An engine transmission is provided with an interference member that is configured to interfere with one of a low-gear clutch sleeve and a high-gear clutch sleeve so that when one of the low-gear clutch sleeve and the high-gear clutch sleeve is at an engagement position, the other one of the low-gear clutch sleeve and the high-gear clutch sleeve cannot move to an engagement position.

A disconnect apparatus including a first clutch member and a second clutch member in selective engagement with the first clutch member. The disconnect apparatus also includes a cam mechanism and a sensor assembly. The cam mechanism includes an axially movable first cam member and an axially fixed second cam member. Wherein the sensor assembly generates a pulse pattern which is utilized to determine a position of the first cam member, and thereby a state of the disconnect apparatus.

An axle disconnect apparatus having a cam cylinder including a ramp disposed in a radially outer surface thereof. A first clutch element disposed at least partially inside the cam cylinder and an intermediate shaft disposed at least partially within the first clutch element. The intermediate shaft includes a splined portion in constant mesh with the first clutch element. A half shaft may be disposed coaxially with the intermediate shaft, and a second clutch element may be coupled with the half shaft. The first clutch element selectively engages the second clutch element. The axle disconnect apparatus further comprises a latching mechanism whereby the cam cylinder maintains an axial position. The latching mechanism including a radial depression in the cam cylinder ramp, and a cam follower selectively disposed at least partially in the radial depression.

A generator arrangement includes a housing with a mounting feature, a main generator with an outboard shaft arranged within the housing and axially offset from the mounting feature along a rotation axis, and a permanent magnet generator. The permanent magnet generator has an inboard shaft arranged within the housing between the main generator and the mounting feature. The outboard shaft is coupled to the inboard shaft to provide rotation to the main generator through the permanent magnet generator. Accessory gearboxes and methods of generating electrical power are also described.

A power transmission apparatus for transmitting power generated by a power generation apparatus to a generator and a power generation system including the same are provided. The power transmission apparatus for transmitting power generated by the power generation apparatus to the generator may include a first disk part connected to one of the power generation apparatus and the generator, a second disk part connected to the other one of the power generation apparatus and the generator and disposed on a rear side of the first disk part, and a connection part configured to connect the first disk part and the second disk part and include a portion that decreases and then increases in diameter along a longitudinal direction.

The present disclosure discloses an electric linear actuator, comprising: an electric motor, a transmission assembly in transmission connection with the electric motor, and a sleeve assembly in transmission connection with the transmission assembly, wherein the sleeve assembly comprises a main shaft, and a clutch device for implementing power connection or disconnection between the main shaft and the transmission assembly is provided between the main shaft and the transmission assembly, the clutch device comprising a ball clutch. The present disclosure solves the problem of poor smoothness of the existing electric linear actuators upon power connection or disconnection; besides, the present disclosure has a higher transmission efficiency and a longer service life.
