The invention relates to a semi-active
particle damping rubber suspension device for a power
assembly. According to the technical scheme of the semi-active
particle damping rubber suspension device for the power
assembly, the middle of a rubber spring (3) is coaxially embedded in a connecting framework (2), and the open end of the rubber spring (3) is fixedly connected with the open end of a suspension shell (5) in a face-to-face mode through a steel ring (4). The upper end face and the lower end face of an outer steel
pipe (11) are coaxially connected with the lower plane of the connecting framework (2) and the upper plane of a base plate (10) correspondingly, the upper end face and the lower end face of an inner steel
pipe (12) are coaxially connected with the lower plane of the connecting framework (2) and the upper plane of the base plate (10) correspondingly, steel balls (14) are contained in a damping cavity (15), and the volume of the steel balls (14) is 50%-80% of the volume of the damping cavity (15). An
electromagnetic coil (13) is installed on the outer wall of the outer steel
pipe (11) and is located on the upper plane of the base plate (10), the
electromagnetic coil (13) is externally connected with a controller of a suspension
assembly through a coil socket (6) which is fixed to the suspension shell (5), and the coil socket (6) is fixed to the suspension shell (5). The semi-active
particle damping rubber suspension device for the power assembly has the advantages of being simple and reliable in structure, convenient to manufacture and low in cost, and the
wideband vibration isolation performance, the vibration reduction performance and the
noise reduction performance are achieved.
