Guide device for guide rail-type vehicle, and guide rail-type vehicle
Provided is a guide device for a guide rail-type vehicle which travels while being guided along a travel track. The guide device is provided with: guide wheels which include main guide wheels and branched guide wheels, the main and branched guide wheels being in contact with and roll on guide rails arranged on both sides of the travel track; steering arms which steer the vehicle; and elastic support members which each includes one end affixed to each of the steering arms and which each includes the other end including guide wheels rotatably supported thereon, the elastic support members absorbing an impact load by deflecting about the one end thereof.
1. A guide device for a guide rail-type vehicle traveling along a travel track while being guided along the travel track, the guide device comprising:
a plurality of guide wheels rolled by coming in contact with a plurality of guide rails, the plurality of guide rails including main guide rails and diverging guide rails, arranged on both sides of the travel track, each of the plurality of guide wheels including a main guide wheel and a turnout guide wheel, the main guide rails applying inward force to the main guide wheels toward an inner side of the guide rail-type vehicle, and the diverging guide rails applying outward force to the turnout guide wheels toward an outer side of the guide rail-type vehicle;
a plurality of steering arms to steer the vehicle being displaced upon receiving the inward force or the outward force; and
a flexible support member extending in a vehicle longitudinal direction, one end of the flexible support member being fixed to a tip end of each of the plurality of steering arms as a fixed end, and another end of the flexible support member rotatably supporting the main guide wheel and the turnout guide wheel, the flexible support member absorbing the inward force and the outward force by deflection of the flexible support member with respect to the fixed end serving as a supporting point, thereby suppressing an impact load transmitted to each steering arm.
2. The guide device for the guide rail-type vehicle according to claim 1 , wherein the flexible support member is a cantilever member.
3. The guide device for the guide rail-type vehicle according to claim 1 , further comprising a limiting member limiting a deflection amount of the flexible support member, the limiting member: (i) being attached to the tip end of each steering arm, (ii) extending along the flexible support member on both sides of the flexible support member in a vehicle width direction in non-contact with the flexible support member, and (iii) limiting the deflection amount of the flexible support member by abutment between the flexible support member and the limiting member.
4. A guide rail-type vehicle comprising:
a guide device for a guide rail-type vehicle traveling along a travel track while being guided along the travel track, the guide device including:
a plurality of guide wheels rolled by coming in contact with a plurality of guide rails, the plurality of guide rails including main guide rails and diverging guide rails, arranged on both sides of the travel track, each of the plurality of guide wheels including a main guide wheel and a turnout guide wheel, the main guide rails applying inward force to the main guide wheels toward an inner side of the guide rail-type vehicle, and the diverging guide rails applying outward force to the turnout guide wheels toward an outer side of the guide rail-type vehicle;
a plurality of steering arms to steer the vehicle being displaced upon receiving the inward force or the outward force; and
a flexible support member extending in a vehicle longitudinal direction, one end of the flexible support member being fixed to a tip end of each of the plurality of steering arms as a fixed end, and another end of the flexible support member rotatably supporting the main guide wheel and the turnout guide wheel, the flexible support member absorbing the inward force and the outward force by deflection of the flexible support member with respect to the fixed end serving as a supporting point, thereby suppressing an impact load transmitted to each steering arm.
