Railway propulsion system
Abstract
Abstract A PROPULSION SYSTEM FOR AN INDIVIDUAL CAR OF A RAILWAY TRANSPORTATION SYSTEM COMPRISES A ROTATING DRIVE TUBE EXTENDING LONGITUDINALLY OF AND RESILIENTLY SUPPORTED FROM THE CHASSIS OF THE CARI IN POSITION TO COOPERATE WITH REACTION WHEELS SPACED ALONG THE PATH OF THE CAR AT INTERVALS LESS THAN THE LENGTH OF THE DRIVE TUBE. THE DRIVE TUBE IS DRIVEN AT A GENERALLY CONSTANT SPEED SO THAT THE SPEED OF THE CAR PAST ANY REACTION WHEEL IS DETERMINED BY THE ANGULAR POSITION OF THE REACTION WHEEL RELATIVE TO THE DRIVE TUBE. SOME OF THE REACTION WHEELS ARE JOURNALLED IN PIVOTABLE MOUNTINGS TO BE RESPONSIVE TO EXTERNAL CONTROLS FOR VARYING THE SPEED OF THE CAR PAST THE WHEEL. AUXILIARY POWER MAY BE SUPPLIED DIRECTLY TO A REACTION WHEEL TO SUPPLEMENT THE POWER SUPPLIED THROUGH THE DRIVE TUBE. THE REACTION WHEELS MAY BE USED IN LATERALLY SPACED PAIRS TO CRADLE THE DRIVE TUBE AND THUS GUIDE THE CAR.
