  • Patent number: 7922615
    Abstract: A transfer case is provided with a range unit, an interaxle differential, a clutch assembly and a power-operated actuation mechanism. The range unit includes a planetary gearset driven by an input shaft, and a synchronized dog clutch assembly for releasably coupling one of the input shaft or an output component of the planetary gearset to an input member of the interaxle differential. The interaxle differential further includes a first output member driving a first output shaft, a second output member operably driving a second output shaft. The clutch assembly is a multi-plate friction clutch operably disposed between the first and second output shafts. The power-operated actuation mechanism includes a range actuator assembly, a clutch actuator assembly and a motor assembly operable to control coordinated actuation of the range actuator assembly and the clutch actuator assembly.

  • Patent number: 6684994
    Abstract: An electrostatic unit for location of members of mechanical devices includes a housing of the electrostatic location unit, a locating member arranged in the housing and movable from one position to another, an electrostatic location apparatus for location of the locating member in one of the positions, placed in the housing and including two electrically conductive members and a layer of a dielectric therebetween, conformal surfaces of the electrically conductive members and the dielectric for electrostatic interaction and location of one relative to the other when they are in close proximity to each other and an electric charge is applied to the electrically conductive members. At least one of the members of the electrostatic location apparatus includes a layer of an elastic material on a conformal surface.
