  • Publication number: 20100192724
    Abstract: A power transmission device has a first shaft adapted to be driven by a power source. A second shaft is adapted to transmit torque to a driveline. A transfer unit is selectively operable to transmit torque between the first and second shafts. The transfer unit includes a first sprocket that is rotatably supported on one of the first and second shafts, a second sprocket that is fixed for rotation with the other of the first and second shafts, and a flexible member that drivingly interconnects the first and second sprocket. A clutch is selectively operable to drivingly interconnect the first sprocket and one of the first and second shafts such that drive torque is transferable from the first shaft to the second shaft. The clutch is controlled by a clutch actuation system having an actuator that is at least partially positioned within a volume defined by the flexible member.

  • Publication number: 20080004149
    Abstract: A drive axle assembly includes first and second axleshafts connected to a pair of wheels and a drive mechanism operable to selectively couple a driven input shaft to one or both of the axleshafts. The drive mechanism includes a differential, a speed changing unit operably disposed between the differential assembly and the first and second axleshafts, first and second mode clutches and a brake unit. The first mode clutch is operable to increase the rotary speed of the first axleshaft which, in turn, causes a corresponding decrease in the rotary speed of the second axleshaft. The second mode clutch is operable to increase the rotary speed of the second axleshaft so as to cause a decrease in the rotary speed of the first axleshaft. The brake unit is operable to engage the speed changing unit. A control system controls actuation of both mode clutches.

  • Publication number: 20070244184
    Abstract: The compounds of the present invention relate to chain-extended and chain-modified analogues of salacinol, including embodiments where the sulfate moiety has been substituted with a carboxylate or phosphate moiety. In other embodiments the sulfate moiety has been shifted by one carbon atom in the zwitterionic structure. In another embodiment the polyhydroxylated side chain may be replaced with a lipophilic alkyl chain and a suitable counterion. The invention also encompasses methods for synthesizing the salacinol analogues and using the analogues for enzyme inhibition applications.

  • Publication number: 20070056826
    Abstract: A vehicle includes an engine that generates drive torque and a power transfer device that selectively transfers the drive torque to a driveline. The power transfer device includes an input shaft, an output shaft and a torque biasing system. The torque biasing system has a clutch pack and an actuator that regulates engagement of the clutch pack. An on-demand lubrication system supplies a lubricating fluid flow through the clutch pack based on a control signal generated by a control system. A passively actuated positive displacement pump supplies the lubricating fluid flow through the clutch pack based on a speed differential between the input shaft and the output shaft.

  • Publication number: 20060231368
    Abstract: A torque transfer mechanism for controlling the magnitude of a clutch engagement force exerted on a clutch pack that is operably disposed between a first rotary member and a second rotary member includes a hydraulic clutch actuation system. The hydraulic clutch actuation system includes a primary fluid circuit coupled to a secondary fluid circuit by a pressure intensifier. The pressure intensifier provides magnified pressure to a piston for actuating the clutch pack.

  • Publication number: 20060173603
    Abstract: A method is provided for reducing slip loss experienced by the tires of a vehicle. The method includes: determining a longitudinal force associated with each tire; determining an optimal slip coefficient for each tire based in part on the corresponding longitudinal force for the tire; and determining a torque to be applied to each tire based in part on the optimal slip coefficient, thereby reducing the slip loss experienced by the tires of the vehicle. This method is typically employed in the absence of other control algorithms used by a vehicle's traction control system.
