessive elasticity of the clutch pressure spring; oil contamination or breakage of the driven plate lining; bending of the main and driven plates, inconsistent height of the release levers. Extended information is as follows: Clutch: Installed between the engine and the transmission, it is the assembly component in the car's drivetrain that directly connects with the engine. Usually, the clutch is installed together with the engine crankshaft's flywheel group and serves as the component that cuts off and transmits power between the engine and the car's drivetrain. Throughout the process from starting the car to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the drivetrain, cutting off or transmitting the power output from the engine to the drivetrain. Its function is to allow gradual engagement between the engine and the transmission, ensuring smooth car starting; temporarily cutting off the connection between the engine and the transmission to facilitate gear shifting and reduce impact during shifting; and providing separation during emergency braking to prevent overload of the transmission and other drivetrain components, thereby offering a certain protective effect.
The car still shakes when slowly releasing the clutch, and I've been pondering this issue for quite some time. The most common reasons are worn clutch discs or an uneven flywheel surface. Over time, clutch discs wear unevenly, causing unstable power transmission; if the flywheel is warped or scratched, the vibration is stronger during engagement. It could also be insufficient pressure from the pressure plate springs, leading to rough engagement. Another possibility is aging or loose engine mounts or transmission support bushings, causing resonance. Additionally, improper driving habits, such as poor throttle-clutch coordination when releasing the clutch, with engine RPM too low or too high, can easily cause shaking. It's recommended to inspect clutch component wear—if severe, replace them. During normal starts, coordinate the throttle and clutch operation, and practice smooth takeoffs. Regular maintenance can prevent these issues, making driving smoother. I've seen many friends overlook these, only to spend more time and money on repairs later.
