Front sub-frame of minicar

Abstract

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.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to the structural improvement of the front auxiliary frame of miniature automobiles. Background technique [0002] At present, the front sub-frame of automobiles on the market usually adopts steel stamping welding combination or single-tube beam welding sub-frame structure. Due to the structural characteristics of this type of front sub-frame, in the actual production process, there are often the following two problems 1. There are many tooling fixtures and welding positioning fixtures, and the investment is large, so it is not suitable for small-scale production operations; 2. The labor intensity is high, there are many procedures, and the production cycle is long, which affects the overall work efficiency. Contents of the invention [0003] Aiming at the above problems, the present invention provides a front sub-frame of a miniature automobile with simple structure, good strength, eff...
