  • Patent number: 9958055
    Abstract: An automatic transmission (1) includes first, second, and third planetary gear sets (10, 20, 30) and a lubricant feed passage (L2). The first and second planetary gear sets (10, 20) form a two-stage planetary gear set (40). The third planetary gear set (30) is adjacent to the two-stage planetary gear set on one axial side of the automatic transmission. The lubricant feed passage (L2) feeds a lubricant to a bearing (25) of the second planetary gear set located on an outer periphery of the two-stage planetary gear set (40). The lubricant feed passage feeds the lubricant from a first inlet (37e) to the bearing via a first oil passage (37f) and oil passages (26a, 26b, 26c) in a pinion shaft. The first inlet (37e) is formed on a side of a carrier body (37) opposite to the two-stage planetary gear set and on an inner periphery of the automatic transmission.

    Abstract: A friction drive arrangement includes a plurality of interleaved rotor and stator discs. An end stator disc is adjacent a reaction plate containing a plurality of cylindrical, stepped bores defining spring receptacles opening toward the end stator disc and pin guide holes opening in an opposite direction. Each receptacle contains a coil compression spring located between a bottom of the receptacle and a spring retention pin having a first end section reciprocably received in the guide hole and having a second end section defined by a large diameter foot located between an end of the spring and the end stator disc, with the foot being configured for directly engaging the end stator disc. A tool is used to retract the pins and associated springs into the associated receptacles so as to retain the springs during assembly. Excess retraction of the pins is prevented for preventing over-compression of the springs.

  • Patent number: 9879774
    Abstract: An output shaft of a transmission is fixed to a planetary gearset carrier. Output torque is measured via a surface acoustic wave sensor affixed to a face of the carrier between two adjacent planet gears and radially inside a weld joining the carrier face to an opposite carrier face. In this location, the level of strain at typical transmission output torques produces a level of strain within the measuring range of a surface acoustic wave sensor. The sensor may be powered and signals communicated across an air gap defined by signal rings. Due the stable position and orientation of the carrier, a small, consistent air gap is possible.

  • Patent number: 9869383
    Abstract: A reduction gear of the present invention is compact and light and can be used for tire portions of an apparatus for travelling, etc. Each of outer and inner pins is formed by a rolling bearing. The reduction gear includes block-shaped lubricating members which supply a lubricant to the outer rings of the outer pins to thereby lubricate them, and a ring-shaped lubricating member which supplies the lubricant to the outer rings of the inner pins to thereby lubricate them. The lubricant can be supplied to a pair of cycloid gears through the outer pins and the inner pins for lubrication. Since the cycloid gears, the outer pins, and the inner pins are lubricated by the lubricating members, the reduction gear can enhance its durability, reduce the friction between components to thereby lower the frictional resistance, and realize a light and compact structure.
