Mining driving force self adoption multi-gear automatic speed changing double-motor steering drive axle

Abstract

The invention belongs to the technical field of coal mine downhole railless auxiliary transportation equipment design and manufacturing and particularly provides a mining driving force self adoption multi-gear automatic speed changing double-motor steering drive axle. By adoption of the mining driving force self adoption multi-gear automatic speed changing double-motor steering drive axle, the problem that a mining electric drive vehicle cannot efficiently meet the demands of coal mine downhole complex and variable working conditions is solved. The steering drive axle comprises a water cooled middle double-drive anti-explosion motor, a first planetary reducing mechanism, a second planetary reducing mechanism, a differential mechanism, an axle shaft, an axle shell and an electronic control unit. The mining driving force self adoption multi-gear automatic speed changing double-motor steering drive axle simultaneously has the functions of driving, steering, automatic speed changing, active safety, travelling braking and parking braking, and mechanical control gear shifting devices, clutches, transmissions, transmission shafts, mechanical differential mechanisms and the like needed by traditional vehicles are omitted, so that a drive system and a whole vehicle are simple in structure and short in transmission chain, and transmission efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of design and manufacture of trackless auxiliary transportation equipment in coal mines, in particular to a mine driving force self-adaptive multi-speed automatic transmission double-motor steering drive axle. Background technique [0002] With the popularization and use of explosion-proof diesel engine-powered rubber-tyred vehicles, trackless rubber-tyred vehicles powered by diesel engines have exhaust pollution and noise pollution, which further causes the deterioration of the working environment in coal mines and affects the health of underground workers. It is a great hazard, and also buried a certain degree of hidden safety hazards, as well as insufficient power in an oxygen-sparse environment, which has become a bottleneck for the development of trackless auxiliary transportation and a weak link that restricts the development of coal production in my country. Pure electric explosion-proof rubber-tyred vehicl...
