  • Publication number: 20200172192
    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: 9969454
    Abstract: A load transmission includes a left foot placement surface on which a left foot of a driver riding the vehicle is to be placed and a right foot placement surface on which a right foot of the driver is to be placed. The load transmission transmits a load to a left portion of a linkage by way of the left foot placement surface, and transmits a load to a right portion of the linkage by way of the right foot placement surface.

  • Patent number: 9771118
    Abstract: A vehicle includes a steering force transmission including a steering force input, a steering shaft that is connected to the steering force input and which is supported by a first shaft support so as to turn about a rear steering axis, a connector that is connected to the steering shaft and displaced as the steering shaft turns, and a relay shaft that is connected to the connector to turn about a front steering axis as the connector is displaced, which is supported by a second shaft support that is provided ahead of the first shaft support to turn a right front wheel and a left front wheel as the second shaft support turns. The first shaft support is fixed to a portion of a body frame that extends to the rear from the link support so that the rear steering axis of the steering shaft is disposed behind a movable range of a rear cross element of a linkage in relation to a front-and-rear direction of a middle upper axis.
