Abstract

A wheeled vehicle such as a wheel-chair has motor-driven wheels (1) and freely rotating swivel wheels (11, 11'). The motor-driven wheels (1) have shafts fixedly arranged in the vehicle and they are driven individually for steering the vehicle. In order to reduce those instabilities which can arise in the movement of the vehicle, one (11') of the freely rotating wheels is provided with a direction or steering control, so that it can be given a suitable angle in relation to the vehicle and to the movemenet direction thereof. For some movement states the angular direction control can be deactivated so that the freely rotating swivel wheel (11') can adjust itself freely in the usual way. For achieving the angular direction control of the swivel wheel (11') a chain or belt (21) runs about the swivel shaft (13') thereof and it also passes over a wheel (22). This wheel (22) is driven by an electric steering motor (19) through a not self-braking or not irreversible worm gear unit (23). The system steering control motor (19), reduction gear unit (23), chain or belt (21), is as seen as a unit, reversible, which allows a forced control of the angular position of the swivel wheel (11'), when the motor (19) is actively driven when feeding electric current thereto, and that the swivel wheel (11') can adjust itself freely to an arbitrary angular position when no current is fed to the motor (19).
