The present invention relates to a power transmission coupling installed inside a speed reducer, which comprises a fluid coupling for transmitting the power of an engine driving axis to a speed reducer axis through the circulation of inner oil; and a lockup clutch for directly connecting the engine driving axis and the speed reducer axis. The fluid coupling comprises a starting pump connected to the engine driving axis; a passive unit connected to the speed reducer axis to transmit the driving power of the starting pump to the speed reducer axis; and a flywheel plate which has a certain diameter and rotates with the starting pump. The lockup clutch is connected to the speed reducer axis, where a pressure plate is pressed to the flywheel plate by an oil pressure at a certain velocity ratio to connect the engine driving axis with the speed reducer axis. As an integrated fluid coupling and a lockup clutch are installed in the speed reducer, which configures a compact power transmission structure of the engine driving axis, and the speed reducer axis is configured. |
