Description
Technical Field
The invention relates to the field of vehicle part manufacturing, in particular to a method for manufacturing a rear axle assembly with a torsion beam main beam and an upper plate side beam and a lower plate side beam, and a rear axle assembly with the torsion beam main beam connected with the upper plate side beam and the lower plate side beam.
Background
The automobile is one of the modern technology which is not separated by modern people, the transportation and road traffic are facilitated, the torsion beam type suspension in the chassis is one of the rear suspension types of the automobile, the up-and-down runout of the left and right wheels is balanced through a torsion beam, so that the vehicle is kept stable, although some manufacturers claim that the automobile is equipped with the torsion beam type semi-independent suspension, the torsion beam is one of the non-independent suspension type suspension, the torsion beam is provided with the independent torsion beam, the non-independent torsion beam and the semi-independent torsion beam, the semi-independent torsion beam is one of the torsion beam type semi-independent suspension, the balance bar is added on the torsion beam type non-independent suspension to enable the wheels to incline, the stability of the vehicle is kept, and the torsion beam type semi-independent rear suspension system is invented for the 70 th year of the 20, but the classical structure still has strong vitality until today, and is widely used in rear suspension systems of middle and small-sized families driven by front wheels. While in the development of the last 40 years, each car manufacturer has continuously upgraded and optimized torsion beam semi-independent suspensions, its main composition is still composed of 4 parts, torsion beams for bearing main vertical and lateral moments; longitudinal swing arms welded on the left side and the right side of the torsion beam; the elastic element and the connecting bracket are arranged at the front end of the longitudinal swing arm and used for connecting a vehicle body; spring damper system.
The torsion beam type semi-independent rear suspension system has the advantages of simple suspension structure and light weight; when the whole vehicle is assembled, the rear wheel is not required to be positioned, so that the assembly working hours are reduced; the occupied space is small, and a larger tail space is easy to obtain; the spring damper system facilitates a mating arrangement; the motion ratio of the wheel relative to the vibration reduction of the spring is controlled; the torsion beam characteristic can replace the function of a stabilizer bar; during the suspension movement process, the toe-in and track change is tiny; under the working condition of lateral force, the camber angle becomes smaller; the linear stability is good, and the rear tire loss is small; the brake nodding can be reduced by reasonably setting the characteristics of the elastic bushing.
Trailing arm torsion beam type non-upright suspensions are also known as "trailing arm type non-independent suspensions" by some manufacturers as "H-shaped longitudinal swing arm type suspensions". At present, the rear suspension of most class A and low-end SUV vehicle types in China generally adopts the suspension system with the structure, mainly because the suspension system occupies relatively small space of the vehicle body, has low manufacturing cost and can not cause the overall camber change of the vehicle body during movement. At the same time, the shock absorber does not bend under stress to increase the abrasion of the tire. Since the whole suspension system is composed of only one large component, the structure is much simpler than complex double fork arms, multiple connecting rods and the like. The suspension welded into the H shape is integrally arranged on the vehicle body, and the rocker arm and the vehicle body have only two connecting points, so that the assembly is simple, and the cost is low, which is required by the vehicle model of the level. In addition, the space occupied by the whole suspension is relatively small.
However, suspension systems of semi-freestanding construction also suffer from poor load carrying capacity, poor anti-roll capability, poor shock absorbing performance and limited comfort. The torsion beam generates torsion stress and shearing stress, and the welding joint has higher stress, so that the load born by the rear axle is allowed to be limited by the strength of the torsion beam; in order to ensure the running stability, the connecting points of the elastic bushings of the longitudinal swing arms on two sides are stressed in a complex manner; the wheels on two sides are mutually affected; poor comfort; the limit design is continuously carried out, various stresses caused by bearing are eliminated, and the stress is dispersed, so that the defect that we need to overcome all the time is overcome.
Disclosure of Invention
