The mounting system connects the powertrain to the vehicle body and serves as the primary structural-borne noise transmission path for powertrain NVH. Its core functions are as follows: Support the powertrain: The mounting system must bear the weight of the powertrain and prevent excessive static displacement. Restrict powertrain displacement: When the powertrain is subjected to various disturbance forces (braking, acceleration, deceleration, etc.), the mounting system can effectively limit its maximum travel to avoid collision and interference with adjacent components. Vibration isolation: The powertrain mount system shall attenuate and isolate vibrations transmitted from the powertrain to the vehicle frame as much as possible. Meanwhile, it also suppresses vibrations transferred from the frame to the powertrain caused by uneven road surfaces.
