  • Publication number: 20230192216
    Abstract: A vehicle includes an upper frame, a lower frame, a front frame, a rear frame, a pair of rear wheels, a drive motor to drive the pair of rear wheels, a battery supported by the upper frame and the lower frame to supply electric power to the drive motor, a straddled seat at a higher position than the drive motor, and a bar handle at a higher position than the straddled seat. The battery includes a battery lower portion and a battery upper portion. The battery upper portion includes a projection that overhangs in at least a horizontal direction with respect to the battery lower portion. At least a portion of the drive motor is below or directly below the projection.

  • Patent number: 11603157
    Abstract: A vehicle includes an engine, at least three wheels including a front wheel and a rear wheel, a fuel tank above the engine, a seat rearward of the fuel tank, a canister positioned lower than the fuel tank, and a vent hose to supply air therethrough into the canister to desorb the adsorbed fuel evaporative emission from the canister. An upstream end of the drain hose is connected to the vent hose. A downstream end of the drain hose is positioned lower than the canister.

  • Patent number: 11142033
    Abstract: A front suspension structure of a vehicle where an appropriate locus of a front wheel when going over undulating ground, an arm span, and an arm length can be secured. Left and right first arms are rotatable about a rotation axis extending forward and obliquely toward a center in a left-right direction in a plan view and passing through two proximal parts. A frame front section has left and right front coupling parts to which proximal parts of front rods of left and right upper arms are coupled respectively. A distance between the left and right front coupling parts is smaller than a width in a left-right direction of a housing of a differential gear.

  • Patent number: 11014420
    Abstract: A vehicle that can reduce change in the toe angle of a rear wheel in a toe-out direction at the time of a braking force being provided by the vehicle. A coupling point between a vehicle frame and a trailing arm is defined as a first coupling point. A coupling point between the trailing arm and a lateral arm is defined as a second coupling point. A coupling point between the lateral arm and a frame rear section is defined as a third coupling point. A straight line connecting the first coupling point and the second coupling point is defined as a first straight line. A straight line connecting the second coupling point and the third coupling point is defined as a second straight line. With those definitions, an angle between the first straight line and the second straight line in a plan view of the vehicle is 90 degrees or greater.
