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.
