A hub-bearing unit includes a bearing unit having a stationary radially outer ring, a rotatable radially inner ring, and a double row of rolling bodies. The first row of rolling bodies, are axially outwards, interposed between the radially outer ring and a rotor-hub. The rolling bodies centers are located along a radius of a first circle, respective to a hub-bearing unit symmetry axis. The second row of rolling bodies, axially inwards, being interposed between the radially outer ring and the radially inner ring. The radially inner ring is assembled on top of the rotatable rotor-hub. A flange portion is axially external and steadily fixed to a tubular portion of the rotor-hub. The flange includes a plurality of fixing holes, whose axes are located along a radius of a second circle, respective to the hub-bearing unit symmetry axis. The first circle radius is greater than the second circle radius.

A wheel hub rotary joint assembly includes a wheel hub with a wheel flange and a sleeve section for receiving a wheel bearing; and a constant-velocity rotary joint with an outer joint part having a first spur gearing section with first teeth at its end facing the wheel hub. The sleeve section has a second spur gearing section with second teeth at its end facing the rotary joint. The two spur gearing sections engage one another for torque transmission. At least one of the two spur gearing sections is designed such that, viewed in the radial direction, the first and second teeth initially only come into contact with one another on a small subsurface of the tooth surfaces facing one another during axial tensioning. Viewed in the radial direction, the first and second teeth initially come only into contact with one another on the radially inward side and, as tensioning increases, also come into contact with one another on the radially outward side, for which purpose a substructure of the sleeve section and/or of the outer joint part having the teeth is more easily deformable in a radially inward region than in a region lying radially further outward.

A rotary ring of a hub unit has an annular first end face on one side in the axial direction, and an outer ring of a joint has an annular second end face on the other side in the axial direction. Outer splines are formed in a radially outer-side region of the first end face and outer splines are formed in a radially outer-side region of the second end face. The outer splines of the first end face and the outer splines of the second end face mesh with each other. Inner splines are formed in a radially inner-side region of the first end face and inner splines are formed in a radially inner-side region of the second end face. The inner splines of the first end face and the inner splines of the second end face mesh with each other.

A wheel bearing apparatus has a double row rolling bearing detachably united with a constant velocity universal joint. The double row rolling bearing has an outer member, an inner member, and double row rolling elements rollably disposed between the double row raceway surfaces of the outer member and inner member. The constant velocity universal joint has an outer joint member, a shoulder portion, and a shaft portion. A female thread is formed on the shaft portion. End faces of the shoulder portion and the caulked portion are formed with face splines, respectively. The face spline of the caulked portion has a portion where a tooth height of a tooth space of a portion radially outside the pitch circle diameter is set lower than that of other portions of the tooth space.
摘要:
A static sealing device for a wheel hub assembly, an inner ring operatively associated with a constant velocity joint, an outer ring coupled with the wheel hub, including a first sealing assembly arranged between the inner ring and an outer ring for protecting respective rolling bodies, and a second sealing assembly integrally carried by the inner ring, arranged straddling the wheel hub and the outer ring of the joint; wherein the first sealing assembly includes a shield anchored to the inner ring of the bearing and provided, on the first side of the joint, with a flange portion carrying an annular signal generating element towards the joint which leaves an annular radially inner area of the flange portion uncovered, defining an annular seat between it and the inner ring in which an edge radially folded on the outside of a tubular core of the second sealing assembly is coupled.
摘要:
Splines, which are to be meshed with a joint that transmits torque to a rotary ring of a hub unit, are formed in a side face of the rotary ring, the side face being on one side of the rotary ring in the axial direction. Spline grooves are formed in the side face by subjecting the side face to broaching.
摘要:
A wheel bearing device includes a hub ring, a double-row bearing and a constant velocity universal joint which are unitized together. At least one of double-row inner raceways of the bearing and a wheel mounting flange are formed on a hub ring. The hub ring and a stem portion of a joint outer ring of the constant velocity universal joint are fitted through a torque transmission assembly, wherein a pilot member as a separate element having a wheel guide portion and a brake guide portion is fitted to a side-end portion of the wheel mounting flange of the hub ring, and the hub ring and the pilot member are fixed to the joint outer ring by swaging.

A wheel bearing device having a unitized hub ring, double-row bearing and constant velocity universal joint with one of double-row inner raceways formed on the joint outer ring. An end portion of the joint outer ring is fitted to an outside periphery of the hub ring through serrated portions. The hub ring is plastically deformed and expanded from an inside diameter side toward an outside diameter side by pushing a steel ball into a through hole of the hub ring preventing play in the serrated portions by the diameter expansion. A surface-hardened layer is formed at least on a base portion of the wheel mounting flange.
