Problems solved by technology

[0011] However, the conventional liquid-filled type engine mounting apparatus has a limitation in reduction of dynamic characteristics in an idling region, and when the dynamic characteristics are reduced by reducing the loss factor, the ride performance during vehicle running is deteriorated.
[0012] In addition, such conventional liquid-filled engine mounts may effectively absorb vertical vibrations generated by the engine, but have difficulty absorbing longitudinal vibrations generated when the engine is started or stopped and during rapid deceleration or deceleration

Abstract

A fluid-filled engine mounting apparatus may include a core provided with a center into which a center bolt is inserted; an insulator with an internal lower portion in which a first fluid chamber is formed and with an upper internal circumferential surface adhered to an external circumferential surface of the core; an upper housing mounted on an upper portion of the insulator; upper and lower orifice plates mounted on an internal circumferential surface of the insulator and are provided with a center hole ; a membrane mounted on the center holes between the upper and lower orifice plates; a first case mounted on a lower external circumferential surface of the insulator; a first diaphragm mounted on a lower portion of the insulator that closes the first fluid chamber; and a longitudinal vibration absorbing device provided at an upper portion of the insulator.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Indian Patent Application No. 20171103708.5 filed with the Indian Intellectual Property Office on October 18, 2017, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a liquid-filled engine mounting device. More particularly, the present invention relates to a liquid-filled engine mounting apparatus that can effectively absorb vibrations generated in the longitudinal direction of a vehicle in addition to absorbing vertical vibrations of the engine. Background technique [0004] Generally, due to the periodic change of the center position along with the vertical movement of the piston and the connecting rod, the inertial force generated by the reciprocating part in the axial direction of the cylinder, and the cyclic change of the rotational force applied to the crankshaft through the connecting rod Etc...
