The torque converter in a Toyota automatic transmission (automatic transmission) is a hydraulic device that performs the following functions:
Power transmission from engine to automatic transmission:
* The torque converter connects the engine and automatic transmission, providing torque transmission.
Torque Conversion:
* It acts as a clutch to increase torque at low speed, which is essential for smooth starting and acceleration of the vehicle.
* As speed increases, torque gradually decreases to ensure efficient engine control.
Preventing engine stalling:
* When the vehicle is at rest or at low speed, the torque converter allows the engine to continue running even if the vehicle is not moving.
* This prevents engine stalling and makes the car stop and start smoother.
Softening jerks and shocks:
* The torque converter absorbs shock loads when changing gears, providing smooth shifting and reducing wear on automatic transmission components.
Toyota torque converter design:
The Toyota automatic transmission torque converter usually consists of the following components:
* Pump: Driven by a motor and pressurizing the fluid.
* Turbine: Connected to the output shaft of the automatic transmission and receives torque from the pump.
* Reactor: Located between the pump and turbine and helps control fluid flow, improving torque conversion.
*Lockup: A clutch that locks the torque converter at higher speeds to improve engine efficiency and reduce fuel consumption.
Torque converters are an important component of Toyota automatic transmissions, providing smooth and efficient control of the engine and transmission.
