| 20080245636 | CLUTCH, MOTOR DEVICE, AND VEHICLE DOOR OPENING AND CLOSING APPARATUS - When a drive shaft is in a non-drive state, a second drive rotor is in a non-engaged state with a driven rotor with respect to its own rotating direction. When the drive shaft is in a drive state, a rotating force of a first drive rotor is transmitted to the second drive rotor through an urging member. As a result, a power transmitting member revolves, and a centrifugal force arranges the power transmitting member at a second clamping position. The second drive rotor receives a reaction force from a driven rotor via the power transmitting member. As a result, the second drive rotor is relatively rotated in an opposite direction to a rotating direction of the first drive rotor with respect to the first drive rotor, against an urging force of the urging member. As a result, the first drive rotor is engaged with the driven rotor with respect to its own rotating direction. Accordingly, the clutch is stably operated. | 10-09-2008 |
| 20100282561 | METHOD FOR KISS POINT ADAPTATION - A method for adjusting the point of engagement of a friction clutch of a step-variable transmission for a motor vehicle, in particular a friction clutch of a dual clutch transmission. The friction clutch is controllably actuated by means of a clutch actuator and at least one synchronizer shifting clutch is controllably actuated by means of a shift actuator for the engagement and disengagement of a gear ratio of the spur-gear transmission. A set-point of the clutch actuator for the point of engagement of the friction clutch is adjusted as a function of a speed gradient value, which ensues from a transitional state with the friction clutch actuated and the shifting clutch actuated, once the shifting clutch is opened. The transitional state is established by setting the clutch actuator and the shift actuator to a respective transitional value substantially at the same time or, at least in sections, in parallel. | 11-11-2010 |
| 20140318918 | TRANSMISSION INCLUDING DOG CLUTCH ARRANGEMENT AND METHOD - A transmission includes a housing, a first shaft rotatably supported relative to the housing, and a second shaft rotatably coupled to the first shaft. A switch-type clutch assembly is movable between an engaged state having a first clutch member coupled to a second clutch member and a disengaged state having the first clutch member separated from the second clutch member. The housing rotates with the first shaft when the switch-type clutch assembly is in the engaged state. A friction clutch is movable between an engaged state having a first friction plate coupled to a second friction plate and a disengaged state having the first frication plate separated from the second frication plate. The second shaft is fixed for rotation with the first shaft via the housing when the switch-type clutch assembly and the friction clutch assembly are both in the engaged state. | 10-30-2014 |

| 20150337911 | CLUTCHED MOTOR AND DEVICE FOR OPENING AND CLOSING OPENABLE BODY - First and second clutches allow first and second tubular output shafts to pivot when a motor generates rotation at a second rotation speed or higher. A third clutch allows a pivot shaft to pivot when the motor rotates at a speed lower than a first rotation speed. A control plate is arranged at a first pivot position, second pivot position, or third pivot position. At the first pivot position, the first and second tubular output shafts are moved to positions in an axial direction allowing first and second rotated members to rotate. At the second pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the first rotated member to rotate. At the third pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the second rotated member to rotate. | 11-26-2015 |

| 20120152685 | TORQUE TRANSMITTING ASSEMBLY WITH DOG CLUTCH AND PLATE CLUTCH FEATURES - A torque transmitting assembly for selectively transmitting torque between a first member and a second member includes a plate clutch interconnected between the first member and the second member, the plate clutch having a maximum torque capacity limited to enabling full throttle single-transition up-shifts in the transmission when the plate clutch is fully engaged. A dog clutch is connected to the first member and selectively connected to the second member.

| 20120234641 | THROUGH-CONNECTION CLUTCH AND METHOD FOR THE ACTUATION THEREOF - A through-connection clutch, for transferring torque between a motor and transmission of a vehicle, which has a friction clutch and a form-locking clutch. The form-locking clutch is disposed radially within the friction clutch, and the clutches can be actuated independently of each other. To minimize the required installation space, the through-connection clutch can be activated flexibly, but is still inexpensive to produce and ensures low-wear yet safe and comfortable torque transfer in a drive train of a vehicle. A pressure plate of the friction clutch and a form-locking element of the form-locking clutch are concentric, rotationally fixed together, and movable toward one another, and can be actuated via an actuation unit, which is rotationally decoupled from the pressure plate and the form-locking element. Depending on the operating situation, the friction clutch and/or the form-locking clutch is selectively activated one or more times. | 09-20-2012 |

| 20140166422 | TRANSMISSION CLUTCH ASSEMBLY - A clutch assembly is disclosed that combines a positively engaging dog clutch and one way clutch. The two devices are design such that the one way clutch never interferes with the engagement or disengagement of the dog clutch. In one embodiment, the one way clutch transmits torque in particular rotational positions and the dog teeth are circumferentially placed such that they do not engage in any of these positions. In another embodiment, the dog clutch piston, to which the teeth are secured, is permitted to rotate enough to accommodate any interference between dog teeth during engagement. In either embodiment, the teeth faces that transmit torque in the same direction as the one way clutch may be angled such that torque in that direction tends to disengage the dog clutch. | 06-19-2014 |
