Active engine mount for vehicle |
摘要 |
An active engine mount for a vehicle includes an upper body which has a main rubber and an upper liquid chamber, and a lower body which is coupled to a lower portion of the upper body. An orifice circular plate divides an interior of the upper and lower bodies into the upper liquid chamber and a lower liquid chamber inside the upper and lower bodies, and has an orifice through which a fluid flows between the upper and lower liquid chambers. A diaphragm is installed below the orifice circular plate inside the upper and lower bodies, and forms the lower liquid chamber. A semi-active mount is in contact with a central portion of the diaphragm by a plunger inside the lower body, and operates by an electromagnet. |

1. An active engine mount for a vehicle, comprising:
an upper body which has a main rubber and an upper liquid chamber; a lower body which is coupled to a lower portion of the upper body; an orifice circular plate which divides an interior of the upper and lower bodies into the upper liquid chamber and a lower liquid chamber inside the upper and lower bodies and which has an orifice through which a fluid flows between the upper and lower liquid chambers; a diaphragm which is installed below the orifice circular plate inside the upper and lower bodies and which forms the lower liquid chamber; a semi-active mount which is in contact with a central portion of the diaphragm by a plunger inside the lower body and which operates by an electromagnet, a hole which is formed at a central portion of the orifice circular plate; a first fluid entrance hole which is formed at an end of the edge of the orifice to communicate with the lower liquid chamber and a second fluid entrance hole which is formed at an opposite end of the orifice at the central portion of the orifice circular plate to communicate with the upper liquid chamber; and a switching valve is configured to selectively open or close the hole in a position to cover the hole at the central portion of the diaphragm and to compressively deform by pressure of the fluid in the upper liquid chamber. |
