エアレス車輪
Document Type and Number:
Japanese Patent JP7125716
Kind Code:
B2
Abstract:
To provide an airless wheel which suppresses occurrence of slippage even on a soft ground without occurrence of puncture, and is excellent in running performance even on a road surface of a normal asphalt road.SOLUTION: An airless wheel comprises: a tread part 40 comprising plural transverse members 41 which are continuous in a direction crossing a circumferential direction of the wheel and are arranged in the circumferential direction, and connection parts 42 which respectively the transverse members 41 adjacent to each other in the circumferential direction; a pushing part 70 which is positioned on an inner peripheral surface side of the tread part 40, and is pushed toward a radial direction outer side along an inner peripheral curve surface of at least a part of the plural transverse members 41, thereby enabling increase in rigidity of the entire tread part 40; and a rigidity variable part 60 which can change rigidity of the entire tread part 40 by changing the pushing force of the pushing part 70 to the transverse member 41.SELECTED DRAWING: Figure 4
