An automatic transmission may include a rotating shaft; a slider portion provided on the rotating shaft; a first connecting member having one end hinged to the rotating shaft and the other end rising or falling by a centrifugal force as the rotating shaft rotates; a second connecting member having one end hinged to the first connecting member and the other end connected to a slider portion to vertically slide the slider as the first connecting member rises or falls; a diaphragm spring coupled to the slider portion and deformed in an axial direction of the rotating shaft depending on position of the slider portion; a shift fork connected to the slider portion or the diaphragm spring and engaging a synchronizer with a shift stage gear depending on position of the slider portion; an elastic regulator controlling an elastic force of the diaphragm spring; and a controller controlling the elastic regulator.

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 turbomachine train with two shaft parts which each have a fixedly attached grooved wheel, with a first overrunning clutch, with two rotational speed sensors and with a control device. The clutch is designed to couple and decouple the first shaft part to and from the second shaft part. The first rotational speed sensor measures the rotational speed of the first grooved wheel. The second rotational speed sensor measures the rotational speed of the second grooved wheel. The control device determines the differential angle between the first shaft part and the second shaft part and accelerates the turbomachines, with an acceleration value determined on the basis of the measured rotational speeds and on the basis of the differential angle, such that the two shaft parts couple together at a predetermined target coupling angle.

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.

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 synchronizing clutch includes a synchronizing mechanism that can be displaced longitudinally in an axial direction along the longitudinal axis of the synchronizing clutch between a first and a second hub. The mechanism has a synchromesh sleeve with a first ratchet carrier and the synchromesh sleeve has a ratchet located on said carrier. In addition, the ratchet carrier is connected to the first hub in a longitudinally displaceable manner by means of helical toothing. At least one compression spring element is operatively arranged between the ratchet carrier and the first hub and runs parallel to the longitudinal axis of the synchronizing clutch.
