Abstract
The utility model relates to a muffler used for vehicle, belonging to technology field of car accessories, aiming at providing good fluent performance and good result of noise elimination by improving the current muffler. The utility model comprises an outer cylinder with an air outlet and an air inlet on the two ends. The improved structure of the utility model is that a plurality of clapboards are discretely arranged in the outer cylinder and a vent is arranged between the outer cylinder and each clapboard respectively; the vents of the clapboards are staggered to form a roundabout discharge channel. The utility model gets rid of the serpentuator in the outer cylinder and adopts a plurality of clapboards discretely arranged in the outer cylinder to form a roundabout discharge channel by the stagger vents, therefore the section of the channel is exponentially increased compared to the serpentuator, and the meandrous performance is greatly improved compared to the multi cavity structure in the outer cylinder. The utility model is excellent in fluent performance, discharge resistance, meandrous performance and noise elimination result, therefore the utility model is a perfect substitute for the muffler.
Description
Technical field
The utility model relates to a kind of automobile-use noise silencer, belongs to the car accessories technical field.
Background technology
Noise silencer all is housed on the freeing pipe of motor car engine, is used for reducing and removing noise.Noise silencer has urceolus, and in urceolus or the snake-like tube row tracheae is set, or the upper and lower dislocation of inlet, outlet that is divided into the multi-cavity chamber and makes adjacent chamber is to form circuitous exhaust passage.In the two, the former effect of eliminating the noise is better, but because the less tortuosity of caliber is big, resistance of exhaust is bigger; The big complications in the cross section of latter exhaust passage are little, and unobstructed property is good, and the noise elimination effect is then relatively poor, thus the normal occupation modes that adopt two polyphones to install, though this measure can improve the noise elimination effect relatively, counter have bring exhaust resistance to reach the use disadvantage that increases noise silencer greatly.Though noise silencer is an additional function annex in the self-propelled vehicle, its mode of operation can so be necessary existing noise silencer is improved, make it overcome above-mentioned deficiency to operation and the urban environmental protection that has influence on driving engine.
Summary of the invention
Technical problem to be solved in the utility model provides the automobile-use noise silencer, and this noise silencer should have good unobstructed property and noise elimination function.
The alleged problem of the utility model realizes with following technical scheme:
A kind of automobile-use noise silencer has urceolus in the formation, there is inlet, outlet at the urceolus two ends, its improvement is, at interval dividing plate is set in described urceolus 1, leaves exhausr port between each dividing plate and the urceolus, the exhausr port mutual dislocation of adjacent separator forms circuitous exhaust passage.
Above-mentioned automobile-use noise silencer, described urceolus 1 is a cylinder, and described dividing plate 2 is isometrical plectane, and the excircle of each plectane links to each other with the urceolus coupling, and described exhausr port is the arcuate indentation P on the plectane, the arcuate indentation P on the adjacent plectane is upper and lower to shift to install.
Above-mentioned automobile-use noise silencer, described urceolus 1 is a cylinder, described dividing plate is plectane and is divided into large and small two groups, the excircle of big group plectane 2A links to each other with the urceolus coupling, its centre hole pk is an exhausr port, and the excircle of the plectane 2B of group is less than the urceolus internal diameter, and the annulus between itself and the urceolus is the exhausr port ph on the little plectane, large and small group of plectane interphase distribution is connected in aggregates with spacing sleeve 4 and is installed in the urceolus by overbolt 3.
Above-mentioned automobile-use noise silencer, the dividing plate that is provided with at interval in the described urceolus 1 is vertical with the tubular axis direction.
Above-mentioned automobile-use noise silencer, the inside diameter D of described urceolus 1 are 60mm～500mm, and tube length L is 200～900mm, and the distance between the adjacent separator is decided on the size of free air capacity.
The utility model has been cancelled the coil pipe in the outer cylinder body, at the urceolus internal face dividing plate is set at interval, and the exhausr port by mutual dislocation on the adjacent separator forms circuitous exhaust passage, this structure design relative coil pipe structure, and channel cross-sectional area increases exponentially; Relative multi-cavity cell structure in the urceolus, the full of twists and turns property of passage greatly improves, so the characteristic that existing unobstructed property is good, exhaust resistance is good has the circuitous property effective advantage of eliminating the noise well again simultaneously, reality is a kind of comparatively ideal noise silencer substitute products.
Description of drawings
Fig. 1 is a kind of example structure scheme drawing;
Fig. 2 is an A-A cutaway view among Fig. 1;
Another example structure scheme drawing of Fig. 3.
The specific embodiment
Consult accompanying drawing, urceolus 1 can be circle, ellipse, square or rectangle etc.Dividing plate can wait to be come out by vertical extent on the internal face by casting, but also split is welded on the urceolus, and the inside diameter D of urceolus 1 can be 200mm, and tube length L is 400mm.The thickness of slab of dividing plate is decided on plate face size etc.
Consult accompanying drawing 1,2, in the illustrated embodiment, urceolus 1 is a cylinder, and dividing plate 2 is isometrical plectane, and the excircle and the urceolus of each plectane are welded to connect, on the adjacent separator 2, the following arcuate indentation P that shifts to install forms circuitous exhaust passage.
Consult Fig. 3,, among this embodiment, urceolus 1 still is a cylinder, large and small group plectane 2A, 2B interphase distribution are connected in aggregatesly with a plurality of spacing sleeves 4 by two overbolts 3, be installed in the urceolus 1, the excircle of big group plectane 2A and the diameter of bore of urceolus 1 are complementary, only have very little assemblage gap, centre hole pk is an exhausr port, and the excircle of the plectane 2B of group is less than the urceolus internal orifice dimension, annulus between itself and the urceolus is exhausr port ph on the little plectane, forms the circuitous exhaust passage that dwindles amplification.
