PCT No. PCT/JP82/00347 Sec. 371 Date Jan. 7, 1983 Sec. 102(e) Date Jan. 7, 1983 PCT Filed Aug. 30, 1982 PCT Pub. No. WO84/00932 PCT Pub. Date Mar. 15, 1984.One of several inventions claimed is a method of providing increased traction to the driving wheels of a high speed transportation vehicle. The vehicle is placed within a tubular passageway, equipped with wheels arranged to contact the tube at three or more equidistant contact points, and these wheels are pressed against the inside surface of the tube by means of controlled application of powerful hydraulic pressure. Vertical stability of the vehicle is achieved by a new apparatus comprised of a spoke attached to the vehicle which projects outward to a point adjacent to but not touching the tube, a set of wheels transversely mounted on each side of the spoke, and a pair of L-shaped guide rails between which the wheels roll. An improved wind resisting braking system is claimed which uses extendable baffle plates and air ports from which compressed air is ejected in a direction opposed to the direction of travel. |
