Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] see Figure 1-4 The shown intermediate support structure for the transmission shaft of an automobile includes a long support body 1, which is characterized in that: a left support bracket 2 is provided on the left part of the support body, and a right support bracket is provided on the right part The bracket 3, the left support bracket 2 and the right support bracket 3 have the same structure; a projection welding nut 4 is positioned and connected to the upper ends of the left support bracket and the right support bracket.

[0016] Furthermore, the cross-section of the support body is in an inverted "U" shape. Compared with the previous double-layer part cavity structure, it has the characteristics of simple structure, light weight, low cost and easy molding.

[0017] Further, the left support bracket and the right support bracket are box-shaped structures.

Abstract

The invention relates to a middle supporting structure of an automobile transmission shaft. The middle supporting structure comprises a strip-shaped supporting body and is characterized in that a left supporting bracket is arranged on the left portion of the supporting body, a right supporting bracket is arranged on the right portion of the supporting body, and the left supporting bracket and the right supporting bracket are the same in structure; the upper end of the left supporting bracket and the upper end of the right supporting bracket are respectively connected with a projection welding nut in a positioning mode. The middle supporting structure can effectively and reliably support the transmission shaft, guarantees stability and reliably of functions of the transmission shaft in a traveling process, and is simple in structure, low in weight, low in cost and easy to form.

Description

technical field [0001] The invention belongs to automobile body components, in particular to an intermediate support structure of an automobile transmission shaft. Background technique [0002] At present, front-end and rear-drive vehicles are becoming more and more common, and the supporting structures of the transmission shaft installed on the vehicle body are also in various forms. High, heavy, and complex in structure. In view of the deficiencies in the prior art, workers in this field have proposed a more reasonable structural design, such as "a transmission shaft support bracket" disclosed in CN201800544U, which includes a support bracket and an intermediate support, and the support bracket is connected to the frame beam , the intermediate support is arranged as a semicircular structure, and the intermediate support is connected with the support bracket. It has a simple structure, is easy to form, can obviously support the transmission shaft, saves materials, and i...
