Abstract
An axle assembly and a method of assembly. An outboard wheel is mounted to an outboard mounting arrangement of a wheel hub. An inboard wheel and a brake drum are mounted to an inboard mounting arrangement of the wheel hub such that a brake drum mounting arrangement of the brake drum is axially positioned between the inboard wheel and the inboard mounting arrangement.
Claims20
An axle assembly comprising:
- a wheel hub that is rotatable about an axis and that comprises an outboard mounting arrangement that extends away from the axis and an inboard mounting arrangement that extends away from the axis and is spaced apart from the outboard mounting arrangement, wherein the outboard mounting arrangement includes a plurality of outboard mounting flanges that are spaced apart from each other, arranged around the axis in an outboard plane, and extend away from the axis;
- an outboard wheel that is mounted to the outboard mounting arrangement;
- an inboard wheel that is spaced apart from the outboard wheel and that is mounted to the inboard mounting arrangement that comprises inboard wheel mounting flanges;
- and
- a brake drum that is received inside the inboard wheel and that comprises a brake drum mounting arrangement that is mounted to the inboard mounting arrangement such that the brake drum mounting arrangement is axially positioned between the inboard wheel and the inboard mounting arrangement, wherein the brake drum includes a plurality of brake drum mounting flanges that are spaced apart from each other and extend toward the axis, wherein a gap is provided between each adjacent pair of outboard mounting flanges that is larger than the brake drum mounting flange such that each brake drum mounting flange is fittable between a pair of adjacent outboard mounting flanges, and wherein the outboard mounting flanges are fittable between adjacent pairs of brake drum mounting flanges and are fittable between adjacent pairs of inboard wheel mounting flanges.
