The present invention relates to a wheel hub for vehicle axle used in trucks, buses, trailers and semi-trailers, consists of a cylindrical central body, said central body surrounded by a plurality of radial projections extending vertically from the median region of said central body, being structured by ribs integrated with said projections providing robustness, reduced weight and reduced heat transfer from the brake to tires.

A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.

The invention relates to a wheel for a powered two-wheeler, in particular a motorcycle or a motor scooter, that is at least sectionally made of a fiber-reinforced plastic material. A hub area (12) of the wheel (IO) is provided with two rigid, self-supporting, metal inserts (18, 20), which are arranged on axially opposite sides of the hub area (12), and which in an axial and radial direction (A, r) are connected to one another in a form-fit manner.

A hub-bearing unit is provided with: a rotatable hub, with an axially outer flange portion configured for engagement with a rotatable element of a motor vehicle, a bearing unit provided with a fixed radially outer ring, configured for engagement with a fixed element of the motor vehicle, a first, axially outer, crown of rolling bodies, and a second, axially inner, crown of rolling bodies, interposed between the radially outer ring and the hub. The hub also assumes the function of the radially inner ring of the bearing unit and the bell of a constant velocity joint. The hub-bearing unit is designed so that the axial distance between the center of the axially inner crown of rolling bodies and the rolling center of the constant velocity joint lies within a predetermined range according to the following formula:

[00001]$\{\begin{array}{cc}\mathrm{with}.Math..Math.L\ge 0,& 0.4\le \frac{P_B}{S+A+L}\le 4\\ \mathrm{with}.Math..Math.L<0,& 0.5\le \frac{P_B}{S+A}\le 4.Math.\end{array}\hspace{1em}$

A hub-bearing unit is provided with a hub, rotatable, with an axially outer flange portion configured for engagement with a rotatable element of a motor vehicle, a bearing unit provided with a fixed radially outer ring, configured for engagement with a fixed element of the motor vehicle, a first, axially outer, crown of rolling bodies, and a second, axially inner, crown of rolling bodies, interposed between the radially outer ring and the hub. The radially outer ring is held in position with respect to the knuckle by a stop ring, positioned on the axially inner side of the radially outer ring in a seat formed on the radially outer ring.

A braking structure for an in-wheel motor drive device includes: an in-wheel motor drive device including a wheel hub bearing unit (11) and a motor unit, the wheel hub bearing unit (11) including an outer ring (12) connected to a road wheel (W) and a brake rotor (BR), inner rings (13) disposed coaxially with the outer ring (12), and a plurality of rolling elements (14) arranged in annular clearance between the outer ring and the inner rings, and the motor unit being configured to drive the outer ring; a carrier member (17) coupled to a vehicle body-side member and attached to and fixed to an inner fixing member (15) for the inner rings (13); and a brake caliper bracket (18) that has its inner end (18b) connected to the carrier member (17) and that supports a brake caliper (19) at its outer end (18a).

A wheel bearing assembly includes at least one hub having an axial outboard end, a first bearing installed in the hub and having an outer ring and an inner ring, and at least one seal element that seals against a radially inner surface of the first bearing inner ring in a liquid-tight manner. The first bearing is the outboard-most bearing of the wheel bearing assembly.

A wheel end assembly having a spindle, a hub, and a rotary seal assembly. The spindle defines a spindle air passage, a vent passage, and a spindle hole. The hub defines a hub air passage. The rotary seal assembly fluidly connects the spindle air passage to the hub air passage. The vent passage fluidly connects an inboard cavity to the spindle hole.

A face seal for use within a wheel assembly may include an inner sealing ring and an outer sealing ring. The outer sealing ring may include a first flange, a second flange and an outer cylindrical portion extending between the first and second flanges. The outer cylindrical portion may include a first cylindrical section extending axially from the first flange and a second cylindrical section extending axially between the first cylindrical section and the second flange. The face seal may also include an inner elastomeric ring and an outer elastomeric ring having an axial portion extending radially outwardly from the second cylindrical section of the outer cylindrical portion. Additionally, the axial portion may be radially offset from the first cylindrical section of the outer cylindrical portion such that an outer surface of the first cylindrical section is spaced radially outwardly relative to an outer surface of the axial portion.

A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.
