Problems solved by technology
[0004] In order to make up for the problems in the prior art, the object of the present invention is to provide a sub-frame structure, which solves the problem of deformation of the sub-frame after the mounting bolts are tightened due to machining accuracy, and fundamentally eliminates the problem caused by the sub-frame. The prestress problem caused by the deformation of the frame provides the reliability of the bolt connection

Abstract
The invention discloses a subframe structure. The subframe structure comprises a subframe body, wherein the subframe body is composed of circular steel pipes which are arranged at intervals, and reinforcing beams which are welded at intervals between the circular steel pipes; two ends of each circular steel pipe are upwards obliquely bent and extended; sleeves are arranged at the end parts of the circular steel pipes; clearance spacers are lengthways embedded and inserted in the sleeves; downward down-front control arm mounting brackets are mounted at the lower ends of the sidewalls of the bent extended parts at two ends of the circular steel pipe at the front side of the subframe body, and downward lower-back control arm mounting brackets are mounted on the circular steel pipe at the rear side of the subframe body; upward upper control arm mounting brackets are mounted on the reinforcing beams in the subframe body. The subframe structure is reasonable in structural design; the weight of the subframe is effectively reduced through a welding structure between the mounting brackets which are formed by sheet metal pressing and the tubular subframe body; the clearance spacer is adopted to remove clearances caused by processing precision or welding deformation, and therefore, the situation that the subframe is locally deformed or high prestress is generated due to excessively high bolt pre-tensioning force after the subframe is mounted can be avoided.
Description
technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an auxiliary frame structure. Background technique [0002] With the development of society, consumers have higher and higher requirements for automobile performance, and both reliability and handling stability have reached a new height. [0003] In order to meet the needs of consumers, automobile manufacturers have adopted independent front and rear suspensions for more and more models. Since most of the current cars use a one-piece body, in order to facilitate the installation of various connecting rods, a subframe structure for connecting rods must be designed. Four-point bolt connection is often used between the subframe and the longitudinal beam of the body. However, if the structural design is not good, or the processing accuracy is slightly deviated, or the subframe structure is deformed during the welding process, after the three points of the subframe are connec...
