Abstract

A hydraulic engine mount capable of preventing rattling noise, improving noise vibration and harshness performance by reducing the dynamic characteristics of a hydraulic engine mount at idle, and capable of producing high Damping value, a hydraulic engine mount comprising: a housing with hydraulic fluid sealed therein; a nozzle plate having a lower nozzle plate and an upper nozzle plate coupled to the upper portion of the lower nozzle plate and dividing the housing interior into an upper fluid chamber and a lower fluid chamber The fluid chamber; the first diaphragm is arranged on the upper part of the lower nozzle plate, so that the first edge portion of the first diaphragm is tightly coupled to the upper part of the lower nozzle plate, and is provided with at least one first communication hole; the second diaphragm is arranged on the upper nozzle The lower part of the plate, so that the second edge portion of the second diaphragm is tightly coupled to the lower part of the upper nozzle plate, and is provided with at least one second communication hole; and a separation plate, allowing the first and second diaphragms to be separated from each other, to A flow space is provided between the second membrane and the second diaphragm.

Description

technical field [0001] Embodiments of the present disclosure relate to a hydraulic engine mount provided with a diaphragm having an improved structure for mounting to a nozzle plate. Background technique [0002] The engine of the vehicle is installed in the engine room of the vehicle body through an engine mount in order to isolate and damp vibration of the engine. Rubber mounts that isolate and damp vibrations by the elastic force of rubber, and hydraulic engine mounts (fluid-filled type engine mounts) sealed with a predetermined amount of hydraulic fluid have been widely used in passenger vehicles. [0003] The hydraulic engine mount has a structure in which a predetermined amount of hydraulic fluid is sealed to attenuate vibration according to the flow of the hydraulic fluid, and has an effect of simultaneously attenuating vibration in high frequency ranges and low frequency ranges. Therefore, the application range of the hydraulic engine mount increases. [0004] The ...
