A driving force transmission mechanism is a mechanism for transmitting rotational force of the second rotor having a driving-side coupling to a first rotor having a driven-side coupling. The driving-side coupling includes a body and a plurality of second engaging members engaging with first engaging members of the driven-side coupling, each of the plurality of second engaging members has at an abutting point on an abutting surface of a corresponding first engaging member a first inclined surface inclined so as to be away from a rotation axis of the body from a downstream side toward an upstream side in a rotation direction of the body.

A power assembly and a vehicle in the field of driving technologies are provided. The power assembly includes a housing, a first rotating shaft, a second rotating shaft, and a preloaded part. The first rotating shaft is located in the housing by using two bearings, the second rotating shaft is located in the housing by using one bearing, and the second rotating shaft can slide in an axial direction. A first coupling portion is disposed on the first rotating shaft, a second coupling portion is disposed on the second rotating shaft, and the first coupling portion is coupled to the second coupling portion, so that the first rotating shaft and the second rotating shaft rotate synchronously.

A steering column has a housing. A steering spindle jacket is disposed within the housing. An outer steering spindle is disposed within the steering spindle jacket and has a spline hub. An inner spindle is disposed within the outer steering spindle and includes a spline shaft configured to permit axial movement and prevent rotation of the outer steering spindle when the spline hub and the spline shaft are engaged. In a non-stowed state the spline shaft and the spline hub are engaged and in a stowed state the spline shaft and the spline hub are free of engagement. A pin is disposed in the housing engages the spline hub portion in the stowed state and prevents rotation of the outer steering spindle and is free of engagement in the non-stowed state.

Example torque tube assemblies for use with aircraft high lift devices are described herein. An example apparatus includes a spline coupling having a first yoke, a sliding splined shaft having a second yoke and a torque tube having a first end and a second end opposite the first end. A first fitting with a third yoke is coupled to the first end of the torque tube, and a second fitting with a fourth yoke is coupled to the second end of the torque tube.

The invention provides a connection device for a joint shaft in a motor vehicle. The connection device includes an axis of rotation, a first connection area for connecting the connection device to a drive train element, a predetermined breaking region, and a tube region which connects directly to the predetermined breaking region. The connection device has an axial extension in the direction of the axis of rotation, and a radial extension orthogonal to the axis of rotation and is designed, at least substantially, as a tubular hollow body. The predetermined breaking region is arranged between the first connection region and the tube region in the axial direction. A connection area is arranged in the axial direction between the first connection region and the predetermined breaking region.

A locking mechanism for a driveshaft disconnect coupling includes an input jaw member defining a rotation axis, an output jaw member connectable to the input jaw member for common rotation with the input jaw member, and a cartridge assembly. The cartridge assembly is fixed to the input jaw member, includes a pin, and defines a pin movement axis. The pin is movable along the pin axis between a radially inner position and a radially outer position, the pin being disengaged from the output jaw member in the radially inner position and the pin being engaged to the output jaw member in the radially outer position.

The invention relates to a drive unit (10) for a vehicle, comprising an electric machine (12) having a rotor shaft (14) and a transmission (16) having a transmission shaft (18). According to the invention, the rotor shaft (14) and the transmission shaft (18) are interlocking and coupled by means of an interlocking toothing (44), wherein a lubricant channel (46) is formed in the transmission shaft (18), which feeds into an inner space (48) of the rotor shaft (14) at the end facing the rotor shaft (14) in order to provide lubricant for the interlocking toothing (44), wherein the rotor shaft (14) has an end side (50) at the axial end facing the transmission shaft (18), on which end side one or more openings (52) are formed, extending from an inner circumference (54) of the rotor shaft (14) bordering the inner space (48) to the outer circumference (56) thereof, such that the lubricant channel (46) is fluidically connected to the openings (52) via the inner space (48) and the interlocking toothing (44).

A mechanical coupling for use with a theatrical hoist including a shaft having a body portion and a head portion defining an external hexagonal end with flanked surfaces in a plane parallel to and radial with a centerline of the mechanical coupling, and a liner including an internal hexagonal end corresponding to the external hexagonal end of the shaft. The flanked surfaces of the external hexagonal end are configured to engage with the internal hexagonal end of the liner. The mechanical coupling enables transmission of a moment about an x-axis of the mechanical coupling and enables transmission of forces along a y-axis and a z-axis of the mechanical coupling. The mechanical coupling inhibits transmission of moments about the y-axis and the z-axis of the mechanical coupling and inhibits transmission of forces along the x-axis.
