Document Type and Number:
WIPO Patent Application WO/2005/118312
Kind Code:
A1
Abstract:
An elastic wheel and a method of manufacturing the elastic wheel. The elastic wheel, comprising a circumferentially extending rim (3) pivotally supporting a tire, a disk (5) fixed to an axle, and a connection means elastically connecting the rim to the disk. The connection means further comprises a pair of annular ring pieces extending in the circumferential direction projectedly from the inner peripheral surface of the rim to the radial inner side and installed apart a specified distance from each other in the direction of the axle, a connection part circumferentially extending between the pair of ring pieces, having an axial clearance from the ring pieces, and installed on the radial outside of the disk, and damper members (6) formed of rubber elastic bodies through which the ring pieces are joined to the connection part. First engagement grooves extending in the circumferential direction are formed in the inside surfaces of the ring pieces facing each other, and second engagement grooves opposed to the first engagement grooves, forming pairs therewith, and extending in the circumferential direction are formed in both side faces of the connection part in the direction of the axle. The damper members are supported by the first engagement grooves and the second engagement grooves, and a clearance is formed between the outer peripheral surface of the connection part and the inner peripheral surface of the rim.
