  • Patent number: 11305832
    Abstract: A left suspension unit supports a left wheel. A right suspension unit supports a right wheel. A steering actuator imparts a force causing the left suspension unit and the right suspension unit to turn about a left steering axis and a right steering axis respectively to a steering force transmission mechanism. A leaning actuator imparts a force causing a body frame to lean leftward or rightward of a leaning vehicle to a link mechanism. A control unit is capable of selecting a first mode wherein both of the steering actuator and the leaning actuator are employed, and a second mode wherein the steering actuator is employed without employing the leaning actuator, in order to control a leaning angle of the body frame in cooperation with a steering mechanism.

  • Patent number: 10167043
    Abstract: A vehicle includes a right front wheel, a left front wheel, a brake operator, grips, and a steering force transmission which transmits a steering force to the right front wheel and the left front wheel. The steering force transmission includes a steering shaft, a handlebar, and a tie rod. Brake operators, which operate the brakes, and the grips are located on the handlebar, and a rubber damper located on the steering force transmission significantly reduces or prevents vibrations from being transmitted to the grips, wherein the vibrations are due to a difference between a frictional force generated between the right front wheel and a corresponding road surface and a frictional force generated between the left front wheel and a corresponding road surface.

  • Patent number: 9493208
    Abstract: A vehicle prevents interference of a right lamp and a left lamp with a link mechanism without increasing the size of the vehicle in its width direction. A right link side portion of a right lamp is located on the right of a locus along which a link mechanism extends when an upper cross portion turns when looking at the vehicle from the front of an upper middle axis. At least a portion of the right link side portion is located on the left of a right end portion of a body cover, above the upper middle axis, and below an upper end portion of the link mechanism that results when the upper cross portion turns clockwise to a maximum extent relative to a body frame, when looking at the vehicle from the front of the upper middle axis.
