A method for coupling a rotating device, in particular a steam turbine, and a shaft device, in particular a gas turbine, having the following steps: detecting a differential angle between the shaft device and the rotating device; detecting a differential speed between the shaft device and the rotating device; predicting a coupling angle at which the rotating device and the shaft device would be coupled if the rotating device were accelerated with a known acceleration up to the start of the coupling-in; comparing the predicted coupling angle with a target coupling angle, and calculating therefrom a setpoint acceleration such that the predicted coupling angle matches the target coupling angle.

A hybrid drive vehicle having: at least one driving wheel; an internal combustion engine provided with a drive shaft; an electric machine provided with its own shaft; a gearbox which transmits motion to the driving wheel; a disengagable coupling which acts as a synchroniser and is interposed, to establish a disconnectable mechanical connection, between the drive shaft and the shaft of the electric machine; and a transmission shaft interposed, to establish a permanent mechanical connection, between the shaft of the electric machine on the opposite side to the coupling and the gearbox.

A clutch includes inner and outer races, each with pluralities of teeth. A pawl is supported on the inner race and a shift ring disposed outward of the pawl defines pawl engagement surfaces on an inner perimeter. Pins engage cam surfaces formed in the ring and outer race. When the inner race rotates faster than the outer race, the pawl engages the ring causing relative movement between the ring and outer race that moves the pins radially inward along the cam surfaces to locate the pins between corresponding teeth on the races and rotatably couple the races. When the outer race rotates faster than the inner race, the ring moves relative to the outer race and the pins move radially outward along the cam surfaces away from the corresponding teeth to uncouple the races, disengage the ring from the pawl and allow the outer race to overrun the inner race.

A clutch assembly for a transmission having a gear radially supported relative to a shaft in which the clutch assembly includes a clutch plate rotationally coupled to the shaft. The clutch plate further includes an engaged state whereby a surface of the clutch plate abuts a surface of the gear to rotationally couple the gear to the shaft and a disengaged state whereby the clutch surface is spaced from the gear surface to rotationally uncouple the gear and the clutch plate. A transmission assembly includes a first shaft, a second shaft, and a plurality of gears interconnecting the first shaft and the second shaft such that each gear of the plurality of gears is radially supported by one of the first and second shafts. The transmission assembly can further include a plurality of the clutch assemblies.
