TRANSVERSE DYNAMICS OF VEHICLE TYRES

DIE QUERDYNAMIK VON KRAFTFAHRZEUGREIFEN

The author deals with transverse forces in oblique motion and restitution moments in static and dynamic measurements, and the effects on the behaviour of the vehicle. The tyre equivalent model of V. Schlippe and Dietrich and a tyre equivalent model with mass effects are discussed in detail. The measurements and calculations shown allow the following conclusions to be drawn: the relation of transverse load and the angle of oblique motion is to a very great degree linear for modern tyres, so that the proportional relation of an equation for constant wheel load and static circular track is valid for the whole range of normal driving. The expression does not apply for transverse accelerations above about 0.5 g and tracks with low adhesion. In driving manoeuvres with excitations below about 1 c.p.s., such as induced by driver or wind disturbances, the tyre develops a running-in behaviour somewhat dependent on the road. Higher frequency excitations of the wheel rim oscillating angle, such as can arise in wheel kinetics by the combination of spring deflection and toe-in, result in inertia forces of the tyre on the vehicle. This influence can be taken care of by a certain equation. /TRRL/
