Suspending device for vehicle exhaust system

Abstract

The invention discloses a suspending device for a vehicle exhaust system. The suspending device comprises a lifting hook body consisting of a straight section and a downwards bent vertical section, and an L-shaped lifting hook connected to the lower end of the vertical section of the lifting hook body, wherein a horizontal section of the lifting hook is vertical to the straight section of the lifting hook body; an L-shaped connection rod is connected with the middle part of the vertical section of the lifting hook body; a horizontal section of the connection rod is parallel to the horizontal section of the lifting hook; an installation opening for a muffler inlet pipe is formed between the lower surface of the connection rod and the upper surface of the lifting hook; and the muffler inlet pipe is clamped in the installation opening. The suspending device has a simple structure; a supporting force on the exhaust system is increased; and the problem of severe shaking of the exhaust system under the condition of sudden turning of a vehicle or a worse road condition is solved, the rigidity of the whole lifting hook is enhanced, and an interference phenomenon probably arisen during movement of the exhaust system and surrounding parts can be avoided.

Description

technical field [0001] The invention relates to a hook structure of an exhaust system of a motor vehicle, in particular to a hanging device of an exhaust system of an automobile. Background technique [0002] According to the temperature, the exhaust system of a motor vehicle can be divided into two parts: hot end and cold end. The part closer to the engine is the hot end, including the exhaust manifold and catalytic converter; the farther part is the cold end, including the muffler, Muffler inlet pipe, intermediate connecting pipe, tailpipe and hook, etc. In general, 3 to 4 hooks are arranged at the cold end. These hooks not only need to support the entire cold end, but also need to meet certain rigidity requirements: on the one hand, it is necessary to avoid resonance, and on the other hand, try not to generate new vibrations ; Especially in the case of long cold-end pipes and hook arms, the exhaust system shakes greatly, and there is a risk of interference with surroundi...

AI Technical Summary

Problems solved by technology

The existing hook structure of the automobile engine exhaust system is composed of the hook body and the hook, and there is only one fixed point between the cold end pipe and the rigidity is too small, which cannot meet the NVH performance index of the exhaust system
