摘要 A vehicle has a compartment joined to a carrier by springs. An attracting magnetic device has a first part (e.g. a ferromagnetic travelling field stator) mounted on a roadway, and a second part (e.g. spaced permanent magnets forming a synchronous linear motor in combination with the stator) mounted on the carrier. The two parts of the magnet device lie opposite one another to leave an air gap therebetween and so to hold the vehicle in spaced relation to the roadway. An additional-force device is mounted to act between the vehicle and the roadway and supplements the force of the magnetic attraction to make up the holding force needed to maintain the vehicle in the desired position relative to the roadway. The part of the magnetic device that is mounted on the vehicle can be displaced relative to the additional-force device to vary the width of the air gap and thereby vary the force of the magnetic attraction. Such displacement can be caused by a device responsive to variations in distance between the vehicle compartment and the carrier on compression or expansion of the springs.
