Bearing for wheel mount
First Claim
1. A wheel mount comprisingan outer ring for defining the outer races of two rows of bearing rolling elements;
- an axially more inward axle journal having an exterior periphery which defines a first inner race for one of the rows of rolling elements and cooperating with a respective first one of the outer races defined inside the outer ring;
axially outward of the first inner race, a separate inner ring having an external periphery with a second inner race defined thereon for cooperating with a respective second one of the outer races on the interior of the outer ring for the second row of rolling elements;
The separate inner ring having an axially inner end which is axially pressed against the axle journal;
the separate inner ring having an internal bore, and the axle journal including a pin which is generally complementary in shape to the internal bore of the inner ring and projects through the internal bore;
the separate inner ring having a radially widened region at the axially more outward region thereof, and the internal bore of the separate ring having the smallest diameter at the widened region;
axially inward of the widened region, the internal bore having defined in it a plurality of steps of gradually greater diameter from step to step axially inward, and the axle journal having cooperating, correspondingly shaped steps defined on it shaped for force fitting the inner ring on the correspondingly shaped axle journal.

Abstract
A wheel mount for motor vehicles or the like. An axially inner hub having an axle journal which projects axially outwardly and a first row of ball bearings rolling about the axle journal. A separate inner ring axially outward of the axle journal and having a second row of ball bearings rolling about it. The separate inner ring having a radially widened region on the axially outward side. The internal bore of the separate inner ring progressing from a radially smaller diameter at the widened region over a plurality of steps which have gradually greater inner diameters. The axle journal on the hub extends through the inner ring and has correspondingly shaped steps. The inner ring is force fit over the axle journal. A radially outwardly bulging bead presses on the axially outward end of the separate inner ring and presses that ring against a shoulder of the axle journal.
