The utility model belongs to the technical field of chassis damping accessories, and particularly relates to a chassis suspension.
Background
The suspension system is used as an important element for elastically connecting the power assembly with the auxiliary frame or the chassis of the vehicle body, has a bearing function, and also has the function of isolating vibration generated by the power assembly from being transmitted to the vehicle body so as to reduce the NVH performance of the vehicle.
The typical hydraulic mount attenuates vibration excitation in multiple frequency bands of low, medium and high frequencies of the engine, and also has the ability to reduce transmission of high frequency vibrations in the engine to the vehicle body, suppressing cavity resonance noise in the passenger compartment.
The typical hydraulic mount is constructed such that the upper fluid chamber communicates with the lower fluid chamber through an inertial passage. The mixed liquid in the inertial mass flow path oscillates back and forth in the path, creating an additional damping.
In the prior art, the structural form of the assembly providing the inertia track directly affects the NVH performance of the hydraulic suspension, and particularly, under the increasingly high performance requirements, how to ensure the performance of the bottom hydraulic suspension is of great importance.
We have therefore proposed chassis suspensions to solve the above problems.
