Abstract

The invention provides a nut fixing structure for an automobile subframe. The nut fixing structure comprises an automobile body, the automobile body is mounted and fixed through a subframe assemblingbolt, a bushing inner steel sleeve is arranged on the exterior of the subframe assembling bolt, bushing rubber is arranged on the exterior of the bushing inner steel sleeve, impact load is reduced through the bushing rubber, and a bushing outer steel sleeve is arranged on the exterior of the bushing rubber. Through the bushing rubber, fixing of a subframe is changed into flexible contact, abnormalsound of the subframe is avoided, the problem that the automobile subframe is prone to generating the abnormal sound during use is solved, as for flexible connection, the rubber bushing is pressed into the subframe, thus the impact load transmitted to the automobile body from the road surface is reduced, and thus riding comfortableness is improved.

Description

technical field [0001] The invention relates to the field of automobile subframe manufacturing, in particular to a nut fixing structure for the automobile subframe. Background technique [0002] Nowadays, when manufacturing automobiles, it is very common to use automobile subframes as vehicle load-bearing components. At present, bolts are generally used to fix the sub-frame, but since the bolts are rigidly fixed, that is, the bolts are in direct contact with the iron parts, it is easy to produce abnormal noise during work, which affects the sense of use. Therefore, it is particularly important to solve the problem that the sub-frame of the automobile is prone to abnormal noise during use. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a nut fixing structure for the sub-frame of an automobile, which changes the sub-frame into flexible contact through the bushing rubber, avoids the abnormal noise of...
