Problems solved by technology

Resistant mufflers are suitable for eliminating middle and low frequency noises, but the occupants still tend to feel uncomfortable with existing vehicles with resistant mufflers installed on the air filter, indicating that high-frequency noise has a greater impact on ride comfort. At the same time, high-frequency noise can make people feel restless and easily excited, which can easily lead to accidents, which makes the vehicle a potential safety risk

Abstract

The invention discloses an air filter and a vehicle. The air filter comprises a shell, an air filter core and a silencer, wherein the shell is provided with an air channel, the air filter core is located in the air channel, and the silencer is communicated with the air channel. The air filter is characterized in that the silencer comprises a sound absorption tube (3) made of absorption material, and the sound absorption tube (3) is installed on the inner wall of the air channel in a sleeved mode. The sound absorption tube installed on the inner wall of the air channel in the sleeved mode is used for improving the silencing capacity of the air filter and particularly good in intermediate-high frequency noise elimination effect, so that riding comfort of the vehicle is improved, and potential safety risks of the vehicle are reduced to a certain degree. Meanwhile, the sound absorption tube and the air filter are of an integrated structure, so that installation space of an engine room of the vehicle is saved, and platform-based designing and light weight designing of the vehicle are facilitated.

Description

technical field [0001] The present invention relates to the technical field of noise reduction, in particular to an air filter and an air filter including the air filter. Background technique [0002] With the development of modern industry, environmental pollution is also produced. Noise pollution is a kind of environmental pollution, which has become a great harm to human beings. In order to effectively prevent and control such hazards, in the late 1970s, the international community began to formulate a series of noise regulations, such as vehicle noise regulations, to reduce noise pollution to the environment. With the development of society, the requirements for vehicle noise are becoming more and more stringent. At the same time, in addition to paying attention to the power, fuel economy, braking performance, handling stability and other performances of the vehicle, the current consumers pay more and more attention to the ride comfort of the vehicle when purchasing a v...
