Abstract

The invention discloses a hydraulic mount, a hydraulic mount assembly, a control method, a control unit, an ECU and an automobile. The hydraulic mount comprises a casing with an inner cavity and a rubber main spring positioned in the inner cavity, wherein the rubber main spring is used for being connected with an engine; the casing is used for being connected with an automobile body; the rubber main spring and the bottom wall of the casing define a hydraulic chamber; the hydraulic chamber is filled with liquid and communicates with the outside through an opening in the chamber wall; the liquid can flow to the outside through the opening; and external liquid can flow towards the hydraulic chamber through the opening. When the rigidity of the hydraulic mount needs to be reduced, the liquid can flow to the outside through the opening in the chamber wall, and the rigidity of the hydraulic mount is reduced; and when the rigidity of the hydraulic mount needs to be increased, the liquid flows to the hydraulic chamber through the opening in the chamber wall, the rigidity of the hydraulic mount is increased, and the adjustment of the rigidity of the hydraulic mount can be realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hydraulic mount and its assembly, a control method, a control unit, an ECU and an automobile. Background technique [0002] At present, vehicles are more and more commonly integrated into the lives of ordinary families. People are also paying more and more attention to the performance indicators of cars. Among them, the low noise of the vehicle has become a very important index of vehicle comfort. As is well known, the engine is a very important source of vibration for a vehicle. In order to reduce the impact of engine vibration on the comfort of the car, an engine mount is set between the engine and the body, and the engine is connected to the body through the engine mount. The vibration of the engine is transmitted to the frame or body through the suspension. Therefore, minimizing the vibration and noise transmission of the engine is the key to improving the ride comfo...
