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.

The present invention provides a disconnector apparatus including: a support ring provided in a differential casing and configured to support a pinion gear mounted therein; a clutch ring having one end penetrating the differential casing, provided in the differential casing, and configured to be coupled to or decoupled from the support ring; an actuator configured to press the other end of the clutch ring to couple the support ring and the clutch ring; and an elastic member coupled to an exposed portion of the clutch ring positioned outside the differential casing, the elastic member having one end in contact with the differential casing and the other end in contact with the actuator.

A two-tracked vehicle is powered by an electric machine which operates as a motor to rotate output shafts via an axle differential with each of the output shafts coupled to a vehicle wheel. One of the output shafts is subdivided into a wheel-side shaft portion and an electric-machine-side shaft portion which can be drivingly coupled to each other by a form-fit coupling to bring the electric machine into driving connection with the vehicle wheels during driving operation. The wheel-side shaft portion and electric-machine-side shaft portion can be decoupled from each other to prevent drag losses during driving operation when the electric machine is deactivated.

The present invention provides a clutch and a work machine having same. The clutch comprises an input member for receiving a driving force and rotating, an output member for outputting rotational motion, and at least one transmission member. The input member has at least one radially extending protrusion. The output member has at least one transmission engagement part. The transmission member is movable between a first position of engagement with the transmission engagement part and a second position of disengagement, being located in a path of rotation of the protrusion, and able to abut the protrusion and be driven to move to the first position. Displacement of the transmission member between the first position and second position has a radial component. According to the technical solution of the present invention, the function of automatically switching between transmission states according to the operating state of a prime mover can be achieved. The fact that displacement of the transmission member comprises a radial component helps to reduce the axial thickness of the clutch, so that the structure thereof is more compact.

A disconnect mechanism to disconnect an electric machine from an ancillary component includes a ramp shaft connected to a disconnect shaft of the electric machine, and connected to the ancillary component, such that when connected to the ancillary component the disconnect shaft transmits rotational energy between the electric motor and the ancillary component. The ramp shaft includes a disconnect feature. A plunger is selectably engageable with the disconnect feature to disconnect the ramp shaft from the disconnect shaft. The disconnect feature includes a drop-in window for initial engagement with the plunger, and a ramp surface extending in a circumferential direction from the drop in window at an acute angle relative to the drop in window. Engagement of the plunger with the ramp surface urges movement of the ramp shaft in an axial direction away from the disconnect shaft to disconnect the ramp shaft from the disconnect shaft.
