The invention discloses a coaxial chain wheel rail structure and relates to the field of rail transit and traction transmission. The device comprises wheels, rails, chain wheels on the outer sides ofthe wheels and tooth rails on the outer sides of the rails. The threads of the wheels are in contact with the rails, the chain wheels and the wheels are coaxially connected, needle bearings are arranged between the chain wheels and shafts and can be freely rotated, chain wheel tooth tips are evenly distributed on the edge of a gear, rail faces of the tooth rails are evenly provided with roller type toothed structures in the longitudinal direction, the chain wheels are engaged with the roller type toothed structures, steel columns are arranged on the side faces of the wheels, slot holes are formed in the chain wheels, the steel columns are inserted in the slot holes, the steel columns and the slot holes mutually act to prevent skidding of the wheels, and insufficient traction force or brakeforce is provided for a t
