Title: HUB FOR HEAVY-DUTY VEHICLE
Abstract:
A hub (100) for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body (102) having axially opposite end portions and a longitudinal central axis (A). Each of a pair of bearing receiving bores (124, 126) is formed in the cylindrical body (102) at a respective axially opposite end portion of the cylindrical body. A circumferential envelope (182) has an outer diameter (D3) and is formed on the cylindrical body (102) about one of the pair of bearing receiving bores (124, 126). A flange (160) extends radially outward from the cylindrical body (102) at a location between the pair of bearing receiving bores (124, 126). A barrel portion (104) of the cylindrical body (102) extends between the flange (160) and the circumferential envelope and has an outer diameter (D2). The hub (100) provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion (104).
