A gas turbine engine assembly includes, among other things, a clutch configured to move from a first position to a second position in response to rotation of a gas turbine engine fan at a speed greater than a threshold speed. Whether the clutch is in the first position or the second position, the clutch permits rotation of the gas turbine engine fan in a first direction. When the clutch is in the first position, the clutch limits rotation of the gas turbine engine fan only in an opposite, second direction. The clutch is disposed within a compartment that is accessible and removable via removal of an aft engine cover structure. The clutch is removable on-wing.

A primary clutch of a continuously variable transmission with a launch mechanism is provided. The primary clutch includes a central post, a fixed sheave assembly, a movable sheave assembly and a locking mechanism. The central post is configured to receive rotational torque from a motor. The fixed sheave assembly is statically mounted on the central post. The movable sheave assembly is mounted on the central post. The movable sheave assembly includes a movable sheave system that is configured to move axially on the central post towards the fixed sheave assembly as RPM of the primary clutch increase. The locking mechanism is configured and arranged to selectively prevent movement of the movable sheave system independent of the RPM of the primary clutch.

An apparatus for automatic shifting of a vehicle may include a rotation shaft connected to an output shaft to rotate together; first connecting members each having a first end portion to which a first link disposed on the rotation shaft is hinged and a second end portion to which a centrifugal weight is disposed, to pivot about the first end portions by centrifugal force; second connecting members each having a first end portion hinged to the middle portion of the first connecting member and a second end portion hinged to a second link disposed on the rotation shaft; a slider disposed on the rotation shaft to be coupled to any one of the first link and the second link and sliding in an axial direction of the rotation shaft; and a shift fork connected to the slider to engage a synchronizer with a shift stage gear.

A drive device for a motor vehicle, with a first drive assembly, a second drive assembly, and an auxiliary drive having at least one auxiliary assembly. The auxiliary drive being coupled to or can be coupled to, respectively, the first drive assembly and the second drive assembly via an epicyclic gear transmission. The auxiliary drive is coupled to a first transmission element of the epicyclic gear transmission. In this case, a second transmission element of the epicyclic gear transmission is coupled by a gearshift transmission, which is shifted in a speed-dependent manner, to an auxiliary-drive drive shaft, which is coupled to or can be coupled to the first drive assembly.

An automatic and intelligent clutch-type wind turbine system clutch-type wind turbine system is revealed. A rotor-blade base is disposed with rotor blades and connected to a main shaft. A gearbox of a split gearbox is connected to the main shaft while a turbine-driven set of the split gearbox is connected to a power shaft. A plurality of sets of disc generators is connected to the power shaft and a synchronous clutch is arranged between the two adjacent disc generators. A battery is connected to each disc generator. Thereby electricity is generated by the wind turbine system without being affected by wind force from surrounding area and the electricity is not wasted on braking. During the electricity generation process, the energy stored is converted into kinetic energy for assistance in generating electricity. Thus not only the power generation efficiency is improved, the total production cost is also reduced.

Provided is an easy engine starting system including: an engine; a centrifugal clutch configured to transmit a driving force of the engine to a driven device; and a control device configured to adjust output of the engine. When the engine is to be started, the engine is accelerated at start engine output which enables the engine to reach a rotation speed higher than a clutch-in rotation speed. The control device has suppression control of suppressing, at the start engine output, the rotation speed to a rotation speed equal to or lower than the clutch-in rotation speed.
