Problems solved by technology

When the engine is arranged vertically, the design space of the exhaust pipe may be limited because the engine and gearbox occupy most of the space, and it is impossible to design bellows or rubber bearings
If a shock absorber is not installed, the vibration generated by the engine will be directly transmitted to the exhaust pipe and the body without attenuation, seriously affecting the driving comfort of the vehicle

Abstract

The invention discloses a damping device for an exhaust pipe of an automobile, which is arranged between the exhaust pipe and an engine or a speed changer of the automobile. The damping device comprises a damper fixedly arranged on the exhaust pipe and a connecting part; the first end of the connecting part is fixedly connected with the damper; and the second end of the connecting part is fixedly connected with the engine or the speed changer, and a damping part made of a damping material is arranged at the connection of the connecting part and the engine or the speed changer. The damping device for the exhaust pipe of the automobile, provided by the invention, is simple in structure, durable, good in damping effect and capable of being used under the condition that the space is narrow.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile exhaust pipe damping device. Background technique [0002] At present, especially when the automobile engine is arranged horizontally, rubber bearings are usually added to the exhaust pipe behind the catalytic converter for vibration reduction; or a radial spiral bellows is installed, and the spiral corrugations are arranged in the axial direction , due to the structure of the spiral corrugation, it has axial and radial elasticity and stretchability, which can eliminate vibration and absorb noise when the engine is running. [0003] However, the existing bellows and rubber bearings all have problems such as not durable, easy to wear, and poor vibration damping effect. In addition, both the rubber support and the bellows are wrapped on the outer wall of the exhaust pipe, and their diameter is much larger than that of the exhaust pipe, which requires a relatively...
