Abstract

The invention provides a driving gear hollow mechanism. The driving gear hollow mechanism comprises a driving gear and a gear shaft. The driving gear is connected to one end of the gear shaft. A through hollow structure is arranged in the middle of the driving gear and extends along the middle of the gear shaft to the position close to the other end of the gear shaft. According to the driving gear hollow mechanism, the hollow structure is adopted in the middle, and the weight and material cost of a component can be greatly lowered; furthermore, the weight of an assembly is lowered; and fuel oil economical efficiency of a finished automobile is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a hollow mechanism for driving gears. Background technique [0002] In the field of automobiles, as the governments of various countries have increasingly stringent requirements on environmental protection, the requirements on fuel economy of automobiles are also getting higher and higher. Following this, lightweight design has become the focus of various automobile companies to develop new models. [0003] At present, the manufacturing technology of key parts used for drive axle parts needs to be broken through urgently, especially the key parts need to be innovated urgently in terms of weight reduction. [0004] In particular, in recent years, great progress has been made in the hollow forging technology in China, especially the progress of the hollow rolling forming process, which provides a technical basis for the lightweight design of forgings. [0005] In the prior art, the prob...
