Disclosed is an engine mount for a vehicle including a membrane, which is an essential component of an engine mount for supporting a powertrain of the vehicle. The membrane may be deformed vertically and radially depending on an input amplitude so as to open or close bypass holes in upper and lower plates depending on the input amplitude. As such, it is possible to easily fulfill a function of isolating vibrations generated by the powertrain during idling and a damping function of controlling the behavior of the powertrain during traveling and it is possible to prevent the generation of abnormal noise attributable to cavitation and rattling phenomena.

The present disclosure relates to an hydraulic mount for coupling first second components in a vehicle. The mount has a first elastomeric member defining a first portion of a first chamber, and a second elastomeric member defining a second portion of the first chamber and a second chamber. The chambers are each able to retain fluid in a liquid seal manner. An inner tube assembly defines an opening for receiving a bolt. The elastomeric members may be fixedly secured to an outer surface of the inner tube assembly. An inner ring is fixedly coupled to the inner tube assembly at a position between the two chambers. The second elastomeric member is fixedly secured to an outer surface of the inner ring. A decoupler is fixedly disposed within the inner ring and adapted to move between rigid surfaces adjacent the first and second chambers.

A liquid-filled bushing (1) includes an inner tube (11) and an outer member (12). The outer member (12) defines a pair of liquid chambers between the outer member (12) and the inner tube (11), and an orifice portion (13) in which an orifice passage (24) which communicates with the liquid chambers is formed. An elastic body (14) which elastically connects together the orifice portion (13) and the inner tube (11) is provided. The pair of liquid chambers are individually disposed on both sides between which the inner tube (11) is interposed. A first protrusion portion (11a) which protrudes outward in the radial direction and is fitted into the elastic body is formed in the inner tube (11), and a second protrusion portion (28) which protrudes inward in the radial direction and is fitted into the elastic body (14) is formed in the orifice portion (13). The first protrusion portion (11a) and the second protrusion portion (28) are disposed in both portions between the pair of liquid chambers adjacent in a circumferential direction such that positions of the portions in the circumferential direction coincide with each other and positions of the portions in the direction of the center axis are different from each other.
