Gear 4 and Rack 7-3 are used for running on the vertical rail section.
Not only do these gears and racks need to be used, but they also have problems at the beginning of their mutual meshing, resulting in teeth being chipped. Sometimes a large propulsion force is required and a speed reducer is installed to obtain this.However, when running on horizontal rails, the propulsive force may be smaller than when running on vertical rails, but on the other hand, high speeds are required. Restricted by the speed reducer, sufficient travel speed cannot be obtained.

とができる。"Effects of the Invention" As explained above, according to the present invention, in a track-type electric bogie that runs on a track rail having a horizontal rail and a vertical rail, the drive wheels for running the horizontal rail and the vertical rail have different drive propulsive forces. In addition to providing drive wheels for running on the rails, at least a pressing mechanism for pressing the drive wheels for running on the vertical rails against the vertical rail is provided to apply a contact friction force necessary for vertical running between these rails and the drive wheels. Therefore, it is possible to obtain a cart that can sufficiently run not only on the horizontal rail section but also on the vertical rail section with a simple structure without requiring gears and racks as in the conventional method, and since it does not have gears and racks. This eliminates the troubles that occur when a problem initially occurs in the meshing of gears and racks, and the diameters of each of the drive wheels are made different, with the smaller diameter drive wheels being used for running on vertical rails and the larger diameter drive wheels being used for running on horizontal rails. By using it for running, or by differentiating the reduction ratios of the reducers for giving rotational force to both drive wheels, high speeds can be achieved when running on horizontal rail sections where each drive wheel requires small torque. , high propulsion force can be obtained when traveling on the vertical rail section.
