Abstract
The utility model relates to a novel automobile transverse beam and longitudinal beam lap joint structure, which is used for connecting an automobile transverse beam and a longitudinal beam. The lap joint structure comprises a reinforcing plate, wherien one end of the reinforcing plate is connected with the automobile transverse beam, the other end of the reinforcing plate is connected with the automobile longitudinal beam, and a flange is respectively arranged on the reinforcing plate at the connecting parts with the transverse beam and the longitudinal beam. When the structure is adopted, the longitudinal beam and the transverse beam are covered by one complete reinforcing plate, no punching opening exists, the stress concentration is reduced, and the lap joint intensity is greatly improved. In addition, flanges do not need to be processed at both ends of the transverse beam, the processing work procedures are reduced, and the punching defects are avoided.
Description
Technical field
The utility model belongs to the technical field of automobile construction, and specifically, the utility model relates to a kind of new automobile crossbeam and longeron bridging arrangement.
Background technology
The Modern Car overwhelming majority adopts monocoque skin construction, be characterized in that vehicle body does not have vehicle frame, but the rigid frame structure that skeleton, floor and roof etc. are welded, whole bodywork component all participates in carrying, and body framwork is mainly formed by crossbeam and longeron overlap joint.For self-supporting body, all external loads all need be born by the body framwork member common the distribution, so the height of body in white rigidity directly influences the quality of car load endurance quality, and the rigidity of body in white is directly relevant with the intensity of body framwork crossbeam and longeron lap-joint, we can say that the structure of lap-joint directly influences the torsional stiffness and the bending stiffness of body in white, thereby influence the endurance quality of car load.
At present on the motorcar body, the overlap joint of crossbeam and longeron mainly is by designing flange at the crossbeam two ends, then with spot welding with flange and longeron weld together, two kinds of connection structures as depicted in figs. 1 and 2.Adopt this connection structure, the every end of crossbeam all has turnup structure, and punch forming complexity and flange indentation, there are easy to generate stamping defect.In car load road examination process, when vehicle body generation integral body under the turning or the operating mode of jolting was reversed or is crooked, the indentation, there of crossbeam and longeron overlap joint was easy to generate stress concentration, thereby produces cracking phenomena simultaneously.
The utility model content
Technical problem to be solved in the utility model provides a kind of new automobile crossbeam and longeron bridging arrangement, eliminates the stress concentration of vehicle beam and longeron junction, strengthens the Joint strenght of vehicle beam and longeron.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of new automobile crossbeam and longeron bridging arrangement, be used to connect vehicle beam and longeron, and this bridging arrangement comprises a brace panel, this brace panel one end is connected with described crossbeam, and the other end is connected with described longeron.
On described brace panel, be equipped with flange with the junction of described crossbeam and longeron respectively.
On described brace panel, be provided with groove.
Described brace panel and described crossbeam and longeron are and are welded to connect.
The utility model vehicle beam and longeron bridging arrangement overlap automobile longitudinal girder and crossbeam by adopting a brace panel, have following advantage:
(1) longeron and crossbeam are wrapped with a complete brace panel, do not had punched openings, reduced stress concentration, greatly improved bond strength;
(2) the crossbeam two ends need not process flange, have reduced manufacturing procedure, have avoided stamping defect.
Description of drawings
Fig. 1 is the vehicle beam that relates in this specification sheets background technology and the structural representation of longeron bridging arrangement;
Fig. 2 is the vehicle beam that relates in this specification sheets background technology structural representation with longeron another kind bridging arrangement;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the enlarged diagram of brace panel in the utility model;
Mark among the above-mentioned figure is: 1, crossbeam; 2, longeron; 3, brace panel; 4, flange; 5, groove.
The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the present utility model is described in further detail by description to embodiment.
As shown in Figure 3, Figure 4, a kind of new automobile crossbeam of the utility model and longeron bridging arrangement, be used to connect vehicle beam 1 and longeron 2, this bridging arrangement comprises a brace panel 3, these brace panel 3 one ends are connected with vehicle beam 1, the other end is connected with automobile longitudinal girder 2, and brace panel 3 is with vehicle beam 1 and longeron 2 and is welded to connect, and is equipped with flange 4 with the junction of crossbeam 1 and longeron 2 respectively on brace panel 3.Adopt this kind structure, longeron 2 and complete brace panel 3 of crossbeam 1 usefulness are wrapped, do not have punched openings, reduced stress concentration, greatly improved bond strength; And crossbeam 1 two ends need not process flange, have reduced manufacturing procedure, have avoided stamping defect.
Also be provided with groove 5 on brace panel 3, when crossbeam 1 was connected with brace panel 3, crossbeam 1 stretched in this groove 5.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
