Motor vehicle wheel assembly

A motor vehicle drive wheel assembly, comprising:

• a fixed sub-assembly comprising a first annular outer raceway and a second annular outer raceway centered on an axis of rotation;
• a rotating subassembly, capable of rotating relative to the fixed subassembly about the axis of rotation, and comprising a wheel hub comprising a flange provided with an interface for attaching a wheel rim or a brake disc, the attachment flange forming a mounting face of the wheel rim or of the brake disc axially facing in a direction of disassembly of the wheel rim or of the brake disc, the direction of disassembly being parallel to the axis of rotation, a transmission bowl, and at least one inner rolling bearing ring, the at least one inner rolling bearing ring being shrink-fitted onto a shrink-fit surface of the wheel hub, the at least one inner rolling bearing ring having a contact face facing axially in the opposite direction to the direction of disassembly, bearing against the transmission bowl at an annular contact interface, the at least one inner rolling bearing ring having an end face facing axially in the direction of disassembly, bearing against a shoulder of the wheel hub along a bearing interface having an outer circumference with a diameter DCE, the rotating subassembly further comprising a first inner raceway located opposite the first outer raceway and a second inner raceway located opposite the second outer raceway and formed on the at least one inner rolling bearing ring;
• and
• balls, forming a first row of balls having a ball diameter DB1 and capable of rolling on the first outer raceway and the first inner raceway and a second row of balls having a ball diameter DB2 and capable of rolling on the second outer raceway and the second inner raceway, the centers of the balls of the first row of balls being located on a pitch circle of diameter DP1 located in a first pitch plane, the centers of the balls of the second row of balls being located on a pitch circle of diameter DP2 located in a second pitch plane, the first pitch plane being located at a non-zero distance L from the second pitch plane in the direction of disassembly, the end face being located axially between the first pitch plane and the second pitch plane;
• wherein the end face of the at least one inner rolling bearing ring is located at a distance from the first pitch plane greater than half of the ball diameter DB1 of the balls of the first row of balls and in that the relationship:
