An integrated disconnect arranged within a housing, comprising:
- an output gear having a cavity;
- a torque transfer adapter, arranged within the cavity, that is configured to receive a half shaft;
- a clutch body arranged within the cavity, wherein the clutch body is actuatable through the output gear by a solenoid coupled to the clutch body and located external to the cavity, wherein the solenoid is configured to translate the clutch body to an engaged position relative to the torque transfer adaptor;
- and
- a return mechanism affixed to the clutch body, wherein the return mechanism is configured to translate the clutch body into a disengaged position such that the clutch body is separated from the torque transfer adapter.
A vehicle powertrain, comprising:
- a motor;
- and
- an integrated disconnect arranged within a housing, wherein the integrated disconnect interfaces with the motor through a drive unit, the integrated disconnect comprising:
- an output gear having a cavity;
- a torque transfer adapter, arranged within the cavity, that is configured to receive a half shaft;
- a clutch body arranged within the cavity, wherein the clutch body is actuatable through the output gear by a solenoid coupled to the clutch body and located external to the cavity, wherein the solenoid is configured to translate the clutch body to an engaged position relative to the torque transfer adaptor;
- and
- a return mechanism affixed to the clutch body, wherein the return mechanism is configured to translate the clutch body into a disengaged position such that the clutch body is separated from the torque transfer adapter.
A dual integrated disconnect, comprising:
- a first output gear having a first cavity;
- a first torque transfer adapter, arranged within the first cavity, that is configured to receive a first half shaft;
- a second output gear having a second cavity that opposes the first cavity;
- a second torque transfer adapter arranged within the second cavity;
- a clutch assembly arranged within the first cavity and the second cavity, wherein the clutch assembly is actuatable to an engaged position relative to one or more of the first torque transfer adaptor or the second torque transfer adapter, and
- a return mechanism configured to translate modify the clutch assembly into a disengaged position such that the clutch assembly is separated from the first torque transfer adapter and the second torque transfer adapter.
