PURPOSE: A chain-driven differential drive axle is provided to properly regulate the rotating speed of right and left wheels according to each rotation radius during turning. CONSTITUTION: A center driving shaft(100) comprises a pair of first diameter portions(101) on both sides of a split flange and a pair of second diameter portions(103) on both sides of the first diameter portions. Driven sprockets(110,110') transfer power only in a specified direction and are installed on the first diameter portions to receive the torque of drive sprockets through a chain. A pair of hollow connection shafts(130) is partially overlapped in corresponding second diameter portions. A pair of ratchet bearings(150) is installed on the outer side of each hollow connection shaft to transfer power only in a specified direction. |
