Hydraulic suspension decoupling vibration isolation device

Abstract

The invention discloses a hydraulic suspension decoupling vibration isolation device which comprises a valve body. The valve body comprises a through hole and a flow channel, the through hole is formed in the valve body, and the flow channel is formed in the outer surface of the valve body. A flow channel opening is formed in the flow channel, and the through hole communicates with the flow channel through the flow channel opening. A decoupling disc and a flow limiting plate are arranged in the through hole, clearing holes are distributed in the flow limiting plate, the horizontal height of the flow limiting plate is higher than that of the flow channel opening, and the upper surface of the flow limiting plate is covered with the decoupling disc; the position of the decoupling disc is limited through the flow limiting plate, so that the decoupling disc is located at the position convenient to open, then the damping liquid can open the decoupling disc when moving upwards, the damping effect is guaranteed, the situation that the decoupling disc blocks the through hole, negative pressure is generated in a liquid chamber, and accordingly abnormal sound of a cavity is caused is avoided, and the riding experience of a vehicle is further improved; and through the distributed clearing holes, the damping liquid is more stable when passing through the flow limiting plate, and then the damping effect of the device is more stable.

Description

technical field [0001] The invention relates to the field of design and manufacture of shock absorbing devices, more specifically, to a hydraulic mount decoupling vibration isolation device. Background technique [0002] The hydraulic vibration isolation device is a commonly used vibration isolation device in existing equipment. Compared with other types of vibration isolation devices, the vibration isolation effect of the hydraulic vibration isolation device is more gentle and stable; therefore, it is often used in automobiles. To bring passengers a good and comfortable ride experience; [0003] In the traditional hydraulic mount decoupling vibration isolation mechanism, when the damping fluid moves upward, the liquid cannot open the decoupling plate, and the lower liquid chamber will generate negative pressure, resulting in cavitation noise; the failure of the decoupling plate to open will affect the damping fluid. The backflow leads to poor shock absorption effect of the...

[0003] In the traditional hydraulic mount decoupling vibration isolation mechanism, when the damping fluid moves upward, the liquid cannot open the decoupling plate, and the lower liquid chamber will generate negative pressure, resulting in cavitation noise; the failure of the decoupling plate to open will affect the damping fluid. Backflow, resulting in poor shock absorption effect of the decoupling vibration isolation mechanism of the hydraulic mount, and the abnormal noise generated by the negative pressure of the lower liquid chamber will also affect the car experience
