Torque Plate
Torque plates connect the torque converter housing to the engine
flexplate in automatic transmissions, transferring rotational power
while enabling fluid coupling between engine and transmission.
Grey Iron Torque Plates for Automatic Transmission Systems
Torque plates are cast components inside automatic transmission torque converters. They bolt to the engine's flexplate and drive the converter housing, which contains the fluid coupling that transfers power to the transmission input shaft. As the engine rotates, the torque plate spins the converter housing, setting the transmission fluid in motion. This fluid then drives the turbine connected to the transmission, allowing smooth power delivery without a mechanical clutch.
The torque plate experiences constant rotation and load variations as vehicles accelerate, decelerate, and shift gears. We manufacture these components from grey iron grades selected for dimensional stability and fatigue resistance under cyclic loading. The casting process establishes wall thickness, bolt hole locations, and overall geometry that must be accurate for proper balance and alignment within the torque converter assembly. After casting, machining operations bring mounting surfaces, bolt patterns, and balance features to the tight tolerances required. Each plate undergoes dimensional inspection and material verification to ensure it meets torque converter assembly specifications for automotive and industrial transmission applications.
