  • Patent number: 11346409
    Abstract: A vehicle transmission includes a shaft; speed-changing gears; switching mechanisms; and a shifting mechanism. The shifting mechanism is provided with a double-meshing preventing mechanism configured to switch between a one-way state in which the switching mechanisms are hindered from moving in a downshift direction and allowed to move in an upshift direction and a free state in which the switching mechanisms are allowed to move in both the downshift direction and the upshift direction.
    Type: Grant

  • Patent number: 11168741
    Abstract: A dog clutch for a vehicle includes gear-side meshing teeth provided on a shifting gear fitted so as to be rotatable relative to a shaft, and a dog ring disposed adjacent to the shifting gear in the axial direction of the shaft. The dog ring includes a first ring, a second ring, and springs interposed between the two rings. The first ring is provided with meshing teeth that can be meshed with the gear-side meshing teeth of the shifting gear. The second ring is provided with meshing teeth that can be meshed with the gear-side meshing teeth of the shifting gear. The springs are provided on the inner peripheral side of a circle that is centered on a rotational axis and that circumscribes a portion of the meshing teeth of the first ring and the second ring positioned on the outermost peripheral side.
