Description
Technical field
The utility model relates to the trailing arm on the vehicle Wrest bar type back axle, especially a kind of variable section vehicle trailing arm member.
Background technology
Car beam trailing arm be used for connecting bushing, turn round the important foundation member that members such as beam, Shock absorber and wheel hub stay bearing plate constitute vehicle rear axles.
The vehicle trailing arm generally adopts hollow circular-tube or hollow square tube to make; Its axis shows as C type or S type on front view, on lateral plan, be generally straight line, and its sleeve end oblately is connected with axle sleeve through striking out; Hub end is connected with the wheel hub adapter plate, and the back of a bow of intermediate projections is connected with torsion beam.The wheel hub adapter plate is used for the installation of vehicle hub, and the form of wheel hub adapter plate determines by the version of trailing arm, so the version of trailing arm member has very big influence for the carrying and the endurance quality of vehicle rear axle assembly.
The stand under load situation of vehicle hub is complicated, the support stiffness and the intensity of wheel hub adapter plate is had very high requirement, for connection rigidity and the support strength that improves wheel hub adapter plate and trailing arm; Reduce relative disturbance and the durability and the integrity problem that cause of vehicle hub between adapter plate various load-up conditions under and trailing arm, being connected between wheel hub adapter plate and the trailing arm generally needs to adopt and assist gusset improve rigidity of support and intensity; When adopting the uniform cross section hollow circular-tube to make; It is curved that auxiliary gusset and wheel hub adapter plate form the angle, and when adopting the hollow square tube of uniform cross section to make, auxiliary gusset and wheel hub adapter plate form a right angle U type; Auxiliary gusset directly is welded on the outside tube wall of hollow pipe fitting of S type; With regard to mechanical property, under the long-pending situation of same cross-sectional, the load-carrying properties of hollow square tube are lower than hollow circular-tube; Therefore, also adopt at present mode with the involutory welding of big or small slice to improve the load-carrying properties of hollow square tube member.
Adopt the trailing arm molding component process of hollow square tube of uniform cross section or hollow circular-tube simple, but have following weak point:
1. the later welded complex process of member and wheel hub adapter plate;
2. though the wheel hub adapter plate adopts auxiliary gusset to carry out bracing reinforcement, the weld seam increase can make the reliability decrease of back axle assembly;
3. adopt right angle U-shaped wheel hub adapter plate directly to be welded on the tube wall of the hollow square tube of the S type outside, can improve the connective stability of wheel hub adapter plate, but the carrying mode of hollow square tube is relatively poor relatively;
4. the involutory welding manner of employing big or small slice can improve the load-carrying capacity of hollow square tube in theory, but to structure manufacture and complicated more with the technology controlling and process of wheel hub adapter plate welding.
Along with developing rapidly and the technological development of lightweight of auto manufacturing; In recent years; The version of variable section trailing arm member proposes; Its axis shows as C type or S type on front view, on lateral plan, be generally straight line, and for example number of patent application is the utility application of 200680004327.X.The defective of its existence: the carrying mode of the complex structure of wheel hub adapter plate, trailing arm structure is relatively poor, the influence of weld seam is big, material consumption is bigger.
The forming process more complicated of non-uniform member generally has two kinds of manufacturing process at present, when adopting traditional process to make, generally needs half sheet of first punching press more than 2 or 2, is welded into integral body again.Need multi-step process, work step is many and be difficult to satisfy the coherence request of member.A kind of in addition is to adopt the method for making of hollow circular-tube through internal high pressure forming; Its basic craft course is to wait diameter pipes to make blank; Apply superhigh pressure liquid through tubing inside; And in course of exerting pressure, pass through the material of member along axis direction replenished, making pipe is required workpiece at the mold cavity internal shaping.Comparatively speaking, internal high pressure forming only needs bending, internal high pressure forming and end cut three process, need not later welded, and have certain advance, but adopt the technology controlling and process of internal high pressure forming complicated,, reality has on using than limitations.
