The invention relates to the technical field of suspension devices, in particular to a suspension device for an automobile engine, which comprises a laminated main body and a connecting arm mounted at the top end of the laminated main body and used for connecting the engine with an automobile body, the laminated main body comprises a wear-resistant outer layer, a damping transition layer arranged on the bottom surface of the wear-resistant outer layer and a tensile core layer arranged on the bottom surface of the damping transition layer, and the wear-resistant outer layer comprises a main body made of a composite ceramic microsphere reinforced polyurethane matrix and a carbon fiber reinforced composite material wrapping the outer layer of the main body. The wear-resistant outer layer reduces vibration energy and prevents the vibration energy from being transmitted to an automobile body, and when the engine vibrates at medium-high frequency, the damping transition layer reduces medium-high frequency vibration energy and prevents the medium-high frequency vibration energy from being transmitted to the automobile body, so that the aim that a worker does not need to periodically detect the suspension device while the automobile engine is fixedly supported is achieved; and the oil leakage condition of the stacked main body is avoided.
本申请涉及悬置装置的技术领域,具体涉及一种汽车发动机用悬置装置,包括层叠式主体以及安装在层叠式主体顶端用于连接发动机与车身的连接臂,层叠式主体包括耐磨外层、设置在耐磨外层底面的阻尼过渡层以及设置在阻尼过渡层底面的抗拉芯层,耐磨外层包括由复合陶瓷微球增强聚氨酯基体制成的主体以及包裹在主体外层的碳纤维增强复合材料,当发动机低频振动时,耐磨外层,降低振动能量,防止其传递到车身上,当发动机中高频振动时,阻尼过渡层降低中高频振动能量,防止其传递到车身上,实现了对汽车发动机进行固定支撑的同时,无需工作人员定期检测悬置装置的目的,且层叠式主体也不会出现漏油的情况。
