Abstract

1294554 Vehicle wheels FICHTEL & SACHS AG 30 July 1970 [13 Aug 1969] 36927/70 Heading B7C A vehicle wheel comprises a rim 7, a hub which itself comprises an axle and a sleeve 2 mounted thereon and two sets of radially extending connection units, e.g. spokes 6 which connect the rim and hub. The radially inner parts of the connection units are separate from one another and spaced in the direction of the axis of the hub unit and the radially inner parts of each set are provided with an annular connecting member, e.g. flanges 4, 5, for attachment to the hub unit. Means, e.g. profiled flanges 8, are provided to hold the hub sleeve 2 in an engaged position between the flanges 4, 5 by engaging means, e.g. teeth 9. One of the annular connecting members and the hub sleeve 2 are provided with positioning means, e.g. the profiled flanges 8, whereby the disengaged hub member can be passed through the centre of the one annular connecting member to be positioned between these members for engagement therebetween. The above connection secures the hub sleeve 2 against rotation relative to the flanges 4, 5, whilst axial displacement of the hub is prevented by the tension of the spokes 6. Recesses 12, Fig. 3, corresponding in number and complementary in shape to the teeth 9 are provided on the flanges 4, 5 on their edges which are adjacent to the hub sleeve 2, so that sleeve 2 with flanges 8 and teeth 9 can be pushed through the flanges 4, 5. The spokes 6 may be welded or hard-soldered to their associated flanges 4, 5 respectively. In a further embodiment, Fig. 5, an annular flange 54 has a thickened portion 55 on its radially outer edge in which screw-threaded bores 57 ase formed so as to receive the screw-threaded hub ends of spokes 56. The spokes may also be provided with bent-over ends for securing them to bores formed in the annular flanges. Alternatively, the annular flanges may be provided with radially extending corrugations which receive the ends of the spokes. An annular flange 84, Fig. 8, is composed of annular discs 80, 81 between which are received spokes 86. In this embodiment, teeth 89 are arranged on the flange 84 and co-operate with corresponding recesses on the profiled flanges of the hub sleeve.
