Definitions
- An object of the invention is to provide a PAVT wheel which overcomes these problems, is easy and quick to adjust and which has good lateral, i.e. in directions parallel to the rotary axis of the wheel, and radial truth.
- the disc is of uniform thickness and in elevation has the shape of an irregular octagon formed by taking a square and cutting off the corners so that the disc has four longer sides 12 and four shorter sides 13, the sides 12 and 13 being arranged alternately around the periphery of the disc.
- the sides 13 are arcuate.
- the disc has a central hole 14 to receive a vehicle hub and a ring of bolt holes 15 whereby it can be connected to the hub.
- the disc has a central or nave portion 11 , an inner portion 11 b substantially perpendicular to the rotary axis of the wheel, a conical portion 11 and an outer portion 11 d which is also perpendicular to said rotary axis.
