In an automatic transmission, the torque converter serves a crucial function as a fluid coupling between the engine and the transmission. It allows the engine to continue running even when the vehicle is stationary and provides several important benefits to the overall operation of the transmission system.
The primary function of a torque converter is to transmit engine torque to the transmission and subsequently to the wheels. It accomplishes this through a complex hydraulic system that utilizes transmission fluid to transfer power. The torque converter consists of three main components: the impeller, turbine, and stator.
1. Impeller: The impeller is connected to the engine crankshaft and is responsible for driving the transmission fluid. As the engine rotates, it causes the impeller to spin, creating a flow of transmission fluid.
2. Turbine: The turbine is connected to the input shaft of the transmission and is driven by the flow of transmission fluid from the impeller. As the fl....
