A wheel support bearing assembly includes a wheel support bearing and a power unit. The power unit is that of an outer rotor design in which a stator is located at an outer periphery of the wheel support bearing and a rotor is located radially outward of the stator. A radial extension of the entire power unit is sized to be radially inward of a peripheral section of a brake rotor. An entirety of the power unit, excluding a mount part thereof to a hub flange, is sized to be situated in an axial range between the hub flange and a mount surface, on an inboard side of the wheel support bearing. The rotor includes an outer shell magnetic body, which is made from soft magnetic material and forms an outer shell of the power unit, and permanent magnets that are provided to the outer shell magnetic body.

Example torque tube assemblies for use with aircraft high lift devices are described herein. An example apparatus includes a spline coupling having a first yoke, a sliding splined shaft having a second yoke and a torque tube having a first end and a second end opposite the first end. A first fitting with a third yoke is coupled to the first end of the torque tube, and a second fitting with a fourth yoke is coupled to the second end of the torque tube. The third yoke is coupled to the first yoke to form a first U-joint, and the fourth yoke is coupled to the second yoke to form a second U-joint. The spline coupling is to be coupled to a first high lift device drive shaft and the sliding splined shaft is to be coupled to a second high lift device drive shaft.

The invention provides a connection device for a joint shaft in a motor vehicle. The connection device includes an axis of rotation, a first connection area for connecting the connection device to a drive train element, a predetermined breaking region, and a tube region which connects directly to the predetermined breaking region. The connection device has an axial extension in the direction of the axis of rotation, and a radial extension orthogonal to the axis of rotation and is designed, at least substantially, as a tubular hollow body. The predetermined breaking region is arranged between the first connection region and the tube region in the axial direction. A connection area is arranged in the axial direction between the first connection region and the predetermined breaking region.

A power transmission shaft comprises a shaft unit interposed between first and second shafts; an engaged portion provided on one end of the second shaft and having an annular stepped part provided between a smaller diameter portion and a larger diameter portion; and an engaging portion provided on one end of the shaft unit and joinable with the engaged portion to rotate together about a common rotation axis, wherein the engaging portion comprises a cylindrical base portion that rotates together with the shaft unit, an elastically shrinkable cylindrical portion that is provided on one axial end of the cylindrical base portion to project toward the engaged portion and catching pawls that are provided by the elastically shrinkable cylindrical portion and latchingly engageable with the annular stepped part when the engaged portion and the engaging portion are coaxially arranged and joined with each other.

A shaft connection 1 for a longitudinal shaft assembly, has at least a first shaft having a first and second ends, and a second shaft, disposed so as to be coaxial with the first shaft, having first and second ends; the shafts extending axially. The first end forms a hollow portion. The first shaft end forms a first journal having a displacement portion. The first shaft end at least in an initial position of the shaft connection extends through the hollow portion which axially by the displacement portion forms a guide portion and circumferentially forms a form-fitting first connection. In the initial position a mutual axial displacement of the first and second shafts is prevented by an axial securing feature. In a crash the axial securing feature; is releasable by an axial release force. The first shaft is axially displaceable relative to the second shaft.

A transmission shaft is provided comprising an input side for inputting torque, an output side for outputting torque, and a rod extending in a longitudinal direction between the input side and the output side to transfer torque along the transmission shaft. The rod comprises a first end provided at the input side, a second end provided at the output side and a torsional compliant section extending therebetween providing the transmission shaft with a torsional stiffness. The torsional compliant section comprises a cross-section which extends in the longitudinal direction to define a central core for transmitting torque directly from the first end to the second end and a radially outer section. This section also comprises a plurality ribs which extend radially and longitudinally from an outer periphery of the central core for increasing transverse stiffness of the rod.

A motor vehicle drive shaft has a receptacle tube component with a receptacle internal diameter and a push-fit component with a push-fit external diameter. The push-fit external diameter is smaller than or equal to the receptacle internal diameter. The receptacle tube component and the push-fit component can be rotated about a common drive shaft rotational axis and extend along the latter in a longitudinal direction. The receptacle tube component and the push-fit component are connected to one another for the transmission of torque. A connecting component is provided, wherein the connecting component is connected in a torque-conducting manner to the receptacle tube component by way of a receptacle connection. The connecting component is connected to the push-fit component by way of a push-fit connection. At least one of the two connections is configured as a combined frictionally locking and positively locking shaft/hub connection.

A drive shaft has a central tubular portion formed of a polymer composite with imbedded fibers. It extends between a first end and a second end. The central tubular portion has an outer peripheral surface. There is at least one ring on the outer peripheral surface of the central tubular portion. A method of repairing a composite material tube includes the steps of (a) identifying a damaged area on a composite tube, and (b) placing a patch on a surface of the tube and over the damaged area.

An aircraft drive shaft including an outer shaft having a first diameter configured to couple a first gearbox and a second gearbox to provide power transfer between the two gearboxes, an inner shaft concentric with the outer shaft and having a second diameter configured to provide structural support to the outer shaft, a gap defined between an outer peripheral surface of the inner shaft and an inner peripheral surface of the outer shaft, wherein the gap is sized according to a ballistic projectile cross-section size that the aircraft is considered to encounter on an upcoming mission, and a sleeve located at least at first end of the outer shaft connecting the outer shaft to the inner shaft.

A bracket assembly for use in a vehicle. The bracket assembly includes one or more first center bearing brackets, one or more plates, and one or more attachment members. At least a portion of the one or more plates are connected to at least a portion of the first center bearing bracket and to at least a portion of a body or frame of a vehicle. Additionally, at least a portion of the one or more attachment members are connected to at least a portion of the first center bearing bracket, to at least a portion of the one or more plates, and/or to at least a portion of the body or frame of the vehicle.
