Problems solved by technology
[0003] The purpose of the present invention is to overcome the problem that the existing hydraulic mounts cannot well realize the vibration damping and isolation of the vibration in the middle frequency region and the high frequency region of the engine, and provide a method that can well control the vibration of the engine in the low frequency region. Vibration damping and isolation, and can also dampen and isolate the vibration of the engine in the mid-frequency region and high-frequency region

Embodiment 1
[0022] Embodiment 1: as figure 1 As shown, an engine hydraulic mount includes a rubber elastic member 1 , a first installation structure 2 and a second installation structure 3 connected to the rubber elastic member, a main fluid chamber 7 and a slave fluid chamber 8 . The upper part of the rubber elastic member 1 is cylindrical, the middle part is conical, and the lower part is bell-shaped. The bottom of the rubber elastic member is provided with a lower end cover 30 and the lower end cover is sealed with the rubber elastic member. The first installation structure 2 is arranged on the upper part of the rubber elastic member 1, and the first installation structure 2 is installed on the engine of the automobile. The second installation structure 3 includes an upper support cover 4, a lower support frame 6 arranged under the upper support cover and connected to the lower end of the upper support cover, and an inner support arranged on the inner side of the lower support frame 6 ...

The invention discloses a hydraulic suspension of an engine, which plays good vibration reduction and noise reduction roles on an engine in a low-frequency area, an intermediate-frequency area and a high-frequency area. The hydraulic suspension comprises a rubber elastic piece, a first installation structure, a second installation structure, a main liquid chamber and a secondary liquid chamber, wherein the first installation structure and the second installation structure are connected with the rubber elastic piece; an upper runner plate, a decoupling piece and a lower runner plate are sequentially arranged between the main liquid chamber and the secondary liquid chamber; liquid is filled in the main liquid chamber and the subordinating liquid chamber; a low-frequency tuning channel, an intermediate-frequency tuning channel and a high-frequency tuning structure are arranged between the main liquid chamber and the secondary liquid chamber; the low-frequency tuning channel is arranged along the upper runner plate and the lower runner plate and is communicated with the main liquid chamber and the secondary liquid chamber; and the intermediate-frequency tuning channel is arranged along the upper runner plate, the decoupling piece and the lower runner plate and is communicated with the main liquid chamber and the secondary liquid chamber.
Description
technical field [0001] The invention relates to an automobile engine support structure, in particular to an engine hydraulic mount. Background technique [0002] In the automotive industry, the supporting structure used to support the engine is generally a vibration-absorbing and isolating component with rubber as the main body, which attenuates vibration energy through the elasticity of the rubber body and its own hysteresis loss. With the advancement of technology, in order to reduce the impact of engine vibration on the car during driving, attenuate the vibration in the low-frequency region of the engine, reduce the transmission of high-frequency vibration to the car body, and suppress the resonance sound of the car cavity, in the current automotive industry Among them, more and more hydraulic mounts are used. The common structure of the hydraulic mount is to divide the interior of the engine mount into multiple cavities by the upper channel plate, the decoupling plate an...
