Technical field
The utility model is about a kind of suction tude shock-reducing rack module.
Background technique
Intake manifold is an important part in the internal-combustion engine, and it is to improve the air-intake of combustion engine volumetric efficiency, improves ventilation quality, improves the key of power of IC engine and fuel economy.The suction tude support is to support the most frequently used a kind of annex of intake manifold in the internal-combustion engine.The suction tude support directly has influence on the overall noise of life-span, intake efficiency and the internal-combustion engine of intake manifold as the parts of intake manifold fixed support.
In existing various internal-combustion engines, the suction tude support is generally a suction tude and connects support, and suction tude connects support and is rigidly connected by bolt with cylinder head and intake manifold respectively.In this Placement, because automobile causes the vibration of whole internal-combustion engine in startup, stop process, fixedly the suction tude connecting bolt is easy to become flexible, thereby causes the fracture of intake manifold local support position, makes that engine noise is big, vibration is violent, the intake manifold part is short working life.
The model utility content
The purpose of this utility model is to overcome that the engine noise that uses existing suction tude support is big, vibration is violent, part short shortcoming in working life, provides a kind of and can reduce engine noise, reduces vibration and improve the part suction tude shock-reducing rack module in working life.
The utility model also provides a kind of suction tude shock-reducing rack module, this suction tude shock-reducing rack module comprises that suction tude connects support 4, wherein, this suction tude shock-reducing rack module comprises that also cylinder cap connects support 1, bolt bush 2, damper unit 3 and bolt 5, described suction tude connects support 4 and has circular hole, damper unit 3 is installed in this circular hole, and damper unit 3 has circular hole, and bolt bush 2 is installed in the circular hole of damper unit 3; Cylinder cap connects support 1 and has screw, and bolt 5 passes bolt bush 2 and is connected the screw of support 1 with cylinder cap continuous.
Because the suction tude shock-reducing rack module that the utility model provides has damper unit, can cut off effectively vibration X to, Y to Z to transmission, increase the life-span of part effectively, 1kHz-10kHz longitudinal wave velocity is sharply decayed, thereby reduce engine noise.
