Problems solved by technology

Cylinder block + frame structure, the mass of the cylinder block assembly is heavy, the frame looks simple, but the actual casting is complicated, the scrap rate is high, and the processing technology is complicated
Cylinder block + main bearing cap structure, the quality of the cylinder block assembly has declined. However, for the inline four-cylinder or six-cylinder cylinder block, the assembly efficiency of the main bearing cap is low and requires too much manpower. , during the assembly process, there is a high risk of scrapping the cylinder block due to the main bearing cap

Embodiment Construction

[0016] like Figure 4 As shown, the conjoined main bearing cover 4 is located below the upper cylinder block 1, the outer frame body 7 is located outside the conjoined main bearing cover 4, and the upper cylinder block, the conjoined main bearing cover and the outer frame are connected and fixed to each other. Among them, the upper cylinder block is made of die-cast aluminum alloy material; the conjoined main bearing cover is made of gray iron material; the outer frame body is made of die-cast aluminum alloy material, and the upper cylinder block and the outer frame body are made of lighter materials , which can effectively reduce the weight of the engine cylinder block.

[0017] like figure 1 , figure 2 As shown, the upper cylinder block and the conjoined main bearing cover are respectively provided with mounting bolt holes 2 and 6, and the upper cylinder block and the conjoined main bearing cover are connected and fixed by bolts through the aforementioned mounting bolt ho...

Abstract

The invention relates to an automobile engine cylinder body, which can effectively simplify processing technology and improve assembly efficiency. The invention adopts the technical proposal that the automobile engine cylinder body is characterized in that the cylinder body is provided with an upper cylinder body, a connected main bearing cap and an outer frame body, wherein the connected main bearing cap is positioned under the upper cylinder body; the outer frame body is positioned outside the connected main bearing cap; and the upper cylinder body, the connected main bearing cap and the outer frame body are connected and fixed with one another.

Description

technical field [0001] The invention relates to an automobile engine cylinder block. Background technique [0002] At present, the automobile cylinder block assembly structure mainly includes two forms: cylinder block + frame and cylinder block + main bearing cap. Cylinder block + frame structure, the weight of the cylinder block assembly is heavy, the frame seems simple, the actual casting is complex, the rejection rate is high, and the processing technology is complex. With the structure of cylinder block + main bearing cap, the quality of the cylinder block assembly is reduced. However, for the inline four-cylinder or six-cylinder cylinder block, the assembly efficiency of the main bearing cap is low and requires too much manpower. , During the assembly process, the risk of the cylinder block being scrapped due to the main bearing cap is very high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an automobile engine cylinder block,...
