Description
Technical field
The utility model is related to a kind of through drive axle roller gear housing structure of reduction radiated noise, belongs to vapour
Car drive axle technical field.
Background technology
Automobile drive axle in use, is also easy to produce noise problem, has a strong impact on to multiply and drives comfortableness, while to external rings
Cause noise pollution in border.The main cause that axle noise is produced is as follows：One is driving and driven bevel gear etc. because of flank engagement position
The meshing noise that the reason such as the fluctuation of incorrect, driving error is big and Superposition degree modulus is not high is produced, two be that bearing rotates in high speed
During motion because the form error of raceway face and rolling element collide each other formed by contact noise.Two kinds of above-mentioned noises
Bang path, one way in which is by outwardly being radiated positioned at the roller gear housing of through drive axle front position
Go out.Common through drive axle roller gear housing is using outer surface without reinforcement, few reinforcement or divergence form reinforcement
Structure, when being assembled on axle assembly, the Integral modes and acoustic characteristic of housing are poor, and radiated noise is larger.
The content of the invention
The purpose of this utility model is to provide a kind of through drive axle roller gear housing knot of reduction radiated noise
Structure, it, which is used, carries out parallel muscle and circumference in cylindrical gear shell outer surface to diverging muscle synthesis arrangement, improves roller gear housing
Mode and acoustic characteristic, reduce through drive axle cylindrical gear shell outwardly radiated noise grade.
What the technical solution of the utility model was realized in：It is a kind of to reduce the through drive axle cylinder of radiated noise
Gear housing structure, it is characterised in that：The edge of gear housing is a circle flange body, and gear housing is provided with a bearings
Body and shaft space difference speed lock supporter, other positions are roller gear inclusion body, and the surface layout of gear housing has 5 reinforcements
Muscle, the thickness of reinforcement is 6-12mm, and the specific arrangement of reinforcement is to extend to flange body from bearing supporting body outer peripheral edge
Outer fringe position, wherein the first reinforcement and the second reinforcement are arranged in bearing supporting body side, the 3rd reinforcement is arranged in bearing
Supporter opposite side, the first reinforcement and the second reinforcement and the 3rd reinforcement are parallel to each other, and are spaced per between the reinforcement of side
Distance is 30-80mm, and the 4th reinforcement and the 5th reinforcement circumference centered on bearing supporting body stretch out, the 4th reinforcement
To be arranged with the 5th reinforcement and the first reinforcement, the second reinforcement, the 3rd reinforcement in angle, specific angular range is 30 °-
80°；The roller gear inclusion body of gear housing presses driven wheel of differential outline contoured design, roller gear inclusion body and Cylinder Gear
It is 5-25mm to take turns outline gap.
Good effect of the present utility model be the parallel muscle of roller gear housing outer surface and circumference diverging muscle integrate arrangement with
And small intracavity structure, improve roller gear housing characteristics of mode and acoustical behavior, can effectively reduce housing and outwardly radiate and make an uproar
The rank of sound；The arrangement of reinforcement adds the lubricating oil temperature in the area of dissipation of cylindrical gear shell outer surface, reduction shell, changes
It has been apt to the working environment of the parts such as gear, has extended drive axle service life.
Brief description of the drawings
Fig. 1 is Facad structure figure of the present utility model.
Fig. 2 is bottom surface structure figure of the present utility model.
Fig. 3 is attachment structure figure of the utility model on penetrating bridge.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：As Figure 1-3, it is a kind of to reduce passing through for radiated noise
Flow-through drive axle roller gear housing structure, it is characterised in that：The edge of gear housing is a circle flange body 1, gear housing
Provided with a bearing supporting body 3 and shaft space difference speed lock supporter 4, other positions are roller gear inclusion body 2, gear housing
Surface layout have 5 reinforcements, the thickness of reinforcement is 6-12mm, and the specific arrangement of reinforcement is from bearing supporting body 3
Outer peripheral edge extends to the outer fringe position of flange body 1, wherein the first reinforcement 5 and the second reinforcement 6 are arranged in bearing supporting body 3 one
Side, the 3rd reinforcement 7 is arranged in the opposite side of bearing supporting body 3, the first reinforcement 5 and the second reinforcement 6 and the 3rd reinforcement 7
It is parallel to each other, is 30-80mm per spacing distance between the reinforcement of side, the 4th reinforcement 8 and the 5th reinforcement 9 are with bearing supporting body
Circumference stretches out centered on 3, and the 4th reinforcement 8 and the 5th reinforcement 9 and the first reinforcement 5, the second reinforcement the 6, the 3rd add
Strengthening tendons 7 arranges that specific angular range is 30 ° -80 °, forms the control of active force when being engaged to roller gear in angle；Gear hub
The roller gear inclusion body 2 of body presses driven wheel of differential outline contoured design, reduce the volume of housing die cavity, roller gear bag
Volume 2 and roller gear outline gap are 5-25mm, at the same with flange body 1 and the fusion connection of bearing block supporter 3.
Roller gear housing acoustics and characteristics of mode optimization analytical conclusions：In 400~3000Hz, the utility model radiation
Acoustic power level reduces 2.1dB (A).
In summary to the comparative analysis of roller gear housing, the utility model can effectively improve the characteristics of mode of housing,
The rank of housing outwardly radiated noise is reduced, the performance of automobile drive axle is improved.
