What is a Torque Converter Composed Of?
2 Answers
A torque converter is composed of a pump impeller, turbine, and stator. It is installed between the engine and transmission, using hydraulic oil as the working medium to perform functions such as torque transmission, torque conversion, speed change, and clutch engagement. The working principle of a torque converter is as follows: the pump impeller is driven by the engine to rotate, pushing the fluid to rotate around its axis along with the pump impeller, thereby acquiring a certain speed and pressure. The characteristics of a torque converter include: 1. Depending on the machine's driving resistance or operational resistance, the torque converter can automatically and continuously vary speed and torque within a certain range; 2. It extends the service life of the machine; 3. It improves the machine's passing performance and comfort.
I've always found torque converters quite fascinating, especially the smooth driving experience they provide in automatic transmission vehicles. It's primarily encased in a sturdy housing containing three core components: the impeller connects directly to the engine shaft, and when the engine rotates, its blades propel the transmission fluid; the turbine links to the transmission shaft, where fluid flow impacts its blades to drive the output; the stator is fixed between them to help increase torque output. Special hydraulic fluid flows throughout, ensuring smoother power transfer. I've seen older vehicles without lock-up clutches in their torque converters, which consumed more fuel at high speeds, but modern cars incorporate this feature to directly connect and save fuel once speed stabilizes. Maintenance involves regular checks of fluid color and level to prevent contaminant buildup. Overall, this component makes driving feel effortless, reducing jerky movements and being particularly beginner-friendly.
