Why Is the Clutch of a Manual Transmission Car Stiff?
2 Answers
Manual transmission car clutch stiffness may be caused by clutch plate, clutch pressure plate, release bearing failure, or clutch master/slave cylinder malfunction. Clutch function: As the component directly connected to the engine in the automotive transmission system, it handles the engagement and disengagement of power and the transmission system. This ensures smooth vehicle starting, seamless gear shifting, and prevents transmission system overload. Friction clutch: Refers to a clutch that transmits torque through friction between driving and driven components. Widely used in modern vehicles. Hydraulic coupling: Refers to a clutch using fluid as transmission medium. Previously used in automatic transmissions, now rarely employed in automobiles. Electromagnetic clutch: Refers to a clutch operating through magnetic transmission, such as those used in air conditioning systems.
I remember when I first started driving, the clutch suddenly became stiff, feeling like stepping on a rock. Upon inspection, I found that the seals in the hydraulic system had aged, and the fluid had leaked out, causing the pump pressure to be too high. It could also be that the clutch cable was stuck with dirt and needed cleaning or lubrication. I didn’t pay much attention at the time, and shifting gears became extremely difficult, nearly causing an accident on the highway. Since then, I regularly check the clutch hydraulic fluid level and replace the fluid when necessary to prevent minor issues from becoming major problems. The mechanic said this is a common issue, and friends who often drive manual transmissions should also be careful.
