What is the function of an automobile crankshaft?
1 Answers
The function of an automobile crankshaft is to convert the thrust transmitted by the piston connecting rod into rotational torque, transforming the reciprocating linear motion of the piston into the circular rotational motion of the crankshaft. It then delivers the engine torque to the transmission system via the flywheel, while also driving the engine's valve train and other auxiliary devices. The crankshaft is the most critical component in an engine. During engine operation, the piston is propelled by the combustion of the compressed air-fuel mixture, causing linear motion, which is then transmitted to the crankshaft via the connecting rod. The crankshaft converts this linear motion into rotational motion. The rotation of the crankshaft serves as the power source for the engine and the primary driving force for the entire mechanical system.
