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
Back axle mainly connects the link of wheel, and its function is alleviate jolting of vehicle body, improves driving comfort.Be have higher intensity and toughness to the material requirements of back axle parts, structural requirement is simply compact, can content with funtion requirement.Existing back axle, back axle parts junction stress concentration phenomenon is comparatively serious, have impact on integrated carrying ability and the service life of structure, and welding process between shock absorber support and the dish of spring is more complicated, and welding quality difficulty controls.
Utility model content
For above-mentioned technical matters, the utility model provides the rear axle structure of the strong long service life of a kind 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 V-beam, be fixed on the trailing arm at V-beam two ends by stabilizer rod, be arranged on the shock absorber support between trailing arm and spring tray, the spring tray being erected at V-beam and trailing arm place and the flanged plate be fixed on trailing arm, the bottom at described V-beam two ends has arc notch, elongated afterbody is left at the two ends of arc notch, the two ends of V-beam are provided with groove, and described groove is all positioned at inside arc notch.
Further, the degree of depth of described groove is 3mm-15mm, and the described arc notch degree of depth is 5mm-80mm, and described afterbody is long is 5mm-80mm.
Further, described stabilizer rod two ends are also provided with stabilizer rod brace panel, described stabilizer rod brace panel is located at the bending place of trailing arm and is fixed by stabilizer rod and trailing arm, is provided with elasticity space between described stabilizer rod brace panel 4 and the bending place of trailing arm 2, and the thickness of described stabilizer rod brace panel is 4mm-7mm.
Further, described shock absorber support upper side has hole, and shock absorber support side joint edge connects with a side of spring tray, and in hole, the upperlimit of point-to-point transmission is 15mm-30mm.
Further, have hole above described flanged plate, the upperlimit between any two points of hole inside edge is 15mm-30mm, and flanged plate is with elongated afterbody, and the length of afterbody is 5mm-60mm.
The beneficial effects of the utility model are: when not increasing back axle material, by changing the connection mode of V-beam, trailing arm, shock absorber support, spring tray and flanged plate, improve the load-carrying capacity of structure, and utilize the design of hole and elongate tail, the phenomenon that the stress significantly reducing flanged plate and rear pontic junction is concentrated, improve the service life of structure, and simplify welding process, ensure that weldquality.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram;
Fig. 2 is the structure for amplifying schematic diagram of back axle in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of rear axle structure, comprise V-beam 1, the trailing arm 2 at V-beam two ends is fixed on by stabilizer rod 3, be arranged on the shock absorber support 5 between trailing arm 2 and spring tray 6, the spring tray 6 being erected at V-beam 1 and trailing arm 2 place and the flanged plate 7 be fixed on trailing arm 2, the bottom at described V-beam 1 two ends has arc notch 11, described arc notch 11 degree of depth is between 5mm-80mm, elongated afterbody 12 is left at the two ends of arc notch 11, described afterbody 12 is long between 5mm-80mm, the two ends of V-beam 1 are provided with groove 13, the degree of depth of described groove is 3mm-15mm, described groove 13 is all positioned at inside arc notch 11, groove 13 contributes to alleviating structural stress and concentrates.In order to strengthen the intensity of the bending place of trailing arm 2, described stabilizer rod 3 two ends are also provided with stabilizer rod brace panel 4, described stabilizer rod brace panel 4 is located at the bending place of trailing arm 2 and is fixed by stabilizer rod 3 and trailing arm 2, the thickness of described stabilizer rod brace panel 4 is 4mm-7mm, be provided with elasticity space between described stabilizer rod brace panel 4 and the bending place of trailing arm 2, described stabilizer rod brace panel 4 can reduce the stress intensity of commissure.Described shock absorber support 5 upper side has hole 51, and hole 51 can slow down stress concentration phenomenon, and shock absorber support side joint edge connects with a side of spring tray, and shock absorber support 5 can guarantee the quality of this weld seam with the connection mode of spring tray 6,
In hole, the upperlimit of point-to-point transmission is 15mm-30mm.Described flanged plate 7 has hole 71 above, and the upperlimit between any two points of hole 71 inside edge is 15mm-30mm, and flanged plate 7 is with the elongated afterbody 72 for slowing down stress concentration phenomenon, and the length of afterbody 72 is 5mm-60mm.
Rear axle structure in the present embodiment can reduce the stress concentration phenomenon of back axle parts junction significantly, improves the weldquality of shock absorber support 5 and spring tray 6 junction.
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.
