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.
Description
technical field [0001] The present application relates to the technical field of auto parts, in particular to a powertrain suspension device. Background technique [0002] At present, the main functions of the mount as a key component connecting the powertrain and the body include support, limit and vibration isolation. The weight of the powertrain and various driving moments will cause various vibrations on each mount. A static load and a dynamic load, the suspension is used as the main part connecting the powertrain and the body to carry various loads of the power unit. The suspension is mainly composed of three parts: the active end bracket, the passive end bracket and the elastic member connecting the active and passive end brackets. Among them, the active end bracket is connected to the powertrain, and the passive end bracket is directly or indirectly connected to the vehicle body. [0003] In the related art, the part where the suspension plays a bearing role is mainl...
