Abstract:
PCT No. PCT/SE91/00457 Sec. 371 Date Jan. 5, 1993 Sec. 102(e) Date Jan. 5, 1993 PCT Filed Jun. 25, 1991 PCT Pub. No. WO92/00858 PCT Pub. Date Jan. 23, 1992.A non-pneumatic supporting wheel includes a central part and a wheel-rim which is supported by the central part. The wheel-rim has an outer wheel-rim part which is intended to roll against an underlying surface, and an inner wheel-rim part which is located radially inwards of the outer wheel-rim part. At least the inner of the two wheel-rim parts is constructed from a plurality of curved, elongated elements which consist of a resilient material and which are spaced in the circumferential direction of the wheel. When seen in a section taken diametrically through the wheel, each of these elements presents parts which are curved in opposite directions. For the purpose of taking-up forces which act substantially radially between the wheel center and the region of the wheel in contact with the underlying surface when the wheel is subjected to load, the elements are elastically yielding in the radial direction of the wheel during increased bending of the elements. The circumferentially spaced and bendable elements are constructed so that both the sum of the bending of each small longitudinal section of the elements when the elements are subjected to load in the radial direction of the wheel and the sum of the product of the bending of each small section and the distance of this section from the underlying surface when the wheel is subjected to normal load is at least essentially zero.
