The invention relates to a front sub-frame of a minicar, and provides a front sub-frame for the minicar, which is simple in structure and high in strength, and through the adoption of the front sub-frame, the number of tooling fixtures can be effectively reduced, the capital investment can be reduced, and the labor intensity can be reduced. The front sub-frame takes the shape of a framework, and comprises a pair of front stringers, a pair of front brackets, a pair of rear brackets, a pair of front swing arm brackets, a beam and a steering gear bracket, wherein the steering gear bracket comprises a fixing rod and a pair of connecting rods; the connecting rods are separately arranged at two ends of the fixing rod, and are separately arranged on the front stringers; abdicating grooves are separately formed in each of the connecting rods, and each of the connecting rods is provided with a supporting segment; a plurality of reinforcing blocks are also arranged on the front stringers; each of the reinforcing blocks comprises a reinforcing medium plate and a pair of reinforcing side plates, wherein the reinforcing medium plate is triangular; each of the reinforcing side plates comprises a reference column and a supporting extension plate which are integrally connected; a plurality of positioning holes are formed in each of the front stringers. According to the front sub-frame disclosed by the invention, the tooling fixtures are reduced, the investment cost is reduced, the labor intensity is reduced, and the structure strength is improved.
