Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of turbochargers, in particular to a shock-absorbing and noise-reducing turbocharger unit. Background Technique
[0002] A turbocharger is a device used to increase the intake air volume of an internal combustion engine, thereby improving the power and efficiency of the engine. The high-temperature exhaust gas discharged from the engine drives the turbine impeller of the turbine part to rotate at high speed. Since the turbine impeller and the compressor impeller are connected by a shaft, the rotation of the turbine impeller will drive the compressor impeller to rotate synchronously. The compressor impeller is responsible for sucking and compressing the outside air, and then delivering the high-pressure and high-density air to the engine intake manifold, so that the engine can inhale more air and make the fuel burn more fully. In modern life, in order to better protect the components around the turbocharger, a shock-absorbing and noise-reducing turbocharger is needed.
[0003] The existing shock-absorbing and noise-reducing turbocharger unit mainly consists of a compressor, a turbine, an intermediate body, a bypass valve, an intercooler and noise insulation and reduction components. If the noise and vibration generated during the operation of the turbocharger are not effectively controlled, they will be directly transmitted to the driving space, seriously affecting the comfort experience of driving. To solve the above problems, the existing technology only pastes sound-absorbing materials on the inner walls of the turbine housing and the compressor housing. The sound-absorbing cotton has good sound-absorbing performance and can absorb the noise generated when the turbine impeller and the compressor impeller rotate, effectively reducing the noise transmission. However, in the case of frequent vibration, the sound-insulating material is easy to loosen and fall off, thus affecting the sound-absorbing effect. Moreover, when replacing the sound-insulating material, it is necessary to disassemble the turbocharger, and the operation process is complex and difficult, which cannot meet the use requirements.
