Abstract
The utility model discloses a kind of rear axle structure, comprise rear pontic and be located at the frame shake device support and spring tray of rear pontic both sides, the position that described shock absorber support is connected with spring tray is positioned at the side of spring tray, the position that shock absorber support is connected with spring tray is positioned at the side of spring tray, simplify welding process, more easily guarantee welding quality, when not increasing shock absorber support material, by arranging the hole of release stress, significantly reduce the stress concentration phenomenon of shock absorber support and spring tray junction, improve load-carrying capacity and the service life of structure.
Description
Technical field
The utility model relates to a kind of vehicle installation accessory, particularly relates to a kind of rear axle structure be assemblied on motor-vehicle chassis.
Background technology
As shown in Figures 3 and 4, existing rear axle structure generally comprises rear pontic 1a and is located at shock absorber support 2a and the spring tray 3a of rear pontic 1a both sides, shock absorber support 2a mainly connects the link of bumper in back axle, have higher intensity and toughness to the material requirements of shock absorber support parts, structural requirement is simply compact, can meet the functional requirement of back axle.Existing shock absorber support 2a, as shown in Figure 3, serious with spring tray 3a junction stress concentration phenomenon, have impact on integrated carrying ability and the service life of structure.In addition, the connection more complicated between existing shock absorber support 2a and spring tray 3a, is not easy to welding procedure, and welding quality is difficult to ensure.
Utility model content
For above-mentioned technological deficiency, the utility model proposes a kind of welding process simple, be convenient to ensure welding quality, and the rear axle structure of the strong long service life of load-carrying capacity.
Be exactly problem to solve above-mentioned, the technical solution of the utility model is as follows:
A kind of rear axle structure, comprise rear pontic and be located at frame shake device support and the spring tray of rear pontic both sides, the position that described shock absorber support is connected with spring tray is positioned at the side of spring tray.
Further, hole is offered in described shock absorber support side, and the upperlimit of described hole edge point-to-point transmission is no more than 60mm, and the minimum radius of hole Inner arc is not less than 1.5mm.
Further, described shock absorber support is offered the adjacent spring tray in that side of hole.
The beneficial effects of the utility model are: the side position that shock absorber support is connected with spring tray being positioned at spring tray, simplify welding process, more easily guarantee welding quality, when not increasing shock absorber support material, by arranging the hole of release stress, significantly reduce the stress concentration phenomenon of shock absorber support and spring tray junction, improve load-carrying capacity and the service life of structure.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram;
Fig. 2 is the structure for amplifying schematic diagram of shock absorber support and spring tray in Fig. 1;
Fig. 3 is existing rear axle structure schematic diagram;
Fig. 4 is the structure for amplifying schematic diagram of shock absorber support and spring tray in Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, structure of front auxiliary frame in this example comprises rear pontic 1 and is located at shock absorber support 2 and the spring tray 3 of rear pontic 1 both sides, the position that shock absorber support 2 is connected with spring tray 3 is positioned at the side of spring tray 3, shock absorber support 2 in the present embodiment there is the hole 21 of release stress, the upperlimit of described hole edge point-to-point transmission is no more than 60mm, the minimum radius of hole Inner arc is not less than 1.5mm, by arranging this hole 21, effectively can slow down the stress concentration phenomenon that bumper props up 2 frame junctions, the side having hole 21 on described shock absorber support 2 is close to spring tray 3, this setting is not only for increasing technological process, and compare traditional structure, shock absorber support 2 welding process in the present embodiment is simple, weldquality is easy to ensure.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
Claims (3)
1. a rear axle structure, comprise rear pontic and be located at shock absorber support and the spring tray of rear pontic both sides, it is characterized in that, the position that described shock absorber support is connected with spring tray is positioned at the side of spring tray.
