Abstract
A four-wheel traveling device having a new steering mechanism performs steering by converting an extending/retracting motion of one linear actuator into rotational motion in the horizontal plane of a first front wheel, a second front wheel, a first rear wheel, and a second rear wheel via a link, wherein the linear actuator extends and retracts parallel to a line connecting the first front wheel and the second front wheel.
Claims12
A four-wheeled traveling device that performs steering by converting extension and contraction motion of one linear actuator into rotational motion of a first front wheel, a second front wheel, a first rear wheel, and a second rear wheel in a horizontal plane via a link, wherein
- the linear actuator extends and contracts in parallel with a line connecting the first front wheel and the second front wheel.
A four-wheeled traveling device that performs steering by converting extension and contraction motion of one linear actuator into rotational motion of a first front wheel, a second front wheel, a first rear wheel, and a second rear wheel in a horizontal plane via a link, wherein
- at least two of a link for the first front wheel, a link for the second front wheel, a link for the first rear wheel, and a link for the second rear wheel have an identical shape.
A four-wheeled traveling device that performs steering by converting extension and contraction motion of one linear actuator into rotational motion of a first front wheel, a second front wheel, a first rear wheel, and a second rear wheel in a horizontal plane via a link, wherein
- a link for the first front wheel and a link for the first rear wheel are located substantially on a first horizontal plane and rotate in the first horizontal plane,
- a link for the second front wheel and a link for the second rear wheel are located substantially on a second horizontal plane and rotate in the second horizontal plane, and
- the first horizontal plane and the second horizontal plane are different from each other.
