Abstract
A wheel bearing including at least one inner ring. In order to achieve a greater efficiency, the inner ring forms an outer ring of a tripod constant-velocity joint. The wheel bearing may further include an outer ring and two rolling-element rows including a first rolling-element row and a second rolling-element row.
Claims16
A wheel bearing comprising:
- at least one inner ring,
- wherein the at least one inner ring is configured to form an outer ring of a tripod constant-velocity joint such that three axially extending openings emanate from a hollow-cylindrical base shape, wherein each axially extending opening is bordered circumferentially by one of the at least one raceway of the tripod constant-velocity joint, wherein the outer ring of the constant-velocity joint comprises at least one raceway,
- wherein the wheel bearing further comprises two rolling-element rows, and at least 30% of a maximum axial extension length of the at least one raceway of the outer ring of the constant-velocity joint is disposed axially between the rolling-element rows of the wheel bearing.
A wheel bearing comprising:
- at least one inner ring,
- wherein the at least one inner ring is configured to form an outer ring of a tripod constant-velocity joint such that three axially extending openings emanate from a hollow-cylindrical base shape, wherein each axially extending opening is bordered circumferentially by one of the at least one raceway of the tripod constant-velocity joint, wherein the wheel bearing further comprises two rolling-element rows;
- and wherein at least 30% of a maximum axial extension length of a raceway of the outer ring of the tripod constant-velocity joint is disposed axially between the rolling-element rows of the wheel bearing, wherein an axial center point of the raceway of the outer ring of the tripod constant-velocity joint is axially spaced from an axial center of the two rolling-element rows by less than 50% of a spacing between the two rolling-element rows of the wheel bearing, wherein the at least one inner ring and at least one of a rim receiving region and a rim locking flange are inseparably configured.
A wheel bearing comprising:
- at least one inner ring,
- wherein the at least one inner ring is configured to form an outer ring of a constant-velocity joint, wherein the outer ring of the constant-velocity joint comprises at least one raceway,
- wherein the wheel bearing further comprises two rolling-element rows, and at least 30% of a maximum axial extension length of the at least one raceway of the outer ring of the constant-velocity joint is disposed axially between the rolling-element rows of the wheel bearing;
- wherein the at least one inner ring and at least one of a rim receiving region and a rim locking flange are inseparably configured;
- wherein the inner ring further comprises an inner region disposed axially between the at least one raceway and the locking flange, wherein the inner region is disposed radially farther outward than the at least one raceway.
