Mining timeliness four-wheel drive automatic speed changing multi-mode power driving system

Abstract

The invention belongs to the technical field of design and manufacture of coal mine down hole railless auxiliary transportation equipment, and particularly to a mining timeliness four-wheel drive automatic speed changing multi-mode power driving system. The problem that a mining electric driving vehicle cannot effectively meet the requirement of complicated changing conditions of the coal mine down hole is solved. The power-driven system comprises a water-cooled type middle dual-drive anti-explosion motor, a planetary speed reducing mechanism I, a planetary speed reducing mechanism II, a left output flange and a right output flange, and the dual-drive anti-explosion motor is connected with the planetary speed reducing mechanism I, the planetary speed reducing mechanism II, the left output flange and the right output flange correspondingly through left rotating shafts and right rotating shafts which penetrate through a center. The mining timeliness four-wheel drive automatic speed changing multi-mode power-driven system has obvious advantages that two-motor drive, automatic transmission and driving force switching in the driving system are integrated together, drive mode, driving force switching and automatic speed charging are integrated together, the structure is compact, and making the coal mine vehicle realize the vehicle multiple driving force output and front wheel drive, rear wheel drive and four-wheel drive of the vehicle of the coal mine vehicle can achieve real-time switching to ensure that the motor can work in the efficient range in a long time, the energy use ratio and the applicability of a variety of mine conditions are improved, the drive mode, driving force switching, and automatic speed charging are integrated together, and the driving system is accorded with the using conditions and the development direction of the vehicle of coal mine down hole.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of underground trackless auxiliary transportation equipment in coal mines, in particular to a mine-used timely four-wheel drive automatic variable-speed multi-mode power drive system. Background technique [0002] With the popularization and use of rubber-tyred vehicles powered by explosion-proof diesel engines, the rubber-tyred vehicles powered by diesel engines have exhaust pollution and noise pollution, which has caused further deterioration of the working environment in coal mines and has caused great harm to the health of underground workers. At the same time, it has buried a certain degree of safety hazards, and the lack of power in an oxygen-thin environment has become a bottleneck for the development of trackless auxiliary transportation and a weak link that restricts the development of my country's coal production. [0003] At present, many domestic manufacturers and researc...
