Balance shaft support for heavy commercial vehicles

Abstract

The invention discloses a balance shaft support for heavy commercial vehicles. The top portion of the balance shaft support is provided with a top face, and the top face is provided with first connecting holes uniformly distributed in a line shape which are used for connecting a transverse beam of a car frame. the two sides of the bottom of the balance shaft support are provided with two lower pushing rod installation convex platforms, the two convex platforms are separately provided with third connecting holes for connecting lower pushing rods of middle and rear axles; two rectangular connecting faces provided with second connecting holes for connecting widths of longitudinal beams the car frame are extended upward on the upper portion of the balance shaft support, the convex portion of the lower portion of the balance shaft support is provided with fourth connecting holes for connecting connection plates beneath the balance shaft support, besides, the balance shaft support is provided with processing holes for processing. The balance shaft support for the heavy commercial vehicles effectively solves the problems of the decrease of system bearing capacity caused by the insufficient of bearing capacity of the connecting holes in the widths of the longitudinal beams and of the connecting holes of the transverse beams in the balance shaft support, at the same time solves the problem that the balance shaft support structure is heavy and the cost is high, thereby satisfying the light weight of the vehicle and the bearing capacity requirement.

Description

technical field [0001] The invention belongs to the technical field of automobile balance suspension and is suitable for heavy-duty commercial vehicles, and relates to a balance shaft support for heavy-duty commercial vehicles. Background technique [0002] The balance shaft bracket is the most important load-bearing part in the disconnected balance suspension. At present, it is divided according to the assembly form of the bracket and the shaft. There are mainly two structures: the split bracket shaft and the integrated bracket shaft. For the split structure of the support shaft, there are disadvantages such as heavy structure, long assembly time, and high cost. [0003] Patent Document 1 (CN205130848U) provides a heavy-duty vehicle balance shaft bracket and a heavy-duty vehicle using the balance shaft bracket, which can be applied to a lightweight disconnected rear balance suspension matching bimetallic composite bushings and a grease-lubricated structure. It can not only...
