Hydraulic valve assembly, hydraulic system and vehicle

The invention relates to the technical field of vehicles. The embodiment of the invention provides a hydraulic valve assembly, a hydraulic system and a vehicle. According to the hydraulic valve assembly, the hydraulic system and the vehicle, the hydraulic valve assembly at least comprises the valve body, the hydraulic pipeline and the control valve assembly, the hydraulic pipeline is integrated in the valve body, the valve body is provided with the corresponding oil port, and therefore the hydro-pneumatic spring can be conveniently connected to the corresponding position of the hydraulic pipeline through the corresponding oil port; and then the control valve assembly is used for controlling connection and disconnection between the hydraulic pipeline and the corresponding oil port so as to control the action of the corresponding hydro-pneumatic spring. Therefore, the complexity of pipeline connection is reduced, and the problems of pressure loss, low efficiency and difficulty in assembly and maintenance of a h
