Wheel assembly

An improved wheel assembly for large, off-highway vehicles or the like comprising a wheel having a central non-rotatable housing section and a radially outer rotatable wheel section including a rotatable outer hub and a wheel rim, said assembly comprising:

• drive means mounted on said central housing section for transmitting driving forces to said outer wheel section;
• brake caliper means mounted on said central housing section and disposed radially outwardly from the axis of rotation of said outer wheel section, said caliper means opening radially outwardly from said axis of rotation;
• carrier means mounted on said outer hub section between said central housing section and said wheel rim;
• an annular brake disc supported by said carrier means and operably disposed within and radially outwardly of said brake caliper means, said brake disc having a recess in the outer periphery thereof;
• and
• mounting means for mounting said brake disc to said carrier means for limited relative circumferential movement therebetween, including an annular ring having at least one lug formed integrally therewith and disposed within said recess in said brake disc.

• carrier means mounted on said outer hub section between said central housing section and said wheel rim and including a radially inwardly extending support flange;
• an annular brake disc operably disposed within and radially outwardly of said brake caliper means and supported by said carrier means, said support flange limiting axial movement of said disc in one direction with respect to said carrier means, said brake disc having recesses at the outer periphery thereof;
• holding means affixed to said carrier means for limiting relative axial movement of said disc in the opposite direction;
• and
• at least one lug affixed to said carrier means and disposed in a corresponding recess of said disc,
• whereby said brake disc is mounted for limited movement with respect to said carrier means to permit thermal expansion and contraction of the respective parts.
