Abstract

The invention provides a variable cross section plate spring assembly. The variable cross section plate spring assembly comprises a plate spring set. The plate spring set is formed in a manner that a plurality of single plate springs are assembled together through a certain prestress by means of a center bolt or a U-shaped bolt, the end portions of the single plate springs are additionally provided with damping rubber blocks, that is, the end portion of each plate spring is additionally provided with one elastic rubber block in a manner of through hole positioning, vulcanizing, cementing and the like, meanwhile, the end portions of the single plate springs are subjected to bending treatment, good attaching between the elastic rubber blocks and the plate spring end portion planes is guaranteed, the stress distribution among the springs is improved, the reliability of the plate spring assembly is improved, the appearance structure is simple, the installation manner of the variable cross section plate spring assembly and the installation manner of a current traditional plate spring are the same, and direct replacing can be achieved.

Description

technical field [0001] The invention relates to a series assembly of automobile leaf springs, in particular to a variable-section leaf spring assembly. Background technique [0002] Leaf spring is an important part of the vehicle suspension system. In the environment of energy saving and emission reduction, high-stress and lightweight leaf springs with small and variable cross-sections have been more and more widely used. The result is that several single pieces are assembled together by a central bolt or U-bolt through a certain pre-stress, and the ends of each piece are directly grounded, or the ends are installed with engineering plastic noise reduction pieces. Due to the deformation and vibration of the leaf spring during use, there is relative movement between the sheets, and the leaf springs that are in direct contact with the ends are prone to noise; the leaf spring assembly installed with engineering plastic noise-reducing sheets is also less effective in noise reduc...
