A structure promoting a reduction in size and weight of a swing arm structure. Pivot shafts that extend in a vehicle width direction are disposed in the vehicle body frame. A pair of wall portions is disposed in the vehicle width direction in the vehicle body frame. An interposed portion is disposed between the wall portions in the swing arm. The wall portions have wall portion-side pass-through portions, which receive the pivot shafts passed therethrough. The interposed portion has interposed portion-side pass-through portions formed therein at, out of both end portions in the vehicle width direction, portions facing the wall portion-side pass-through portions, respectively. The interposed portion-side pass-through portions receive the pivot shafts, respectively, passed therethrough. The interposed portion has a non-pass-through portion formed therein at least at a middle portion in the vehicle width direction of the interposed portion. The non-pass-through portion does not receive the pivot shafts.

A drive-by-wire steering system on a vehicle requiring counter-steering includes a driver input mechanism, for example, a steering wheel, joystick, voice command receiver, or keyboard, and a control system. A sensor receives driver input and sends that information to the control system. An engagement mechanism, for example, a clutch, separates the driver input mechanism from controlling the vehicle. The control system further includes at least one actuator, a wheel, and a mechanical linkage controllable via the engagement mechanism in order for the control system to articulate a steering mechanism, for example, the front wheel of the vehicle, as appropriate.

In an air intake device for motorcycle, an air cleaner having a front end formed with a main intake port is disposed between a pair of left and right main frame pieces forming a main frame. An introducing passage is formed within the main frame for capturing an incoming wind. An intake air introducing port of the introducing passage is provided at a location rearwardly of the main intake port in the main frame piece. An intake air discharge port is defined in an intermediate portion of a front portion of the main frame with respect to a motorcycle widthwise direction so as to open rearwardly and to be fluid connected with the main intake port. A sub intake port is provided in communication with the main intake port so as to introduce an intake air into the main intake port.

The present disclosure provides systems, methods, and devices for providing stability to a vehicle using one or more auxiliary support members on the vehicle, such as lateral sides of the vehicle. The auxiliary support members may extend away from the vehicle body to approach and/or touch a support surface and provide stability and in some cases additional centripetal force to facilitate steering of the vehicle. The auxiliary support members may also retract towards the vehicle.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

An air-cooled fuel cell-powered motorcycle allowing early detection of a malfunction in a fuel cell stack. The fuel cell-powered motorcycle includes a vehicle body; an electric motor for driving a driving wheel, an air-cooled fuel cell for supplying electric power to the electric motor and a hydrogen tank for storing a fuel gas supplied to the fuel cell, respectively housed in the vehicle body; a fan for supplying air as a reactant and a coolant to the fuel cell; and an exhaust duct for discharging the air having cooled the fuel cell out of a rear end of the vehicle body, the exhaust duct having an inlet connected to a rear end portion of the fuel cell.

An overland trailer is disclosed. In various embodiments, the overland trailer includes a base frame, a trailer body mounted atop the base frame, and a tent assembly mounted atop the trailer body.
