Abstract

The invention discloses a vehicle frame with an optional back suspension, which comprises a first longitudinal beam, a second longitudinal beam, a first transverse beam, a second transverse beam, a third transverse beam, a fourth transverse beam, a fifth transverse beam, a sixth transverse beam, a seventh transverse beam and a back suspension mounting front bracket, wherein the seventh transversebeam positioned on the first longitudinal beam and the second longitudinal beam is provided with a plate spring rear bracket assembly; a helical spring upper tray assembly and a transverse stay bar bracket assembly are arranged between the plate spring rear bracket assembly and the back suspension mounting front bracket which is positioned on the first longitudinal beam and the second longitudinal beam; the transverse stay bar bracket assembly is fixed on the first longitudinal beam and the second longitudinal beam by welding or a bolt and is parallel to the seventh transverse beam; both the plate spring rear bracket assembly and the helical spring upper tray assembly are fixedly arranged at the lower parts of the first longitudinal beam and the second longitudinal beam by welding or bolts, and the plate spring rear bracket assembly comprises a sleeve and a sleeve mounting bracket. The vehicle frame in the structure can select back suspensions of different elastic elements without changing a vehicle frame body according to different requirements.

Description

technical field [0001] The invention relates to an automobile frame, in particular to an optional rear suspension frame. Background technique [0002] In automobile design, the non-independent suspension structure mainly has the following two forms: leaf spring non-independent suspension, which consists of leaf springs and shock absorbers; coil spring non-independent suspension, which consists of coil springs, shock absorbers , longitudinal thrust rod and lateral thrust rod. However, the structures and elastic elements of the two rear suspensions are non-replaceable. When the structure of the rear suspension is determined according to the function and road conditions, the above-mentioned vehicle frame structure cannot satisfy the requirements of the rear suspension with different elastic elements for the same vehicle frame. Suspension requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an optional rea...
