Vehicle with turning mechanism has turning drive mechanism for exerting torque on one or other pair of wheels to turn body near centre of rotation axis of other pair of wheels

摘要

The four-wheel vehicle has a turning mechanism with a rotary bearing arrangement (24) for rotatably holding one pair (15,16) of front and rear pairs of wheels (11,12;15,16) on which no drive torque is exerted, a rotary position holding arrangement (32,40-46) for holding one pair of wheels in a given angular position along tangential directions to a curve, whereby the curve centre point is close to the centre point of the rotation axis of the other pair if wheels, and a turning drive mechanism (17,18) for exerting a torque on one or other pair of wheels to turn the body near the centre of the rotation axis (B) of the other pair of wheels.
