  • Patent number: 11554657
    Abstract: A driving device includes: an internal combustion engine; a first rotating electric machine; a second rotating electric machine; and a transmission. The transmission includes: a first rotating electric machine shaft; a second rotating electric machine shaft which is arranged in parallel to the first rotating electric machine shaft; a first gear provided in the first rotating electric machine shaft; and a second gear provided in the second rotating electric machine shaft. A width in an axial direction of the first rotating electric machine is larger than that of the second rotating electric machine. The number of gears provided in a shaft in which a gear for the first rotating electric machine that meshes with the first gear is arranged is smaller than the number of gears provided in a shaft in which a gear for the second rotating electric machine that meshes with the second gear is arranged.

  • Publication number: 20210252962
    Abstract: An apparatus includes a generator, a case, a first bearing configured to rotatably support a rotating shaft of the generator on a side of one end portion, and a second bearing configured to rotatably support the rotating shaft on a side of the other end portion. The case includes a first wall portion that forms an accommodation space, and a second wall portion that covers an end portion of the first wall portion. The first bearing is supported by the second wall portion. The rotating shaft includes an input portion on a side of the other end portion of the second bearing, and a transmission portion configured to transmit, to the second bearing, a thrust load of the rotating shaft acting from the other end portion toward the one end portion.

  • Patent number: 8443856
    Abstract: The present invention realizes a pneumatic tire for a motorcycle, in which durability in running straight at a relatively high speed and tread surface gripping properties during high-speed cornering are made compatible and, in particular, a pneumatic tire for a motorcycle, which tire is capable of demonstrating appropriate durability and driving stability in accordance with inputs even if these inputs differ between running straight, cornering left and cornering right. The tread portion 3 is constituted of plural types of rubbers 11-13 adjacent to each other in the tire widthwise direction and sectioned into at least a center region A at the center portion of the tire including the tire equatorial plane and two side regions B1, B2 at respective sides of the tire.

  • Patent number: 6371183
    Abstract: A pneumatic tire comprises at least one carcass ply of textile cords and a belt comprised of two cross belt layers containing textile cords arranged at a cord inclination angle of 10-45° with respect to the equatorial plane, in which a difference of cord inclination angle between the two cross belt layers with respect to the equatorial plane of the tire is within a range of 5-35° in the widthwise direction, and is mounted onto at least either left-side or right-side front wheel of a four-wheeled vehicle.

  • Patent number: 5443105
    Abstract: The pneumatic radial tire of the invention has a pair of bead portions each containing a bead core therein and is characterized in that each bead core is substantially constructed by winding at least one metal wire, and a bead toe reinforcing rubber stock with a JIS A hardness of 80.degree.-98.degree. is arranged inward of the outer edge of each bead core in an axial direction of the tire. In each bead portion the width of the bead toe reinforcing rubber stock is in a range of 0.5-2.0 times the width of the bead core in the axial direction. In each bead portion the width from the outer edge of the bead core to the inner edge of the bead portion in the axial direction of the tire is in a range of 1.1-3.0 times the width of the bead core in the axial direction of the tire.
