20090078525 | Method and Apparatus For Limiting Wheel End Clutch Ring Travel - A travel limiter associated with a wheel end adapted to selectively engage and disengage a drive shaft via a sliding clutch ring. The travel limiter operatively disposed on a coupler of the wheel end and configured to limit axial displacement of the sliding clutch ring towards the wheel assembly when engaging the drive shaft. | 03-26-2009 |
20120083380 | MULTI-MODE DRIVE SYSTEM FOR TRANSAXLE APPLICATIONS - A vehicle drive system capable of selectively providing all-wheel drive and single-driven-axle modes includes a front drive unit having a planetary gearset with a grounded ring gear and a sun gear driven by the transaxle's drive spool via an input shaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby selectively provide both an available low range and a front axle disconnect. The front drive unit further defines a power take-off unit with a clutch selectively coupling the input shaft to a propshaft. The rear drive unit includes a planetary gearset with a grounded ring gear, a sun gear driven by the propshaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby likewise selectively provide both an available low range and a rear axle disconnect. | 04-05-2012 |
20120108379 | HYBRID TRANSMISSION - A multi-speed hybrid transmission includes a main gearset connected to a vehicle gas combustible engine and providing torque to an output shaft. The transmission also includes an electric drive unit comprising an electric motor that is selectably connectable to the output shaft to provide additional torque to the output shaft. When connected to the output shaft, the electric drive unit improves vehicle performance under certain driving conditions (e.g., high boost in low gear or in upper gears) while also improving fuel efficiency. | 05-03-2012 |
20130151093 | METHODS AND SYSTEM FOR USING VEHICLE LONGITUDINAL ACCELERATION FOR TRANSMISSION CONTROL - A method and system of improving shift event performance in a vehicle with an automatic transmission. One or more accelerometers in the vehicle are used to sense one or more longitudinal acceleration values. The longitudinal acceleration values or values derived therefrom are compared with predetermined stored values. Shift event behavior is changed in response to differences between the one or more longitudinal acceleration values or values derived therefrom and the predetermined stored values. | 06-13-2013 |

20080230296 | Front to Rear Torque Vectoring Axle with Overspaced Capability for Vehicle Dynamic Control Systems - A torque bias coupling ( | 09-25-2008 |
20080252030 | VEHICLE CORNER MODULE - A corner module for an automotive vehicle includes a suspension upright, a wheel end, and a CV joint. The wheel end has a housing that is secured to the suspension upright and a hub that is provided with a flange to which a road wheel is attached and also spindle that projects from the flange into the housing. In addition, the wheel end has a tapered roller bearing located between the housing and the hub spindle. The CV joint drives the hub through a coupler ring or an inboard bearing cone that fits around and is engaged with the hub spindle, all through mating splines. The CV joint may have a stub shaft that projects from the bell through the hub spindle to clamp the CV joint and hub spindle together. Torque is transferred to the hub spindle at a large diameter through the bell of the CV joint. When present, the stub shaft serves merely to hold the CV joint and hub spindle together and thus may exist at a small diameter. Because the bearing transfers radial and thrust loads through tapered rollers, it and the wheel end of which it is a part may exist in configurations smaller than their counterparts in traditional wheel ends. | 10-16-2008 |
20080298732 | Unitized Single Row Bearing with Reverse Thrust Capabilities - An antifriction bearing A capable of transferring radial loads as well as thrust in both axial directions. The bearing A comprises an outer race ( | 12-04-2008 |
20090051214 | VEHICLE WHEEL END ASSEMBLIES AND METHODS OF ASSEMBLY THEREOF - A wheel end assembly for a vehicle includes an axle tube and a housing secured to the end of the axle tube. A hub includes a drive flange located beyond the housing and a spindle projecting from the drive flange into the housing. The hub spindle has a substantially solid body with drive splines about an external surface of the spindle. Rolling elements are located between the hub spindle and the housing for enabling the hub to rotate about an axis. An axle shaft is positioned within the axle tube and includes splines that are coupled to the external drive splines of the hub. | 02-26-2009 |
20090080824 | BEARING HAVING THERMAL COMPENSATING CAPABILITY - A roller bearing for use in transmission cases ( | 03-26-2009 |
