Problems solved by technology

These defects in design, installation and cost limit the scope of application of this type of muffler, and also delay the design and production cycle of the whole vehicle
[0006] At present, domestic and foreign mainstream passenger car manufacturers use resistant mufflers on the air pump intake system. This muffler has complex structure, high cost, large volume, and difficult installation. Difficulties
It cannot be used in a wide range of high, medium and low-end models

Embodiment Construction

[0024] figure 1 Shown is a specific embodiment of the special resistance muffler for the air intake of the vehicle air pump of the present invention, which includes a metal tube 1, the metal tube 1 is a round tube, and it is filled with a material rolled by a porous mesh material. Formed porous filler 2.

[0025] In this example, the porous mesh material is rolled into many rolls, generally at least one roll.

[0026] Moreover, the porous mesh material is a braided fabric woven from flat yarns (ie, flat filamentous materials), and the mesh number of the braided fabric is preferably 8-12 meshes per square centimeter. During implementation, first weave a cylindrical braid with flat yarn, then radially flatten the braided cylindrical braid to form a double-layer porous braided material, and then roll it into Porous filler 2, the porous filler 2 is inserted into the metal pipe 1 to form a muffler section.

[0027] The flat yarn is preferably selected from a material with strong...

Abstract

The invention discloses a reactive muffler special for inflation of an automotive inflation pump. The reactive muffler comprises a metal pipe which is filled with porous filler formed by rolling porous meshed materials. The reactive muffler is small in size, low in cost and convenient to mount. Different incident angles are formed through small holes formed by curling ribbon-like filament braided fabric, so that acoustic energy is divided, the acoustic wave propagation direction is changed, and the muffling effect is achieved through reflection, interference and counteraction phenomena of acoustic waves in the pipe.

Description

technical field [0001] The invention relates to a muffler, in particular to a special resistant muffler for the air intake of a vehicle air pump. Background technique [0002] With the development of the bus industry, the requirements for the number of seats and the distance between seats are getting higher and higher. In order to improve product competitiveness, vehicle manufacturers had to repeatedly compress the size of the rear cladding column, which resulted in the reduction of the diameter of the air pipe in the overhead air intake state of the engine that originally routed pipes in the cladding column, which could not meet the requirements of the engine intake. volume requirements. In order to solve this problem, the waist air intake state is adopted, which not only solves the problem of interior space, but also reduces the height of the noise outlet of the air intake system, which affects the quality of the whole vehicle to a certain extent. The air pump is closer ...
