Technical characteristics of the automatic transmission torque converter
Key Features:
*Torque: The ratio of output torque to input torque.
*Slip Ratio: The percentage difference between the speed of the input and output shafts.
* Efficiency: Power transmission efficiency.
Design:
* Pump impeller: Driven by the engine and creates a flow of oil.
* Turbine impeller: Connected to the output shaft and driven by oil flow.
* Reactor: Helps control oil flow and increase torque.
* Stator: The stationary part that directs the flow of oil.
Types:
* Three-element: Basic type with pump impeller, turbine impeller and reactor.
* Dual element: Does not have a reactor, which provides greater efficiency.
*Lock-up: Equipped with a lock-up clutch to improve efficiency at high speeds.
Locking characteristics:
* Actuation Speed: The speed at which the lock-up clutch engages.
* Actuation Pressure: Oil pressure required to engage the lockup clutch.
* Actuation Time: The time required for the lock-up clutch to engage.
Other characteristics:
*Oil Capacity: The amount of transmission fluid required for proper operation.
* Diameter: Diameter of the torque converter housing.
* Length: Length of the torque converter housing.
* Weight: Weight of the torque converter.
