The invention discloses a wet-type brake drive axle of a small-wheel-track forklift, which comprises a main speed reducer assembly, wherein the main speed reducer assembly adopts a contracted front suspension distance structure and is provided with a main speed reducer shell, a main transmission and differential assembly and an external hand brake assembly in a contracted integrated manner; wherein the main transmission and differential assembly adopts a contracted small-speed-ratio design structure; a built-in closed wet brake assembly which comprises a driving gear, a friction plate assembly, a piston assembly, a roller pin and a brake cylinder body which are arranged in an integrated manner; an axle housing assembly which is of a small wheel track design structure, a main speed reducermounting cavity is formed in the axle housing assembly, and the center of the main speed reducer mounting cavity deviates from the center line of the axle housing assembly and the axis of the axle housing; wherein the brake cylinder bodies are integrally arranged at the two ends of the axle housing assembly; and a secondary hub reduction mechanism. The size of the front suspension distance is effectively reduced, the size of the tooth bag wheel distance is reduced, and the drive axle is more compact.
