Fully isolated type adjustable-rigidity rubber suspension system

The utility model provides a fully isolated type adjustable-rigidity rubber suspension system and belongs to the field of automobile technology. According to the utility model, a sleeve pipe is sleeved on the middle part of a bolt; a rubber block I, one end of a connecting rod II, a rubber block II, one end of a connecting rod I and a rubber block III are sequentially sleeved on the sleeve pipe; a compaction sheet I and a compaction sheet II are respectively arranged on upper and lower ends of the bolt and are respectively fixed by a nut I and a nut II; the other end of the connecting rod I is fixedly connected with a vehicle frame; the other end of the connecting rod II is fixedly connected with a silencer assembly or a post processor assembly; and the sleeve pipe can be lengthened or shortened according to the amount of compression needed by the rubber block I, the rubber block II and the rubber block III, so actual rigidity characteristic requirements can be easily satisfied. Via the system, vibration transmitted between the vehicle frame and the silencer assembly or the post processor assembly can be effectively reduced, and the system is simple in structure, adjustable in rigidity and capable of satisfying vibration attenuation requirements of an exhaust system and a whole vehicle.
