Is It Normal for a Motorcycle to Make a Clunking Sound When Shifting Gears?
1 Answers
It could be due to incomplete clutch disengagement or issues with the clutch or engine oil. Below is some expanded information about the clutch: 1. Functions: (1) Gradually increases the driving force of the vehicle, allowing for smooth starts; (2) Temporarily separates the engine and transmission for gear shifting; (3) Prevents overload in the transmission system; (4) Reduces torsional vibration impacts from the engine, extending the lifespan of transmission gears. 2. Structure: The friction clutch is the most widely used type, typically consisting of four parts: the driving section, driven section, pressing mechanism, and control mechanism. 3. Working Principle: It generally operates in two states: engaged and disengaged. The flywheel is fixed to the crankshaft, and the pressure plate is fixed to the flywheel, with the clutch disc sandwiched in between. Under normal conditions, the clutch disc is tightly pressed by the pressure plate, continuously transmitting power to the transmission when the engine is running (in neutral). When shifting gears, pressing the clutch pedal separates the pressure plate, cutting off power output.
