The automobile clutch is a key component in the automotive transmission system, whose main function is to establish or cut off the power transmission between the engine and the gearbox, ensuring smooth starting, smooth shifting, and stopping of the vehicle. On the basis of expounding the structure, principle, types, and maintenance of the clutch, this paper supplements the mechanical formulas related to clutch performance to quantitatively analyze its working characteristics, providing theoretical support for in-depth understanding of clutch design and optimization.
