Abstract
Abstract An independent wheel suspension for steerable wheels has a wheel bearer connected to the vehicle body and first and second guide wheel members. The first guide wheel member comprises separate guide links coupled at articulated points to the vehicle body and to the wheel bearer, and a coupler connected between the articulated points at the wheel bearer. The coupler transverses a bisector of an angle formed by the guide links and is angled rearwardly and inwardly from the wheel. This wheel suspension enables the castor distance to be increased at the wheel in a curve during wheel turning, while maintaining a specified basic arrangement for the guide links.
