Hub-bearing assembly for a driving wheel of a vehicle, particularly a truck

摘要

An annular hub (11) has flange (2) for connecting to a wheel and an axial cylindrical surface (14) for mounting a bearing unit (7). An intermediate annular member (30) is coupled for rotation to a driving axle shaft (1) by a first toothed/splined coupling (21, 31) and to the hub (11) by a second toothed/splined coupling (22, 32).
