Abstract
The utility model discloses torsion-beam structures after a kind of automobile chassis, including crossbeam and stringer, the end of the crossbeam is weldingly connected with stringer, and the end of the crossbeam is equipped with bayonet arrangement, and stringer surface is equipped with positioning groove compatible with the bayonet arrangement of beam-end.Torsion-beam is reasonable in design after the automobile chassis, and crossbeam and stringer docking pass through the positioning groove on the bayonet and stringer of beam-end and cooperate positioning, and easy to operate, accurate positioning, welding deviation is small, and production efficiency and product quality greatly improved.
Description
Technical field
The utility model relates to vehicle chassis technology fields, more particularly, to torsion-beam structure after a kind of automobile chassis.
Background technique
The torsion-beam of automobile chassis includes connected crossbeam and stringer, and only the place of docking is weldingly connected with stringer for the end of crossbeam,
Connection reliability is poor；And beam-end and stringer are not easy wielding neck, and cooperation position can be produced because of frock clamp or artificial origin
Raw 3-6mm offset, will increase the fraction defective of lower process operations, not only increases production cost, can also reduce automobile four-wheel positioning
Stability.
Utility model content
In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide torsion-beams after a kind of automobile chassis
Structure, to achieve the purpose that weld easy to operate and accurate positioning.
In order to solve the above-mentioned technical problem, the technology employed by the present utility model is
Torsion-beam structure after the automobile chassis, including crossbeam and stringer, end and the stringer of the crossbeam are weldingly connected, described
The end of crossbeam is equipped with bayonet arrangement, and stringer surface is equipped with positioning groove compatible with the bayonet arrangement of beam-end.
Further, the bayonet of the crossbeam is stuck in the side and stringer top and the lower part of stringer of stringer.
The middle position of beam-end is arranged in the bayonet of the beam-end.
The bayonet arrangement of the beam-end includes upper snap-gauge and lower snap-gauge and the bayonet between upper and lower snap-gauge, is indulged
Beam is located between snap-gauge and lower snap-gauge.
The crossbeam is the hollow beam of lower openings, and lower snap-gauge is a pair being oppositely arranged.
The positioning groove is the side groove for being located at stringer side.
The utility model compared with prior art, has the advantage that
Torsion-beam is reasonable in design after the automobile chassis, and crossbeam and stringer docking pass through on the bayonet and stringer of beam-end
Positioning groove cooperate positioning, easy to operate, accurate positioning, welding deviation is small, and production efficiency and product quality greatly improved.

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 6, torsion-beam structure after the automobile chassis, including crossbeam 1 and stringer 2；The end of crossbeam 1 and vertical
Beam 2 is weldingly connected, and the end of crossbeam is equipped with 101 structure of bayonet, and stringer surface is equipped with mutually fits with the bayonet arrangement of beam-end
The positioning groove 201 matched.
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,
Accurate positioning, welding deviation is small, and production efficiency and product quality greatly improved.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the improvement for the various unsubstantialities that the conception and technical scheme for using the utility model carry out,
Or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
