The invention provides a new energy electric forklift axle reduction integrated floating type flexible connection drive axle structure which comprises a left shell and a right axle shell, a middle speed reduction shell is installed between the left shell and the right axle shell, and a motor horizontally arranged with the middle speed reduction shell is installed on the middle speed reduction shell. A small gear in butt joint with the output end of the motor is installed between the left shell body and the middle speed reduction shell body, a first duplicate gear meshed with the small gear is further installed between the left shell body and the middle speed reduction shell body, and a second duplicate gear and a differential mechanism assembly which are meshed with each other are installed between the middle speed reduction shell body and the right axle shell body. A left fan-shaped plate is integrally installed on the left shell, and a right fan-shaped plate is installed on the right axle shell in a floating type flexible connection mode. The structure adopts a three-stage helical gear speed reduction structure, has the characteristics of stable transmission and high transmission precision, is low in noise in the operation process, and is compact in spatial layout and beneficial to the layout of the whole vehicle because the motor and the axle housing are arranged in parallel.
