Groined type upper plate and groined type lower plate fasten the subframe being formed by welding.
Background technique
Automobile rear sub-frame primarily serves supporting suspension system parts, transmits chassis stress, increases rigidity and control
Arm installation and motion profile guiding role.In order to meet the arrangement and performance of multi-link lever suspension fork, " well " font Rear secondary frame for vehicle is universal
It is used, i.e., comprising front beam, rear cross beam, left stringer, right vertical beam, and upper lower control arm mounting bracket is arranged in subframe
On " well " word beam, the installation point connecting with car body is arranged in the front and back quadrangle of " well " font beam.
Front beam, the rear cross beam of existing " well " font Rear secondary frame for vehicle, left stringer, right vertical beam generally use tubing welding or
After person's punching press sheet metal component is welded into front beam, rear cross beam, left stringer, right vertical beam, then group is welded into " well " font subframe frame.Such as
Front and back crossbeam, left-right longeron use pipe structure, and more uses cold stamping or interior high-pressure molding beam.And cold stamping shaped beam
Precision is compared with Customers ' Legal Right, and beam pipe and stringer pipe lap weld are short, and intensity is often weaker, needs to mend increasing reinforcer, and weight increase is led
Cause higher cost；Mold tooling higher cost needed for interior high-pressure molding beam.By punching press sheet metal component be welded into front beam, rear cross beam,
Group is welded into " well " font subframe frame again after left stringer, right vertical beam, and weld seam setting is more, and welding deformation is big, dimensional accuracy compared with
Customers ' Legal Right, welding procedure is complicated, and for weldquality compared with Customers ' Legal Right, frock cost is high." a kind of vapour as disclosed in CN 203623781U
Vehicle Rear secondary frame for vehicle ", it includes two stringers of front beam, rear cross beam and the forward and backward crossbeam of connection, and forward and backward crossbeam and stringer are through welding
It connects to form groined type, wherein front beam is the pipe fitting of hydro-forming, and the stamped molding of rear cross beam, rear cross beam cross sectional shape is U
Type is equipped with flange at U-shaped opening end.Its front beam is hydro-forming pipe fitting, and product fatigue life and stock utilization are high, product
Manufacturing cost is low；Rear cross beam cross section is U-shaped turnup structure, although part edge stress can be significantly improved, improves product fatigue
Intensity avoids leading to product failure because stress is caused to be concentrated for edge manufacturing defect；The structure design of stringer has taken into account vehicle row
The stability sailed, handling and collision energy-absorbing, can effectively protect occupant safety, improve the crashworthiness of vehicle, but still
Many deficiencies existing for existing " well " font Rear secondary frame for vehicle assembly are not solved.
Summary of the invention
The object of the present invention is to provide a kind of automobile rear sub-frames, can be improved integral strength and rigidity, welding deformation
Smaller, dimensional accuracy is higher；And stock utilization height can be improved, mitigate weight, reduces cost.
A kind of automobile rear sub-frame of the present invention, including Rear secondary frame for vehicle ontology, it is characterized in that:
The Rear secondary frame for vehicle ontology is by being in the upper plate of inverted " u " in " well " font and local section and being in " well " font and local section
It is fixedly connected with composition in the lower plate button merga pass weld seam of " U ", whole is in cavity body structure；The front of the cavity body structure is preceding cross
Beam, rear portion are rear cross beam, left part is left stringer, right part is right vertical beam；
Upper swing arm mounting bracket is respectively equipped in the upper surface of the front beam left part and right part；
Drag link mounting bracket is respectively equipped with below the front beam left part and right part；
Position to the left and middle part position to the right are equipped with lower swing arm mounting bracket separately below in the middle part of the rear cross beam.
Further, the casing of connection body is respectively provided in the four corners of the Rear secondary frame for vehicle ontology.
Further, it is equipped with upper overturning below in the upper plate, multiple overlap joint notches is set on the upper overturning, under described
The top of plate is equipped with lower flange, which is equipped with multiple boss, and multiple boss and multiple overlap joint notches are one by one
Corresponding matching constitutes multiple fastening structures.
Further, the upper plate and lower plate are molded by a monolith plate blanking punching.
Beneficial effects of the present invention:
(1) due to using molding " well " the font upper plate of integrated punching and lower plate welding fabrication, reduce fusion length, reduce
Welding deformation, dimensional accuracy are higher.
(2) since molding " well " the font upper plate of integrated punching and lower plate are buckled into " well " glyph framework, intensity is higher, weight
Amount is lighter, and cost is relatively low.
(3) self-positioning boss and lateral incision are fastened since molding " well " the font upper plate of integrated punching and lower plate are provided with,
Play the role of the limit of self-positioning and Z-direction, welding tooling, save the cost can not only be simplified；And welding deformation can also be reduced,
Promote Rear secondary frame for vehicle assembly precision.
(4) since " well " font upper plate and lower plate are by a monolith square plate blanking and punch forming, to improve material
Expect utilization rate, reduces costs.
