Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As shown in Figures 1 to 8, the reliable and stable automobile torsion beam, including crossbeam 1 and stringer 2 and stiffening plate 3；Crossbeam 1
End is weldingly connected with stringer 2, and stiffening plate 3 is located inside hollow crossbeam, and the outer end of stiffening plate 3 is located at the lower section of stringer simultaneously
It is connected with the lower part of stringer.
The side of stiffening plate 3 and the inner wall of crossbeam are weldingly connected；It is affixed above the outer end of stiffening plate with the lower surface of stringer
It closes, the outer end of stiffening plate is connected with the lower weld of stringer.
The side of stiffening plate 3 is equipped with flange 301, and the inner wall of flange and crossbeam is weldingly connected.Stiffening plate is that outer imperial palace is small
The inner end middle part of plate structure, stiffening plate is equipped with open slot.
Stiffening plate 3 increases by two flange and passes through with flange position after beam engagement since angle is consistent with crossbeam angle
Within the controllable 1mm again of weld seam between the side and crossbeam inner wall of flange stiffening plate, it can satisfy robot welding, reduce
The cost of production increases the stability of weld strength.
Stiffening plate is located in the hollow structure of crossbeam, and stringer is located in stiffening plate, and the structure that can greatly improve junction is strong
Degree, it is firm to connect；And structure is simple, at low cost.
The end of crossbeam 1 is equipped with bayonet 101, and stringer is located in bayonet, and the bayonet edge and side rail inner of crossbeam weld
It is connected, stable structure is reliable.Stringer surface is equipped with positioning groove 201 compatible with the bayonet arrangement of beam-end, positioning
Easy to operate, fixed position is accurate, and deviation is small.
The middle position of beam-end is arranged in the bayonet of 1 end of crossbeam.The bayonet of crossbeam 1 is stuck in the side of stringer 2
With the lower part on stringer top and stringer.
The bayonet arrangement of 1 end of crossbeam includes upper snap-gauge 102 and lower snap-gauge 103 and the bayonet between upper and lower snap-gauge
101, stringer is located between snap-gauge and lower snap-gauge.Crossbeam is the hollow beam of lower openings, and lower snap-gauge is a pair being oppositely arranged,
Stable structure is reliable.
Stiffening plate 3 is equipped in 1 end of crossbeam, the outer end of stiffening plate is located at the lower section of stringer and the lower part phase with stringer
Even, the side of stiffening plate and the inner wall of crossbeam are weldingly connected, and overall structural strength can be improved.
Positioning groove 201 is the side groove for being located at stringer side, is not provided with positioning groove in stringer upper and lower part, positioning
Accurately, the structural strength of stringer is had no effect on.
According to the curve in beam engagement face, when increasing by two positioning grooves, stringer and beam engagement on stringer, because there is positioning
The fixation of groove increases the stability of welding position, improves qualification rate, reduce production cost, improves automobile four-wheel
The stability of positioning.
The positioning groove on bayonet and stringer that crossbeam and stringer docking pass through beam-end cooperates positioning, easy to operate,
