Abstract
1444726 Vehicle wheels DUNLOP Ltd 28 Nov 1973 [15 Dec 1972] 58156/72 Heading B7C A wheel rim is characterised by its crosssectional profile and comprises an outboard rim part 1 detachably secured to an inboard rim part 2. The outboard rim part 1 has a crosssectional profile which comprises: a bead retaining flange 12 providing a support surface for the sidewall of a deflated tyre; a curved bead-heel seating portion ST; a straight portion TU inclined at 5 degrees to the rotational axis of the wheel rim; and a curved bead-toe seating portion UV with a radially outer surface having a radius of curvature of between 5 and 9 mm., the bead-toe seating portion UV terminating at a plane CC spaced at a distance between 18 and 20 mm. from the plane AA of the flange 12. The inboard rim part 2 has a cross-sectional profile which comprises: a curved portion WX which is substantially a mirror image of the portion UV; a base portion XY extending parallel to the rotational axis of the wheel rim and having an external diameter of between 2 and 3 mm. less than the nominal diameter of the wheel rim (measured between lines such as the line D-D in Fig. 1); a straight portion YZ inclined at an angle of 5 degrees to the rotational axis of the wheel rim; and a curved bead-heel seating portion J and a bead retaining flange 13 which are substantially mirror images of the corresponding portion and flange of the outboard rim part. The wheel rim is intended for use with a tyre having beads 5, 6 with extended toe portions 9, 10. The wheel rim may be provided with a support element for spacing the tyre beads and for supporting the crown region of a deflated tyre. Such a support element may take the form of an annular plastics member fitted around the base of the wheel rim, or an annular plate fitted between the inboard and outboard rim parts.
