Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] see figure 1 , a muffler for a motor vehicle, including a muffler housing 1 with two ends unblocked, two muffler discs 2 are fixedly arranged in the muffler housing, and several muffler pipes 3 are arranged between the two muffler discs. All have through-hole 4 on the muffler disc, one end of the muffler pipe is connected with the through hole on one of the muffler discs, and the other end communicates with the through hole on the other muffler disc, the number of through holes 4 on each muffler disc 2 is the same as The number of silencer pipes corresponds; the through hole 4 provided on the silencer disc is a tapered hole.

[0013] A plurality of ventilation holes 5 communicating with the inside of the sound-absorbing pipe are provided in the radial direction of the sound-absorbing pipe, and a second group of through-holes 6 are also ...

Abstract

The invention relates to the technical field of silencers, in particular to a motor vehicle silencer. The motor vehicle silencer comprises a silencing shell of which the two ends are unblocked, wherein two silencing disks are fixedly arranged in the silencing shell; a plurality of silencing tubes are arranged between the two silencing disks; the two silencing disks are provided with through holes; one end of each silencing tube is communicated with the through hole in one of the silencing disks, and the other end of each silencing tube is communicated with the through hole in the other silencing disk. Air current flows into the silencing shell, enters the silencing tubes through the through holes in the silencing disks for silencing, is exhausted from the other ends of the silencing tubes, and is exhausted from the through hole in the other silencing disk, so that the air current can be silenced; the plurality of silencing tubes are arranged, so that silencing can be performed efficiently, and a great progress is made in comparison to the conventional silencer. The motor vehicle silencer is simple in structure and is reasonable in design, and the air current can be silenced efficiently.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a muffler for motor vehicles. Background technique [0002] Gasoline generators are generally equipped with mufflers to reduce noise. The structural design of the muffler currently on the market is unreasonable, especially for the noise reduction effect of the unit is not obvious. Contents of the invention [0003] In view of the above technical problems, the present invention provides a muffler for motor vehicles with simple structure and reasonable design, which can effectively silence the airflow. [0004] Realize the technical scheme of the present invention as follows: [0005] A muffler for a motor vehicle includes a muffler housing with two ends unblocked, two muffler discs are fixedly arranged in the muffler housing, several muffler tubes are arranged between the two muffler discs, and the two muffler discs are A through hole is provided, and one end of the muffler ...
