Independent suspension drive axle housing assembly for heavy-duty truck

Abstract

The invention provides an independent suspension drive axle housing assembly for a heavy-duty truck. The independent suspension drive axle housing assembly comprises an axle housing and a semi-axis arranged on the axle housing, wherein the upper end of the axle housing is fixedly connected with two symmetrical upper brackets; a frame mounting end face and a suspension upper swing arm mounting end face are formed on the upper brackets; the lower end of the axle housing is fixedly connected with two symmetrical lower brackets; a suspension lower swing arm mounting end face is formed on the lower brackets; the suspension upper swing arm mounting end face corresponds to the suspension lower swing arm mounting end face; a protective plate bracket is fixedly connected between the ends of the two lower brackets; the lower end face of the protective plate bracket is fixedly connected with a protective plate; and a main reducer mounting end face is formed on the axle housing above the protective plate. By adoption of the structural form, the frame, the suspension and the main reducer are connected with the axle housing through split connecting pieces, so that the casting process of the axle housing is simplified under the condition that the connection strength is guaranteed, and the manufacturing difficulty of the axle housing is reduced.

Description

Technical field [0001] The invention relates to a heavy vehicle, in particular to an independent suspension drive axle housing assembly of a heavy vehicle. Background technique [0002] At present, as independent suspension drive axles are increasingly widely used in the field of heavy vehicles, especially in the field of off-road vehicles, how to tap the maximum potential of independent suspension drive axles has become the focus of research. At present, the most widely used independent suspension drive axles are used to match independent suspensions. The middle section of the bridge, the main reducer and the differential are suspended on the frame by connecting with the axle housing, and the drive wheel parts on both sides of the suspension and the axle housing Connected, the driving wheels on both sides can swing up and down relative to the frame. However, most of the connecting parts of the above-mentioned bridge, the main reducer, the differential, and the axle housing are ...

AI Technical Summary

Problems solved by technology

However, most of the connection parts between the middle section of the above-mentioned axle, the main reducer and the differential gear and the axle housing are cast integrally with the axle housing, which makes the casting process of the axle housing more complicated and difficult to manufacture.
