A universal joint contains a first joint yoke and a second joint yoke. The first joint yoke and the second joint yoke are connected by a journal cross, ends of the journal cross being mounted in the joint yokes by bearings. In order to lubricate at least one of the bearings, at least one lubricant feed-through is provided, which is provided outside of a central bore of the journal cross.

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 protection system (5) comprises a first tubular member (13) and a second tubular member (15) which can be slidably inserted into each other and a protection (8) at one end of the first tubular member (13). The protection comprises a protective boot (40) and a first annular element (21) fixed to the first tubular member (13). Further provided for is a second annular element (33) which can be torsionally coupled to the first annular element (21) and which can be decoupled therefrom by means of a mutual movement between the first annular element (21) and the second annular element (33) in a direction approximately parallel to the axis (A-A) of the first tubular member (13). The second annular element (33) is coupled to the protective boot (40) which is provided with members (49) for coupling to a stationary plate (51) which can be connected to a power take-off (9). A drive shaft provided with such a protection system is also described.

Disclosed is a driveshaft joint embodiment providing increase of driveshaft joint strength and longer life by keeping the rotational diameter fixed and providing placement under the vehicle in dimensional terms subject to the rotation diameter thanks to the embodiment provided on the driveshaft joint.

Articulable joints having diamond bearing surfaces engaged with metal bearing surfaces are provided herein. The articulable joints provide multiple degrees of freedom to components, such as drivelines, and bear loads in multiple directions. The articulable joints include diamond bearing surfaces slidingly engaged with opposing metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst.

A universal joint assembly includes a yoke including a serration hole to receive an end portion of a steering column and a bolt-hole to receive a bolt which is used to restrict the steering column received in the serration hole, and a misassembly prevention member coupled to the yoke and elastically movable from a first position in which the bolt-hole is at least partially blocked to a second position in which the bolt-hole is opened, thereby preventing a misassembly of the steering column and improving safety and reliability of the universal joint assembly.

A steering shaft for a motor vehicle may have an inner shaft, an outer shaft, and a profiled sleeve that is fixed on the inner shaft such that the inner shaft is movable together with the profiled sleeve in an axial direction relative to the outer shaft. The inner shaft and the outer shaft may be coupled in a torque-transmitting manner with the profiled sleeve connected therebetween. The profiled sleeve may comprise an aperture into which a projection on an outer face of the inner shaft engages in a manner that secures the profiled sleeve in position on the inner shaft at least in the axial direction.

A coupler configured to provide an articulated connection about two axes of rotation between a first member and a second member. The coupler can include a first end that defines a first bore therethrough and a second bore at least partially therethrough and a second end that defines a third bore therethrough. The first bore and the second bore can partially intersect one another.
