| 20110284338 | Arrestor - A system having a rotary output, including a drive shaft, a pin coupled to the drive shaft and an output shaft coupled to the drive shaft. A guideway is associated with the output shaft. Rotation of the drive shaft results in rotation of the output shaft and the guideway and movement of the pin along a pin path.

| 20140166425 | HYDRAULIC ACTUATING PIN SYSTEM - A hydraulic actuating pin system is disclosed with an actuating pin, clutch drum, spring and hydraulics. The clutch drum has a scalloped annulus with raised and lowered sections. The spring pushes the pin towards the scalloped annulus. When the pin extends into the lowered section, it prevents the clutch drum from rotating. The hydraulics can compress the spring and extract the pin to allow the clutch drum to rotate. The proximal end of the pin can include a head, and hydraulic pressure can move the head to compress the spring. When the pin is fully extended into the lowered section, the end of the pin can not touch the bottom of the lowered section. The hydraulics can include a one-way valve allowing flow from a pump source to the pin, and a pressure release orifice allowing controlled release of hydraulic pressure from the pin. | 06-19-2014 |

Also provided is a spring, which acts at least indirectly on the shift element and preloads the latter in the direction of the engaged or disengaged position, whereas an electromagnet serves to move the shift element counter to the preloading effect of the spring in the energized state. | 10-29-2015 |

| 20140299438 | QUICK DISCONNECT FOR A DRIVE UNIT - A drive unit disconnect mechanism is operable to transmit or disconnect power from a vehicle power source to a driven unit, and can be disengaged by multiple methods depending on how much force is required to separate the internal components of the mechanism. In a first, relatively quicker method, a handle is pulled axially away from the hub to withdraw and internal gear from splined engagement with a corresponding driven gear. In a second, relatively slower method, the handle is rotated to threadably withdraw the entire disconnect mechanism from the hub, which in turn withdraws the internal gear from splined engagement with the driven gear. The quicker method is desirable in most instances, but the slower method allows disconnection of the driven unit from the vehicle power source when gear pressure prevents or impedes the quicker method. | 10-09-2014 |
