摘 要
電機(jī)車是軌道車輛運(yùn)輸?shù)囊环N牽引設(shè)備，動(dòng)力是利用牽引電機(jī)驅(qū)動(dòng)車輪轉(zhuǎn)動(dòng)，借助車輪與軌面間的摩擦力，使機(jī)車在軌道上運(yùn)行。機(jī)車運(yùn)輸能行駛的坡度有限制，運(yùn)輸軌道坡度一般為3‰，局部坡度不能超過30‰。蓄電池電機(jī)車是現(xiàn)代地下工程，包括鐵路、公路、地鐵、礦山、隧道等施工的重要運(yùn)輸牽引設(shè)備之一。礦用電機(jī)車主要用于井下運(yùn)輸大巷和地面的長距離運(yùn)輸。它相當(dāng)于鐵路運(yùn)輸中的電機(jī)車頭，牽引著由礦車或人車組成的列車在軌道上行走，完成對煤炭、矸石、材料、設(shè)備、人員的運(yùn)送。國內(nèi)電機(jī)車主要采用直流傳動(dòng)方式。蓄電池式電機(jī)車是用蓄電池供給電能的。蓄電池充電一般在井下電機(jī)車庫運(yùn)行。

ABSTRACT
Motor vehicle is a kind of traction equipment for rail vehicles. It is driven by traction motor and the wheel rotates with the friction between the wheel and rail. Locomotive transportation can travel the slope limit, transportation rail slope is generally 3 per thousand, local slope should not exceed 30 per thousand. Battery motor vehicle is a modern underground engineering, including railway, highway, subway, mine, tunnel and other important transport traction equipment.The main use of the coal mining motor is the long-distance transportation of the underground transportation roadway and the ground.. It quite in railway transportation of motor front, pulling consisting of car or car of the train to walk on the track, complete the transportation of coal, coal gangue, material, equipment, personnel.The main motor car of the domestic adopt transmission mode. Battery motor vehicle is supplied with batteries. Battery charging often in the underground motor garage.
