Abstract

PURPOSE:To reduce horizontal stress and enable horizontal tumbling in a wheel with a tire section for a car and such by comprising a part of the circumferential direction of the tire section with a rotary partial tire around a rim. CONSTITUTION:A tire section 8 is divided comparatively finely in the circumferential direction and duplicate partial tires 4 and 5 are comprised as an aggregate. The partial tire 5 can be rotated in the R direction around an axis A that is almost in parallel to the tangent direction of a wheel rim 3 for the wheel rim 3. The tire section 4 uses a fixed partial tire. As a result of this structure, when the fixed partial tire 4 is grounded, it can be run like a normal wheel, but when the rotary partial tire 5 is grounded, the rotary partial tire 5 rotates and absorbs horizontal external force if it is applied. As a result, horizontal external force can be reduced and horizontal tumbling is enabled in a unit.

The partial tire width in the first group may be fixedly provided to the wheel rim 3 as in the case of conventional wheels, but the partial tire width in the second group is fixed to the wheel rim 3.
In contrast, it is rotatably mounted (arrow R) around an axis A that is approximately parallel to the tangential direction of the wheel rim at that portion. Therefore, in other words, it is possible to rotate around an axis A that is substantially orthogonal to the wheel rotation axis.

Therefore, for example, if the present invention is applied to one of the front wheels of a four-wheeled vehicle, the lateral force that acts on the wheel because the wheels are not parallel to each other will be absorbed, reducing tire wear. be able to. In addition, when this wheel is used not only for vehicles but also for the rear wheels or follower wheels of self-propelled robots, the wheels may roll laterally due to rolling friction due to the lateral force acting on the wheels due to the slope of the road surface. As a result, the vehicle body or robot can automatically descend in the direction of the valley, and this action enables automatic travel along the valley or depression.
