Abstract
The invention discloses an electronic controlled hydraulic mount, comprising a housing base, a rubber spring, a metallic framework, and a bottom film. The middle part of the housing base is provided with a partition. The partition and the rubber spring, and the partition and the bottom film respectively form a sealed upper liquid chamber and a lower liquid chamber. A part of the partition is provided with orifices communicating the upper liquid chamber with the lower liquid chamber. The lower liquid chamber is internally provided with a motor. The output shaft of the motor is fixedly sleeved with a throttling valve board. The upper surface of the throttling valve board is abutted against the lower surface of the partition. When the motor is started, the throttling valve board can control on-off of the orifices. The electronic controlled hydraulic mount uses the motor to control on-off of the orifices, so as to control dynamic characteristics of the hydraulic mount, and the hydraulic mount satisfies requirements of vibration reduction in different working conditions.
