A wheel bearing unit for a motor vehicle, comprising a wheel hub, a wheel bearing housing and a rolling bearing by which the wheel hub is mounted rotatably in relation to the wheel bearing housing. The rolling bearing has at least one row of rolling elements which are guided on the wheel hub side in a bearing inner ring which is designed as a separate component in relation to the wheel hub and which is fixedly connected to the wheel hub. The wheel hub has a through opening with an inner toothing, via which through opening the wheel hub can be connected in a non-rotational manner to a drive journal which is provided with an external toothing.

A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub body includes a first spoke-mounting portion, a second spoke-mounting portion, and a first axial length. The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction and is equal to or larger than 55 mm. The sprocket support body includes a plurality of external spline teeth. The plurality of external spline teeth includes a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radial length defined from a radially outermost edge to a radially innermost edge. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm.

A reinforcement for a hub ratchet base comprising a chain-ring and a ratchet ring. The chain-ring is made of an aluminum material having a chain-ring socket and an assembly shaft. The ratchet ring is made of a metal material with high hardness which can be the titanium alloy material or the chrome-molybdenum steel material. The ratchet ring has an engaging slot corresponding to the assembly shaft of the chain-ring. There are at least three connecting slots disposed on the ratchet ring for accepting at least three ratchet members and at least three corresponding elastic members. Each of the connecting slots of the ratchet ring has a pivoting portion on an end for engaging with a ratchet member and an engaging portion on another end for engaging with an elastic member such that the elastic member pushes against a bottom portion of the ratchet member.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

A method for manufacturing a hub unit includes: preparing a hub unit intermediate including an inner shaft, an inner ring fixed to an axial end of the inner shaft, and an outer ring rotatably arranged with respect to the inner shaft and the inner ring; preparing a magnetic seal member including a seal member and an annular magnetic member having no magnetic pole; and arranging the magnetic seal member between the inner ring and the outer ring of the hub unit intermediate. The method further includes: forming splines extending along the axial direction by cutting the inner circumferential surface of the inner shaft of the hub unit intermediate in which the magnetic seal member has been arranged; and forming magnetic poles in a circumferential direction of the magnetic member of the hub unit intermediate in which the plurality of splines have been formed.

A vehicle wheel arrangement includes a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for arrangement of a power-transmitting unit. In a joined state of the vehicle wheel arrangement a joining portion of the wheel hub corresponds with a joining portion of the carrier element. In the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of a wheel hub axis. The wheel hub includes, in a region of the joining portion, one or more fiber plies with fibers arranged unidirectionally in the circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub made of fiber-reinforced composite and a carrier element.

An in-wheel motor drive device (10) includes: a wheel hub bearing portion (11); a motor portion (21) and a deceleration portion (31) disposed in an upwardly offset manner with respect to an axis of the wheel hub bearing portion (11); and a carrier (101) projecting downward to a position below the wheel hub bearing portion (11). A suspension connection portion (101c) is mounted on a lower end of the carrier (101), the suspension connection portion (101c) to be connected with a suspension device (116) so as to be directable in any direction. The suspension connection portion (101c) is disposed in an overlapping manner with the wheel hub bearing portion (11) with respect to a position in an axial direction of the wheel hub bearing portion (11).

A bicycle hub assembly comprises a hub axle, a hub shell, and a sprocket support body. The sprocket support body includes a tubular part, a first sprocket engaging tooth, and a second sprocket engaging tooth. The tubular part includes an outer peripheral surface and an attachment portion. The first sprocket engaging tooth includes a first radially outer surface provided radially outward of the outer peripheral surface. The second sprocket engaging tooth includes a second radially outer surface and a third radially outer surface. The third radially outer surface is provided radially outward of the outer peripheral surface and radially inward of the second radially outer surface. A first distance is defined from the outer peripheral surface to the first radially outer surface. A second distance is defined from the outer peripheral surface to the third radially outer surface. The second distance is shorter than the first distance.

A vehicle wheel supporting rolling bearing unit includes a stationary side bearing ring member, a rotation side bearing ring member, and plural rolling elements. The rotation side bearing ring member is provided with a first acceleration sensor, a second acceleration sensor, and a third acceleration sensor which are fixed on a virtual plane orthogonal to a center axis of the rotation side bearing ring member. The first acceleration sensor and the second acceleration sensor are arranged on a virtual line passing through a rotation center of the rotation side bearing ring member with a same distance from the rotation center while detection directions thereof are directed in a radial direction and are opposite to each other in the radial direction. The third acceleration sensor is arranged such that a detection direction thereof is non-parallel to the detection directions of the first acceleration sensor and the second acceleration sensor.
