Description
Technical field
The utility model relates to automobile equipment device technique field, the semi-independent suspension of especially a kind of torsion girder-like.
Background technology
The semi-independent suspension of torsion girder-like is rear overhang hanging hang structure conventional at present, it by a torsion beam by the trailing arm of arranged on left and right sides by being welded together, the front end of trailing arm is connected with vehicle body by rear axle body support frame dress rubber-metal support, and the rear end of trailing arm is connected with damping spring with wheel hub, bumper.The trailing arm being connected with torsion beam can swing up and down around rigid connection point, by bumper and damping spring absorbing vibration, to play the effect of shock-absorbing; When both sides Suspension Deformation in operational process does not wait, torsion beam twists distortion, because torsion beam has larger elasticity, can play the effect of stabilizer antiroll bar.So critical component in the torsion beam semi-independent suspension that is torsion girder-like, it plays power transmission, the stressed effect with being connected balance both sides, and suspension is related to Vehicle handling and traveling comfort.
At present, V-shaped or " U " shape of the section of torsion beam, by being welded together between torsion beam and trailing arm, V-shaped or " U " shape of the section due to torsion beam, welding difficulty is large, technical requirements is high, solder design intensity is low; In the process of moving, may weld cracking be there is, cause automobile to occur some faults, the safety of impact driving.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly improves the semi-independent suspension of the torsion girder-like of Joint strenght between torsion beam and trailing arm.
The utility model solves the technical scheme that its technical matters adopts: the semi-independent suspension of torsion girder-like, comprise torsion beam, trailing arm, described trailing arm quantity is 2, the two ends, left and right of described torsion beam are connected to respectively by welding manner, V-shaped or " U " shape of the section of described torsion beam, described torsion beam and described trailing arm commissure are provided with brace panel, the overall arching bridge like of described brace panel, described brace panel reclines and is welded on described torsion beam medial surface and described trailing arm, and described brace panel is also provided with opening.
Further, the opening both sides of described brace panel are welded on the medial surface of described torsion beam respectively.
Further, the limit of described opening reinforces through flange process.
Further, also comprise torsion bar, described torsion bar is connected on described trailing arm through described opening.
The beneficial effects of the utility model are: the torsion beam of semi-independent for automobile torsion beam formula suspension and trailing arm commissure are provided with brace panel, the Joint strenght between increase, reduce the stress of commissure; Brace panel reclines and is welded on described torsion beam medial surface and described trailing arm, increases the area of contact of brace panel and torsion beam, improves Joint strenght further, reduces weld cracking risk, thus improves automobile handling stability, traveling comfort and safety.

Mark in figure: torsion beam 1, trailing arm 2, brace panel 3, opening 31, torsion bar 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the semi-independent suspension of torsion girder-like, comprise torsion beam 1, trailing arm 2, described trailing arm 2 quantity is 2, is connected to the two ends, left and right of described torsion beam 1 respectively by welding manner, V-shaped or " U " shape of the section of described torsion beam 1, described torsion beam 1 is provided with brace panel 3 with described trailing arm 2 commissure, such setting adds the Joint strenght between them, reduces the stress of commissure, described brace panel 3 recline be welded on described torsion beam 1 medial surface and described trailing arm 2 on.
Particularly, V-shaped or " U " shape of section due to described torsion beam 1, brace panel 3 is reclined and is welded on described torsion beam 1 medial surface, the area of contact increasing brace panel 3 and torsion beam 1 is set like this, further raising Joint strenght, reduces weld cracking risk, and brace panel 3 generally adopts block metal piece, the intensity of metal piece is high, and cost is low.
Particularly, as shown in Figure 1, the semi-independent suspension of torsion girder-like also comprises torsion bar 4, torsion bar 4 plays the effect connecting balance both sides, torsion bar 4 is arranged on the inner side of torsion beam 1, brace panel 3 is increased between torsion beam 1 and trailing arm 2, reduce the installing space of torsion bar 4, in order to not affect the installation of torsion bar 4, as shown in Figure 2 and Figure 3, by brace panel 3 whole installation arching bridge like be provided with opening 31 on brace panel 3, make torsion bar 4 can be connected with trailing arm 2 through opening 31 like this, thus the installation of torsion bar 4 can not be affected.Because brace panel 3 is provided with opening 31, so just become opening 31 both sides of brace panel 3 to be welded on the medial surface of described torsion beam 1 respectively.
In vehicle traveling process, the opening 31 of brace panel 3 frequently contacts with torsion bar 4, causes the wearing and tearing of brace panel 3, so the opening 31 of brace panel 3 is carried out flange consolidation process, strengthens the intensity at the edge of opening 31, improves the life-span of brace panel 3.
