Abstract
A hub bearing unit assembly having an inner and outer race ring, which being unified with a fastening flange, with rows of rolling elements located between the races, said rolling elements being separated from one another by means of a cage, as well as comprising seals, which retain a lubricant contained between the rolling elements, the bearing parts being connected to a shaft or part of a shaft, wherein the end part of the inner race opposite the flange section and situated outside the inner side of said race ring, the so-called head section, comprises coupling elements by means of which the race is connected to the shaft or a part of it so as to transmit power.

In a hub bearing unit assembly having an inner and outer race ring, each having unified therewith a fastening flange, rows of rolling elements located between said races, said rolling elements being separated from one another by means of a cage, said inner and outer race having seals coupled thereto, said seals acting to retain a lubricant contained between the rolling elements, and a driving shaft, the improvement comprising the end part head section of said inner race opposite its respective flange section and situated outside the inner side of said race ring having formed thereon coupling means, adapted to be coupled to said driving shaft and, by means of which coupling means said inner race is connected to said shaft so as to transmit power to said inner race, the inner side of said inner race facing said shaft in a nonpower transmissible manner.
A hub bearing and drive shaft assembly comprising a rotatable drive shaft, a bearing including a flange inner race and a flanged outer race separated by a plurality of caged rolling elements and sealed for the containment of lubricant, said inner race having a head section including a first plurality of coupling elements positioned to face outward from said inner race in a direction paralleling the axis about which said shaft rotates, said shaft including a further plurality of coupling elements positioned thereon so as to be engageable in a power transmissible manner with said first plurality of coupling elements for providing an axially directed power coupling between said shaft and said inner race.
