The invention discloses a cooling fan driving device of a two-section crawler, relates to the technology of engineering machinery, in particular to improvement of the cooling fan driving technology ofthe two-section crawler. The cooling fan driving device comprises a fan bracket, a belt, a driving pulley, a driven pulley, a fan clutch and a cooling fan, the driving belt pulley connected with theoutput end of the crawler engine is mounted at the lower part of the fan bracket mounted between the crawler engine and the radiator assembly; the cooling fan is arranged above the fan bracket; the fan clutch on a main shaft of the cooling fan is connected with the driven belt pulley; the belt is connected between the driving pulley and the driven pulley. The problems that the cooling fan of the crawler is arranged in an engine direct connection type driving mode, the installation space position is limited, and the transmission efficiency is low due to the fact that a hydraulic pump-motor typedriving mode is adopted are solved.

    一种双节履带车的冷却风扇驱动装置,涉及工程机械技术,具体涉及用于双节履带车的冷却风扇驱动技术的改进。包括风扇支架、皮带、主动皮带轮、从动皮带轮、风扇离合器和冷却风扇;安装于履带车发动机与散热器总成之间的风扇支架的下部安装有与履带车发动机输出端联接的主动皮带轮;冷却风扇设置于风扇支架上方,冷却风扇主轴上的风扇离合器联接从动皮带轮;主动皮带轮和从动皮带轮之间连接皮带。解决了履带车的冷却风扇采用发动机直连式驱动方式布置,安装空间位置受限,以及采用液压泵‑马达式驱动传动效率较低的问题。
