Abstract
The utility model relates to vehicle component processing technique field, specifically relates to a kind of lightweight axle housing.Comprise circular mounting cylinder and be placed in circular mounting cylinder top for installing the axle housing body of leaf spring, this axle housing bodies top has limiting stopper, and be axle housing leaf spring groove between two limiting stoppers, the two ends of this axle housing leaf spring groove have downward-sloping sloping platform.Lightweight axle housing of the present utility model, the structure of leaf spring groove is improved, adds the chamfering shape sloping platform at leaf spring groove two ends, because leaf spring groove both sides end face does not contact with leaf spring, by the middle part transfer dispersion of the antagonistic force of leaf spring to axle housing leaf spring groove, stress is avoided to concentrate.Axle housing adopts tensile strength 900MPa, and the ADI material of yield strength 650MPa, the comprehensive mechanical property of this material is excellent, realizes lightweight.Under the prerequisite that improve axle housing bulk strength, to the suitable symmetrical hollow out in the position of the stressed reduction in leaf spring groove two ends, realize lightweight further, reduce costs.
Description
Technical field
The utility model relates to vehicle component processing technique field, specifically relates to a kind of lightweight axle housing.
Background technology
Axle housing is as the important feature part of heavy duty truck chassis part, and must have very high safety and reliability, material generally selects ZG310-570 or QT500-7.Its service conditions is severe, need bear and weigh and the live load changed greatly.Normal steel casting and magnesium iron only have by increasing the sectional area of component to meet operating needs, but this adds increased the chassis weight of automobile.So there is contradiction in lightweight trend with meeting in operating needs two, cost control simultaneously also becomes difficult point.Axle housing cracking leakage of oil situation is always unresolved.
Refer to Fig. 1, axle housing 3 is connected by saddle clamp 2 with leaf spring 1 in the course of the work, and leaf spring is stuck in axle housing leaf spring groove.Axle housing swings relative to the axle of balance shaft because of the vibrations of leaf spring, main by leaf spring vertical impact forces and front and back twisting resistance, and leaf spring groove two ends are due to from axle housing center farthest, therefore suffered twist moment is maximum.Learnt by cae analysis, common axle housing local stress when turning concentrates on leaf spring groove two ends, and is greater than the yield strength of ZG310-570 and QT500-7, and long service is the leakage of oil of axle housing cracking under this operating mode.
Utility model content
For the technical matters existed in prior art, the purpose of this utility model is to provide a kind of avoids stress to concentrate, improve the lightweight axle housing of axle housing bulk strength.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of lightweight axle housing, comprise circular mounting cylinder and be placed in circular mounting cylinder top for installing the axle housing body of leaf spring, this axle housing bodies top has limiting stopper, be axle housing leaf spring groove between two limiting stoppers, the two ends of this axle housing leaf spring groove have downward-sloping sloping platform.
In this lightweight axle housing, its inner recess of two side direction of described axle housing body forms the first hollow-out parts.
In this lightweight axle housing, the axle housing leaf spring groove described axle housing body is placed between two sloping platforms is recessed to form the second hollow-out parts downwards, and this second hollow-out parts runs through axle housing body along the outer wall of circular mounting cylinder.
In this lightweight axle housing, described circular mounting cylinder and axle housing body are shaping by austempering ductile iron material integrally casting.
Lightweight axle housing of the present utility model, its beneficial effect shows:
1), the structure of leaf spring groove is improved, add the chamfering shape sloping platform at leaf spring groove two ends, because leaf spring groove both sides end face (sloping platform) do not contact with leaf spring, by the middle part transfer dispersion of the antagonistic force of leaf spring to axle housing leaf spring groove, stress is avoided to concentrate.
2), axle housing adopts tensile strength 900MPa, the ADI material (austempering ductile iron) of yield strength 650MPa, the comprehensive mechanical property of this material is excellent, tensile strength and yield strength all than magnesium iron and cast steel high, the proportion of material own is less than cast steel, realizes lightweight.
3), under the prerequisite that improve axle housing bulk strength, to the suitable symmetrical hollow out in the position of the stressed reduction in leaf spring groove two ends, realize lightweight further, and can reduce costs.

Detailed description of the invention
For further describing the utility model, below in conjunction with drawings and Examples, the utility model is described in further detail.A kind of lightweight axle housing shown in Fig. 2-5, comprise circular mounting cylinder 10 and be placed in circular mounting cylinder 10 top for installing the axle housing body 11 of leaf spring, this axle housing body 11 top has limiting stopper 12, be axle housing leaf spring groove 13 between two limiting stoppers 12, the two ends of this axle housing leaf spring groove 13 have downward-sloping sloping platform 16.
Its inner recess of two side direction of axle housing body 11 forms the first hollow-out parts 15, the axle housing leaf spring groove 13 axle housing body 11 is placed between two sloping platforms 16 is recessed to form the second hollow-out parts 14 downwards, and this second hollow-out parts 14 runs through axle housing body 11 along the outer wall of circular mounting cylinder 10.
Circular mounting cylinder 10 and axle housing body 11 are shaping by austempering ductile iron material integrally casting.
Above content is only to design example of the present utility model and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
