Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0025] like figure 1 and figure 2 As shown, the rear axle frame for passenger cars in this embodiment includes a suspension system installation assembly, a beam assembly 1 and two sets of longitudinal beam assemblies 2 . Among them, the beam assembly 1 and the longitudinal beam assembly 2 are arranged in a criss-cross pattern; the beam assembly 1 includes a middle beam 11 and a side beam 12, the middle beam 11 is arranged between adjacent longitudinal beam assemblies 2, and the side beam 12 is arranged between the longitudinal beam assembly 2 and the side beam 12. Between the side walls of the passenger car. In this embodiment, the suspension system installation assembly includes four groups of airbag installation parts 3, and each group of airbag installatio...

Abstract

The invention provides a rear axle frame for buses. The rear axle frame includes a suspension system installation assembly, crossbeam assemblies and two sets of longitudinal beam assemblies; the crossbeam assemblies and the longitudinal beam assemblies are in vertically and horizontally staggered arrangement; the crossbeam assemblies include middle crossbeams arranged between the adjacent longitudinal beam assemblies and side crossbeams arranged between the longitudinal beam assemblies and the side wall of a bus; the suspension system installation assembly includes four sets of airbag installation parts; each set of the airbag installation parts is installed between the side crossbeams and the longitudinal beam assemblies; and two sets of the airbag installation parts and the other two sets of the airbag installation parts are in symmetric arrangement along the center line of the longitudinal beam assemblies. The rear axle frame has advantages of being high in operation safety and reliability, reasonable in layout and convenient in assembly.

Description

technical field [0001] The invention relates to the field of new energy passenger cars, in particular to a rear axle frame for passenger cars. Background technique [0002] At present, the chassis frame of new energy buses is generally a full load-bearing structure. The full load frame includes the front suspension section frame, the front axle section frame, the middle section frame, the rear axle section frame and the rear section frame. The layout of the existing rear axle frame is poor in rationality, which makes the suspension system mounting bracket and other components of the rear axle frame prone to stress concentration and excessive weight of the suspension system mounting bracket during the operation of the passenger car, resulting in easy There are problems such as cracking, low safety and reliability of passenger car operation, inconvenient assembly of suspension system mounting brackets, and poor aesthetics. Contents of the invention [0003] The technical p...
