Patent ID: 8776696

Claim:
A low floor vehicle, comprising: a truck arranged under a vehicle body; a truck frame configured as a frame member of the truck; a pair of wheels being pivotable independently from each other around a same axis which extends in a vehicle width direction, and the wheels configured to travel on a track; a journal member coupling the pair of wheels and attached to the truck frame; a truck frame lateral beam arranged along the vehicle width direction at a position closer to a center in a vehicle longitudinal direction of the truck frame than the journal member; and a pair of truck frame longitudinal beams extending in the vehicle longitudinal direction at a position close to a center in the vehicle width direction of the pair of wheels, and being disposed spaced apart from each other in the vehicle width direction; wherein the pair of wheels, the journal member, and the truck frame lateral beam are provided at each of a position close to a vehicle front and a position close to a vehicle rear in the truck; wherein the journal member is configured to turn with respect to the truck frame; wherein a coupling member couples the journal member and the truck frame lateral beam; wherein the coupling member is attached to a center in the vehicle width direction of the truck frame lateral beam to be pivotable around an axis extending in a vehicle height direction; wherein a restoring rod or a horizontal damper is arranged along the vehicle longitudinal direction in the truck and configured to be retractable in the vehicle longitudinal direction, one end of the restoring rod or the horizontal damper is attached to the journal member, and the other end of the restoring rod or the horizontal damper is attached to the truck frame lateral beam; wherein an actuator is arranged on at least one of left and right exteriors in the vehicle width direction of the coupling member and is reciprocatingly moveable in the vehicle longitudinal direction, one end of the actuator is attached to the journal member, the other end of the actuator is attached to the truck frame lateral beam, and operations of the actuator are controlled so as to correspond to a linear traveling state of the vehicle and a curved traveling state of the vehicle, whereby the journal member is configured to turn with respect to the truck frame; and wherein two stopper members are provided in the truck frame, one of the stopper members is arranged at a position between the coupling member and the restricting rod or the horizontal damper and the other of the stopper members is arranged at a position between the coupling member and the actuator such that the stopper members are configured to come into contact with the coupling member to regulate pivotal movement of the coupling member.
