WING BODY STRUCTURE OF A WING BODY TRUCK FOR PREVENTING TWIST OF A WING-SHAFT BY INSERTING A METAL-RING IN THE MIDDLE OF THE WING-SHAFT, WELDING ONE SIDE OF THE METAL RING TO A WING, AND THEN WELDING A REINFORCING PLATE TO THE METAL RING

摘要

PURPOSE: A wing body structure of a wing body truck for preventing twist of a wing-shaft is provided to quickly transmit rotary power of a motor by combining directly a wing to a wing-shaft and to stably open and close the wing by equally dispersing load of the wing with a reinforcing plate. CONSTITUTION: In a wing body(100) comprising a wing body frame for supporting a wing and the wing combined to the wing body frame to open and close, a wing body structure of a wing body truck for preventing twist of a wing-shaft is composed of the wing-shaft installed rotatively to an upper wing body frame through a shaft-bracket; a metal-ring(140) inserted into the wing-shaft, wherein one end of the metal-ring is welded to the wing-shaft; a reinforcing plate(150) welded to the metal-ring; and the wing welded to the reinforcing plate.
