Problems solved by technology

[0002] Since the position of the shift fork hole of the main reducer shell is far from the flange, and the wall thickness of the shell at its connection is thin, it cannot be fed by the riser during casting, and there are different degrees of shrinkage at the hot spot behind the shift fork hole. Holes, shrinkage and porosity affect product use

Abstract

The invention discloses a main reducer shell shifting fork hole structure and relates to the field of automobile manufacturing. The main reducer shell shifting fork hole structure comprises a main machine shell. The main body shell is provided with a first conformal cavity formed at one side of the shifting fork hole, and is also provided with a second conformal cavity located in the end portion of the shifting fork hole. The main reducer shell shifting fork hole structure is used for thinning a local structure, basic uniformity of wall thicknesses of a product is realized, and hot spots are eliminated, so that shrinkage defects of a position are eliminated, the product yield is improved, and loss caused by shrinkage and shrinkage porosity is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a shift fork hole structure of a final reducer housing. Background technique [0002] Since the position of the shift fork hole of the main reducer shell is far from the flange, and the wall thickness of the shell at its connection is thin, it cannot be fed by the riser during casting, and there are different degrees of shrinkage at the hot spot behind the shift fork hole. Pores and shrinkage will affect the use of the product. Contents of the invention [0003] The purpose of the present invention is to provide a shift fork hole structure of the main reducer housing, thin the local structure, realize the product wall thickness is basically uniform, eliminate thermal joints, thereby eliminate shrinkage cavity defects at this position, improve product yield, reduce shrinkage Losses caused by holes and shrinkage. [0004] In order to solve the probl...
