Abstract
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
The present invention relates to the connection structure of auto parts and components, particularly the welded structure between automobile back wheel bulge and floor, back and the floor side member.
Background technology
In the existing vehicle structure, the trailing wheel bulge as one independently parts be welded on the vehicle body, it mainly acts on is to isolate trailing wheel and car body, avoids in the vehicle traveling process, the water at trailing wheel place into the car.
The trailing wheel bulge of automobile is that overlap joint is integrally welded with floor, back and floor side member; Its overlap joint welded structure such as Fig. 3 and shown in Figure 4; Trailing wheel bulge 1, floor 2, back and floor side member 3 threes overlap integrally welded, and at three's overlap joint weld, back floor 2 is between trailing wheel bulge 1 and floor side member 3; And the trailing wheel bulge is positioned at the inboard, and floor side member 3 is positioned at the outside.This overlap joint welded structure requires in the car production process; Welding and coating process must reach qualification rate very; Otherwise water will be according to direction shown in dotted arrow among Fig. 4, along the trailing wheel bulge, from the slit of trailing wheel bulge and back floor lap-joint into the car.In order to guarantee water not into the car from this overlap joint weld, just need in process of production to improve welding quality, promptly increase the number of solder joint, improve the position of weld accuracy, and reduce the speed of application plastic squeeze, and will cause the reduction of production efficiency like this.
Summary of the invention
The welded structure that the purpose of this invention is to provide a kind of automobile back wheel bulge and floor, back and floor side member; Under the prerequisite of keeping existing welding quality and application plastic squeeze speed, can avoid water to flow in the car from the overlap joint weld of trailing wheel bulge, floor, back and floor side member.
The welded structure of automobile back wheel bulge according to the invention and floor, back and floor side member comprises trailing wheel bulge, floor, back and floor side member, and the three overlaps integrally welded; Overlap joint weld at trailing wheel bulge, floor, back and floor side member; Floor side member is between floor, back and trailing wheel bulge, and with floor, back and trailing wheel bulge welding, also weld with the trailing wheel bulge on back floor respectively; Back floor is positioned at the inboard, and the trailing wheel bulge is positioned at the outside.
After adopting overlap joint welded structure according to the invention; The water at trailing wheel place is at the overlap joint weld that under the lateral of trailing wheel bulge, flow to rear drum bag and floor side member under the effect of self gravitation; And then under the lateral of floor side member, flow to ground; Because water can not get in the tie welding seam of trailing wheel bulge and floor side member under the self gravitation effect from bottom to top; So even the sealing of the overlap joint weld of trailing wheel bulge and floor side member not exclusively, water can not flow in the car from the overlap joint weld of trailing wheel bulge and longeron yet.In addition, though the water that in the vehicle ' process, splashes up from the overlap joint weld percolation mistake of trailing wheel bulge and floor side member, the overlap joint weld of back floor and trailing wheel bulge is the inflow of block water once more also.So welded structure according to the invention has good sealing property; Under the prerequisite of keeping existing welding quality and application plastic squeeze speed; Effectively block water flows in the car from the overlap joint weld of trailing wheel bulge, back floor and floor side member, thereby the raising that can not require because of welding quality and the reduction of application plastic squeeze speed have a negative impact to production efficiency.

The specific embodiment
As depicted in figs. 1 and 2, the welded structure of this automobile back wheel bulge and floor, back and floor side member comprises trailing wheel bulge 1, floor 2, back and floor side member 3; The three overlaps integrally welded, and at the overlap joint weld of trailing wheel bulge 1, floor 2, back and floor side member 3, floor side member 3 is between floor 2, back and trailing wheel bulge 1; Respectively with floor 2, back and trailing wheel bulge 1 welding; The upper limb of back floor 2 tie welding edge fits also welds with trailing wheel bulge 1, and afterwards floor 2 is positioned at the inboard, and rear drum 1 bag is positioned at the outside.
Claims (1)
