How are the operating mechanisms of clutches classified?
2 Answers
The structure of a clutch consists of four parts: the driving part, the driven part, the pressing mechanism, and the operating mechanism. The following is an introduction to clutches: Function of a clutch: A clutch is similar to a switch, engaging or disengaging the power transmission. The driving part and the driven part of the clutch mechanism can be temporarily separated or gradually engaged, and they may also rotate relative to each other during transmission. There should be no rigid connection between the driving and driven parts of the clutch. Any type of vehicle has a clutch device, although the forms may vary. Classification of clutches: Clutches are divided into four types: electromagnetic clutches, magnetic particle clutches, friction clutches, and hydraulic clutches.
In my years of driving experience, clutch operating mechanisms are mainly classified into two types: mechanical and hydraulic. The mechanical type is the cable system commonly found in older cars—stepping on the pedal pulls the cable directly, which then disengages the clutch mechanism. The advantages are its simple structure and low cost, but over time, the cable tends to stretch or get stuck, requiring periodic tightening; otherwise, gear shifts feel stiff. The hydraulic type is more modern, using a master cylinder connected to the pedal to push hydraulic fluid to the slave cylinder, delivering smoother force transmission and reducing driver fatigue. The downside is that if the hydraulic line leaks or the fluid degrades, the clutch may fail. Modern models occasionally feature electronic systems controlled by sensors, but mechanical and hydraulic systems remain the mainstream in manual transmission cars. When classifying, focus on the core driving mechanism, and ensure smooth operation is key. It's recommended that owners regularly check and replace fluids or cables to avoid unexpected failures at high speeds.
