Abstract

The invention discloses a suspension device of an automotive exhaust system capable of adjusting the angle of a lifting lug, comprising the lifting lug, a connection pin I, a connection pin II, a support I provided with a chute and a support II provided with a chute, wherein, the connection pin I and the connection pin II are connected with the support I and the support II through the chutes, and are connected with the lifting lug. The suspension device of the invention can conveniently adjust the installation angle of the lifting lug relative to the automotive body, can adjust the lifting lug at any time according to actual conditions, and eliminates covibration to the greatest extent, thus leading the transmission amount of the vibration of the exhaust system to the automobile body to reach the lowest value, improving comfort of a control cabin, reducing noise pollution and prolonging the service life of the suspension device; and meanwhile, when a vibration test of the exhaust system is performed, multiple different suspension devices need not to be manufactured, thus large scale adjustment of the lifting lug angle is realized, thereby realizing tests of lifting lugs at different installation angles, which has an important significance in improving work efficiency, shortening development cycle and lowering development cost in the development process of automobiles.

Description

technical field [0001] The invention relates to an automobile accessory part, in particular to an automobile exhaust system suspension device capable of adjusting the angle of lifting lugs. Background technique [0002] Exhaust system is one of the important assemblies of automobiles. It plays a very important role in purifying exhaust emissions and reducing engine exhaust noise. This is of great significance to the current problems of traffic noise and motor vehicle exhaust pollution faced by cities. [0003] The exhaust system is generally composed of a slender and curved pipe, a catalytic converter, a muffler and an exhaust tailpipe. The exhaust system of a car is connected to the body of the car through several mounts. These mounts consist of a hook connected to the body, a hook connected to the exhaust system, and elastic element lugs connecting the pair of hooks. [0004] Due to the vibration of the engine, the excitation of the exhaust airflow and the influence of t...
