A device for compensating for axial play, notably for a motor vehicle, having a first element that is intended to be fixed axially with respect to a crankshaft, a second element that is intended to be fixed axially with respect to a gearbox, play compensation means having tabs that are elastically deformable in the axial direction, said tabs extending circumferentially between the first and second elements so as to transmit a torque from one element to the other.

An industrial work vehicle including a frame and a first shaft rotatably connected to the frame via first and second bearings. The work vehicle further includes a second shaft rotatably positioned in line with the first shaft and connected to the first shaft via a coupling. The second shaft is further connected to the frame via a third bearing. The coupling includes a first connection and a second connection. The first connection connects the first shaft to the second shaft via a fourth bearing adapted to support a radial load and to accommodate an axial rotation and an angular misalignment of one shaft with respect to the other shaft. The second connection connects the first shaft to the second shaft via flange elements which are interconnected via an intermediary element adapted to transmit a torque and to accommodate a misalignment of one shaft with respect to the other shaft.

A selective torque transfer device is provided to transfer torque between one rotating component and a decoupled non-rotating component. The torque transfer device has an input shaft that extends along an axis and is connected to an input hub. The input shaft and input hub rotate about the axis on which they extend. A slider is disposed within the input hub and is capable of moving in a direction transverse to the axis. An output shaft extends along the axis and is connected to an output hub. The output shaft and output hub rotate about the axis on which they extend when the selective torque transfer device is in the engaged position. A link pivotally connects the output hub to the slider. The input hub is configured to rotate about its axis to create a torque.

A light weight hybrid torque transfer joint trunnion has an integral metal hub spline fitting oriented on a center axis. This integral metal hub spline fitting may be made of steel, aluminum, titanium, or the like and may be generally cylindrical. The integral metal hub spline fitting defines an integral central internally-splined mast or driveshaft coupling opening centered about the center axis. A composite material body centrally retains, and is cured to, the metal hub spline fitting. Torque transfer joint link attachment pins extend from the composite material body and are rigidly linked to the metal hub spline fitting. In an example constant-velocity joint, a plurality of pivoting linkages may each be rotatably coupled to the torque transfer joint link attachment pins, and each of the plurality of pivoting linkages may, in turn be secured to a rotor yoke configured to mount a plurality of rotorcraft blades.
