ABSTRACT:
Linear motor supporting apparatus are mounted upon the front and rear portions of each bogie of a vehicle so as to maintain the predetermined distance defined between an on-board coil and a ground stator, the on-board coil and the ground stator together constituting the linear-induction motor. The linear motor supporting apparatus incorporates a servo device which regulates the vertical position of the on-board coil in accordance with the contour of the ground stator so as to maintain the on-board-coil-to-ground-stator distance at the predetermined value. The servo device consists of a valve body, a valve box, and a servo device body. The valve body is secured to a sensor member, which runs upon and is maintained in contact with the ground stator. The valve box is secured to the on-board coil. The servo device body is mounted through means of a spring to the bogie. The ground stator may have some laying errors and there may be variations in its height. When the sensor member during operation of the vehicle is elevated due to height variations of the ground stator, the valve body move upwardly causing, through means of hydraulic pressure, the valve box to follow its upward motion. This in turn causes the on-board coil, which is integral with the valve box, to move upwardly thus maintaining the distance defined between the on-board coil and the ground stator constant.
