Abstract

Abstract An object of the present invention is to provide a link-type non-pneumatic tire which can reduce the rolling resistance and improve the drive comfort and drivability compare to the solid tire, and also drastically reduce its weight compare to the conventional link-type non-pneumatic tire. The present invention provides a non-pneumatic tire 2 to be mounted to a circular mounting element 3 to form tire/wheel assembly 1 , comprises: a tread 7 disposed outside the mounting element 3 in a tire radial direction and extending in a tire circumferential direction in a state where constituting the tire/wheel assembly 1 ; a plurality of link mechanisms 8 mounded to the mounting element 3 with intervals therebetween in the tire circumferential direction and connecting the tread 7 to the mounting element 3 in such a manner that the tread 7 can move in the tire width direction and radial direction with respect to the mounting element 3 ; and ring-like members 9 L, 9 R extending in the tire circumferential direction and connecting circumferentially adjacent link mechanisms 8 with each other to generate reaction force against a displacement of the tread 7 relative to the mounting element 3.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 127 words
1 . A non-pneumatic tire to be mounted to a circular mounting element to form tire/wheel assembly, comprises: a tread disposed outside the mounting element in a tire radial direction and extending in a tire circumferential direction in a state where constituting the tire/wheel assembly; a plurality of link mechanisms mounded to the mounting element with intervals therebetween in the tire circumferential direction and connecting the tread to the mounting element in such a manner that the tread can move in the tire width direction and radial direction with respect to the mounting element; and ring-like members extending in the tire circumferential direction and connecting circumferentially adjacent link mechanisms with each other to generate reaction force against a displacement of the tread relative to the mounting element.
Claim 2
Dependent Claim 127 words
1 . A non-pneumatic tire to be mounted to a circular mounting element to form tire/wheel assembly, comprises: a tread disposed outside the mounting element in a tire radial direction and extending in a tire circumferential direction in a state where constituting the tire/wheel assembly; a plurality of link mechanisms mounded to the mounting element with intervals therebetween in the tire circumferential direction and connecting the tread to the mounting element in such a manner that the tread can move in the tire width direction and radial direction with respect to the mounting element; and ring-like members extending in the tire circumferential direction and connecting circumferentially adjacent link mechanisms with each other to generate reaction force against a displacement of the tread relative to the mounting element.
Claim 3
Dependent Claim 98 words
2 . The non-pneumatic tire of claim 1 , wherein each the link-mechanism is constituted with a horizontal link bar disposed outside the said mounting element in the tire radial direction and extending along the tire width direction, a pair of right and left inner link arms which are swingablly disposed to said mounting element in a plane along the tire width direction, and a pair of right and left outer link arms swingablly connecting these inner link arms and horizontal link bar, wherein said ring-like members respectively are provided on the pair of the outer link arms.
Claim 4
Dependent Claim 40 words
3 . The non-pneumatic tire of claim 2 , wherein jointing portions between said outer link arms and said inner link arms are respectively located inner side of the ends of said horizontal link bar in the tire width direction.
Claim 5
Dependent Claim 44 words
4 . The non-pneumatic tire of claim 1 , wherein said link mechanism is connected to said mounting element via a torsion spring which generates reaction force against the swing of the link mechanism in the tire circumferential direction relative to said mounting element.
Claim 6
Dependent Claim 34 words
5 . The non-pneumatic tire of claim 1 , wherein a sectional shape of the ring-like member is formed into a laterally long rectangular section in a cross section along the tire width direction.
