  • Patent number: 7267213
    Abstract: A one-way clutch is proposed which is low in surface pressures and durable. It includes an inner ring having a cylindrical outer surface, and an outer ring having a cylindrical inner surface defining a wedge-shaped space in cooperation with the cylindrical outer surface of the inner ring. A ring-shaped wedge member is disposed in the wedge-shaped space. The wedge member is formed with a cylindrical outer surface and a cylindrical inner surface having a center of curvature that is radially offset from the center of curvature of the cylindrical outer surface of the wedge member. A resilient member is provided between the inner ring and the wedge member to bias the wedge member in a direction to be wedged into the narrow portion of the wedge-shaped space. When the inner ring is rotated in one direction, the wedge member will be brought into wedging engagement with the cylindrical surfaces of the inner and outer rings. Torque is thus transferred from the inner ring to the outer ring.

    Abstract: A damper mechanism 6 is provided to transmit torque while absorbing and damping torsional vibrations. A small coil spring 45 achieves characteristics of a low rigidity in a small torsion angle region of the torsion characteristics when compressed by rotary members. A coil spring 33 achieves characteristics of a high rigidity in a large torsion angle region of the torsion characteristics when compressed by the rotary members rotating relatively to each other. A frictional resistance generating mechanism 7 generates a frictional resistance while each spring is being compressed. Owing to a rotating-direction space 79, the frictional resistance generating mechanism 7 does not operate in portions of the second stage of the torsion characteristics in response to vibrations and also does not in the first stage while a torsion angle is in a predetermined range.

  • Patent number: 6536571
    Abstract: A split locking sprag is used as a locking element between an inner race portion and an outer race portion which are moved or driven relative to each other, and has a release linkage that allows the sprag halves to be moved relative to each other to change the combined dimensions of the sprag halves and allow their displacement out of engagement with the inner and outer races. The sprag is divided into two or more sections that pivot about a main pivot pin between locked and unlocked positions. A linkage and tripper mechanism allows the sprag sections to be unlocked in a controlled manner by applying a small external force to the tripper. Alternatively, the sprag can be configured in any manner that allows their combined dimensions to be changed when triggered to release a torque while under load.
