The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
In the description of the present invention, it is to be understood that term " on ", " under ", " " center ", " interior ", " outer ", " top ",
The orientation or position relationship of instructions such as " bottoms " are based on orientation shown in the drawings or position relationship, are for only for ease of and describe this hair
It is bright to have specific orientation, with the device for simplifying description rather than instruction or hint meaning or element with specific orientation
Construction and operation, therefore be not considered as limiting the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or be integrally connected；It can
To be mechanical connection or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary, Ke Yishi
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
As shown in Figure 1, the present invention provides a kind of Tractor Driving Axle, including seal protection component 1, the seal protection portion
Part 1 is arranged on the bridge tube of drive axle and link position of the side transmission housing at float grease seal position, the seal protection component 1
It is set on the outside of the float grease seal, 1 side of seal protection component is embedded on the bridge tube end face, the seal protection
1 another side end face of component can release formula overlap joint with the side transmission housing end face.In this way, it is floating in bridge tube and side transmission housing
Link position setting seal protection component 1 at oil sealing position, it is floating that seal protection component 1 can effectively stop that mud grass is in direct contact
Dynamic oil sealing improves the service life of float grease seal；And 1 side of seal protection component is embedded on bridge tube end face, seal protection
1 another side end face of component can release formula overlap joint with side transmission housing end face so that entire seal protection component 1 can be to the oil that floats
When sealing and carry out closed protection, and then realizing that drive axle works in muddy water environment, prevent water plant or other impurities directly with floating
Dynamic oil sealing contact, reduces float grease seal market failure rate, improves the service life of float grease seal.Have in terms of existing technologies
It has the advantage that：Float grease seal market failure rate is reduced, improves the service life of float grease seal.
The Tractor Driving Axle of the present invention, as shown in Figure 1, can also be on the basis of the technical solution described in front：
The seal protection component 1 includes sealing 11 and friction portion 12, and the sealing 11 is fixedly connected with the friction portion 12, institute
It states sealing 11 to be embedded on the bridge tube end face, 12 end face of friction portion can release formula with the side transmission housing end face and take
It connects.In this way, sealing 11 is embedded on bridge tube end face, 12 end face of friction portion can release formula overlap joint with side transmission housing end face, make
Gap between bridge tube end face and side transmission housing end face is blocked by sealing 11 and friction portion 12, realize blocking water plant and miscellaneous
The effect of object since friction portion 12 is when side transmission housing rotates, with side transmission housing frictional connection, is prevented in side transmission housing
Sealing 11 and the structure in friction portion 12 are damaged during rotation.Further preferred technical solution is：The sealing 11 is by butyronitrile
