Abstract

A suspension beam assembly for a rear suspension comprises a suspension beam body and a first left connecting portion, a second left connecting portion, a second right connecting portion and a first right connecting portion which are sequentially connected along the bottom of the suspension beam body. The suspension beam body is formed by clamping a front floating beam plate and a rear floating beam plate of the same structure, a hydraulic lock is clamped to portion between the left and right ends of the front floating beam plate, a hydraulic lock is clamped to the portion between the left and right ends of the rear floating beam plate, inward concave lock grooves are formed in the portions, located above the suspension beam body, of the hydraulic locks, lock hooks are arranged inside the lock grooves, and the front and rear floating beam plates each comprise a left panel, a middle panel and a right panel which are sequentially connected, wherein the widths of the left and right panels are larger than the width of the middle panel, and an overlay plate, a constraint hole, a pipeline gap, an oval through hole or a height valve adjusting rod support are arranged on the suspension beam body. The suspension beam assembly is good in stability, the falling fixing accuracy of a cab can be ensured, the manufacturing and installation costs are low, and functionality is high.

Description

technical field [0001] The invention relates to a rear suspension equipment of an automobile, in particular to a suspension beam assembly for the rear suspension, which is particularly suitable for improving the accuracy of dropping and fixing the driver's cab.
