Embodiment 1
[0021] Such as figure 1 , figure 2 with image 3 As shown, an air spring type semi-active control hydraulic mount is provided, which includes a mount housing 1 (certainly also includes other parts, but because it does not involve the invention of the present invention, it will not be repeated here) One end of the suspension housing 1 is provided with a rubber main spring 2, and the other end of the suspension housing 1 is provided with a bottom bowl 3; the suspension housing 1 is provided with an inertia channel 4 and a decoupling chamber 5. The decoupling chamber 5 is provided with a decoupling diaphragm 6, and the decoupling diaphragm 6 separates the decoupling chamber 5 into the liquid chamber 5.1 and the air chamber 5.2, and the liquid chamber 5.1 communicates with the inertial channel 4, The suspension shell 1 is provided with a through hole 7 communicating with the air chamber 5.2, the inner wall of the through hole 7 is a truncated cone structure, and the inner wall ...
Embodiment 2
[0026] Such as Figure 4 As shown, the inertia passage 4 is provided with at least two damping holes 10 (two in this example).
[0027] There are two damping holes 10 , and the two damping holes 10 are respectively arranged at the starting point and the ending point of the outermost ring of the inertial passage 4 .
Embodiment 3
[0029] Such as Figure 5 As shown, there are three damping holes 10, and the three damping holes 10 are arranged on the outermost channel of the inertial passage 4, and the three damping holes 10 are evenly distributed along the circumferential direction.
