Electric wheel dump truck

Abstract

An electric wheel dump truck comprises a power system, a traveling system, a brake system, a hydraulic system, an electricity transmission system, a frame assembly, a truck front plate assembly, a driving cab assembly, a rearview mirror assembly, a brake resistance box, an electrical cabinet, an automatic lubrication system, an automatic arc extinguishing system, a ventilation system and a compartment system, wherein the frame assembly is arranged on the traveling system; the truck front plate assembly, the electrical cabinet, the driving cab assembly and the compartment assembly are all arranged on the frame assembly; and the tail part of the longitudinal beam of the frame assembly is articulated with a hinge support seat at the bottom of the compartment assembly. The electric wheel dump truck is compact in structure, and safe and reliable; each system assembly is rational in arrangement and low in production cost; and all the system assemblies are arranged in mass symmetrical distribution and low in center of gravity; and therefore, the stability of the truck in running can be improved.

Description

technical field [0001] The invention relates to a large electric wheel dump truck. Background technique [0002] The continuous development of China and the world economy has led to an increasing demand for coal and black and non-ferrous ores. According to the mining data of the world's major mining industries, large electric wheel dump trucks play an important role in mining, undertaking the mining and transportation of 50% of the world's coal and 80% of iron ore. At present, all kinds of large and medium-sized open-pit mines of 10 million tons or more in China, such as iron mines, coal mines, and copper mines, are being expanded on a large scale. direction development. Because the large-scale electric wheel dump truck integrates high-tech such as machine, electricity, hydraulic and computer, only a few countries such as the United States have the research and development capabilities in the world. The monopoly of the company, and a large number of imported complete vehic...

Problems solved by technology

Because the large-scale electric wheel dump truck integrates high-tech such as machine, electricity, hydraulic and computer, only a few countries such as the United States have the research and development capabilities in the world. The monopoly of the company, and a large number of imported complete vehicles have many problems: first, it affects China's energy security; second, the complete vehicles and spare parts are expensive and the delivery cycle is long, resulting in a substantial increase in mining costs; third, it seriously damages my country's electric wheel dump trucks Industry Survival and Development

[0003] In view of the low quality utilization coefficient of existing small-tonnage electric wheel dump trucks, the front axle and frame of large-tonnage electric wheel dump trucks with existing structures are often not able to bear a large force, the failure rate is high, and the service life cycle is difficult to guarantee. Therefore, it is necessary to improve the existing large electric dump trucks
