Assignee: DENSO CORPORATION
Field: Mechanical elements (Mechanical engineering)
Classification: CPC F  H | IPC F

Claim 8:
9. A clutch device comprising:
a first transmitter;
a drive device that includes two winding sets and is configured to output torque through energization of the two winding sets;
the rolling element cam of claim 8;
a second transmitter that is configured to transmit the torque between the first transmitter and the second transmitter;
a clutch that is configured to shift an operational state of the clutch to a coupled state or a decoupled state depending on a relative position of the driven cam relative to the drive cam in the axial direction, wherein the clutch is configured to enable transmission of the torque between the first transmitter and the second transmitter through the clutch in the coupled state and disable the transmission of the torque between the first transmitter and the second transmitter through the clutch in the decoupled state; and
a controller that is configured to control the energization of the two winding sets to control an operation of the drive device, wherein:
the controller is configured to control the operation of the drive device such that each of the plurality of rolling elements is rolled along the drive cam slope groove, the drive cam connection groove, the drive cam planar groove of the corresponding one of the plurality of drive cam grooves and the driven cam slope groove, the driven cam connection groove and the driven cam planar groove of the corresponding one of the plurality of driven cam grooves at a normal time, during which none of the two winding sets is broken; and
the controller is configured to control the operation of the drive device such that each of the plurality of rolling elements is rolled along the emergency-time drive cam groove of the corresponding one of the plurality of drive cam grooves and the emergency-time driven cam groove of the corresponding one of the plurality of driven cam grooves at an emergency time, during which one of the two winding sets is broken.
