DRIVE SECTION FOR USE IN A BEARING ARRANGEMENT

摘要

The invention relates to a drive section (2) for use in a bearing arrangement (1) of a driven vehicle wheel end, especially of a truck or trailer, wherein the drive section (2) comprises at least one inner raceway (10, 11) for rolling elements (22, 23), wherein the drive section (2) is arranged to be connected at one axial end (3) at an outboard side (15) with a hub element (4) and is arranged to be connected at the other axial end (5) distal from the outboard side (15) with a drive element (6) and wherein the drive section (2) has a center bore (7), which extends through the whole drive section (2) from one axial end (3) to the other axial end (5). To facilitate the assembly and disassembly of the vehicle wheel end, the invention is characterized in that the center bore (7) in the drive section (2) has a first bore section (12) and a second bore section (13), wherein the diameter (d) of the first bore section (12) is smaller than the diameter (D) of the second bore section (13) and wherein the bore section (13) with the greater diameter (D) is arranged adjacent to the outboard side (15) of the hub element (4).
