    Abstract: A torsional vibration reducing apparatus is provided. The torsional vibration reducing apparatus includes a rotating body having a rolling chamber, and a rolling body including a support shaft portion, a first flange portion, a second flange portion, a first corner portion, and a second corner portion. The support shaft portion is housed in the rolling chamber. The flange portions are located respectively at either end of the support shaft portion in an axial direction. A position defined by the support shaft portion and the first flange portion is the first corner portion, and a position defined by the support shaft portion and the second flange portion is the second corner portion. In a section of the rolling body that is along a central axis of the support shaft portion, sectional shapes of the first corner portion and the second corner portion differ from each other.

    Abstract: A soundproofing device for a transmission according to the present disclosure is provided to transmit the power of one or more prime movers (for example, internal combustion engine and electric motor). The soundproofing device includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and an opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with the outside of the Helmholtz resonance chamber. The wall includes a transmission case that accommodates the transmission and a housing of a component mounted on the transmission (for example, PCU housing). The Helmholtz resonance chamber is formed between the transmission case and the housing.

    Abstract: A soundproofing device according to the present disclosure includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and a first opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with an outside of the Helmholtz resonance chamber. At least a part of the wall is configured by a sound source member that radiates sound. The Helmholtz resonator includes: one or more partition walls formed so as to divide the Helmholtz resonance chamber into a plurality of regions, and a second opening formed in the one or more partition walls so as to cause the plurality of regions to communicate with each other.

    Abstract: There is provided a vibration damper which is capable of damping torsional vibrations by pendulum movement of a plurality of inertial masses, and damping vibrations of plurality of order without letting the inertial masses to interfere.A distance between a center of curvature of an inner surface of a first through-hole and a center of curvature of an inner surface of a second through-hole formed in a rotary member is shorter than a distance between a center of curvature of an inner surface of a fifth through-hole and a center of curvature of an inner surface of a sixth through-hole formed in a first inertial mass. Moreover, a distance between a center of curvature of an inner surface of a third through-hole and a center of curvature of an inner surface of a fourth through-hole in a rotary member is longer than a distance between a center of curvature of an inner surface of a seventh through-hole and a center of curvature of an inner surface of an eighth through-hole formed in a second inertial mass.

    Abstract: A control system for a meshing type engagement mechanism includes a meshing type engagement mechanism and an electronic control unit. The electronic control unit is configured to allow a fluid chamber to be filled with a fluid by putting a switching valve into a cut-off state after respective dog teeth mesh with each other by a second member reaching a predetermined position determined in advance in response to a fluid pressure of the fluid chamber such that the second member is pressed in the direction in which the second member is separated from a first member by a release force depending on the torque transmitted between a surface of a first tooth and a surface of a second tooth, the fluid pressure of the fluid chamber is increased, and an engagement state between the first member and the second member is maintained by the fluid pressure which is increased.
