In foretell motor wheel hub lid, the outer terminal surface of wheel hub lid extends outward and is formed with the axle sleeve body, the motor shaft hole is seted up on the axis of the axle sleeve body, and the lateral wall of the axle sleeve body personally submits the stair structure, and preceding including minor diameter portion and major diameter portion after to in proper order, be formed with between minor diameter portion and the major diameter portion with the tank bottom surface position of storage tank inside and outside relative step face, be provided with outer processing arch on the step face, outer processing arch and wheel hub lid formula structure as an organic whole, and outer processing arch is formed by inside turning step face.

In the above-mentioned motor hub cover, the outer processing arch comprises a plurality of processing trench that the step face inwards caves in, and the processing trench is evenly distributed around the axis circumference in motor shaft hole.

In the above-mentioned motor wheel hub cover, the processing trench is circular arc structure.

Compared with the prior art, the utility model outstanding advantage is:

the utility model has the advantages of simple structure and reasonable design, it is protruding in order to form to process through reducing the lathe work face to the storage tank, increase the machining allowance to effectively avoid taking place because of the produced bubble of pouring and leading to gas leakage, the phenomenon of oil leak when lathe work, simultaneously, the support intensity of wheel hub lid can further be improved to interior processing arch.

fig. 3 is a first perspective view of a second embodiment of the present invention;

fig. 4 is a second perspective view of a second embodiment of the present invention;

fig. 5 is a sectional view of a second embodiment of the present invention.

In the figure: 1. a hub cover; 2. a motor shaft hole; 3. a containing groove; 4. internally processing a bulge; 5. a shaft sleeve body; 6. a small diameter part; 7. a large diameter portion; 8. externally processing a bulge; 9. and (6) processing the groove position.

The specific implementation mode is as follows:

the invention will now be further described with reference to specific embodiments, with reference to figures 1 to 5:

the first embodiment is as follows:

the utility model provides a motor wheel hub lid, including wheel hub lid 1 and set up on wheel hub lid 1 and motor shaft hole 2 that the power supply machine pivot runs through, the interior port department of motor shaft hole 2 sets up the storage tank 3 that supplies the bearing to pack into, be provided with interior processing arch 4 on the tank bottom surface of storage tank 3, interior processing arch 4 and wheel hub lid 1 formula structure as an organic whole, and interior processing arch 4 is formed by the tank bottom surface of outside turning storage tank 3.

Namely the utility model has the advantages of simple structure and reasonable design, through reduce to storage tank 3 the lathe work face, increase the processing surplus in order to form processing arch 4 to effectively avoid taking place because of the produced bubble of pouring and leading to gas leakage, the phenomenon of oil leak in lathe work, simultaneously, the support intensity of wheel hub lid 1 can also further be improved to the protruding 4 of interior processing.

Meanwhile, the structure of the inner processing protrusion 4 may be an annular or irregular structure, which is determined according to actual requirements, and in this embodiment, the structure and distribution positions adopted by the inner processing protrusion 4 are as follows: interior processing arch 4 is fast column structure, and its axis circumference equipartition around motor shaft hole 2 has a plurality of.

According to the research of practical production and use, the phenomenon that air leakage and oil leakage occur between the bottom surface of the accommodating groove 3 and the side wall of the groove due to bubbles generated by pouring is the most likely to occur, so the inner processing bulge 4 is arranged between the bottom surface of the accommodating groove 3 and the side wall of the groove.

Example two:

the structure of this embodiment is substantially the same as that of the first embodiment, and the main difference is that: the outer terminal surface of wheel hub lid 1 outwards extends and is formed with the axle sleeve body 5, motor shaft hole 2 is seted up on the axis of axle sleeve body 5, and the lateral wall of axle sleeve body 5 personally submits the stair structure, and preceding including minor diameter portion 6 and major diameter portion 7 after to in proper order, be formed with between minor diameter portion 6 and the major diameter portion 7 with the tank bottom surface position of storage tank 3 inside and outside relative step face, be provided with the protruding 8 of outer processing on the step face, the protruding 8 of outer processing and 1 formula structure as an organic whole of wheel hub lid, and the protruding 8 of outer processing is formed by inside turning step face. Namely, the outer processing bulge 8 is also machined on the step surface corresponding to the accommodating groove 3, so that the phenomena of air leakage and oil leakage caused by air bubbles generated by casting during turning can be further avoided.

Meanwhile, the outer processing protrusion 8 may have the same structure as the inner processing protrusion 4, and in the present embodiment, the outer processing protrusion 8 has the following specific structure: the outer processing bulge 8 is composed of a plurality of processing groove positions 9 with stepped surfaces inwards sunken, and the processing groove positions 9 are uniformly distributed around the axis of the motor shaft hole 2 in the circumferential direction. Furthermore, the processing slot 9 is in a circular arc structure.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: all equivalent changes made according to the shape, structure and principle of the utility model are covered within the protection scope of the utility model.
