Reasons for Severe Shaking in First Gear Semi-Clutch Engagement
1 Answers
The severe shaking in first gear semi-clutch engagement can be attributed to three main reasons, as detailed below: 1. Uneven or deformed clutch disc, which requires thorough inspection; 2. Improper clutch adjustment—the clutch must be set at a moderate level, neither too high nor too low; 3. Issues with the universal joint bearing. Signs of problems include severe fatigue spalling, oxidation rust, wear pits, cracks, hardness dropping below HRC＜60, or excessive noise that cannot be adjusted, necessitating timely replacement. Additional Information: Friction clutches should meet the following basic requirements: 1. Ensure the transmission of the engine's maximum torque with some reserve capacity; 2. Achieve complete separation when disengaged and smooth engagement when engaged, with good heat dissipation capability; 3. Minimize the rotational inertia of the driven parts to facilitate speed changes in components connected to the transmission input shaft during gear shifts, thereby reducing gear impact; 4. Have the ability to mitigate rotational direction shocks and dampen vibrations in that direction, with low noise; 5. Maintain stable operation with minimal variation in pressure plate pressure and friction coefficient of the friction disc; 6. Be easy to operate and maintain.
