Abstract
Provided is a method of fitting a tire-and-wheel assembled body to an axle, which is capable of resolving imbalance in a state of fitting an assembled body including a tire and a wheel to an axle. In this fitting method, a tire is fitted to a wheel, and then core positions of fastening holes are, or a core position of a hub hole is, adjusted in the wheel to minimize an amount of eccentricity of an assembled body including the tire and the wheel.
Claims8
A method of fitting a tire-and-wheel to assembled body to an axle to form an assembled body so that an amount of eccentricity of the assembled body can be minimized, the method comprising the steps of:
- fitting a tire to a wheel to form the tire-and-wheel assembly body;
- measuring runout of the assembled body around a standard rotational axis of the wheel to establish a peak position of the runout;
- determining normal core positions of first fastening holes around the rotational axis of the wheel, the normal core positions being disposed at a predetermined radius from the rotational axis with sequential ones of the normal core positions being angularly disposed apart equidistantly from one another at a predetermined angle;
- forming second fastening holes with associated second core positions into the wheel, the second core positions being displaced relative to respective ones of the normal core positions in a same direction as the direction of the peak position runout;
- and
- mounting the tire-and-wheel assembly body to the axle.

- determining a normal core position of a first hub hole around the rotational axis of the wheel, the normal core position coinciding with the rotational axis of the wheel;
- forming a second hub hole with a second core position into the wheel, the second core position being displaced relative to the normal core position in a same direction as the direction of the peak position runout;
- and
- mounting the tire-and-wheel assembly body to the axle.
