In design, a sealing ring 1-1 is sleeved at the end part of a first quick coupling 2-1, the first quick coupling 2-1 is clamped on a metal pipe 3-1, and the metal pipe 3-1 is connected with a rubber hose 5-1 through a steel joint 4-1 in a buckling manner. The sealing ring 1-1 is formed by injection molding of EPDM, the first quick connector 2-1 is formed by injection molding of PA66+ G35 materials, the metal pipe 3-1 is formed by bending and forming of a double-layer reel pipe TDW-Z25-F4.76, the steel connector 4-1 is formed by stamping of ML08AL, and the rubber hose is formed by thermoforming of EPDM with a woven layer. The arrangement is that the rubber hose is connected between the two metal pipes 3-1, which is equivalent to the arrangement between the power assembly and the vehicle body longitudinal beam on the whole vehicle, because the vibration of the power assembly relative to the vehicle body longitudinal beam is compensated through the length and the elastic deformation of the rubber hose. However, the expansion rate of the rubber hose is large, so that the hydraulic stroke transmission efficiency is low, and is usually about 80%.
