Abstract
The utility model discloses a drive axle housing, and belongs to the technical field of automobile components. On the premise of not increasing the wall thickness of an axle housing, the rated axle load of the drive axle housing can be further improved. The structure of the axle housing is that a rectangular section transits to a circular section, and the length of the rectangular section structure is 80% of that of the whole axle housing, so that the bending resistance coefficient of the axle housing is effectively increased; the width of a mounting plane of a main reducer is less than that of the rectangular section of the axle housing, so as to meet requirements on section design parameters; as surrounded ribs are adopted for reinforcing, feeble locations of the axle housing are strengthened pointedly, the increase of the wall thickness of the axle housing is avoided to enable the wall thickness of the axle housing to be uniform, hot spot structures are effectively reduced, defects of shrinkage porosity, shrinkage cavity and the like in the casting process can be overcome, and the yield is high.
Description
Technical field
The utility model belongs to technical field of automobile parts, relates to transaxle axle case of heavy duty car.
Background technology
Driving axle of heavy automobile shell is one of topmost part in whole bridge, plays the load-carrying of supporting vapour, and load is passed to wheel.The tractive force, braking force, side force and the vertical force that act on wheel are also to pass on suspension and vehicle frame through axle housing, so Drive axle housing is load member and force transmission element.Drive axle housing adopts integral casting process conventionally, can be made into complexity and desirable shape.Because limiting with main reduction gear installation site on axle housing, cause axle housing cross section not design according to actual load demand, cause axle housing undercapacity, as shown in Figure 1.If continuity old structure axle housing, meet limiting condition, axle housing must be thickeied wall thickness, causes weight, thermal center structure to increase, cause because wall unevenness is even being prone to the defect such as shrinkage porosite, shrinkage cavity in casting process, and reject rate is high.
Utility model content:
The technical matters that the utility model solves is to provide a kind of Drive axle housing, is not increasing in axle housing wall thickness situation, and the specified axle load of Drive axle housing has further been improved.
The technical solution of the utility model is, a kind of Drive axle housing, and the both sides of axle housing are all transitioned into circular section by square-section gradually, and the ratio that makes the length of square-section, axle housing both sides account for whole axle housing length is greater than 80%; Main reduction gear mounting plane is lower than axle housing square-section height, with axle housing square-section rounding off; The two edges up and down of the both sides, front and back of axle housing are around muscle, and one end leaf spring face around muscle along axle housing edge from axle housing is to other end leaf spring face.
Preferably, the reference position that is transitioned into circular section by square-section is the initial section of leaf spring face.
Preferably, the upper and lower leaf spring face size of axle housing is identical, and is made as squarely, and the edge, left and right of the two sides, front and back of leaf spring face place axle housing adds stud.
Preferably, after axle housing, through hole bearing lubrication oil duct tilts.
Technique effect of the present utility model is: axle housing structure of the present utility model is that square-section is transitioned into circular section, and rectangular cross section structure length accounts for 80% of whole axle housing length, effectively strengthens the bending coefficient of axle housing.Main reduction gear mounting plane lower than axle housing square-section width to meet Cross section Design parameter demand.Take not only targetedly axle housing weak location to be strengthened around the reinforcement mode of muscle, and avoid axle housing wall thickness to increase, make axle housing wall thickness even, effectively reduce the defect such as shrinkage porosite, shrinkage cavity in thermal center structure, casting, yield rate is high.

Detailed description of the invention
Drive axle housing of the present utility model is that existing Drive axle housing is improved, and further the utility model is described in detail below in conjunction with accompanying drawing.
A kind of Drive axle housing of the present utility model, bridge bag in the middle of comprising, the flange at two ends, the spring block between bridge bag and each flange, the axle housing supporter of connecting bridge bag, spring block, flange, is positioned at the reinforcing pad of the open circumferential of the cavity in the middle of axle housing supporter; The outside face of reinforcing pad is main reduction gear mounting plane 1 (Chinese lute face).Symmetrical on axle housing length direction, therefore the flange at two ends is symmetrical, and the spring block on both sides is symmetrical.Spring block is a plane of placing the seat of leaf spring.
1. Drive axle housing structure of the present utility model is transitioned into circular section 4 by square-section 3, the reference position that is transitioned into circular section 4 by square-section 3 is that leaf spring face is near the initial section of one end end face at axle housing center, the ratio that makes the length of square-section, axle housing both sides 3 account for whole axle housing length is greater than 80%, as shown in Figure 4.
2. main reduction gear mounting plane 1 (Chinese lute face) is embedded, and this plane is lower than axle housing square-section 3 height, with axle housing square-section 3 rounding ofves.
3. the both sides of the edge of axle housing are provided with around muscle structure 2, share axle housing and act on the stress on axle housing cross section.One end leaf spring face around muscle along axle housing edge from axle housing is to other end leaf spring face 6; As shown in Figure 4; As shown in Figure 2,3, being positioned at the upper lower edge of the two sides, front and back of axle housing around muscle, around the general rectangle in muscle cross section, is that the rectangle of projection is rectangular.
4. the upper and lower leaf spring face of axle housing 6 sizes are identical, and are made as squarely, and the edge, left and right that upper and lower leaf spring face 6 (shown in Fig. 2,3) is located the two sides, front and back of axle housing adds stud 5, as shown in Figure 4; Axle housing leaf spring face place adopts this structure, not only strengthens the antitorque coefficient in leaf spring face place, meets the feasibility of axle housing foundry technique simultaneously.
5. after axle housing, through hole bearing lubrication oil duct 7 tilts, the invariant position that oil duct 7 is communicated with rear through hole, and oil duct 7 other end height increase, and make axle housing inner gear lubricating oil more easily enter oil duct and flow into bearing again and be lubricated, as shown in Figure 5.
The specified axle load that carries out improved axle housing according to said structure can reach 40 tons.
