Active control type hydraulic mount of automobile power assembly

Abstract

The invention discloses an active control type hydraulic mount of an automobile power assembly. An upper liquid chamber is formed by a mount shell and a driven disk, and a rubber check ring is respectively in vulcanization connection with the mount shell and the driven disk, so that the upper liquid chamber is sealed; a lower liquid chamber is formed by the driven disk, a base membrane and an actuating ejection rod, and a sealing ring is installed in the base membrane and makes contact with the actuating ejection rod, so as to prevent liquid leakage; an actuator is in threaded connection with the actuating ejection rod, and the actuating ejection rod is connected with the driven disk; an inertial channel is formed in the driven disk, so that the upper liquid chamber communicates with the lower liquid chamber. The active control type hydraulic mount is improved on the basis of an original hydraulic mount, the structure is simple, and partial components and parts are versatile. Active control is realized by utilizing the actuator and can adapt to the action of wide-frequency excitation force generated by a power assembly system, the transferring of vibration of the power assembly to an automobile frame is obviously reduced, and the vibration and noise which are generated by the power assembly system are effectively isolated. The active control type hydraulic mount has the characteristics of low cost, simplicity in manufacturing, good reliability and the like.

Description

Technical field [0001] The invention relates to an automobile vibration isolation component, in particular to an active control hydraulic suspension and a vibration isolation method of an automobile powertrain. Background technique [0002] With the continuous improvement of the quality of life, people have higher and higher requirements for car performance. Especially riding comfort, it has become an important indicator to measure car performance. As the vehicle powertrain is an important factor that causes vehicle vibration and noise, the isolation of the vibration caused by it becomes the key to improve the NVH (Noise, Vibration, Harshness, noise, vibration and harshness) characteristics of the vehicle. The suspension is a bridge that connects the powertrain and the car body, and is the path of vibration transmission between the powertrain and the car body. The powertrain suspension system with good vibration isolation can reduce the transmission of powertrain vibration to t...
