Ступица крыльчатки гидротрансформатора Caterpillar 3989606

A Torque Converter Impeller Hub rotates at the same speed as the engine crankshaft, providing the initial rotational input to the torque converter. As the engine speed increases, the impeller hub's rotation speed also increases, generating a turbulent fluid flow within the torque converter. This fluid flow is what allows the torque converter to multiply the engine's torque before it is sent to the transmission.Attributes:• Provide better traction and control in low-speed and high-load situations• Absorb and dampen the impact of sudden torque changesApplications:A Torque Converter Impeller Hub transmits power and rotational motion from the engine to the torque converter. The impeller hub is connected to the engine crankshaft and is responsible for transferring the engine's rotational power to the torque converter.
