Abstract
The invention discloses a front auxiliary frame cross reinforcement structure. The front auxiliary frame cross reinforcement structure comprises two front auxiliary frame longitudinal beams which are welded and fixed to two ends of two front auxiliary frame transverse beams, wherein the two front auxiliary frame transverse beams and the two front auxiliary frame longitudinal beams form a square framework; swinging arms are symmetrically hinged to and mounted on the opposite inner sides of the two front auxiliary frame longitudinal beams; the swinging arms are close to a junction point between the front auxiliary frame transverse beams on the rear sides and the two front auxiliary frame front auxiliary frame longitudinal beams; steering joints are fixed on the upper end surfaces of the swinging arms; X-shaped reinforcing plates are arranged under the two front auxiliary frame longitudinal beams; four ends of each reinforcing plate are fixed to two ends of the corresponding front auxiliary frame transverse beams. According to the front auxiliary frame cross reinforcement structure, an integrated cross reinforcement structure is mounted at four corners of a frame-shaped front auxiliary frame under the condition that arrangement of a power assembly is not influenced, so that the purpose of improving the overall rigidity and strength of the front auxiliary frame is achieved; the reduction of the risk of influence on the automotive performance caused because of insufficient rigidity or strength of the auxiliary frame can be facilitated; meanwhile, the smoothness of the automobiles can be improved.
Description
Technical field
The present invention relates to automobile manufacturing field, particularly relate to a kind of fore sub frame intersection and strengthen structure.
Background technology
The most McPherson suspension that adopts of automobile is as front suspension type, and McPherson suspension structure is simple, and quality is light, and what its subframe shape had is buttferfly-type, and what have is frame type.
Because McPherson suspension is straight barrel type, can bear larger vertical stressed, and the ability of resisting lateral impact is more weak, the anti-brake effect of nodding is poor, suspension stiffness is more weak, and cornering roll is obvious, for frame type subframe, first, need subframe have enough Rigidity and strengths to ensure automobile turn, braking time be unlikely to distortion excessive; Secondly, under jumping operating mode is hung down in single-wheel, subframe mainly bears flexion torsion load, and under larger moment of flexure or torsional interaction, subframe insufficient rigidity also can cause structure partial to destroy; Again, the subframe that rigidity is less can reduce the ride comfort of automobile in the process of moving.
Summary of the invention
The object of this invention is to provide a kind of fore sub frame intersection and strengthen structure, when not affecting dynamic assembly layout, improve fore sub frame integral rigidity and intensity, contribute to reducing subframe affects automotive performance risk because of rigidity or undercapacity, the ride comfort of automobile can be improved simultaneously.
Technical scheme of the present invention is as follows:
Fore sub frame intersects strengthens structure, comprise two front auxiliary car frame longitudinal beams being weldingly fixed on two fore sub frame crossbeam two ends, two fore sub frame crossbeams and two front auxiliary car frame longitudinal beams form square frame, the inwall that two front auxiliary car frame longitudinal beams are relative is symmetrical hinged is provided with swing arm, the chassis cross-member of swing arm near rear side and the interface point place of two front auxiliary car frame longitudinal beams, the upper surface of swing arm is fixed with steering swivel, it is characterized in that: the brace panel being provided with " X " type below two described fore sub frame crossbeams, four ends and corresponding every root fore sub frame crossbeam two ends of brace panel fix.
Described fore sub frame intersects strengthens structure, it is characterized in that: two described fore sub frame crossbeams are hollow rectangle beam, and two front auxiliary car frame longitudinal beams are hollow cylinder.
Described fore sub frame intersects strengthens structure, it is characterized in that: described brace panel width is 55 ~ 65mm, wall thickness 2 ~ 5mm.
Described fore sub frame intersects strengthens structure, it is characterized in that: stamp out two cross one another reinforced ribs in the middle part of described brace panel, brace panel edge is provided with stamping forming flange, flange and reinforced rib protrusion direction are in the same way, during installation, flange down, flange corner arc transition.
Advantage of the present invention is:
1. the brace panel of a decussate texture is installed at four angles of the fore sub frame in the present invention, add the integral rigidity of subframe, avoid because causing subframe to be out of shape the excessive strength problem brought under the operating modes such as turning, braking, and contribute to improving automobile ride;
2. the fore sub frame brace panel in the present invention, by reinforcement and flange design, improves support integral rigidity, substantially reduces the destruction of bringing due to flexing;
3. the difference that the fore sub frame brace panel structure in the present invention can be arranged according to vehicle type structure, changes brace panel panel beating thickness and cross sectional shape, and the position of hold-down bolt and specification also can depend on the circumstances simultaneously;
4. the fore sub frame brace panel structure in the present invention is simple, and improve fore sub frame stiffness obvious, cost is lower, and Assembly &Disassembly is convenient.

Fig. 2 is a brace panel wherein section drawing.
Detailed description of the invention
See accompanying drawing:
Fore sub frame intersects strengthens structure, comprise two front auxiliary car frame longitudinal beams 2 being weldingly fixed on two fore sub frame crossbeam 1 two ends, two fore sub frame crossbeams 1 and two front auxiliary car frame longitudinal beams 2 form square frame, the inwall that two front auxiliary car frame longitudinal beams 2 are relative is symmetrical hinged is provided with swing arm 3, the chassis cross-member 1 of swing arm 3 near rear side and the interface point place of two front auxiliary car frame longitudinal beams 2, the upper surface of swing arm 3 is fixed with steering swivel 4, the brace panel 5 of " X " type is provided with below two fore sub frame crossbeams 1, four ends and corresponding every root fore sub frame crossbeam two ends of brace panel 5 fix.
Two fore sub frame crossbeams 1 are hollow rectangle beam, and two front auxiliary car frame longitudinal beams 2 are hollow cylinder.
Brace panel 5 width is 55 ~ 65mm, wall thickness 2 ~ 5mm.
Two cross one another reinforced rib 5-1 are stamped out in the middle part of brace panel 5, to prevent brace panel from when subframe bends or reverse, flexing occurring, brace panel 5 edge is provided with stamping forming flange 5-2, flange 5-2 and reinforced rib 5-1 protrusion direction are in the same way, during installation, flange direction down, flange corner arc transition, reduces the impact of extending stress band.
The front suspension that the present invention matches is Mai Fuxun form, and its main body is frame type structure.Automobile easily causes the bending of fore sub frame or torsional deflection when turning, braking, the operating modes such as jumping of hanging down, the fore sub frame distortion that rigidity is less is excessive easily to be damaged, in order to increase bending, the torsional stiffness of fore sub frame, therefore structure of the present invention is adopted can to adapt to the demand of working environment completely, increase the service life, improve safety factor.
Four ends of brace panel 5 have a bolt hole, are connected with four hole bolts of the two fore sub frame beam-end in front and back.
Further, can according to actual conditions, change brace panel width, thickness and cross sectional shape, the position of hold-down bolt and specification also can depend on the circumstances simultaneously.The present invention can add the bending and torsion rigidity of subframe by actv., too increases transverse direction and the longitudinal rigidity of subframe simultaneously.
