Torque converter and oil pump connecting device for automatic transmission

摘要

The present invention relates to a torque converter and an oil pump connecting device for an automatic transmission, and an assembly structure for connecting the torque converter and an oil pump, wherein a spring cage into which a pump drive hub of the torque converter is inserted, and a pump drive hub by rotation of the pump drive hub and a plurality of sprags mounted on the spring cage to rub against the oil pump rotor, and since the pump drive hub and the oil pump rotor do not directly contact, damage to the pump drive hub and the oil pump rotor is prevented when the engine and transmission are engaged. It provides an assembly structure for connecting a torque converter and an oil pump connecting device for an automatic transmission, and a torque converter and an oil pump.
