Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the semi-independent suspension of this utility model torsion girder-like, including torsion beam 1, trailing arm 2, tire support 3, hub
Installing plate 4, trailing arm 2, tire support 3, hub installing plate 4 quantity is two, two trailing arms 2 be connected to torsion beam 1 a left side,
Right two ends, each trailing arm 2 are provided with a tire support 3, each tire support 3 are provided with a hub installing plate 4,
Being provided with welding hole 41 on each hub installing plate 4, each hub installing plate 4 is fixed on tire support 3 by welding hole 41, and uses
The mode of welding is plug welding.Plug welding improves the bonding strength of hub installing plate 4 and tire support 3, is effectively reduced running car
During at this weld seam stress concentrate, reduce the risk of weld cracking, thus improve automobile handling stability, comfortableness and peace
Quan Xing.
In order to improve the weld strength of hub installing plate 4 and tire support 3, and ensure the intensity of hub installing plate 4 self, pass through
Lot of experiments and practice draw, as in figure 2 it is shown, be provided with two welding holes 41 on each hub installing plate 4, two welding holes 41 points
Not being positioned at the both sides that hub installing plate 4 is relative, such setting both can guarantee that raising weld strength, does not interferes with hub installing plate 4 simultaneously
The intensity of self.Further, welding hole 41 is bar hole, and bar hole two ends are circular arc.Bar hole increases the area of weld seam,
Convenient operation, reduces distorting stress simultaneously and concentrates in commissure.
The mode that torsion beam 1 is connected with trailing arm 2 is welding, in order to reduce answering at torsion beam 1 and trailing arm 2 attachment weld
Power, reduces weld cracking risk, simultaneously in order to improve automobile handling stability, comfortableness and safety.Torsion beam 1 is set to upwards
The circular arc arcuation of bending, thus reaching one is in the case of being increased without suspension rate, increases the torsional rigidity of suspension；Two are
By the weld stress of trailing arm 2 and torsion beam 1 to torsion beam intermediate transition, reduce commissure, both sides stress, reduce weld cracking wind
Danger.Further, this utility model is provided with torsion bar 6 in torsion beam 1, and torsion bar two ends are corresponding with torsion beam 1 two ends respectively
Trailing arm 2 by welding by the way of connect, by arranging torsion bar 6, can in the case of the vertical stiffness not increasing suspension, increase
The roll stiffness of suspension and roll angular rigidity, both ensure that the stationarity of automobile turning, in turn ensure that the comfortableness of car load.In order to
Improve torsion beam 1 two ends and the bonding strength of corresponding trailing arm 2 further, add as it is shown on figure 3, this utility model is provided with two
Strong plate 5, torsion beam 1 and trailing arm 2 commissure be provided with a reinforcing plate 5, and reinforcing plate 5 reclines and is welded on torsion beam 1 medial surface
With on trailing arm 2, reinforcing plate 5 typically uses the metalwork of bulk, and the intensity of metalwork is high, low cost.Due in torsion beam 1 with vertical
Increase reinforcing plate 5 between arm 2, reduce the installing space of torsion bar 6, in order to not affect the installation of torsion bar 6, reinforcing plate 5 is overall
It is arranged to arch bridge shape and in reinforcing plate 5, is provided with opening 51, so making torsion bar 6 can be connected with trailing arm 2 through opening 51, from
Without affecting the installation of torsion bar 5.
