The invention provides a steering pump and a work vehicle. The steering pump comprises a stator, a rotor and an energy-saving device. At least part of the rotor is arranged in the stator. The energy-saving device is used for pushing the stator to be switched between the first position and the second position. When the stator is located at the first position, a steering pump stops oil suction and/or oil discharge, and when the stator is located at the second position, the steering pump conducts oil suction and/or oil discharge. The stator is pushed to the first position through the energy-saving device, oil suction and/or oil discharge of the steering pump are/is stopped, oil consumption of the steering pump in the parking or in-situ pumping state is reduced, and then the energy-saving effect is achieved.
本发明提供了一种转向泵和作业车辆。其中,转向泵包括定子、转子和节能装置。转子的至少部分设于定子中。节能装置用于推动定子在第一位置和第二位置之间切换。定子在第一位置时,转向泵停止吸油和/或排油,定子在第二位置时,转向泵进行吸油和/或排油。本发明通过节能装置推动定子至第一位置,实现转向泵停止吸油和/或排油,降低转向泵在驻车或原地打泵状态下的油耗,进而起到节能的作用。
