A disconnect mechanism comprises an input shaft defining a drive axis, a disconnect shaft selectively engaged with the input shaft to be driven about the drive axis by the input shaft, and a disconnect ramp operatively connected to the disconnect shaft to axially move the disconnect shaft between at least a first axial position and a second axial position. A disconnect pawl is selectively engaged with the disconnect ramp shaft, and a brake is selectively engaged with the disconnect shaft in the second axial position.

A gear shifting device is provided, by which an axial shift movement of a shift element into a shift position through interaction of a shift pin with an associated groove-like shift gate that is changeable in an axial direction. The shift element features, on an inner diameter and/or an outer diameter, the associated shift gate, while the respective shift pin is arranged in a radially opposite and displaceable manner on a transmission component adjacent to the shift element. As an alternative, the shift element, on an inner diameter and/or an outer diameter, accommodates the respective shift pin in a radially displaceable manner, whereas the associated shift gate for the respective shift gate is arranged to be radially opposite on a transmission component located adjacent to the shift element. The shift pin is movable through an associated actuator in a radial manner between an initial position and a mesh position in which each shift pin is introduced into the associated shift gate.

Methods and systems are provided for operating an electromagnetic coil assembly. As one example, a method comprises responsive to energization of an electromagnetic coil of an electromagnetic coil assembly, translating the electromagnetic coil along a central axis of the electromagnetic coil assembly toward a magnetic armature while maintaining the armature fixed along the central axis. The electromagnetic coil assembly may be utilized within various clutching, braking, or lever applications.

An engagement device includes: an engaged body configured to rotate in conjunction with a rotary shaft; an engaging body arranged coaxially with the engaged body and configured to engage with the engaged body by movement in an axial direction; a power source configured to provide thrust to the engaging body in the axial direction; and a hub member configured to couple the engaging body to a torque receiver which receives torque transmitted from the engaged body at a time the engaging body engages with the engaged body. The engaged body, the engaging body, and the power source are accommodated in a closed space, and the hub member is at least a part of an outer shell forming the closed space.

A fluid pump (10) for a motor vehicle comprising a pump rotor (20) for pumping a fluid, a shaft (12) for driving the pump rotor (20) and a clutch (16) for the switchable coupling of the shaft (12) to the pump rotor (20). The clutch (16) is designed to connect the shaft (12) to the pump rotor (20) in a positive-locking manner and to separate said shaft from said pump rotor.

The present invention relates to a two-speed transmission for an electric driving vehicle and the two-speed transmission for an electric vehicle has only one actuator. The transmission comprises a planetary gear mechanism (12), an elastic body (44), an armature (26) to integrally rotate with an input axis, an electromagnetic coil (46) and a multi-plate friction clutch (30). A ring gear (20) is fixed to a housing. The armature (26) comprises clutch projection portions (26-1). A dog clutch is constituted by the clutch projection portions (26-1) and recess portions (18-2) of a sun gear (18). When the electromagnetic coil (46) is not electrically energized, the dog clutch is engaged. The rotation of the input axis is reduced and is transmitted to an output axis via the sun gear (18) and a carrier (16). When the electromagnetic coil (46) is electrically energized, the armature (26) is displaced against elastic force, the dog clutch becomes a non-engaging state, a multi-plate friction clutch (30) becomes an engaging state by pressing flange portions (26-4) of the armature (26) and the rotation of the input axis is transmitted to the output axis with a one-to-one relationship. The transmission can comprise a one-way clutch to prevent torque interruption when switching the gear ratio.

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 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.
