Torque converter automatic transmission Ford Explorer
The torque converter is an important component of the Ford Explorer automatic transmission. It transmits torque from the engine to the transmission and serves as a clutch.
Design and operating principle
The torque converter consists of three main elements:
* Pump wheel: Connects to the engine crankshaft and transmits the movement of fluid.
* Turbine Wheel: Connected to the transmission input shaft and rotated by fluid.
* Stator: A fixed element located between the pump and turbine wheels. It directs the flow of fluid, increasing torque.
When the engine is running, the pump wheel spins a fluid known as transmission fluid (ATF). The fluid hits the turbine wheel, causing it to rotate. The stator redirects the fluid flow, creating additional torque, which is transmitted to the transmission input shaft.
As vehicle speed increases, the slip ratio between the pump and turbine wheels decreases, resulting in a more direct gear ratio.
Functions
The torque converter performs several important functions in an automatic transmission:
* Torque Transmission: Transfers torque from the engine to the transmission.
* Torque Multiplier: Increases torque at low speeds for smooth acceleration.
* Vibration Damping: Absorbs engine and transmission vibrations for smooth shifting.
* Clutch: Serves as a clutch, facilitating gear changes and preventing torque from being transferred to the transmission when the engine is running.
Malfunctions
A faulty torque converter can lead to automatic transmission problems, including:
*Slippage
* Vibrations
* Jerks and jolts when changing gears
If you notice such symptoms, it is recommended that you contact a mechanic for diagnosis and repair.
Service
To maintain the performance of the torque converter and the automatic transmission as a whole, it is necessary to follow a regular maintenance schedule. This includes:
* Replacement of transmission fluid and filter.
* Checking fluid level and condition.
* Diagnose the torque converter for signs of wear or damage.
