The invention relates to the technical field of vehicles, and discloses an automobile suspension system which comprises a first support, a second support, a third support and a fourth support, one side of the first support is suitable for being connected with an automobile body, a containing cavity is formed in the first support, and a positioning structure is arranged in the containing cavity; one side of the second support is suitable for being connected with an automobile power assembly, and the second support is connected with the positioning structure; the elastic body is arranged in the containing cavity, the elastic body comprises two elastic bodies which are arranged in a spaced mode, the included angle between the two elastic bodies ranges from 80 degrees to 100 degrees, a rigid structure is arranged in the middle of each elastic body, and the included angle between the two rigid structures is the same as the included angle between the two elastic bodies. Therefore, the dynamic stiffness characteristic of the suspension system can be obviously changed in frequency response, an original broadband wave crest is converted into a structure in which a narrow-band wave crest and a narrow-band wave trough are alternated, and the automobile suspension system has low dynamic stiffness in a specific frequency range. Therefore, the phenomena of high-frequency noise and vibration such as howling during the working of the automobile electric drive are effectively reduced or eliminated.

    本发明涉及车辆技术领域,公开了一种汽车悬置系统,包括:第一支架,一侧适于连接汽车车身,第一支架上设有容置腔,容置腔内设有定位结构;第二支架,一侧适于连接汽车动力总成,第二支架与定位结构连接;弹性体,设于容置腔内,弹性体包括两个间隔设置的弹性本体,两个弹性本体之间的夹角处于80°‑100°,每个弹性本体的中部位置设有刚性结构,两个刚性结构之间的夹角与两个弹性本体之间的夹角相同。这样使得悬置系统的动刚度特性在频率响应上能够发生显著变化,使得原先的宽频波峰转变为窄频波峰和波谷相间的结构,使得汽车悬置系统在特定频率范围内具有较低的动刚度,从而有效减少或消除汽车电驱工作时的啸叫等高频噪声和振动的现象。
