Abstract
This invention relates to tire testing apparatus and, more particularly, to an improved roadwheel for use with tire testing apparatus of various types which are capable of more accurately measuring the roadability and wear characteristics at high speeds of rotation. The roadwheel has angularly-inclined web plates connecting its hub and rim portions to provide greater stability and durability at greater stresses caused by increased centrifugal forces. The wheel also provides greater margins of safety in tire testing operations.
Claims4
An improved roadwheel for testing tires at high speed comprising a rotatable wheel having a circular outer rim portion, said rim portion being formed with a spaced pair of annular stepped portions;
- a hub portion for supporting said wheel on a frame, said hub portion being formed with a spaced pair of annular stepped portions;
- means for driving said wheel from low to high speeds of rotation, said wheel having a pair of similar annular web plate members joining said hub portion to said outer rim portion, said web plates being joined to the hub and outer rim portions at the annular stepped portions thereof, in a symmetrical uniform convex arrangement by welds;
- a plurality of reinforcing members extending between and interconnecting the web plates;
- and the outer rim portion having tapered thickness outer ends extending beyond the web plates.
