Spoke angle adjustment method of the steering wheel

摘要

PPROBLEM TO BE SOLVED: To provide a spoke angle adjusting method of a steering wheel capable of certainly reducing the burden on a worker without a large-scale facility, and efficiently and accurately adjusting a spoke angle. PSOLUTION: While a vehicle is placed on a testing machine on a bench and in a virtual traveling state, a steering wheel is operated to successively measure at least two turned angles, and lateral force on a front wheel side and lateral force on a rear wheel side in each turned angle are simultaneously measured. From the measured result, each relational expression indicating lateral force change on the front wheel side and lateral force change on the rear wheel side to the turned angle change of the steering wheel is obtained. A spoke angle when a vehicle is in a straight-ahead traveling state is calculated from each relational expression. Toe angle adjusting amount is obtained from the calculated spoke angle, and the toe angle is adjusted by the adjusting amount. PCOPYRIGHT: (C)2008,JPO&INPIT
