The utility model relates to a car damping element field, specific changeable hydraulic pressure bush in inertia passageway cross -section that says so. This bush includes metal coat, metal framework, metal endotheca, nylon stopper, liquid chamber, rubber main spring and two -way valve, and metal coat overlaps and interference fit on metal framework, the metal framework cover is at the rubber main spring surface and become integrative rather than vulcanizing, metal endotheca company and nylon stopper fixed connection, the metal endotheca is as an organic whole with the interior surface vulcanization of rubber main spring, rubber main spring both ends symmetrical arrangement has two liquid chambers, and two liquid chambers pass through inclined inertia passageway and link to each other. The utility model relates to an increase an aperture along with pressure variation's the two -way valve of opening at traditional hydraulic pressure bush, can guarantee all to have in the broad frequency range better damping to
