Technical Field

The invention relates to the field of hydraulic suspension, in particular to a decoupling diaphragm structure for hydraulic suspension.

Background

The hydraulic mount is a common component of an automobile and is used for supporting an engine to form a damping structure. The decoupling diaphragm is arranged inside the hydraulic suspension, when high-frequency small-amplitude vibration occurs, the damping liquid is nearly immobile due to the action of the internal inertia channel of the hydraulic suspension, and the decoupling diaphragm vibrates along with the damping liquid in the decoupling channel at the moment so as to reduce the high-frequency dynamic stiffness of the hydraulic suspension and play a role in damping. The decoupling membrane in the prior art is arranged in a decoupling channel, and easily collides with the inner wall of the decoupling channel at the mounting position, so that the problem of high noise exists.
