What Are the Functions and Roles of a Clutch?
1 Answers
The functions and roles of a clutch mainly include the following three aspects: 1. Gradually engage the engine with the transmission system to ensure smooth vehicle starting. When starting the car, the driver slowly releases the clutch pedal, allowing the driving and driven parts of the clutch to gradually engage. At the same time, the accelerator pedal is gradually pressed to increase the engine's output torque. This way, the engine's torque can be transmitted to the transmission system from small to large. When the traction force is sufficient to overcome the driving resistance during starting, the car begins to accelerate slowly from a standstill, achieving a smooth start. 2. Temporarily cut off the engine's power transmission to ensure smooth gear shifting in the transmission. During driving, due to changing driving conditions, it is necessary to constantly shift gears. For ordinary gear transmissions, different gear pairs need to disengage or engage during shifting. This requires pressing the clutch pedal before shifting to interrupt the engine's power transmission, making it easier to disengage the original gear pair and engage the new gear pair. 3. Limit the transmitted torque to prevent overload of the transmission system. During emergency braking, if the engine is rigidly connected to the transmission system, the engine speed will drop sharply, and all its components will generate a large inertial torque. This torque acting on the transmission system can cause overload and damage to the components. With a clutch, when the load on the transmission system exceeds the maximum torque the clutch can transmit, the clutch will eliminate this danger by slipping between the driving and driven parts, thus serving the purpose of overload protection.
