Abstract
The utility model provides a kind of main reducing gear of drive axle shell with oil collector sump tank, one oil baffle disc of position installation in final drive casing body, parallel with driven wheel of differential, the oil baffle disc is thin-slab structure, using sheet metal forming technology shaping, the bottom section of bevel housing is divided into two parts by oil baffle disc, side is driven wheel of differential region, and the other side is region when lubricating oil flow back into housing bottom where oil liquid；The lubrication oil catch for flowing back into bevel housing bottom in the other side of driven wheel of differential, is avoided driven wheel of differential from touching excessive lubricating oil, oily power loss is stirred in generation by the oil baffle disc；Oil pump extracts lubricating oil from lubricating oil region, carries out circulation lubrication to position each in drive axle, improves the transmission efficiency of drive axle.
Description
Technical field
The utility model belongs to automobile drive axle structure-design technique field, in particular to a kind of drive with oil collector sump tank
Dynamic bridge bevel housing.
Background technique
As automobile is higher and higher to the requirement in terms of energy-saving and emission-reduction, improves the transmission efficiency of drive axle, reduces vehicle oil
Consumption becomes the main trend of drive axle development.The transmission efficiency loss of drive axle is mainly generated by following several respects reason: driving
What gear rotation drive lubricating oil generated when bridge works stirs power loss and bearing support caused by oily power loss, gear engagement
Pivoting friction caused by power loss, wherein stirring oily power loss refers to that the lubricating oil of drive axle is present in bevel housing
Interior, when drive axle work, lubricating oil recycles inside main reducing gear, is lubricated to each part, completes the lubricating oil of circulation
Bevel housing bottom is returned to, a large amount of lubricating oil are gathered in the bottom of bevel housing at this time, are in driven wheel of differential
In the same cavity, the driven wheel of differential being operated is stirred, and oily power loss is stirred in generation；Reduce gear rotation generation stirs oil
Power loss can generate very big contribution to the transmission efficiency for improving entire drive axle, but in current drive axle structure, not
Have for the concrete measure for stirring oily power loss is reduced, therefore, how to reduce drive axle and stir oily loss in efficiency, improve transmission efficiency
At current focus on research direction.
Summary of the invention
In order to overcome the above problem, the utility model provides a kind of main reducing gear of drive axle shell with oil collector sump tank,
One oil baffle disc of position installation in final drive casing body, parallel with driven wheel of differential, which is thin-slab structure, is used
The bottom section of bevel housing is divided into two parts by sheet metal forming technology shaping, oil baffle disc, and side is driven wheel of differential place
Region, the other side are regions when lubricating oil flow back into housing bottom where oil liquid；The oil baffle disc will flow back into final drive casing
The lubrication oil catch of body bottom avoids driven wheel of differential from touching excessive lubricating oil, generation is stirred in the other side of driven wheel of differential
Oily power loss；Oil pump extracts lubricating oil from lubricating oil region, carries out circulation lubrication to position each in drive axle, improves
The transmission efficiency of drive axle.
A kind of main reducing gear of drive axle shell with oil collector sump tank, including bevel housing 2 and oil baffle disc 1, wherein
Bevel housing 2 is equipped with boss 21, and boss 21 is equipped with mounting groove, peace of 1 tight fit connection of oil baffle disc on boss 21
In tankage, realize that oil baffle disc 1 is fixed in mounting groove, 2 cavity bottom of bevel housing is provided with oil-sucking hole 22.
The utility model has the beneficial effects that
The utility model is by installing an oil baffle disc in main reducing gear of drive axle shell bottom, by bevel housing bottom
It is divided into two regions, the lubricating oil for flowing back into final drive casing bottom is made largely to be isolated in the other side of driven wheel of differential,
Driven wheel of differential touches excessive lubricating oil when avoiding drive axle work, and generation stirs oily power loss, improves drive axle
Transmission efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model partial structural diagram.
Fig. 3 is the utility model final drive casing partial structural diagram.
Fig. 4 is the utility model scheme of installation.
Wherein: 1 oil baffle disc, 2 bevel housings, 21 boss, 22 oil-sucking holes, 3 driven wheel of differential.
Specific embodiment
The specific embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings:
A kind of main reducing gear of drive axle shell with oil collector sump tank, as shown in Figure 1, Figure 2 and Figure 3, including main reducing gear
Shell 2 and oil baffle disc 1, wherein bevel housing 2 is equipped with boss 21, and boss 21 is equipped with mounting groove, 1 tight fit of oil baffle disc
It is connected in mounting groove, realizes that oil baffle disc 1 is fixed in mounting groove, 2 cavity bottom of bevel housing is provided with oil-sucking hole 22.
As depicted in figs. 1 and 2, oil baffle disc 1 is thin-slab structure, using sheet metal forming technology shaping, shape and final drive casing
The bottom surface of body 2 is bonded；As shown in figure 3, casting out boss 21 everywhere on bevel housing 2, use is processed on boss 21
In the mounting groove of installation oil baffle disc 1, for fixing oil baffle disc 1, as shown in figure 4, driven wheel of differential 3 is in the left side area of oil baffle disc 1
Domain, the lubricating oil in bevel housing 2 flow back into the right area of oil baffle disc 1 at this time, touch driven wheel of differential 3 will not
A large amount of lubricating oil, oil pump siphons away the lubricating oil for flowing back into 2 bottom of bevel housing from oil-sucking hole 22, in main reducing gear
Each critical component in portion is lubricated.
A kind of main reducing gear of drive axle shell with oil collector sump tank, including bevel housing 2 and oil baffle disc 1, wherein
Bevel housing 2 is equipped with boss 21, and boss 21 is equipped with mounting groove, and 1 tight fit connection of oil baffle disc is realized in mounting groove
Oil baffle disc 1 is fixed in mounting groove, and 2 cavity bottom of bevel housing is provided with oil-sucking hole 22.
