Kind Code:
A1
Abstract:
Provided is a guided wheel device for a guide track type vehicle, this guided wheel device being such that the structure is simple, that the cost can be reduced, that maintenance work can be easily performed, that the maintenance management cost can also be reduced, and that the wear adjustment position does not change due to vibrations during travel. More specifically, provided is a guided wheel device for a guide track type vehicle, this guided wheel device being equipped with a wheel axle (4) rotatably supported by a bearing (21), a main guided wheel (31) rotatably installed in the upper part of the wheel axle (4), and a branch guided wheel (32) rotatably installed in the lower part of the wheel axle (4). The rotation center (C1) of the main guided wheel (31) is eccentric with respect to the axle center (C2) of the wheel axle (4). The circumferential surface of the wheel axle (4) is provided with a plurality of piece-to-be-fitted receiving recesses (11 - 13) which are circumferentially disposed side by side. The bearing (21) is provided with a piece-to-be-fitted (25) which is to be fitted into the piece-to-be-fitted receiving recesses (11 - 13), and a fit adjustment device (26) which presses the piece-to-be-fitted (25) toward the wheel axle (4) in such a way that the piece-to-be-fitted (25) abuts one of the piece-to-be-fitted receiving recesses (11 - 13) and is capable of releasing the pressing force applied to the piece-to-be-fitted (25).
