  • Publication number: 20110239899
    Abstract: A low floor vehicle reduces, when the vehicle enters a curved track, the lateral force of the vehicle, prevents occurrence of vibration and creaking sounds of the vehicle, improves riding quality of passengers, and reduces wear of wheel flanges. A low floor vehicle includes a bogie frame 9 of a bogie 7, a pair of bogie frame cross beams 9a arranged along a vehicle lateral direction in the middle of a vehicle longitudinal direction of the bogie frame 9 and arranged spaced apart from each other in the vehicle longitudinal direction, and a pair of wheels 8 provided in each of a vehicle front edge direction and a vehicle rear edge direction with respect to the pair of bogie frame cross beams 9a of the bogie frame 9 and configured to travel on a track 1.

  • Publication number: 20110187317
    Abstract: Provided is a noncontact type power feeder system for feeding an electric power to a mobile object, which enables a quick charge and transmission of a high electric power and in which a power feeder and a power receiver can be readily manufactured at low cost, comprising a power feeder arranged along a running road surface for the mobile object 1, and a power receiver mounted to the mobile object, the power feeder and the power receiver being opposed fact-to-face to each other for feeding an electric power, wherein the power feeder is secured on the running road surface for the mobile object, or aerially above the running road surface while the power receiver is mounted at a position where the power receiver is opposed face-to-face to the power feeder with a predetermined gap therebetween when the mobile object is stopped at a position where the power feeder is set up, and each of the power feeder and the power receiver is composed of a planer core having long sides extended in the travel direction of the mob

  • Patent number: 7888912
    Abstract: Occurrence of overcharging and over discharging of batteries mounted on vehicles that travel on tracks in a wireless transit system is prevented by estimating a state of charge (SOC) of the batteries with accuracy. An equivalent circuit of the battery is composed of three circuit elements connected in series, including (i) a first component resistance R1 (ii) a component circuit which includes a capacitance C and a second component resistance R2 connected in parallel and (iii) an open circuit voltage of the battery. The open circuit voltage of the equivalent circuit is calculated using R1 calculated from measurements of current and voltage of the battery, as well as values k=R2/R1 and ?=C×R2. The SOC if the battery is calculated from the open circuit voltage.

  • Publication number: 20100258026
    Abstract: The object is to provide an obstacle-removing device for a removing obstacles on guideway, which is simple in configuration, low in manufacturing cost, and can remove the obstacles steadily and effectively, and of which the brushes for sweeping the running surface can be retracted easily when the device is in the rear side of traveling direction of the vehicle. The device comprises; a vertical frame positioned to the leading end in traveling direction of the vehicle, and a lifting/lowering device attached to the said vertical frame to lift and lower a brush holder attached to a vertically movable member which can be lifted and lowered by the lifting/lowering device, the brush holder having brushes for removing obstacles on the guideway; wherein the brush holder is pivotally attached to the vertically movable member such that the brush holder is tilting forward when the brushes held by the brush holder contact the running surface to perform obstacle-removing operation.
