Abstract

The invention discloses a light-weight assembly-type automobile twist beam suspension, relates to the technical field of automotive engineering, and solves the problems that the existing automobile twist beam suspension device has a complicated structure and larger mass, and the rigidity of a twist beam is inconveniently adjusted. The light-weight assembly-type automobile twist beam suspension comprises a variable cross-section V-shaped tubular twist beam, flange joints, suspension trailing arms, wheel connecting plates, shock absorber installation brackets, shock absorbers, spring seats and spiral springs. The left end and the right end of the variable cross-section V-shaped tubular twist beam are connected with the suspension trailing arms through the flange joints; one spring seat is welded on each suspension trailing arm; the spiral springs are arranged in the spring seats; one shock absorber installation bracket is arranged on each suspension trailing arm; the shock absorbers are arranged on the shock absorber installation brackets. According to the light-weight assembly-type automobile twist beam suspension, the variable cross-section V-shaped tubular twist beam can be manufactured from high-strength steel or aluminum alloy through a intra-high-pressure forming technology, and can also be manufactured from carbon fibers and resin adhesives in a hot pressing manner, so that the mass of the twist beam suspension is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering. It specifically relates to an automobile torsion beam suspension, in particular to an assembled automobile torsion beam suspension in which a V-shaped tubular torsion beam with a variable cross-section made of lightweight materials and techniques is connected to a suspension trailing arm through bolts. Background technique [0002] At present, the torsion beam semi-independent suspension is widely used in the rear suspension system of economical car chassis. It is favored because of its simple structure, low manufacturing cost, small space occupation of the body, and high cost performance. The existing automobile torsion beam suspension generally includes a coil spring, a shock absorber, and a torsion beam assembly composed of a trailing arm, a torsion beam, a spring seat and a shock absorber mounting bracket. As an important chassis component, the torsion beam assembly has a great i...
