The elastic component connecting powertrain and chassis plays a part in supporting powertrain, isolating the powertrain vibration transmitted to bodywork and the road vibration transmitted to powertrain. The powertrain with excellent shock absorption performance is one of the most important steps to improve the automobile riding comfort and its overall quality.Powertrain mounting system consists of two types - rubber mounts and hydraulic mounts, in which the hydraulic mounts can be divided into conventional (passive), semi-active, and active hydraulic mounts. Due to the introduction of liquid damping devices, hydraulic mounts also have the features of low-frequency high-damping and high-frequency low-rigidity, thus ensuring excellent effects upon vibration control and isolation.
