Description
Technical field
The present invention relates to vehicle structure technical field, refer to particularly it is that a kind of Rear drag arm is installed attachment point structure.
Background technology
The installation attachment point of Rear drag arm is the important installation attachment point of rear suspension on vehicle body, the strength and stiffness that attachment point is installed directly have influence on riding stability, safety and the NVH performance of vehicle, therefore must guarantee that structure has enough intensity and rigidity herein.But because near of the installation attachment point at Rear drag arm needs to arrange the environment such as fuel tank, freeing pipe part, limited space, therefore design a kind of compact conformation, simple, the Rear drag arm installation attachment point structure again with enough strength and stiffness is just necessary simultaneously very much.
Summary of the invention
Object of the present invention is exactly the deficiency that will solve above-mentioned background technology, and a kind of compact conformation, simple is provided, and the Rear drag arm again with enough strength and stiffness is installed attachment point structure simultaneously.
Technical scheme of the present invention is: a kind of Rear drag arm is installed attachment point structure, comprise the Rear drag arm adapter plate for assembling Rear drag arm, it is characterized in that: described Rear drag arm adapter plate comprises multiple face of weld and an attachment face, described face of weld is welded on respectively floor side member, back rail junction plate and Rear drag arm are installed on outside plate, described back rail junction plate is fixedly connected with floor side member, described Rear drag arm is installed outside plate and is fixedly connected with floor side member, described attachment face is provided with the mounting hole that Rear drag arm is installed, longitudinal side of described attachment face both sides is provided with the bolt hole of getting through with mounting hole.
In such scheme: described Rear drag arm adapter plate is by a face of weld and floor side member and back rail junction plate welding.
The face of weld that described Rear drag arm adapter plate and Rear drag arm are installed outside plate welding is provided with two.
Described Rear drag arm is installed outside plate and is provided with five joint faces, and the face of weld that Rear drag arm adapter plate and Rear drag arm are installed outside plate welding matches with two joint faces wherein, and Rear drag arm is installed outside plate and is fixedly connected with floor side member by three joint faces.
In the present invention, by the welding of outside plate being installed with floor side member, back rail junction plate and Rear drag arm, making Rear drag arm adapter plate, by floor side member, back rail junction plate and Rear drag arm, outside plate is installed clamps, the fixed sturcture of Rear drag arm adapter plate forms a semienclosed clamp structure, this its compact conformation of semi-enclosed structure, simple, can save installing space, by Rear drag arm, outside plate is installed again and is realized further fixing between Rear drag arm adapter plate and floor side member, guarantee the strength and stiffness of Rear drag arm adapter plate.
In the present invention, Rear drag arm is arranged in the mounting hole in the attachment face of Rear drag arm adapter plate, then the bolt matching by a bolt hole being provided with longitudinal side of attachment face both sides is fixed, and has completed the installation of Rear drag arm.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present invention;
Fig. 2 is the present invention's structural representation that explodes;
Fig. 3 is the structural representation of Rear drag arm adapter plate in the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
A kind of Rear drag arm is as shown in FIG. installed attachment point structure, it comprises the Rear drag arm adapter plate 3 for assembling Rear drag arm, Rear drag arm adapter plate 3 is provided with multiple face of weld, wherein, the bottom surface of Rear drag arm adapter plate 3 is the first face of weld (not marking in figure), Rear drag arm adapter plate 3 welds by the first face of weld and floor side member 1 and back rail junction plate 2, a first face of weld part is welded with floor side member 1, another part and back rail junction plate 2 weld, and back rail junction plate 2 is fixedly connected with floor side member 1.Before Rear drag arm adapter plate 3, it is attachment face 3.1, attachment face 3.1 is provided with the mounting hole 3.2 that Rear drag arm is installed, longitudinal side of attachment face 3.1 both sides is provided with the bolt hole 3.3 of getting through with mounting hole 3.2, when installation, Rear drag arm is arranged in the mounting hole 3.2 in the attachment face 3.1 of Rear drag arm adapter plate 3, be fixed by a bolt matching with bolt hole 3.3 again, completed the installation of Rear drag arm.Longitudinal side of attachment face 3.1 1 sides is the second face of weld 3.4, adjacent with the second face of weld 3.4 face of weld is the 3rd face of weld 3.5, and Rear drag arm adapter plate 3 is installed outside plate 4 by the second face of weld 3.4 and the 3rd face of weld 3.5 with Rear drag arm and is welded and fixed.Rear drag arm is installed outside plate 4 and is provided with five joint faces, two joint faces wherein and the second face of weld 3.4 and the 3rd face of weld 3.5 match, Rear drag arm is installed outside plate 4 and is welded and fixed by other three joint faces and floor side member 1, by Rear drag arm, outside plate 4 is installed and can be realized further fixing between Rear drag arm adapter plate 3 and floor side member 1, guarantee the strength and stiffness of Rear drag arm adapter plate 3.
In the present invention, by the welding of outside plate 4 being installed with floor side member 1, back rail junction plate 2 and Rear drag arm, making Rear drag arm adapter plate 3, by floor side member 1, back rail junction plate 2 and Rear drag arm, outside plate 4 is installed clamps, the fixed sturcture of Rear drag arm adapter plate 3 forms a semienclosed clamp structure, this its compact conformation of semi-enclosed structure, simple, can save installing space, and Rear drag arm adapter plate have enough strength and stiffness installation Rear drag arms.
The present invention is simple in structure, and compactness is a kind ofly both can save installing space for the installation of miscellaneous part, can guarantee that again the novel Rear drag arm of the strength and stiffness of Rear drag arm adapter plate is installed attachment point structure.
