  • Patent number: 10788099
    Abstract: A torsional vibration damper in which a noise resulting from collision of an inertia body against a rotary member is reduced. An inertia body is arranged coaxially with the rotary member, and rolling members are interposed between the rotary member and the inertial body to transmit torque of the rotary member to the inertia body. A first clearance between an outer circumference of a rotary member and an inner circumference of the inertia body created when rolling members are centrifugally pushed onto raceway surfaces is identical to or narrower than a second clearance between one of the rolling members situated at a highest level and a bottom surface of a guide section.

    Abstract: A torque converter oil cooling system includes an air-oil cooler system that is adapted to be disposed between a torque converter charging oil outlet and charging oil inlet. The torque converter oil cooling system has a controller that directs oil when at a predetermined temperature to pass through an air oil cooler for cooling and then directs the cooled oil back to the inlet of the torque converter for torque converter operation. The torque converter oil cooling system normally operates in the non-lockup mode operation of the torque converter. Using the torque converter oil cooling system permits a vehicle to continuously operate in a torque converter mode for an extended period of time, which becomes extremely helpful when the vehicle is called upon to haul heavy loads over steep grades.

    Abstract: When a butting control is performed at a low temperature at which an oil temperature of an automatic transmission is equal to or lower than a predetermined value, a driving condition changing process is performed. In the driving condition changing process, an execution period from a starting of the butting control to an ending of the butting control is divided into a plurality of sections on the basis of a rotation angle of a motor. By making a torque of the motor greater and a rotation speed higher in a starting-section than in an ending-section, the execution period of the butting control is made short. By making the torque of the motor smaller and the rotation speed lower in the ending-section than in the starting-section, an amount of deformation of a component is made smaller when a part of a component is butted against a limit position so that a reference position can be learned accurately.

  • Patent number: 9051977
    Abstract: The lock-up device includes: a clutch part disposed between a front cover and a turbine; and a damper mechanism for transmitting torque from the clutch part to the turbine and for absorbing and attenuating a torsional vibration. The damper mechanism includes: an input plate into which torque is inputted from the clutch part; an output plate connected to the turbine; a plurality of torsion springs; an intermediate member; and a restriction member. The intermediate member is rotatable relatively to the input plate and the output plate, and causes two torsion springs to act in series. The restriction member is mounted to the input plate, and restricts the intermediate member from moving in both of an axial direction and a radial direction.
