A hub structure having an anti-lock braking system contains: a hub assembly and an anti-locking assembly. The hub assembly is located on a center of a wheel and includes a holder and a connection shaft. The anti-locking assembly is received in the holder and is fitted on the connection shaft, and the anti-locking assembly includes an anti-lock seat received in the holder and fitted on the connection shaft to rotate with the holder simultaneously, multiple eddy current elements arranged on two sides of the anti-lock seat and two ends of the connection shaft. A predetermined distance is defined between any two adjacent eddy current elements, and a respective eddy current element has at least one electromagnetic induction portion, when two corresponding electromagnetic induction portions are electrically conducted, a current magnetic field produces so that the anti-lock seat produces reverse currents to stop rotation.

A face spline coupling for transmitting torque between a wheel end unit and a driven shaft arranged in a longitudinal axis of a drive-wheel arrangement for a motor vehicle includes a first face spline formed in the wheel end unit and a second face spline formed in the driven shaft. The first face spline is generally perpendicular to the longitudinal axis and faces the driven shaft, and the second face spline is also generally perpendicular to the longitudinal axis and faces the wheel end unit. The first and second face splines are meshed together and detachably coupled by inter-fitting teeth of each of the first and second face splines. In addition, the teeth in each of the first and second face splines are formed in a helical configuration.

Radially outer ring of a bearing unit for a hub-wheel assembly for motor vehicles, the radially outer ring being provided with: a flange portion having a plurality of axial fixing holes that connect an element of the motor vehicle wheel to the radially outer ring, an almost cylindrical portion which with part of its radially internal surfaces defines raceways for rows of rolling bodies of the bearing unit, an axially internal or axially external surface of the flange portion and a radially external surface of the cylindrical portion connected to each other by a first portion of toroidal surface (St1) and of a second portion of toroidal surface (St2) defined by corresponding first radius (R1) and second radius (R2), a truncated cone surface (Stc) defined by an angle (a) formed with a rotation axis (X) of the radially outer ring is interposed between the first portion of toroidal surface (St1) and the second portion of toroidal surface (St2).

A brake apparatus for a vehicle may include: a caliper body module provided with a finger part and a cylinder part spaced apart from each other and facing each other, a pad plate part disposed between the finger part and the cylinder part, and configured to selectively come into contact with a disk module rotated together with a rotor to generate a braking force, a piston module installed in the cylinder part to be movable forward and backward and configured to press the pad plate part, a guide member disposed on both sides of the caliper body module and configured to movably support the caliper body module, and a first fastening member extending from the guide member and fastened to a first mounting member provided in a stator.

A two-stage speed-change output device includes a main axle, on which a motor assembly and first and second speed-change assemblies are mounted. The first and second speed-change assemblies are mounted inside an output shell by first and second one-way clutching elements, both operating in a forward direction. The motor assembly is operable to rotate backward to drive the first one-way clutching element to drive the output shell to rotate in the forward direction, while the second one-way clutching element idles. The motor assembly is also operable to rotate forward to drive the second one-way clutching element to drive the output shell to rotate in the forward direction, while the first one-way clutching element idles. The device realizes speed change for two stages to drive the output shell in the same direction with forward and backward rotations of the motor assembly.

Sensorised wheel hub unit and a method for detecting, in real time, forces and moments applied to an outer ring of the wheel hub unit in which piezoresistive ceramic plates are made of one piece with welded metal plates housed within respective recesses formed in an outer surface of the outer ring over respective races for rolling elements that there is a gap between the plates and a base wall of each recess; the temperature of the outer ring and the amplitude and frequency of first electrical signals (S1) associated with the sensors relating to the same race are analysed to determine a frequency value equal to the frequency of the first signal having the maximum amplitude and as many amplitude values (D1-Dn) as there are sensors associated with that race and each equal to the maximum amplitude of the first signal from each sensor, corrected according to temperature.

A rear wheel (1) for a powered two-wheeler has a hub (3), a rim (4) which has a rim well (5) and two rim flanges (6) terminating the rim (4) on both sides, at least one connecting element (7) for connecting the hub (3) to the rim (4), an interface (8) for attaching the rear wheel (1) to the two-wheeler, and receptacles (9, 10) provided on both sides of the rear wheel (1) for receiving a brake disc (11) and/or a drive element (12) serving to rotate the rear wheel (1). The receptacles (9, 10) on both sides are identical to one another.

Provided is a wheel bearing apparatus with a generator that can have a simplified structure to reduce costs and is capable of preventing electrolytic corrosion. The wheel bearing apparatus with a generator includes a wheel bearing and a generator. The generator includes a stator attached to a fixed wheel and a motor rotor attached to a rotating wheel and is of an outer-rotor type in which the stator is located on an outer periphery of the wheel bearing, and the motor rotor is located radially outside of the stator. The wheel bearing apparatus with the generator further includes at least one conducting unit that conducts a current between the fixed wheel and the rotating wheel.

A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.
