Problems solved by technology

However, on the current semi-active support base, it is necessary to apply a coil with a high capacitance corresponding to the stiffness of the rubber spring, and because a large number of parts are required, the cost and weight are greatly increased, and its structure is relatively complicated
Current semi-active bearing mounts are disadvantageous in terms of packaging due to their larger size than existing hydraulic bearing mounts

Abstract

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.

Description

technical field [0001] The present invention relates to an engine support seat for a vehicle, more particularly to a semi-active engine support seat for a vehicle, which can reduce the dynamic characteristics of the support seat when the vehicle is idling and increase the loss when the vehicle is running factor to improve noise, vibration and harshness (NVH) performance and ride quality. Background technique [0002] In general, engine mounts prevent the transmission of engine vibrations to the body, isolate the vehicle's vibration modes, and control engine motion. By making the engine mounts hard static, the engine mounts minimize the movement of the engine and by making the engine mounts soft dynamic, isolate high frequency vibrations. [0003] Generally, engine mounts made of rubber materials have the disadvantages of being vulnerable to low-frequency damage and large-displacement vibrations. Therefore, the engine support seat cannot satisfy high-frequency low-amplitude...
