TRAVELING SYSTEM FOR A DRIVING VEHICLE
First Claim
1. A traveling system comprising:
- a driving vehicle that is driven by a driving unit;
a driving motor mounted on the driving vehicle; and
a plurality of power supply sections provided at predetermined locations spaced apart with each other on a traveling path of the driving vehicle;
wherein;
(i) each of the power supply sections is detachably connectable with the driving vehicle to move together with the driving vehicle and supply power to the driving motor of the driving vehicle, (ii) all of the power supply sections are disconnected from the driving vehicle when the driving vehicle runs with a low load, such that power is not supplied to the driving motor, and (iii) one of the power supply sections is connected to the driving vehicle when the driving vehicle runs with a high load, so as to supply power to the driving motor; and
wherein the driving unit comprises a driving engine for driving at least one rear wheel of the driving vehicle, the driving motor is independent of the driving unit, and the driving motor drives at least one front wheel of the driving vehicle.

Abstract
An assistance vehicle is connected to a dump truck on or at bases of ascending paths and power is supplied as auxiliary power from the assistant vehicle A to a driving motor in the dump truck. Because of this features a driving unit of the dump truck (a generator for supplying power to the driving motor in the dump truck or a generating engine for driving the generator) is required only to have the performance sufficient for running on horizontal paths, which enables size reduction of the driving unit and as a result cost reduction of the dump truck. Further the assistant vehicle is connected to the dump truck and moves together with the dump truck, so that a freedom degree of the dump truck for a traveling path can substantially be improved.

5. A traveling assisting method for a driving vehicle traveling on a traveling path, wherein the driving vehicle includes a driving unit and a driving motor, the method comprising:
-
providing a plurality of electric power supplies including a first electric power supply and a second electric power supply respectively at a first point and a second point spaced apart from the first point on the traveling path of the driving vehicle, each of the electric power supplies being connectable with the driving vehicle to move together with the driving vehicle and supply power to the driving motor of the driving vehicle and detachable from the driving vehicle;
attaching the first electric power supply to the driving vehicle to assist the traveling of the driving vehicle, when the driving vehicle reaches the first point on the traveling path;
detaching the first electric power supply from the driving vehicle one of;
(i) between the first point and the second point on the traveling path, and (ii) at the second point on the traveling path; and
attaching the second electric power supply to the driving vehicle to assist the traveling of the driving vehicle, when the driving vehicle reaches the second point on the traveling path. - View Dependent Claims (6)
