Zusammenfassung:	The utility model discloses a double-hydraulic-pump power take-off mechanism of a pure electric off-highway mining dump truck, which comprises a power take-off motor and two hydraulic pumps, and the two hydraulic pumps are respectively connected to two ends of the power take-off motor. A rotating shaft of the hydraulic pump is rigidly connected with a rotating shaft of the power take-off motor; one of the two hydraulic pumps is a steering pump, and the other hydraulic pump is a lifting and disc braking double pump. The hydraulic power takeoff device solves the technical problem that power takeoff is carried out on two high-power hydraulic pumps at the same time in a narrow space. 本实用新型公开了一种纯电动非公路矿用自卸车双液压泵取力机构，包括：取力电机和两个液压泵，两个液压泵分别连接在取力电机两端；液压泵的转轴与取力电机的转轴刚性连接；两个液压泵中一个为转向泵，另一个为举升和盘制动双联泵。本实用新型解决了狭小空间下同时给两个大功率液压泵取力的技术难题。
