Abstract
A tire-wheel assembly comprises a wheel coupled to a rotating shaft; an elastic tube disposed on an outer side of the wheel with respect to a radial direction, the interior of the tube being filled with air; a rigid protective ring disposed on an outer side of the tube with respect to the radial direction separated from the wheel; and a tread ring disposed on an outer side of the protective ring with respect to the radial direction, an inner circumferential surface of the tread ring contacting an outer circumferential surface of the protective ring.

A tire-wheel assembly comprising:
- a wheel coupled to a rotating shaft;
- an elastic tube disposed on an outer side of the wheel in a radial direction, an interior of the tube being filled with air;
- a rigid protective ring disposed on an outer side of the tube in the radial direction so as to be separated from the wheel;
- and
- a tread ring disposed on an outer side of the protective ring in the radial direction, an inner circumferential surface of the tread ring contacting an outer circumferential surface of the protective ring;
- wherein
- through-holes that penetrate from the inner circumferential surface to an outer circumferential surface of the tread ring are formed in the tread ring;
- inner circumferential surface grooves that are concave with respect to the outer circumferential surface of the tread ring are formed in the inner circumferential surface of the tread ring;
- the inner circumferential surface grooves are connected with the through-holes;
- and
- the inner circumferential surface grooves extend from one end of the inner circumferential surface to another end of the inner circumferential surface in a width direction of the inner circumferential surface that is parallel to a central axis.
An annular tread ring formed from an elastic member, and comprising an inner circumferential surface that contacts a ring-shaped rigid member and an outer circumferential surface that contacts ground, the tread ring comprising:
- through-holes formed in the tread ring that penetrate from the inner circumferential surface to the outer circumferential surface;
- wherein
- inner circumferential surface grooves that are concave with respect to the outer circumferential surface are formed in the inner circumferential surface of the tread ring;
- the inner circumferential surface grooves are connected with the through-holes;
- and
- the inner circumferential surface grooves extend from one end of the inner circumferential surface to another end of the inner circumferential surface in a width direction of the inner circumferential surface that is parallel to a central axis.
