A train axle assembly includes a train axle, a ring assembly coaxially mounted on the train axle and a structure operatively engaged by the ring assembly and mounted on the train axle. The ring assembly has an outer diameter and a main section adjacent the outer diameter. The ring assembly includes a projection extending axially from the main section which is located at a diameter less than the outer diameter of the ring assembly. The projection has a portion of a diameter contacting the train axle so that the ring assembly is affixed to the train axle to provide resistance to relative rotation and axial movement between the ring assembly and the train axial.

대표청구항 ▼

1. A train axle assembly comprising: a train axle;a ring assembly coaxially mounted on said train axle, said ring assembly having a main section comprising a radially outer surface with a substantially constant outer diameter, said ring assembly comprising:a projection extending axially from said main section, said projection having a radially inner surface located at a diameter less than said outer diameter of said main section;said radially inner surface contacting said train axle wherein said ring assembly affixed to said train axle provides resistance to relative rotational and axial movement between said ring assembly and said train axle;said main section having a connecting portion extending continuously in a radial direction from said radially outer surface to a point where said projection extends from said main section;said main section and said projection bounding a cavity, said cavity extending at least partially in an axial direction such that said main section extends in an axial direction less than said projection extends in said axial direction;said main section having a lateral portion extending continuously in the radial direction from said radially outer surface to said cavity; anda structure operatively engaged by said ring assembly and mounted on said train axle. 2. The train axle assembly of claim 1 wherein said cavity extends an entire circumferential length of said ring assembly. 3. The train axle assembly of claim 1 wherein said structure operatively engaged by said ring assembly comprises a bearing housing, a backing plate, a ring or a housing. 4. The train axle assembly of claim 1 wherein said radially inner surface of said ring assembly has a diameter less than an outside diameter of said train axle. 5. The train axle assembly of claim 4 wherein the cavity of said ring assembly is deformed. 6. The train axle assembly of claim 5 wherein said ring assembly comprises a ring shape. 7. The train axle assembly of claim 1 wherein said cavity extends at least partially in said radial direction. 8. The train axle assembly of claim 1 wherein said projection deflects in response to a load. 9. A method of assembling a train axle assembly comprising: providing a train axle;coaxially mounting a ring assembly on said train axle, said ring assembly having a main section comprising a radially outer surface with a substantially constant outer diameter, said ring assembly comprising: a projection extending axially from said main section, said projection having a radially inner surface located at a diameter less than said outer diameter of said main section;said radially inner surface contacting said train axle wherein said ring assembly affixed to said train axle provides resistance to relative rotational and axial movement between said ring assembly and said train axle;said main section having a connecting portion extending continuously in a radial direction from said radially outer surface to a point where said projection extends from said main section;said main section and said projection bounding a cavity, said cavity extending at least partially in an axial direction such that said main section extends in an axial direction less than said projection extends in said axial direction;the main section having a lateral portion extending continuously in the radial direction from the radially outer surface to the cavity;mounting a structure on said train axle and operatively engaging said structure by said ring assembly. 10. The method of claim 9 wherein said cavity extends an entire circumferential length of said ring assembly. 11. The method of claim 9 wherein said structure comprises a bearing housing, a backing plate, a ring or a housing. 12. The method of claim 9 wherein said radially inner surface of said ring assembly has a diameter less than an outside diameter of said train axle. 13. The method of claim 9 further comprising deforming the cavity of said ring assembly. 14. The method of claim 9 wherein said ring assembly comprises a ring shape. 15. The method of claim 9 wherein said cavity extends at least partially in said radial direction. 16. The method of claim 9 further comprising said projection deflecting in response to a load. 17. The method of claim 9 further comprising said projection deflecting in response to a load in said radial direction.
