Have you ever thought about it?,Why is the engine and gearbox running,You can't feel vibration in the car.?

Have you ever thought about it?,Why is the car driving on the bumpy road,You can't hear the sound of friction between the metal?

Have you ever thought about it?,Why will we always say that this car feels very soft or feel very hard??What is this transferred??

Be right,This is the truck bushing!The bushing has a seismic、Resist、Extend the life of the parts、Improve comfort,A small bushing,Have such a big magic!

Bushing advantages:1、Elastic modulus small,Good vibration isolation;2、Avoid resonance phenomena;3、Vulcanization,light in mass;4、Good viscoelasticity,Good noise reduction;No need to maintain and maintain。

Good and bad designs,Can directly reactivate the car's performance,Therefore, high quality bushing is critical!
