Patent number: 8381660Abstract: A track-guided vehicle wheel truck prevents wear and deterioration of a guide wheel and a guide rail, and ensures running stability while simplifying the structure. In the track-guided vehicle wheel truck, a guide frame 8 to which a guide wheel 9 guided by a guide rail 1 is mounted, can turn relative to a steering axle 6 of a running wheel 5. A support shaft 21 is provided on an axle bracket 20 provided in the steering axle 6 so as to be movable in the vehicle front and rear direction by straddling the steering axle 6. A link lever 22 capable of interlocking the turning of the guide frame 8 and the steering of the running wheel 5 is provided along the vehicle front and rear direction. A vehicle end-side end part of the link lever 22 is rotatably mounted to a connecting rod 19 that enables the steering of the running wheel 5. An intermediate part of the link lever 22 is rotatably mounted to the guide frame 8.Type: GrantFiled: July 1, 2009Date of Patent: February 26, 2013Assignee: Mitsubishi Heavy Industries Ltd.Inventors: Hiroki Kurahashi, Nobuyuki Fujio, Hiroyuki Kono, Yukihide Yanobu, Akihisa Kawauchi, Kousuke Katahira
