20080254900 | Axial lash control for a vane-type cam phaser - A camshaft phaser for varying the timing of valves in an internal combustion engine. A rotor includes a plurality of vanes disposed in a stator having a plurality of lobes, forming a plurality of alternating timing advance and timing retard chambers. Pressurized oil is supplied selectively to the chambers to change the phase angle of the camshaft with respect to the crankshaft. The rotor is captured between a stator plate and a rotor cover plate. Axial surfaces of the rotor form wiping surfaces with their respective plates. The rotor is divided equatorially into two interlocking sections, the lower section riding on the stator plate and the upper section riding on the cover plate. An axially slidable labyrintian seal formed at the juncture of the upper and lower sections prevents oil leakage. A lash spring between the upper and lower sections urges the sections into zero-lash with their respective plates. | 10-16-2008 |
20090017920 | Front cover for a vane-type cam phaser - A die cast aluminum front cover plate for application in a vane-type camshaft phaser includes a plurality of bores and a plurality of steel threaded inserts press fitted into the bores. Steel threaded inserts add the required strength to the stator bolt threads to enable a shorter thread engagement, which in turn enables a thinner aluminum front cover plate that may be packaged in tight applications where prior art aluminum front covers cannot be used due to their larger thickness. The steel threaded inserts not only provide a higher stiffness but also have a flanged shape that effectively spreads the clamp load generated during the tightening of the stator bolts further out preventing local clamp load points and, consequently, reducing cover deflection over the span of the front cover plate. | 01-15-2009 |
20090069097 | Cam phaser having pre-loaded spring for biasing the rotor through only a portion of its range of authority - During assembly of an improved phaser, a rotor bias spring is captured by a spring retainer that is fitted or formed into the cover, allowing the spring to be installed in a pre-load position and forming a sub-assembly that is then attached to the remaining components. Grounded and active spring tangs are captured in separate slots in the spring retainer. A pocket within the rotor receives the active tang of the bias spring. The pocket has a tapered bottom ramp that lifts the active tang from the slot wall in the retainer and positions the active tang within the pocket in a retarding direction. Lifting the active tang of the bias spring prevents friction between the spring and the retainer slot wall as would occur as the rotor moves in a retarded direction. In advancing, spring rotation stops when the active tang contacts the end of the retainer slot. | 03-12-2009 |

20130172091 | BALL TYPE CONSTANT VELOCITY JOINT - A constant velocity joint including an outer race including a plurality of outer race ball grooves on an internal surface thereof; an inner race arranged inside the outer race and including a plurality of inner race ball grooves on a peripheral surface thereof; a plurality of balls respectively received in the outer and inner race ball grooves for transmitting a torque between the outer race and the inner race; and a cage arranged between the outer and inner races and including a plurality of window portions that respectively receive balls in a circumferential direction thereof. On at least one of a plurality of groove wall protrusions that are configured by sidewall surfaces of the inner race ball grooves adjoining cutouts are respectively formed on axially opposite sides of an inner race on a peripheral side of the inner race. | 07-04-2013 |
20140141895 | INNER RACE AND BOOT SLEEVE - An inner race and boot sleeve combination is provided. The inner race has an inner surface with a groove formed therein. The boot sleeve has a groove in an outer surface. A ring is located in both grooves to axially secure the inner race and boot sleeve together. Devices to prevent relatively rotation between the inner race and the boot sleeve are also provided. | 05-22-2014 |

20120077602 | AXIALLY ADJUSTABLE DRIVESHAFT ASSEMBLY - An axially adjustable driveshaft assembly in a drive train system is described. Two hollow driveshaft sections, where one has a valve through an aperture in it and each has an end fitting, engage each other to form an axially adjustable driveshaft assembly that has a sealed internal chamber within. When a pressurized air or vacuum source is connected to the valve, air fills the chamber or air is removed from the chamber, which correspondingly increases or decreases a drive train system length. This results in facilitating the installation of the driveshaft assembly between a transmission and an axle assembly in a drive train system. | 03-29-2012 |

20140051525 | SHAFT POSITIONING DEVICE - A shaft positioning device is provided. The shaft positioning device includes a first supporting part, a second supporting part, and a position-limiting structure. The first supporting part includes a first hole. The second supporting part includes a second hole. After two ends of a shaft are penetrated through the first hole and the second hole, respectively, the position-limiting structure is located beside the first supporting part to limit the axial position of the shaft. Consequently, the shaft positioning device of the present invention is capable of positioning various types of shafts without the need of reserving a large installation space. | 02-20-2014 |
