Looks dangerous, I would not try it for my car.

Hydraulic mounting

Rubber damping is very difficult to produce. In order to improve the excessive vibration such as impact, the mounting must have a great damping force, which requires hydraulic mounting, which can also reduce the mounting stiffness at high frequencies and improve the effect of vibration and noise reduction. (Thanks for the help and support of Chongqing Feilong Jiangli Auto Parts technical department)

1) Hydraulic suspension structure inertia channel - decoupled disc hydraulic suspension structure see the following figure, with a central bolt to a common tapered rubber suspension pad (rubber main spring) fixed at the top, together with the diaphragm to form an upper cavity. The lower chamber consists of an elastic beryllium skin film and a diaphragm, the wrinkle skin film is protected by a fixed cover, and the fixed cover and the wrinkle skin film form an air chamber connected with the atmosphere. The baffle plate has circular or spiral channels, and the damping buffer can flow through the upper cavity through the upper cavity to the lower cavity.

2) The working principle of the hydraulic suspension is that when the suspension is excited by low and large amplitude (150Hz, 1-2mm) at the end of A, the displacement amplitude of the decoupling disc is larger, reaching the upper and lower limit positions. The liquid mainly flows through the inertial passage between the upper and lower cavities, so that the whole suspension stiffness increases and plays the role of damping and vibration attenuation. When the excitation displacement is high frequency and small amplitude (50-200Hz, 0.050.2m), the dynamic response of the liquid in the inertial passage tends to attenuate gradually, and the flow tends to cut off, mainly because the decoupling disc moves in its free stroke, so that a small mounting stiffness can be obtained to reduce the vibration. In the design of hydraulic mount, arbitrary dynamic elastic characteristics can be achieved by changing dynamic parameters, aperture and length of inertial passage, etc.
