Abstract

The invention discloses a suspension device and relates to the technical field of vehicle accessories. The suspension device not only can effectively restrain large-displacement vibration of an engine, but also can effectively attenuate vibration after the engine is stabilized. The suspension device comprises a device body, a vibration reduction structure is arranged at one end of the device body and connected with the engine, and an installing hole is formed in the other end of the device body and connected with an auxiliary frame. The vibration reduction structure comprises a connecting part and an elastic vibration reduction body, wherein the connecting part is fixedly connected with the engine, and the elastic vibration reduction body is provided with an installing groove and cavities. The elastic vibration reduction body is fixedly connected with the device body, and the connecting part is located inside the installing groove and seals the cavities. The cavities are filled with hydraulic oil. The surfaces, located inside the cavities, of the connecting part are provided with first elastic parts, and second elastic parts are arranged on the inner surface of the elastic vibration reduction body, wherein the second elastic parts and the first elastic parts are arranged in a staggered mode. When the engine moves and drives the connecting part to move, the first elastic parts move and are attached to the second elastic parts so that each cavity can be divided into two independent chambers. The suspension device is mainly applied to an automobile.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a suspension device. Background technique [0002] Nowadays, with the continuous improvement of automobile research and development technology and people's living standards, people's requirements for the power and ride comfort of automobiles are also getting higher and higher. At the same time, good NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance is also the goal that people have been pursuing. [0003] Among them, the engine is the power source of the car, how to effectively attenuate the vibration of the engine has become an effective means to improve the NVH performance. Specifically, the engine is connected to the subframe through the suspension device, so that through the damping effect of the suspension device, the vibration of the engine is attenuated, and then transmitted to the subframe and the body, thereby improving the NVH pe...
