📌 torque converter:
A torque converter is a fluid matching device that transfers rotational energy from an internal combustion engine, such as an internal combustion engine, to a rotational-driven load, typically used in automated powertrains, marine propulsion systems, and industrial powertrains.
📌 Components
1.Propeller: Powered by internal combustion engine
2.Turbine: Load driven
3.stator: Insert between the propeller and turbine to change the oil flow
4. Clutch lock-up: Link physical propellers and turbines for efficient power transmission
📌 Working phase
1.standstill: the internal combustion engine supplies power, but the turbine cannot rotate.
2. Acceleration: The load accelerates. The speed of the turbine increases.
3.Connection: The turbine will reach 90% of the propeller speed.
📌 Working principle
The stator redirects the fluid flow from the turbine to assist the rotation of the propeller, causing the output torque to increase; as the speed of the turbine approaches the speed of the propeller, the stator clutch releases, allowing the stator to rotate with the propeller and turbine.
📌 Performance and torque multiplication
The torque converter cannot achieve 100% efficiency. The efficiency curve is similar to the XXXL, with zero efficiency at standstill, efficiency increased when accelerating, and low efficiency in the connection. Maximum torque occurs at standstill, with typical ratios ranging from 1.8: 1 to 2.5: 1.
📌 Type
1.Hydrodynamic: The most common type. Using fluid flow to transfer energy.
2.Hydrostatic: Use hydraulic pressure to transfer power
3.Mechanism: Use mechanical components to transfer power
📌 Usage
1.Automotive: Automatic powertrain
2.Marine: Propulsion system
3.Industry: Transmission system in conveyor belt drive, forklift, pulley and rig
📌 Modes of operation error
1.Overheating: Continuous slippage causes cooling to decrease
2.Stater clutch hold: inner and outer elements are permanently locked
3. Stater clutch rupture: Impact bearing causes fracture
4.Deformation and rupture of the blade: sudden weight bearing or excessive heat.
5.Inflation: Working for a long time under excessive load, distorting the converter frame.
📌 Innovation and future development
1.Dual-clutch powertrain: Improve gear shift speed and efficiency
2.Manual Automatic Transmission System: Combine the advantages of Manual and Automatic Transmission System
3. New power generation braking: Retain kinetic energy during braking
4. Advanced materials: Improve performance and durability.# Post a day
