The invention belongs to the technical field of exhaust pipes, and particularly relates to an automobile exhaust pipe suspension damping device which comprises a first rubber shell, a second rubber shell, a fixing base, a hoop, a fastening sealing piece, a hoisting damping component and rubber sealing rings. The rubber sealing rings and the first rubber shell are driven by the vibrating silencer to vibrate together, so that the rubber sealing rings slightly move in a staggered mode, and meanwhile, the first rubber shell elastically deforms, so that flexible connection between the silencer andthe exhaust pipe is achieved while automobile exhaust is guaranteed, and meanwhile, the flexible joint between the silencer and the exhaust pipe is sealed through the first rubber shell and the secondrubber shell; flexible connection between the silencer and an automobile chassis is achieved by arranging a hoisting shock absorption part, and buffering and shock absorption are conducted on the vibrating silencer, so that vibration of the silencer is prevented from being transmitted to the vehicle body to generate resonance, noise generated by automobile exhaust is reduced, and then riding comfort is improved.
本发明属于排气管技术领域,具体的说是一种汽车排气管悬吊减震装置,包括一号橡胶壳体、二号橡胶壳体、固定座、抱箍、紧固密封件、吊装减震部件和橡胶密封环;本发明通过震动的消声器带动橡胶密封圈和一号橡胶壳体一起震动,使得橡胶密封圈之间发生轻微的错位移动,同时一号橡胶壳体发生弹性变形,在保证了汽车排气的同时实现了消声器与排气管之间的柔性连接,同时通过一号橡胶壳体与二号橡胶壳体实现了对消声器与排气管之间柔性连接处的密封;通过设置吊装减震部件实现消声器与汽车底盘之间的柔性连接,实现了对震动的消声器进行缓冲和减震,进而避免了消声器的震动传递到车体上产生共振,降低了汽车排气时产生的噪音,进而提高了乘车的舒适性。
