The invention discloses a welded structure of a rear wheel hub assembly, a rear floor and a rear longitudinal beam of an automobile, the rear wheel hub assembly, the rear floor and the rear longitudinal beam are lapped and welded into a whole, and at the lapped and welded part of the rear wheel hub assembly, the rear floor and the rear longitudinal beam, the rear longitudinal beam is positioned between the rear floor and the rear wheel hub assembly and respectively welded with the rear floor and the rear wheel hub assembly, the rear floor is further welded with the rear wheel hub assembly, the rear floor is positioned on the inner side and the rear wheel hub assembly is positioned on the outer side. The welded structure can prevent water from flowing into the automobile from the lapped and the welded part of the rear wheel hub assembly, the rear floor and the rear longitudinal beam on the premise of maintaining current welding quality and coating and glue-squeezing speed.
Description
technical field [0001] The invention relates to the connection structure of auto parts, in particular to the welding structure between the rear wheel bulge of the automobile, the rear floor and the rear longitudinal beam. Background technique [0002] In the existing automobile structure, the rear wheel bulge is welded on the vehicle body as an independent part, and its main function is to isolate the rear wheel and the vehicle body, so as to prevent the water at the rear wheel from entering the vehicle during driving. [0003] The rear wheel bulge of the car is welded together with the rear floor and the rear longitudinal beam. Its lap welding structure is as follows: image 3 with Figure 4 As shown, the rear wheel bulge 1, the rear floor 2 and the rear longitudinal beam 3 are welded into one body by lap welding. At the overlapping welding of the three, the rear floor 2 is located between the rear wheel bulge 1 and the rear longitudinal beam 3, and The rear wheel bulge is...
