Document Type and Number:
WIPO Patent Application WO/2010/095286
Kind Code:
A1
Abstract:
A low-floor vehicle improved in the riding comfortableness of the occupants and reduced in the wear of wheel flanges by reducing the lateral pressure of the vehicle to prevent the vibration and creaking noise of the vehicle from occurring when the vehicle runs on a curved track. The low-floor vehicle comprises journal members (10) each of which connects a pair of wheels (8) to each other and is attached to a truck frame (9) and a truck frame lateral beam (9a) laterally disposed nearer the center of the truck frame (9) than the journal member (10). The journal members (10) are capable of revolving relative to the truck frame (9). A connection member (12) connects the journal member (10) and the truck frame lateral beam (9a). The connection member (12) is attached to the lateral center of the truck frame lateral beam (9a) rotatably about the axis extending in the height direction of the vehicle.
