The specific embodiment
In order further to understand the technical solution of the utility model, characteristics and advantage, the compound type axle-hang box structure that the utility model proposes is done further to describe below in conjunction with drawings and the specific embodiments.
Shown in Fig. 1,1A, the compound type axle-hang box structure that the utility model proposes, have a middle housing 2 and two bear boxs 1,1 ', described two bear boxs 1,1 ' are fixedly welded on the two ends of middle housing 2, on middle housing 2, be provided with the reinforcement gusset, middle housing 2 is provided with two wing plates vertically, is provided with gear case Holder for hanging household utensiles 3 at an end of described middle housing 2.
In order to reduce by defectives such as being mingled with of producing of casting, pore, butterfly-shaped shortbreads as far as possible, the middle housing 2 of axle suspension bearing box unitized construction of the present utility model and two bear boxs 1,1 ' are moulding respectively, promptly this bear box is separating with middle housing 2 with the motor part that face 24 joins of healing up, and crackle often the regional area at the place of sending out improve castability and reduce or avoid foundry defect, then with two bear boxs 1,1 ' and middle housing 2 welding be fixed into an integral body, and utilize ultrasonic flaw detection to guarantee welding quality, at last, be reprocessed into the shape of needs and the surface of requirement.Position while welding during welding has been avoided the area of high stress of structure, for example, shown in Fig. 3,4, bear box 1,1 ' and the weld seam 5 of middle housing 2 be arranged on the bear box inboard, to avoid the district occurred frequently of cracks of axle-hang box, the end sections of middle housing 2 stretches in the bear box, and carries out weld from both sides and connect, thereby has avoided because the new formation of crack that weld defect brings.
Shown in Fig. 5 A to Fig. 6 B, the utility model also can change the bear box of aforementioned cast structure into the bear box of forging structure.Left and right sides bearing housing 1,1 ' comprises that arc transition place (area of high stress) all adopts the open die forging forging method, and left and right sides bearing housing 1,1 ' is forged into hollow cylindrical structures.Thus, can avoid fully producing various defectives, increase the density and the homogeneity of material, improve its comprehensive strength by casting.
Shown in Fig. 7 A, 7B, middle housing 2 can be made by thicker solid drawn pipe, earlier processing simultaneously inside and outside the solid drawn pipe is obtained cylinder, after finishing cylinder and bear box 1,1 ' welding, again cylinder is cut open a breach and be worked into the size and the surface accuracy of requirement, obtain described middle housing 2, thus out of roundness and the too big defective of opening size error that can avoid roll of steel plate system to cause.
The wing plate 4 of compound type axle-hang box structure of the present utility model also can independent moulding, shown in Figure 1A, Fig. 8 A, Fig. 8 B, this wing plate 4 can be "
" type, i.e. wing plate 4 both end sides and motor erecting bed junction thickening is provided with.After middle housing 2 and bear box 1,1 ' welding are fixed, again two wing plates 4 are symmetrically welded the breach both sides of being fixed in the middle housing 2 that is made of steel pipe vertically, then motor erecting bed and two wing plates 4 are lumped together.
In order further to strengthen the intensity of casing, can add the reinforcement gusset at the appropriate location of middle housing 2, as shown in Figure 1, be provided with reinforcement gusset 21 vertically in the outside of middle housing 1, along the circumferential direction between two wing plates 4 and shaft orientation reinforcing rib plate 21, be respectively equipped with and strengthen gusset 23, in addition, also can correspondingly establish reinforcement gusset 22 at wing plate 4 by wide each corner that narrows down.Be provided with a Holder for hanging household utensiles gusset 31 between on gear case Holder for hanging household utensiles 3 and the middle housing 2 in addition.
By Fig. 1,2,3,4 as can be seen, the main stressed member of compound type axle-hang box structure of the present utility model adopts forging, greatly reduces the probability that crackle takes place, and its strength at repeated alternation is apparently higher than former cast structure, and increase service life greatly; And each parts and the general exchange of former cast structure energy can effectively reduce production and operation cost in the comprehensive strength that guarantees axle-hang box.Through overtesting and calculating, estimate that can reach more than 1,200,000 kilometers the service life of compound type axle-hang box structure of the present utility model, be higher than the service life of known technology far away, therefore, have high economic benefit and social benefit.
The above person only; only be specific embodiment of the utility model, when can not with the scope implemented of qualification the utility model, so the displacement of its equivalent assemblies; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.
