Embodiment Construction

[0027] figure 1 is a view showing the configuration of an electronic SAC engine suspension with a variable air chamber according to an embodiment of the inventive concept.

[0028] refer to figure 1 , electronic SAC engine suspension 1 includes upper and lower fluid chambers 10-1 and 10-2, channel connection plate 10-3a, channel connection cover 10-3b, upper and lower cores 20-1 and 20-2, main diaphragm 30. Mounting case 40, variable air chamber unit 50 having variable air chamber 90, and controller 100 controlling variable air chamber unit 50 according to engine revolutions per minute (RPM) to form Or remove the variable air chamber 90.

[0029] The upper and lower fluid chambers 10-1 and 10-2, the channel connection plate 10-3a and the channel connection cover 10-3b form a fluid storage part in the electronic SAC engine suspension 1, and form a fluid circulation for improving low-frequency dynamic characteristics structure. The upper fluid chamber 10-1 and the lower flui...

Abstract

An electronic semi active control engine mount having a variable air chamber includes a variable air chamber diaphragm that absorbs the exciting force of fluid due to an external force by elastically deforming. An air chamber supports the variable air chamber diaphragm with the atmospheric pressure. A fork is separated from the diaphragm to keep the air chamber into which air flows in idling of an engine, and comes in close contact with the variable air chamber diaphragm to remove the air chamber into which the air flows when a vehicle is driven. An actuator either separates the fork from the variable air chamber diaphragm or allows the fork to be in close contact with the variable air chamber diaphragm.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2014-0152031 filed on November 4, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present application relates to an electronic semi-active control engine suspension, and more particularly to an electronic semi-active control engine suspension with a variable air chamber that can increase the rate of change of dynamic characteristics and loss factor. Background technique [0004] Vehicles are equipped with a semi-active control (SAC) engine suspension disposed between an engine or a powertrain and a vehicle body to effectively reduce vibration occurring during operation of the engine by turning on / off dynamic characteristics. [0005] The SAC engine mount has an air chamber connected to the air supply passage and an internal passage connecting first and second fluid chambers separated by a...
