Abstract
The utility model relates to drive axle transmissions, to solve the problems, such as that lubricating oil can flow into drive axle inner cavity and leads to front end retarder lack of lubrication existing machine in front end retarder when going up a slope, the utility model constructs a kind of drive axle front end retarder independent lubricating structure, including drive axle and front end retarder, the shell of front end retarder is fixedly connected with the bracket of drive axle, the output shaft of front end retarder and the active spiral bevel gear shaft of drive axle connect, the output shaft outer circumference surface of front end retarder is stretched out with output shaft on reducer shell has the gap for being connected to reducing gearbox inner cavity between the hole wall in hole, the oil sealing that isolation reducing gearbox inner cavity is connected to by gap with outside is provided between the output shaft of front end retarder stretches out hole hole wall with output shaft on reducer shell.Lubricating oil in retarder cannot flow into drive axle inner cavity by gap, to realize that there is machine retarder when going up a slope enough lubricating oil to be lubricated to internal transmission part and seal member.
Description
Technical field
The utility model relates to a kind of transmissions of drive axle, more specifically to a kind of drive axle front end retarder independence
Lubrication system.
Background technique
The bridge of mating fully-hydraulic vibration roller, generally can be in one group of epicyclic reducer of Front-end Design, for increasing bridge
The speed ratio of assembly.The shell of retarder and the bracket of drive axle connect, the active spiral shell installed on the output shaft and bracket of retarder
The shaft for revolving bevel gear is connected by spline, and the shaft of active spiral bevel gear is mounted on bracket by bearing.Retarder
There is the gap being connected to reducing gearbox inner cavity, therefore, between front end reducer output shaft and shell between shell and output shaft
Gap, active spiral bevel gear the axial gap of turning form the company that the inner cavity of front end retarder is connected to drive axle inner cavity
Circulation passage realizes the flowing of internal lubrication oil.But the lubricating oil when machine goes up a slope in retarder then passes through above-mentioned communicating passage
Drive axle inner cavity is flowed under gravity, reducing gearbox inner cavity lubricating oil is caused to reduce, if machine is for a long time again in slope surface
Work, it will cause cause transmission parts and seal member in retarder that cannot lubricate in retarder because lacking lubricating oil
With cooling and premature deterioration, cause the lost of life.
Utility model content
The technical problems to be solved in the utility model is that when going up a slope, lubricating oil can flow into drive to machine in the retarder of front end
The problem of moving bridge inner cavity and leading to front end retarder lack of lubrication, and a kind of drive axle front end retarder independent lubricating knot is provided
Structure so that front end retarder inner cavity is not communicated with the isolation of drive axle inner cavity, and the lubricating oil in retarder cannot be in retarder
It is flowed between chamber and drive axle inner cavity, to realize retarder independent lubricating.
The utility model is to realize that the technical solution of its purpose is such that tectonic forcing bridge front end retarder independent lubricating
Structure, including drive axle and front end retarder, the shell of the front end retarder are fixedly connected with the bracket of the drive axle, institute
The output shaft end face for stating front end retarder sets inner hole, and the inner hole is equipped with and the active spiral bevel gear shaft of drive axle flower
The internal spline of key connection, output shaft outer circumference surface and the output shaft on the reducer shell of the front end retarder stretch out hole
There is the gap of connection reducing gearbox inner cavity, it is characterised in that subtract with described between hole wall in the output shaft of the front end retarder
Output shaft, which stretches out, on fast device shell is provided with what isolation reducing gearbox inner cavity was connected to by the gap with outside between the hole wall of hole
Oil sealing.In the present invention, retarder inner cavity in front end completely cuts off reducing gearbox inner cavity by the gap by oil sealing and drives
Bridge inner cavity is connected to, and the lubricating oil in retarder cannot flow into drive axle inner cavity by gap, to realize that machine subtracts when going up a slope
There is fast device enough lubricating oil to be lubricated to internal transmission part and seal member.Further, the oil sealing setting exists
Output shaft stretches out the end in hole and the end adjacent driving bridge.The oil sealing is lip-shaped sealed ring and lip towards the drive axle
Direction.
Compared with prior art, in the present invention, front end retarder inner cavity is subtracted the utility model by oil sealing isolation
Fast device shell inner cavity is connected to by the gap with drive axle inner cavity, and the lubricating oil in retarder cannot flow into drive axle by gap
Inner cavity, to realize that there is machine retarder when going up a slope enough lubricating oil to moisten to internal transmission part and seal member
It is sliding.
Detailed description of the invention
Fig. 1 is the attachment structure schematic diagram of front end retarder and drive axle in the utility model.
Fig. 2 is the partial enlargement diagram of the junction of front end retarder and drive axle in the utility model.
Parts title and serial number in figure:
Front end retarder 1, sun gear 2, planetary gear 3, internal gear 4, internal tooth wheeling supporting frame 5, oil sealing 6, active screw conic tooth
Take turns 7, drive axle 8, front end reducer shell 9.
Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
As shown in Fig. 1 Fig. 2, drive axle front end retarder independent lubricating structure includes drive axle 8 and front end retarder 1, preceding
There are sun gear 2, planetary gear 3, internal gear 4, internal tooth wheeling supporting frame 5 inside the retarder 1 of end.Before the end of internal tooth wheeling supporting frame 5 is
The output shaft of retarder is held, the output shaft is protruding from the output shaft stretching hole on front end reducer shell 9.Front end retarder
1 output shaft outer circumference surface is stretched out with output shaft has the gap for being connected to reducing gearbox inner cavity between the hole wall in hole, output shaft
End face is provided with inner hole, is equipped with internal spline in inner hole.Front end reducer shell is rigidly fixed with driving abutment bracket and is connect, drive axle
7 shaft of active spiral bevel gear spline connection internal spline, export on the output shaft and reducer shell of front end retarder 1
Axis, which stretches out between the hole wall of hole, is provided with oil sealing 6, which is connected to by gap with outside for completely cutting off reducing gearbox inner cavity.Oil sealing
6 are arranged in end and end adjacent driving bridge that output shaft stretches out hole, are step type in the end end that output shaft stretches out hole
Structure, for installing oil sealing.Oil sealing is lip-shaped sealed ring and lip towards the drive axle direction.
In the present invention, retarder inner cavity in front end completely cuts off reducing gearbox inner cavity by the gap by oil sealing and drives
Dynamic bridge inner cavity is connected to, and the lubricating oil in retarder cannot flow into drive axle inner cavity by gap, to realize machine when going up a slope
There is retarder enough lubricating oil to be lubricated to internal transmission part and seal member.
