Dana torque converter , such as torque multiplication and lock-up functionality. Torque converters tend to generate significant heat during operation.
Dana torque converter functionality
(1) Function of the clutch. When the engine is idling, the torque converter acts as a disengaged clutch between the engine and the transmission.
(2) Torque‑boosting effect. Under the combined conditions of “high pump impeller speed” and “low turbine speed,” the torque increases, resulting in greater start-up and driving torque.
(3) Hydraulic coupling. When not at idle or during startup, it functions as a hydraulic coupling, transmitting the engine’s torque to the transmission.
(4) Lock-up function. When the turbine speed rises to match the pump wheel speed, the lock-up clutch engages, and the torque converter transmits engine power to the transmission at a 1:1 ratio.
Dana torque converter Common causes of high fever due to overheating include:
(1) Use the torque converter in high gear.
(2) The oil temperature gauge is malfunctioning.
(3) Transmission oil level too low or too high.
(4) Engine overheating.
(5) The oil pump flow rate has decreased.
(6) The oil drain line is blocked.
(7) The connecting pipe of the oil cooler or cooler is blocked.
(8) Torque converter and transmission leaks.
(9) Oil degradation.
(10) Breathing hole blockage.
Dana torque converter Pressure is too high
The cause of excessive pressure is a clogged torque converter filter.
Dana torque converter The composition of
The torque converter consists of a turbine, a pump impeller, a stator, a lock-up clutch assembly, and a rear cover.
There is a sealed working chamber in which the fluid circulates. The pump impeller, turbine, and guide vane are respectively connected to the input shaft, the output shaft, and the housing. When the prime mover (such as an internal‑combustion engine or an electric motor) drives the input shaft to rotate, the fluid flows out of the centrifugal pump impeller, passes sequentially through the turbine and the guide vane, and then returns to the impeller, completing a continuous circulation. The pump impeller transfers the mechanical energy from the input shaft to the fluid.
High-speed fluid drives the turbine to rotate, transmitting energy to the output shaft. The hydraulic torque converter transmits torque by leveraging the interaction between the fluid and the blades to generate changes in angular momentum.
