Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of auto parts. In particular, it relates to a powertrain semi-active particle damping rubber mount. Background technique [0002] In recent years, automobile design has developed towards light weight and economy, but the application of fewer cylinders, high-power engines and lightweight frame (body) will lead to intensified vibration transmitted from the engine to the body, deteriorating the vibration and noise characteristics in the car . Especially for front-engine-front-wheel-drive cars with poorly balanced four-cylinder four-stroke engines, the vibration of the powertrain has an increasingly prominent impact on the ride comfort of the car. At the same time, people's requirements for riding comfort are constantly improving. In order to solve these contradictions, it is necessary to improve the isolation effect of the powertrain mount on the vibration transmission between the powertrain and the vehicle ...
