Automobile exhaust system and exhaust pipe clamp device thereof

Abstract

The invention discloses an automobile exhaust system and an exhaust pipe clamp device thereof. The exhaust pipe clamp device comprises a first arc-shaped outer board and a second arc-shaped outer board which are detachably connected. The first arc-shaped outer board and the second arc-shaped outer board are connected in the manner that openings are opposite. First metal wire damping blocks and first inner boards are sequentially installed inwards on the inner wall of the first arc-shaped outer board. Second metal wire damping blocks and second inner boards are sequentially installed inwards on the inner wall of the second arc-shaped outer board. An installation hole is formed by the first inner boards and the second inner boards. An exhaust pipe penetrates the installation hole and is fastened. Therefore, the metal wire damping blocks are arranged between the corresponding inner boards and outer boards, so that oil dirt and dust are prevented from being accumulated on the damping blocks, and the service life of the damping blocks is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to an exhaust pipe clamp device used in an automobile exhaust system. The present invention also relates to an automobile exhaust system comprising the above-mentioned exhaust pipe clamp device. Background technique [0002] In the automobile exhaust system, the exhaust pipe needs to be fixed by a clamp device, and a shock absorber needs to be installed between the exhaust pipe and the car body bracket to isolate the vibration transmitted from the engine to the frame; with the improvement of emission standards, the exhaust A urea reaction device is often installed in the gas system, and the reaction temperature of the urea tank is 350 degrees Celsius, so the temperature of the exhaust pipe is at least 350 degrees Celsius, and the natural rubber, EPDM rubber and other materials used in traditional shock pads are resistant to high temperatures. The performance cannot meet...

Problems solved by technology

[0002] In the automobile exhaust system, the exhaust pipe needs to be fixed by a clamp device, and a shock absorber needs to be installed between the exhaust pipe and the car body bracket to isolate the vibration transmitted from the engine to the frame; with the improvement of emission standards, the exhaust A urea reaction device is often installed in the gas system, and the reaction temperature of the urea tank is 350 degrees Celsius, so the temperature of the exhaust pipe is at least 350 degrees Celsius, and the natural rubber, EPDM rubber and other materials used in traditional shock pads are resistant to high temperatures. The performance cannot meet the requirements of use; moreover, the driving environment of some models such as heavy trucks is harsh, and the shock absorber is exposed to the environment, resulting in a large amount of oil and dust accumulation, which will cause the performance of the shock absorber to change over time, affecting its use life
