A hub bearing module for a lightweight suspension upright or knuckle of a vehicle, the hub bearing module including a wheel bearing and a bearing connection interface to the suspension upright or knuckle, the bearing connection interface being arranged coaxial with the rolling bearing and including a first sleeve element and a second sleeve element arranged radially outside the first sleeve element and including a composite, preferably BMC (Bulk Molding Compound) annular body having a radially inner lateral surface mechanically coupled to the first sleeve element and a radially outer lateral surface configured to mechanically and chemically couple with the suspension upright or knuckle.

A seal member is provided in which lip wear is suppressed and resistance to muddy water is increased, as well as a bearing device for a wheel, provided with the seal member. An encoder (63) and an elastic member (65) form a labyrinth section (8) between an outer peripheral surface (61a) of a turned-back section (613) and an inner peripheral surface (64a) of an inner fitting section (641). The labyrinth section (8) extends axially outward and radially outward, and an inner peripheral surface (63c) of the encoder (63) that covers an inner peripheral surface (61c) of the turned-back section (613) is sloped axially inward and radially outward.

The protective cover having a cup shape is mounted to an outer ring of a bearing so as to seal an inward-side end portion of the bearing. A protective cover includes: a disc part made of a synthetic resin; and a sensor holder part that is made of the synthetic resin and protrudes inward from the disc part. The disc part is provided with a separation wall which separates the magnetic encoder and the magnetic sensor from each other. The separation wall has a surface facing the magnetic encoder and a surface facing the magnetic sensor, and one of the surfaces has a mark of a gas drainage pin of an injection molding die.

A steering suspension of a vehicle includes a suspension upright and a mechanical component consisting of a radially outer ring of a wheel hub unit or of a rolling bearing forming part of a wheel hub unit; wherein the outer ring is provided integral in one piece with a flange and a steering arm, extending radially cantilevered from the outer ring and the flange, with which it is also integral in one piece; on the side opposite to the steering arm the flange is provided integral in one piece with a pair of axially drilled radial lugs, configured to support, in use, a brake caliper.

A turbine generator comprises an elongate member, a support structure, a turbine wheel and an electrical generator. The support structure comprises a shaft and supports the elongate member for rotation about a rotation axis. The turbine wheel attached to the elongate member. The electrical generator comprises a rotor and a stator, the rotor being attached to the elongate member and the stator being arranged around the elongate member. The elongate member is provided with a bore and the shaft extends through an end of the elongate member into the bore so as to support it for rotation about the rotation axis.

A propeller assembly of an aircraft includes a hub, a plurality of propeller blades extending from the hub and secured thereto and a propeller blade pitch change system located at at least one propeller blade of the plurality of propeller blades. The propeller blade pitch change system includes a pitch change actuator located in the propeller blade, and a drive mechanism operably connected to the pitch change actuator and to the propeller blade to urge rotation of the propeller blade about a propeller blade axis.

A steering suspension of a vehicle includes a suspension upright and a mechanical component consisting of a radially outer ring of a wheel hub unit or of a rolling bearing forming part of a wheel hub unit. The outer ring is provided integral in one piece with a flange and a steering arm, extending radially cantilevered from the outer ring and the flange, with which it is also integral in one piece. On the side opposite to the steering arm the flange is integral in one piece with a pair of axially drilled radial lugs, configured to support, in use, a brake caliper.

The present invention addresses the problem of providing: a seal member in which lip wear is suppressed and resistance to muddy water is increased; and a bearing device for a wheel, provided with the seal member. An encoder (63) and an elastic member (65) form a labyrinth section (8) between an outer peripheral surface (61a) of a turned-back section (613) and an inner peripheral surface (64a) of an inner fitting section (641). The labyrinth section (8) extends axially outward and radially outward, and an inner peripheral surface (63c) of the encoder (63) that covers an inner peripheral surface (61c) of the turned-back section (613) is sloped axially inward and radially outward.

A supplemental turning function-equipped hub unit includes: a hub unit body including a hub bearing; and a unit support member configured to be mounted through a suspension device, the unit support member supporting the hub unit body through rotation-permitting support components at two upper and lower portions of the hub unit body such that the hub unit body is rotatable about a supplemental turning axis. A supplemental turning force receiving part is provided on a side part of the hub unit body, which part is configured to receive a force that causes the hub unit body to rotate about the supplemental turning axis.

A propeller assembly of an aircraft includes a hub, a plurality of propeller blades extending from the hub and secured thereto and a propeller blade pitch change system located at at least one propeller blade of the plurality of propeller blades. The propeller blade pitch change system includes a pitch change actuator located in the propeller blade, and a drive mechanism operably connected to the pitch change actuator and to the propeller blade to urge rotation of the propeller blade about a propeller blade axis.
