Abstract

The utility model relates to a technical field of automobile brake system, especially a kind of vibration isolation and noise reduction structure of automobile brake booster device, including automobile brake booster device ontology, wherein, the end face of mounting flange plate is covered with rubber interlayer, for forming vibration isolation interface between mounting flange plate and car body front wall;At least part of rubber interlayer extends along mounting stud axial direction and wraps the root of mounting stud, to form annular hole plug, for plugging stud through hole on car body front wall.The utility model forms vibration isolation interface between mounting flange plate and car body front wall by rubber interlayer, effectively attenuates the vibration transmission of automobile brake booster device ontology to car body front wall, inhibits sound radiation, reduces cockpit noise.Meanwhile, stud through hole on car body front wall is plugged by annular hole plug, realizes hole periphery seal, blocks the air sound transmission path of engine compartment noise through stud through hole, further reduces cockpit noise, improves driving comfort.
