Abstract

The invention discloses a dual-channel hydraulic suspension of an engine. The is internally provided with a main liquid chamber and a secondary liquid chamber are arranged at the inner part of the hydraulic suspension, wherein an ejection block, a runner plate, a decoupling piece and an iron clapboard are arranged between the main liquid chamber and the secondary liquid chamber; liquid is filled at the inner parts of the main liquid chamber and the secondary liquid chamber, a low-frequency vibration reduction fluid passage and a high-frequency vibration reduction fluid passage are arranged between the main liquid chamber and the secondary liquid chamber; the low-frequency vibration reduction fluid passage is arranged along the ejector block, the runner plate and the iron clapboard, and the high-frequency vibration reduction fluid passage is arranged along the runner plate, the decoupling piece and the iron clapboard. The hydraulic suspension can distinguish between low-frequency vibration and high-frequency vibration of an engine so as to realize isolation, vibration reduction and noise isolation.

Description

technical field [0001] The invention relates to an automobile device, in particular to an engine dual-channel hydraulic mount. Background technique [0002] In the automotive industry, the supports used to support the engine are mostly vibration-damping and vibration-isolating components based on pure rubber, which attenuate vibration energy by the elasticity of the rubber body and its own hysteresis loss. Of course, in order to reduce the impact of engine vibration on the car during driving, attenuate the low-frequency vibration of the engine, isolate the transmission of high-frequency vibration to the car body, and suppress the resonance sound of the car cavity, in the current automotive industry, in order to solve the above problems More and more people are using hydraulic mounts. The common structure of hydraulic mounts is divided into multiple chambers by the upper channel plate, decoupling plate and lower channel plate. Realized intercommunication. Although this stru...
