Description
Technical field
The present invention relates to automotive silencing field, specifically: two-door window shape baffle plate for silencing pot assembly.
Background technique
baffle plate for silencing pot assembly, as the significant components of automobile silencing, existing structure is mainly comprised of silencing pot and end cap, and wherein, silencing pot is provided with the circle of evenly arranging and crosses sound hole, and end cap is slab construction.Above-mentioned hush pipe is used in after the car of Alto, can attenuating noise, and when the original output noise of motor is 95 decibels, after the noise reduction after silencing pot end-cap assembly is processed, 73.58 decibels of its outputs, its noise is still larger.
Summary of the invention
Technical problem to be solved by this invention is that the two-door window shape baffle plate for silencing pot assembly that a kind of noise reduction value is large is set.
The present invention addresses the above problem adopted technological scheme: two-door window shape baffle plate for silencing pot assembly, comprise silencing pot A and silencing pot B that two axial lines is parallel, comprise dividing plate A parallel to each other and dividing plate B, silencing pot A flattens open and flat of rear rectangular silencing pot, open and flat of silencing pot is provided with several two-door window openings, two-door window opening comprises the sound hole of crossing of the rectangle that is arranged on open and flat of silencing pot, cross sound hole and be provided with crossbeam, the axis of crossbeam overlaps with the line of crossing sound hole relative edge mid point, crossbeam both sides are connected with wing plate A and wing plate B, crossbeam is divided into homalographic and two symmetrical through holes by crossing sound hole, between open and flat of wing plate A and silencing pot, form acute angle A, between open and flat of wing plate B and silencing pot, form acute angle B, the area of wing plate A equals the sound hole region area excessively in crossbeam left side, the area of wing plate B equals the sound hole region area excessively on crossbeam right side, silencing pot A external diameter is arranged with
