20110009234 | Stabilizing a Planetary Pinion carrier of an Automatic Transmission - An assembly for stabilizing a gear unit of a transmission for an automotive vehicle includes a first component fixed against displacement along an axis, a carrier facing the first component, supported for rotation about the axis, and supporting planet pinion thereon, and springs located between the first component and the carrier, producing axial forces distributed angularly around the axis and applied to the carrier. | 01-13-2011 |
20110082003 | Control of Parallel Reaction Brakes in a Transmission - A method for controlling brakes of an automatic transmission including a first brake arranged in parallel with an overrunning brake between a planet pinion carrier and a housing, includes using the overrunning brake to provide brake torque equal to or less than a reference brake torque under positive torque conditions, increasing a torque capacity of the first brake when brake torque is greater than the reference brake torque, and fully engaging the first brake. | 04-07-2011 |
20110297505 | Transmission Control During Park Range Disengagement - A method for controlling a vehicle transmission during a park release event includes engaging a park brake to hold vehicle wheels against rotation, holding against rotation a first component and a second component of an epicyclic gear unit connected to the wheels, releasing the park brake, selecting a transmission drive range, releasing said first component, and operating the transmission in the selected drive range. | 12-08-2011 |
20140045643 | INTEGRATED PINION CARRIER AND OVERRUNNING ELEMENT RACE - A pinion carrier includes a first disc including ring segments, each ring segment extending angularly about an axis and spaced angularly from the other ring segments, a second disc, spacers secured to the discs and separating the discs axially, and retention elements, each retention element secured to one of the ring segments. | 02-13-2014 |
20140116835 | VEHICLE PARK LOCK ASSEMBLY - A park assembly includes a park gear, a pawl that engages and disengages the park gear, a park rod that causes the pawl to engage with the park gear and to disengage from the park gear, a servo, and a bellcrank transmitting a first force to the park rod causes the pawl to disengage from the park gear in response to a second force substantially greater than the first force and produced by the servo. | 05-01-2014 |
20140216885 | PARK BRAKE ACTUATOR - A park-brake actuator includes a cam including first serrations and an open-ended slot, a piston including second serrations displaceable relative to the cam in response to variable pressure applied to the piston, a spring, and a rod including a pin urged by the spring toward the slot and contact with the first and second serrations, the pin moved by piston displacement from the slot, onto one of the first serrations to a flat-tow position. | 08-07-2014 |
20140238811 | ELECTROMAGNETICALLY ACTUATED AXIAL ONE-WAY CLUTCH - A clutch including a rotatable member including a first ramp and first teeth, a second member held against rotation, axially displaceable, including a second ramp and second teeth, a spring urging the first and second members apart, and an electromagnet causing the first and second teeth to engage and prevent rotation in a first direction, rotation in a second direction separating the first and second members as the first ramp ascends the second ramp. | 08-28-2014 |
20140374208 | FRICTION BRAKE FOR A DOG CLUTCH - A dog clutch, includes a first ring secured to an overrunning brake rotatable race, including first teeth, a first disc, the second ring angularly displaceable relative to the discs, a non-rotating, axially displaceable second ring including second teeth engageable with the first teeth and a second disc engageable with the first disc, a first spring urging the discs into mutual contact, and a second spring urging the first and second rings apart. | 12-25-2014 |
20150030279 | THRUST BEARING SNAP RING RETAINER - An assembly includes a rotatable member formed with a recess, a first component, a snap ring located in the recess for limiting axial displacement of the first component, and a bearing located between the first component and a second component, including a finger extending from a race of the bearing toward the bearing and able to limit radial movement of the snap ring. | 01-29-2015 |
