Problems solved by technology
[0002] At present, the application of hydraulic power units in traditional automobiles is powered by engines. The gasoline or diesel consumed by them not only consumes non-renewable petroleum energy in nature, but also causes serious air pollution.
The working speed of the actuator in the hydraulic power unit is achieved by changing the engine rotation speed to change the flow of high-pressure oil in the hydraulic system, and the engine cannot stop working after the actuator is completed, so that the engine and hydraulic power unit are always in working condition , wastes energy, and reduces component life

The invention provides a hydraulic power system and application thereof in new energy vehicles. The hydraulic power system comprises a hydraulic power actuator and a hydraulic power controller. The hydraulic power actuator comprises a motor, a hydraulic gear pump and a first hydraulic cylinder. The motor drives the hydraulic gear pump and drives the first hydraulic cylinder to work. The hydraulic power controller comprises a hydraulic pressure switch. The hydraulic pressure switch detects inner oil pressure of the hydraulic power actuator and powers off the motor when the oil pressure reaches a preset threshold. The motor drives the hydraulic gear pump so as to drive the hydraulic cylinder to work, so that a power battery is used a power source for the hydraulic power system and application of the hydraulic power system in the new energy vehicles is achieved. In addition, when the hydraulic power actuator actuates to a certain position, the motor is stopped, so that energy utilization rate is increased.
Description
technical field [0001] The invention relates to the field of hydraulic systems, in particular to a hydraulic power system and its application in new energy vehicles. Background technique [0002] At present, the application of hydraulic power units in traditional automobiles is powered by engines. The gasoline or diesel consumed by them not only consumes non-renewable petroleum energy in nature, but also causes serious pollution to the air. The working speed of the actuator in the hydraulic power unit is achieved by changing the engine rotation speed to change the flow rate of high-pressure oil in the hydraulic system, and the engine cannot stop working after the actuator is finished, so that the engine and the hydraulic power unit are always in working condition , wasting energy, and reducing the service life of components. [0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Contents of the invention [0004] One of the o...
