Abstract

The invention belongs to the technical field of automobile parts, and in particular relates to an automobile hydraulic mounting structure and an automobile. The automobile hydraulic mounting structure includes a main spring assembly, a leather cup assembly and a flow channel assembly; the main spring assembly is provided with an upper liquid chamber; the leather cup assembly is provided with a lower liquid chamber; the flow channel assembly includes a flow channel tube, a decoupling Membrane and flow channel framework; the flow channel framework is provided with mounting through holes, upper flow channel holes and lower flow channel holes; the decoupling membrane is installed in the mounting through holes and used to separate the upper liquid chamber and the lower liquid chamber; one end of the flow channel pipe The flow channel frame is connected to the upper liquid chamber through the upper flow channel hole, and the other end of the flow channel pipe is connected to the flow channel frame through the lower flow channel hole and communicated with the lower liquid chamber. In the present invention, the length and cross-sectional area of ​​the flow conduit can be easily changed by placing the flow conduit outside, so that the automobile can obtain higher damping characteristics under low frequency and large amplitude, and the shape and stiffness of the decoupling membrane can be adjusted at the same time. The space is larger, and the car can obtain lower dynamic stiffness characteristics at high frequency and small amplitude.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to an automobile hydraulic suspension structure and an automobile. Background technique [0002] Automobile suspension refers to the elastic connection system between the automobile engine assembly and the frame, which has good shock absorption performance and can reduce the transmission of the vibration of the automobile engine to the vehicle body. Ordinary rubber suspensions are widely used due to their low price and simple structure. However, rubber mounts cannot meet the characteristic requirements of large damping when the car is in low frequency and large amplitude vibration, nor can it meet the characteristic requirements of small stiffness and small damping when the car is in high frequency and small amplitude vibration. [0003] Automotive hydraulic mount is a rubber structure based on adding a liquid damping mechanism, which has good frequency convers...
