An engine mount includes: an insulator disposed in a case which has a liquid chamber; an orifice plate dividing the liquid chamber into an upper liquid chamber and a lower liquid chamber, the orifice plate dividing the upper liquid chamber together with the insulator and having an orifice therein for inducing flow of fluid between the upper liquid chamber and the lower liquid chamber; and a diaphragm disposed under the orifice plate inside the case, the diaphragm dividing the lower liquid chamber together with the orifice plate. The orifice plate has a direct passage for enabling the upper liquid chamber and the lower liquid chamber to directly communicate with each other so that liquid flows between the upper liquid chamber and the lower liquid chamber, and includes an opening/closing piston for opening or closing the direct passage.

Engine mount

A semi-active engine mount for a vehicle is provided to improve the NVH performance and ride quality. An engine mount for a vehicle includes a rubber module with a rubber having a core therein, and a case that surrounds an exterior circumference of the rubber and a fluid module with a module case coupled to the rubber module to define an upper and lower chamber and having straight and a bypass flow paths, a closure configured to open or close the straight flow path, and a diaphragm installed on the module case to close the lower chamber. A coil module has a coil embedded in the fluid module and configured to open and close the closure when a power source is turned on or off. In particular, a high loss factor when the vehicle travels is reduced, and decreasing dynamic characteristics when the vehicle idles is decreased.

Engine mount for vehicle

An engine mount for a vehicle, in which of the inside of the engine mount is divided into an upper chamber and a lower chamber by an orifice plate, and an encapsulated hydraulic liquid flows through a center hole provided at the center of the orifice plate in accordance with a change in volume of the upper chamber, is provided. The engine mount is configured to include: a coil which is mounted in the orifice plate and forms a magnetic field in the center hole as electric current is applied; and a drive device which is formed to have a diameter corresponding to a diameter of the center hole, is configured to be inserted and disposed into the center hole, and selectively closes the center hole by moving upwards or downwards in the center hole by the formed magnetic field.

A sound generator apparatus for a vehicle may include a housing and a elastic member arranged at a lower portion of the housing, a driving part including an internal yoke and a magnet, inserted into the housing and disposed on the elastic member to be slid up and down in the housing, a bobbin, an upper end of which is fixed to an inside upper portion of the housing, extended in a downward direction with wrapping the driving part, wherein a coil is wound along a circumference of the bobbin, and an external yoke fixed to the housing in a cylinder shape wrapping the coil and an outside of the internal yoke therein.

Sound generator for vehicle

A structure of engine mounting for supporting a pitch axle in a vehicle may include a front roll mount and a rear roll mount arranged on the pitch axle passing through a powertrain's center of gravity; wherein the weight of an engine is shared by the front roll mount and the rear roll mount.
