Brake disc mounting arrangement

A method for assembling an adjustable brake disc mounting arrangement on an axle hub, the axle hub having a rotation axis, comprising the acts of:

• locating a brake disc mounting adapter on the axle hub, the brake disc mounting adapter having a plurality of wedge-shaped brake disc mounting keys;
• locating a brake disc on the brake disc mounting adapter, the brake disc having a plurality of wedge-shaped slots circumferentially around a radially inner region of the brake disc, the wedge-shaped slots being configured to be received on corresponding ones of the brake disc mounting adapter keys when the brake disc is in an installed position on the brake disc mounting adapter;
• locating a brake disc retainer over the plurality of wedge-shaped slots of the brake disc;
• fixing the brake disc retainer on the brake disc mounting adapter with a plurality of retaining fasteners such that the brake disc is axially retained on the brake disc mounting adapter;
• adjusting an axial position of the brake disc mounting adapter relative to the axle hub along the rotation axis;
• and
• fixing the axial position of the brake disc mounting adapter relative to the axle hub.

A method for assembling an adjustable brake disc mounting arrangement on an axle hub, the axle hub having a rotation axis, comprising the acts of:

• locating a plurality of lead screws on an adapter base, the adapter base having apertures configured to receive at least one of hub-mounted fasteners and fasteners configured to be received in apertures of the axle hub are passable to fix the adapter base to the axle hub;
• locating the adapter base on the axle hub;
• locating on each of the plurality of leadscrews a corresponding one of a plurality of threaded collars;
• locating a brake disc mounting adapter on the plurality of threaded collars, the brake disc mounting adapter having a plurality of wedge-shaped brake disc mounting keys;
• adjusting an axial position of the brake disc mounting adapter relative to the axle hub along the rotation axis by rotating the plurality of threaded collars on the plurality of leadscrews;
• fixing axial positions of the plurality of threaded collars on the plurality of lead screws;
• either before or after the act of adjusting the axial position of the brake disc mounting adapter, locating a brake disc on the brake disc mounting adapter, the brake disc having a plurality of wedge-shaped slots circumferentially around a radially inner region of the brake disc, the wedge-shaped slots being configured to be received on corresponding ones of the brake disc mounting adapter keys when the brake disc is in an installed position on the brake disc mounting adapter;
• locating a brake disc retainer over the plurality of wedge-shaped slots of the brake disc;
• and
• fixing the brake disc retainer on the brake disc mounting adapter with a plurality of retaining fasteners such that the brake disc is axially retained on the brake disc mounting adapter.
