  • Publication number: 20160032979
    Abstract: In a bearing according to an embodiment, a pair of magnets is arranged such that sides of the magnets opposed to each other with rolling members interposed therebetween have different magnetic polarities from each other. A magnetic fluid sealed bearing according to another embodiment includes a non-magnetic spacer disposed between a magnet of one of magnetic fluid seals and a magnet of the other of the magnetic fluid seals so as to form a magnetic circuit that penetrates outer and inner rings and goes around the rolling members.

  • Publication number: 20160032983
    Abstract: A drive shaft assembly is formed from two concentrically arranged driveshafts fastened together near to one end of the driveshaft assembly so as to prevent relative rotation therebetween and connectable together near to an opposite end via a torque sensitive drivable connection. The torsional stiffness of the driveshaft assembly is primarily dependent upon whether one or both driveshafts are arranged to transmit torque. The drivable connection may be a mechanical lost motion connection which is operable to either connect the two driveshafts together or not based upon the magnitude of torque applied to the driveshaft assembly. Therefore, the driveshaft assembly provides more than one torsional stiffness allowing it to be better optimized to meet differing operational requirements.

    Abstract: A power transfer case (10) transfers drive torque from the input member to the output member. The power transfer case (10) includes a lubrication system (18), a hydraulically actuated friction clutch assembly (12), and a hydraulically actuated range shift assembly (14). An on-demand electric lube pump (16) can supply a fluid under pressure. An accumulator (20) is selectively supplied with fluid under pressure from the on-demand lube pump (16). A first valve (22) selectively directs fluid under pressure from the on-demand lube pump (16) to the lubrication system (18) when in a first position (22a) and to the accumulator (20) when in a second position (22b). A second valve (28) selectively directs fluid under pressure from the accumulator (20) to the range shift assembly (14) when in a first position (28a), to the friction clutch assembly when in a second position (28b), and isolates the accumulator (20) from the range shift assembly (14) and the friction clutch assembly (12) when in a third position (28c).
