Title: Method for improving steering performance stability by using mass non-uniformity of tire/wheel
Inventor: KUNSCH ROMAIN
IPC: G01M1/30
Filed: 2002-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for improving the steering performance and the steering performance stability of a vehicle. SOLUTION: The force in the radial direction and/or the tangential force of the adjusted quantity is fluctuated in one or two or more tire/wheel assembly by the mass non-uniformity, the dimension non-uniformity and/or the rigidity non-uniformity while minimizing the fluctuation in the transverse force (for example, couple imbalance). In the case of the mass non-uniformity, the excessive mass of the adjusted quantity is preferably added to the tire, in particular, a tread area, for example, a sector of a tire element having a heavy splice, an excessive cloth piece, or an excessive mass. The excessive mass is symmetric with respect to the meridian in order to generate not the couple imbalance but the static imbalance, and the residual static imbalance(RSI) is giving to the tire thereby.
