Classification of automotive clutches

Single disc dry clutch: This is the most common type in manual transmissions, which uses the friction between the friction plate and the pressure plate to transmit power. The advantages include simple structure, low manufacturing cost, high work efficiency, and easy maintenance. The disadvantage is that the service life is greatly affected by driving habits, and it is prone to heating and wear under high loads or frequent operation.

Multi plate clutch: composed of multiple sets of friction plates and steel plates stacked together, suitable for high-performance vehicles or motorcycles. The advantages are the ability to withstand greater torque transmission, smaller size, and ease of use in compact spaces. The disadvantage is that the structure is complex, the cost is high, and the heat dissipation performance is slightly worse than that of a single plate clutch.

Hydraulic torque converter: commonly used in automatic transmissions, transmitting power through the flow of fluid and the conversion of kinetic energy between turbines. The advantage is good smoothness, suitable for automatic transmissions, and high driving comfort. The disadvantage is low transmission efficiency and high maintenance costs.

Dual clutch: consists of two clutches, one controlling odd gears and the other controlling even gears, achieving fast shifting and improving the continuity of power transmission. The advantages are rapid gear shifting, short power interruption time, and improved fuel economy. The disadvantage is that the structure is complex, the maintenance and repair costs are high, and the performance may not be as smooth as traditional clutches at low speeds or frequent starts and stops.

Centrifugal clutch: Utilizing centrifugal force, it automatically engages when the engine speed reaches a certain level, suitable for light motorcycles or low-speed vehicles. The advantage is that it is easy to operate and suitable for lightweight design and low-speed scenarios. The disadvantage is that the power transmission efficiency is low and the control accuracy is not as good as manual or dual clutch.

Electromagnetic clutch: It controls the engagement or disengagement of friction plates by generating a magnetic field through an electromagnetic coil, mainly used in hybrid vehicles or special-purpose vehicles. The advantage is precise handling, suitable for vehicle systems with high levels of automation. The disadvantage is the need for stable power support and high manufacturing costs.

Wet clutch: Immersed in oil during operation, it has good cooling and lubrication effects.

These clutch types each have their own advantages and disadvantages, suitable for different vehicle types and usage scenarios, ensuring smooth operation and safety of the car under different working conditions.
