A torque converter and clutch automatic transmission is a type of automatic transmission that combines both a torque converter and a clutch to transfer power from the engine to the transmission.
Components and operation:
* Torque converter: A device that converts mechanical energy from the engine into hydraulic energy and vice versa.
* Clutch: A multi-plate or cone device that mechanically connects or disconnects the engine and transmission.
*Planetary Gear: A set of gears that provide different gear ratios.
*Hydraulic valve: Controls the flow of fluid through the torque converter and clutch.
Working principle:
When the engine starts, the clutch is open and the torque converter is filled with fluid. The fluid transfers energy from a pump driven by the engine to a turbine connected to the transmission. This allows the engine to operate at a lower speed than the transmission output shaft, providing smooth acceleration from a standstill.
As the car picks up speed, the clutch gradually closes, transferring some of the power mechanically through the clutch. This helps improve efficiency and reduce power loss associated with the torque converter.
When the car reaches a certain speed, the clutch is fully closed and power transfer is completely mechanical through the clutch.
Advantages:
* Smooth gear shifts
*High fuel efficiency
*Ease of use
* Capable of transmitting high torque
*Easy to maintain
Flaws:
*May be less efficient than other types of automatic transmission at high speeds
*Additional production and service costs
