The invention relates to the technical field of coal car systems, in particular to an auxiliary driving system and an underground coal car. The auxiliary driving system comprises a closed pump set, a clutch and a variable displacement motor mechanism, the clutch is located between the closed pump set and a first speed reducer, and the clutch is used for connecting or interrupting power transmission between the first speed reducer and the closed pump set; the variable displacement motor mechanism is connected with the closed pump set and further connected with the second speed reducer, and the second speed reducer is used for being connected with wheels. After the closed pump set pumps hydraulic oil to the variable displacement motor mechanism, the variable displacement motor mechanism is used for driving the second speed reducer to rotate. The clutch is arranged between the closed pump set and the first speed reducer, so that the conventional closed pump set and the variable displacement motor mechanism can be assembled into the auxiliary driving system, and the problem that maintenance and replacement are limited due to the fact that the closed pump set and the variable displacement motor mechanism are specially made is solved; and the maintenance cost and the replacement cost of the auxiliary driving system are further reduced.

    本发明涉及运煤车系统技术领域,尤其涉及一种辅助驱动系统及井下运煤车。其中,该辅助驱动系统包括闭式泵组、离合器和变量马达机构,离合器位于闭式泵组和第一减速机之间,离合器用于连接或中断第一减速机与闭式泵组之间的动力传递;变量马达机构与闭式泵组连接,变量马达机构还与第二减速机连接,第二减速机用于与车轮连接;在闭式泵组向变量马达机构泵送液压油后,变量马达机构用于驱动第二减速机转动。本申请提供通过在闭式泵组和第一减速机之间设置离合器,即可使常规的闭式泵组和变量马达机构组装出辅助驱动系统,以降低闭式泵组和变量马达机构因特制而导致的维修更换均受限制的问题,进而降低辅助驱动系统的维护成本和更换成本。
