Problems solved by technology

[0005] However, in the technology described in the above-mentioned gazette, since the equipment for supplying electric power to the dump truck from the outside uses the overhead power line equipment installed on the ground, the dump truck can only be installed on the driving road where this equipment is installed. can only be able to drive, there is a problem that the driving range is very limited
In addition, when extending the uphill road, it is necessary to install overhead wire equipment, and the corresponding scale becomes larger, which requires construction and cost.

Embodiment Construction

[0023] Hereinafter, an embodiment of the present invention will be described based on the drawings.

[0024] figure 1 It is a schematic diagram showing a state in which a dump truck (self-propelled vehicle) D is driven on an uphill road using a traveling system according to an embodiment of the present invention. figure 2 It is a schematic diagram showing a state in which the dump truck D is driven on a downhill road using this traveling system. In addition, in this embodiment, at figure 1 The body of the dump truck D shown on the uphill road is empty, in that figure 2 The body of the dump truck D shown on the downhill road is fully loaded with goods, but it is not limited thereto, and the opposite situation is also possible.

[0025] This traveling system is roughly as follows.

[0026] That is, when the dump truck D travels on an uphill road, when traveling under a high load that imposes a large load on the self-propelled device, the dump truck D is connected to a mope...

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.

Description

technical field [0001] The invention relates to a driving system of a self-propelled vehicle. Background technique [0002] For example, a large dump truck with a load capacity of 100 tons has a self-propelled engine or a self-propelled electric motor as a self-propelled device. In a type having a self-propelled engine, power output from the self-propelled engine is transmitted to wheels through a transmission. In the type having an electric motor for self-use, a generator is driven by an engine for power generation, the electric motor for self-use is driven by electric power generated by the generator, and wheels are driven by the output power of the electric motor for self-use. Such dump trucks are often used in mine development, etc., but self-propelled devices consisting of self-propelled engines, generators, etc. are very large in size because they need to travel reliably on uphill roads in mines. [0003] However, when the dump truck travels on a downhill road or a f...
