Strandlike Locking Member (e.g., Wire, Etc.) Patents (Class 474/221)
  • Patent number: 8002658
    Abstract: A power transmission chain includes a plurality of links and a bending-restraining mechanism. The bending-restraining mechanism includes a wire extending in a lengthwise direction along the chain and engaging at least three adjacent joints of the chain. The wire is formed such that it elastically deforms when an inside link rotates around the inner joint in a first direction from a linearly extending state, the wire thereby applying a bending resistance to the inside link during articulation of the chain. In one embodiment, the wire includes at least one curved section clipped around at least a majority of a circumference of at least one joint. In another embodiment, the wire is formed such that a predetermined bias due to a bending deformation of the wire is applied to the inside link when the chain is extended linearly.

  • Publication number: 20030186767
    Abstract: A drive chain suitable for use in a continuously variable transmission of a motor vehicle, the transmission having two pairs of spaced drive members about which the chain passes to transfer torque from one drive member to the other. The chain includes a plurality of link elements that include spaced, side-by-side plate links. The plate links include openings in which pairs of parallel rocker members are disposed for relative rocking movement of at least one rocker member about its longitudinal axis. The rocker members extend outwardly beyond the plate links and are retained in position by retaining members that engage particular rocker members. A method for stretching the chain is also disclosed in which areas of some of the plate links are plastically deformed before the chain is put to use.

  • Patent number: 6311469
    Abstract: A drive chain has opposed pairs of inner link plated that are interconnected by cast outer links. Pins pass through aligned apertures in overlapping end portions of the inner and outer links. Each pin is fixed relative to the inner link. The outer link has open or blind bores that receive end portions of the pins in a pivotal relationship. A bearing area is defined between the outer surface of the pin and an inner surface of the outer link bore. The provision of a bearing area in the outer link makes maintenance and sealing easier.
