Abstract: A disc brake rotor and hub assembly for a heavy-duty vehicle. The disc brake rotor and hub assembly includes a hub portion. The hub portion is receivable on, and rotatable about, an axle spindle of a heavy-duty vehicle. A rotor portion includes a disc segment, a mounting segment and a cylindrical sleeve segment connecting the disc segment to the mounting segment. A flange portion connects with the rotor portion and separately with the hub portion. Optionally, the rotor portion connects directly to the hub portion. A smallest inner dimension of the rotor portion is greater than a largest outer dimension of the hub portion to facilitate removal of the rotor portion without removing the hub portion from the axle spindle.

Abstract: A hub for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body having axially opposite end portions and a longitudinal central axis. Each of a pair of bearing receiving bores is formed in the cylindrical body at a respective axially opposite end portion of the cylindrical body. A circumferential envelope has an outer diameter and is formed on the cylindrical body about one of the pair of bearing receiving bores. A flange extends radially outward from the cylindrical body at a location between the pair of bearing receiving bores. A barrel portion of the cylindrical body extends between the flange and the circumferential envelope and has an outer diameter. The hub provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion 104.
