The invention relates to a power assembly suspension device, and relates to the technical field of automobile accessories. A first support on the device comprises a limiting frame and a main spring. Asecond support is arranged at the top of the main spring and is internally provided with a vibration reduction channel; elastic parts are symmetrically arranged on the two sides of the second support. An accommodating cavity is formed in each elastic part; all the accommodating cavities are respectively communicated with the vibration reduction channel to form a vibration reduction chamber; the damping chamber is filled with damping liquid, the limiting frame is used for controlling displacement of the second support and the power assembly by limiting displacement of the elastic parts, and the elastic part on each side is used for making contact with the corresponding side of the limiting frame in the moving process and driving the damping liquid in the elastic part to flow into the elastic part on the other side after extrusion deformation occurs. The power assembly suspension device solves the problem that at present, when a power assembly is in a large-displacement impact vibrationworking condition, the effect is poor when an elastic part made of single materials such as rubber is independently used for limiting and damping.
本申请涉及一种动力总成悬置装置,涉及汽车配件技术领域。本装置上的第一支架包括一个限位框和主簧,第二支架设于主簧的顶部且其内设有减振通道,弹性件对称设于第二支架的两侧,每一弹性件内均设有一个容纳腔,所有容纳腔分别与减振通道连通以形成减振室,减振室内填充有减振液,限位框用于通过限制弹性件的位移以控制第二支架和动力总成的位移,每一侧的弹性件用于在移动过程中与限位框的对应侧接触并发生挤压形变后驱动其内的减振液朝另一侧的弹性件内流动。本申请提供的动力总成悬置装置解决了目前针对动力总成处于大位移冲击振动工况,单独利用橡胶等单一材料组成的弹性件进行限位和减振时效果较差的问题。
