Problems solved by technology

[0011] However, the conventional hydraulic engine mount has a problem in that noise is generated inside the engine mount due to various factors
[0015] At the same time, there may be cavitation, in which air bubbles (cavities) are created in the fluid, and then according to the change in fluid pressure in the engine mount rupture

Abstract

A hydraulic engine mount may include a nozzle plate including upper and lower nozzle plates, wherein each of the upper and lower nozzle plates may include a rim having an annular shape and forming a peripheral portion of the nozzle plate, a hub disposed at a central portion of the nozzle plate, and ribs connecting the rim and the hub while close contacting and supporting the membrane, and whereinthe contact area between each rib of the upper nozzle plate and the membrane differs from the contact area between each rib of the lower nozzle plate and the membrane.

Description

Technical field [0001] The present invention relates to a hydraulic engine support, and more particularly to an improved hydraulic engine support, which is configured to prevent the generation of noises such as rattling noise and cavitation noise. Background technique [0002] In order to address the continuous development of vehicle technology and the increase in consumer demand for low vibration and low noise, efforts have been made to maximize ride comfort by analyzing noise, vibration, and roughness generated in vehicles. [0003] Engine vibrations generated in a specific RPM range when driving a vehicle are transmitted to the passenger compartment via the vehicle body, while having a specific frequency. The phenomenon exhibited by an explosion in the engine has a major impact on the passenger compartment. [0004] Due to structural factors, such as the periodic center position displacement caused by the vertical movement of the piston and the connecting rod and the periodic cha...
