Abstract
The utility model relates to a muffler device of a heavy duty truck, comprising a muffler body. The longitudinal section of the muffler body is a rectangle; thermal baffles are mounted in one side or other outside of the muffler body next to a fuel tank. The muffler device of a heavy duty truck has low exhaust back pressure and high space operating factor and is difficult to be damaged.
Description
Technical field
The utility model relates to the automobile chassis parts of heavy truck, relates to a kind of muffler of heavy truck vehicle chassis component specifically.
Background technique
Silencing apparatus is the important component part of heavy truck exhausting silencer system, and the car load exhausting silencer system requires enough sound deadening capacities, to guarantee the entire car denoise requirement; The silencing apparatus capacity wants enough big simultaneously, exhaust smoothly be arranged to guarantee to satisfy the requirement that reduces exhaust back pressure.In addition, muffler must will have enough intensity and reliability when car load moves.At present, the silencing apparatus that China's heavy truck uses mostly is circular appearance, less to the space availability ratio that general arrangement allowed, may cause the generation of problems such as exhaust back pressure height, and silencing apparatus is very near apart from fuel tank, high temperature during fuel tank work can be delivered to silencing apparatus, causes damage to silencing apparatus.
The model utility content
The utility model is at the deficiencies in the prior art, and it is little to have designed and developed out a kind of exhaust back pressure, and space availability ratio is big, and is difficult for impaired heavy truck muffler.
The utility model is achieved through the following technical solutions:
The muffler of heavy truck includes muffler body, and the longitudinal section of described muffler body is a rectangle.
The muffler of heavy truck, the outside of described muffler body is equipped with thermal baffle.
The muffler of heavy truck, described muffler body is equipped with thermal baffle near a side of fuel tank.
The utility model adopts big capacity square muffler; its objective is the exhausting silencer system big at the heavy truck exhaust sound, that exhaust back pressure is high; reduce exhaust back pressure; improve space availability ratio; reduce and insert loss; in a side thermal baffle is installed, can better be guaranteed the normal use of silencing apparatus, protect it to be without prejudice near fuel tank.
Description of drawings
Accompanying drawing is a structural representation.
Embodiment
Shown in accompanying drawing.
The vertical sectional shape of the utility model muffler body 1 is square; its objective is the exhausting silencer system big at the heavy truck exhaust sound, that exhaust back pressure is high; reduce exhaust back pressure; improve space availability ratio; reduce and insert loss; on near fuel tank one side or other side, thermal baffle 2 is installed, can better be guaranteed the normal use of silencing apparatus, the infringement of high temperature when protecting it not to be subjected to fuel tank work.
Claims (3)
1, the muffler of heavy truck includes muffler body, and the longitudinal section that it is characterized in that described muffler body is a rectangle.
2, the muffler of heavy truck according to claim 1 is characterized in that the outside of described muffler body is equipped with thermal baffle.
3, the muffler of heavy truck according to claim 2 is characterized in that described muffler body is equipped with thermal baffle near a side of fuel tank.
