Title: Track shoe or track pad having a wear member
Inventor: RATHOD CHANDRASEN R
IPC: B62D55/28
Filed: 2021-06-16
Abstract: Claims 
1. A track shoe, comprising: 
a base plate; 
a grouser extending from the base plate, wherein at least a portion of the grouser 
includes a substantially martensitic structure; and 
at least one white iron member, wherein the at least one white iron member is 
fixed to a portion of the grouser.  
2. The track shoe of claim 1, wherein the grouser extends from the base plate 
and includes a distal end surface, wherein the white iron member is coupled to the distal end 
surface of the grouser.  
3. The track shoe of claim 2, wherein the distal end surface includes at least 
one flat portion, and wherein the at least one white iron member is coupled to the at least one flat 
portion.  
4. The track shoe of claim 3, wherein the at least one white iron member is 
brazed to the distal end surface.  
5. The track shoe of claim 2, wherein the grouser includes a base portion that 
is wider than the distal end surface, and wherein the at least one white iron member includes a 
base portion and a distal end surface that is narrower than the base portion of the at least one 
white iron member.  
6. The track shoe of claim 5, wherein the grouser is formed of a steel, and 
wherein at least the distal end surface of the grouser is carburized.  
7. The track shoe of claim 1, wherein at least a portion of the least one white 
iron member includes a substantially carbide structure, and wherein the portion of the at least one
-17
white iron member that includes the substantially carbide structure is fixed to the portion of the 
grouser that includes the substantially martensitic structure.  
8. The track shoe of claim 1, wherein the at least one white iron member 
includes a plurality of white iron members, wherein the plurality of white iron members are 
longitudinally spaced apart on a distal end surface of the grouser.  
9. The track shoe of claim 8, wherein at least one white iron member is a 
different size than at least one other of the plurality of white iron members.  
10. The track shoe of claim 1, wherein the at least one white iron member 
includes a rounded distal end surface.  
11. A method of producing a track shoe, comprising: 
fixing at least one white iron member to an outer surface of a grouser, wherein the 
at least one white iron member includes a flat base portion, and wherein the grouser includes a 
flat outer edge portion.  
12. The method of claim 11, wherein the fixing the at least one white iron 
member includes brazing the at least one white iron member to the grouser.  
13. The method of claim 12, further comprising carburizing at least a portion 
of the grouser either before or after brazing the at least one white iron member to the grouser.  
14. The method of claim 12, further comprising quenching the track shoe after 
brazing the at least one white iron member to the grouser, such that at least a portion of the at 
least one white iron member includes a substantially carbide structure and at least a portion of 
the grouser includes a substantially martensitic structure.  
15. The method of claim 11, wherein the white iron member includes a 
plurality of white iron members.
-18
16. A method of producing a track pad, comprising: 
fixing at least one white iron member to an outer surface of the track pad, wherein 
the at least one white iron member includes a flat base portion, and wherein the track pad 
includes a flat ground side portion.  
17. The method of claim 16, wherein the fixing the at least one white iron 
member includes brazing the at least one white iron member to the track pad.  
18. The method of claim 17, further comprising carburizing at least a portion 
of the track pad either before or after brazing the at least one white iron member to the track pad.  
19. The method of claim 17, further comprising quenching the track pad after 
brazing the at least one white iron member to the track pad, such that at least a portion of the at 
least one white iron member includes a substantially carbide structure and at least a portion of 
the track pad includes a substantially martensitic structure.  
20. The method of claim 16, wherein the white iron member includes a 
plurality of white iron members.
