Auxiliary spring bracket

Abstract

The invention belongs to the technical field of the suspension system of the commercial vehicle, and particularly relates to an auxiliary spring bracket comprising a bracket installation part and a plate spring contact part. The plate spring contact part extends by being perpendicular to the side end face of the bracket installation part; the side end face of the bracket installation part is in the shape of a trapezoid; the bracket installation part and a frame are detachably connected; the plate spring contact part comprises an auxiliary plate spring connection part and a fender steel bar connection part, the cross section of the auxiliary plate spring connection part in the shape of an arc; the fender steel bar connection part is connected with the sunken side of the auxiliary plate spring connection part; the side wall, away from the auxiliary plate spring connection part, of the fender steel bar connection part is provided with a groove; the side walls of the groove are respectively provided with a first fin and a second fin; the first fin and the second fin are provided with through holes correspondingly; and the fender steel bar connection part is connected with a steel bar, so that the auxiliary plate spring connection part is connected with an auxiliary plate spring when the fender steel bar connection part is connected with the steel bar. According to the invention, the functions of the auxiliary spring bracket and a fender support are integrated as a whole, the structure is simple, and the weight is low.

Description

technical field [0001] The invention belongs to the technical field of commercial vehicle suspension systems, in particular to an auxiliary spring support. Background technique [0002] With the continuous development of society, commercial vehicles are used more and more widely in various business fields. Suspension system is an important shock-absorbing and load-bearing component of a commercial vehicle. How to balance comfort, load-bearing capacity and low cost while ensuring safety, so as to create higher profits, is a research direction for those skilled in the art. Among them, the rear suspension system in the form of main and auxiliary springs has a low manufacturing cost because of its strong bearing capacity. [0003] At present, the installation method of the rear suspension system in the form of main and auxiliary springs is simple. The main spring is mainly fixed by the front and rear roll lug seats. The main spring and the auxiliary spring are rigidly connected...
