Abstract
The utility model relates to a driving bridge casing body of a wheel type loader, which belongs to the field of engineering machines, particularly the field of driving bridges of wheel type loaders. Frame connection bearing surfaces are arranged on both sides of the center of the hollow driving bridge casing body; circular holes on the middle side are used for connecting with the main transmission of the driving bridge; the integral type hollow driving bridge casing body can be formed by the welding connection of two open type half side bridge casings of which the cross sections are formed from a hemicycle segment, a rectangular segment and a transition segment between the hemicycle segment and the rectangular segment; reinforcing rib plates are axially arranged in welding connection from the end heads of the two half side bridge casings to the inner cavity wall of the frame connection bearing surfaces. The middle side of the driving bridge is provided with circular connecting rings for the welding connection with the bridge casing body, the other side is provided with a spirogyrate thin wall sealing cover for the welding connection with the bridge casing body. The utility model is mainly used for the field of driving bridges of engineering machines so as to replace the original castings and has the advantages of light material, material saving, low cost, uniform material, controllable quality and favorable reliability for solving the original accident of easy break.
Description
Affiliated technical field
The utility model relates to a kind of engineering machinery, especially Driving Axle of Wheel Loader.
Background technology
At present, known engineering machinery drive axle, especially Driving Axle of Wheel Loader housing, cast by cast steel or vermiform ductile iron, make through machining, problems such as ubiquity wall thickness, allowance is many, consumptive material is many, cost is high, inherent quality is unstable, dependability difference, the driving axle housing physique amount gap that professional bridge factory produces is big, the time axle housing fracture is arranged, cause potential safety hazard.
Summary of the invention
For overcoming the engineering machinery drive axle, especially the Driving Axle of Wheel Loader housing adopts casting weight weight, processing time consuming, cost height, inherent quality controllability difficulty, cause poor reliability and breakage problem, the utility model provides a kind of design scheme, not only in light weight, the production efficiency height, cost is low, and stable and controllable for quality, the reliability height.
The technical scheme that its technical problem that solves the utility model adopts is: have vehicle frame to connect bearing surface on hollow drive axle housing, the half of axle housing of open type that section is made of the changeover portion between semi-circular section, rectangular section and semicircle and the rectangle, two half of axle housings connect and compose a hollow drive axle housing of monolithic through seam, connect the bearing surface internal chamber wall in its termination to vehicle frame and be provided with and strengthen gusset vertically, connect with seam.Have circular clamping ring to be connected with the seam of axle housing body in a middle side, opposite side has the capping of spirogyrate thin-walled to be connected with the seam of axle housing body.Center circle both sides outer wall studs with triangle and inserts, and connects by seam.
Two half of axle housings forming the drive axle housing are identical, and about, up and down the symmetry, by the steel plate press forming, behind the press forming reinforcing rib is welded in two ends to vehicle frame junction plate place internal chamber wall, again two half of axle housing seam are connected, at last triangle is inserted, clamping ring, capping and vehicle frame connect supporting faceplate and axle housing seam.Again through processing, its termination outside cylinder part was connected by temperature difference interference assembling and seam with the hub carrier endoporus, fixes with pivot pin, or connects through mechanical system after whole drive axle housing seam connected.
The beneficial effects of the utility model are: weight reduces by half than foundry goods, and production link pollutes little, the production efficiency height, and cost is low, material is even, and is quality controllable, and intensity, rigidity are guaranteed, the reliability height, any surface finish is attractive in appearance, and inner chamber does not have scab, and cleannes are good, and the travelling gear life-span is long.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the utility model Facad structure view, because of bilateral symmetry, only draws half.
Fig. 2 is its corresponding vertical view.
Among the figure, 1, half of axle housing, 2, muscle, 3, vehicle frame connects bearing surface, 4, rectangular cross section, 5, weld seam, 6, triangle inserts, 7, weld seam, 8, weld seam, 9, changeover portion, 10, circle cross section, 11, pin-and-hole, 12, vehicle frame installs screw, 13, weld seam, 14, capping, 15, clamping ring, 16, connect screw, 17, weld seam, 18, weld seam, 19, hub carrier.
The specific embodiment
In the drawings, half of axle housing (1) section is made of the changeover portion between semi-circular section, rectangular section and semicircle and the rectangle, suppress by steel plate, muscle (2) generally uses weld seam (8) seam to be connected on two half of axle housings (1) internal chamber wall respectively by four, connect in aggregates with weld seam (7) seam two half of axle housings (1) again, triangle insert (6) avoid using heterotype profiled sheet for half of axle housing (1) compacting and cause waste to design, can make of tailing.Vehicle frame connects bearing surface (3) and places between axle housing center and circle cross section (10) termination with plate, and is connected with the axle housing seam, as shown in the figure about, about totally four, vehicle frame installation screw (12) is used for being connected with vehicle frame on it.A side has evagination thin-walled capping (14) to be connected with its seam by weld seam (13) in the middle of the drive axle housing, and opposite side has clamping ring (15) to be connected with its seam with weld seam (17), connects screw (16) and is used for being connected with the drive axle main transmission section.The drive axle housing is circle and hub carrier (19) employing temperature difference interference assembling outside its termination circle cross section (10) after processing, and fixing through pin-and-hole (11) with pivot pin, connects through weld seam (18) and reinforces.
Claims (3)
1, a kind of Driving Axle of Wheel Loader housing, the both sides, center have vehicle frame to connect bearing surface on hollow drive axle housing, a middle side has unlimited circular port, it is characterized in that: the half of axle housing of open type that section is made of the changeover portion between semi-circular section, rectangular section and semicircle and the rectangle, two half of axle housings connect and compose a hollow drive axle housing of monolithic through seam, connect the bearing surface internal chamber wall in its termination to vehicle frame and be provided with and strengthen gusset vertically, connect with seam.
