Abstract
The invention discloses a vehicle muffler. The vehicle muffler comprises a cylinder body, an air inlet pipe and an air exhaust pipe which are in mutual fit. A drain hole is formed at the bottommost point of the cylinder body, a rivet is fixedly inserted in the drain hole, and a through hole penetrates through the middle of the rivet in the radial direction of the rivet. The cylinder body comprises an inner casing and an outer casing, wherein the inner casing and the outer casing are sleeved on the cylinder body from inside to outside, cling to each other tightly and are fixed in a riveting mode through the rivet. During work, accumulated water in the cylinder body is drained through the through hole and can be drained thoroughly and effectively as the rivet is located at the bottommost point of the cylinder body. Meanwhile, the inner casing and the outer casing are fixed in a riveting mode through the rivet so that the inner casing and the outer casing are ensured to cling to each other tightly and not to have water immersion, and further the corrosion resistance and the work reliability of the vehicle muffler are remarkably improved. In addition, the double-layer casing structure improves the muffling performance of the vehicle muffler.
Description
Technical field
The present invention relates to motor vehicle fittings technical field, particularly a kind of silencer for motor vehicle.
Background technique
Silencing apparatus is one of critical function assembly of Motor Vehicle, and improving constantly along with user demand, the service behaviour of silencing apparatus also gets more and more people's extensive concerning day by day.
In current existing silencing apparatus assembly structure, for avoiding cylindrical shell corrosion and perforation, interpolation pipe draining or individual layer cylindrical shell minimum point punching draining two kinds of modes usually can be adopted to get rid of the ponding in cylindrical shell.Under normal circumstances, cylindrical shell adopts during interpolation pipe draining and requires that interpolation pipe is arranged in inner barrel highpressure chamber, but highpressure chamber might not be cylindrical shell ponding bosom, and causing cannot thoroughly by ponding emptying; According to the mode that individual layer cylindrical shell punches in minimum point, although can emptying ponding, there is the problem of individual layer cylindrical shell acoustic attenuation performance difference, easily produce cylindrical shell radiated noise excessive problem.
Therefore, a kind of ponding how is provided to get rid of in time thoroughly and the good silencing apparatus of acoustic attenuation performance is those skilled in the art needs the important technological problems that solves at present.
Summary of the invention
The object of this invention is to provide a kind of silencer for motor vehicle, the ponding of this silencer for motor vehicle is got rid of comparatively in time thoroughly, and its acoustic attenuation performance is better.
For solving the problems of the technologies described above, the invention provides a kind of silencer for motor vehicle, comprise the cylindrical shell, suction tude and the outlet pipe that cooperatively interact, the minimum point place, bottom of described cylindrical shell is provided with weep hole, in described weep hole, plug-in mounting is fixed with rivet, and the middle part of described rivet is radially run through through hole;
Described cylindrical shell comprises from-inner-to-outer suit adaptation and the inner housing fitted tightly and frame, and described inner housing and described frame are fixed by described rivet.
Preferably, described cylindrical shell is for striking out shaped piece.
Preferably, described rivet is stainless steel product.
Relative above-mentioned background technology, silencer for motor vehicle provided by the present invention, comprises the cylindrical shell, suction tude and the outlet pipe that cooperatively interact, and the minimum point place, bottom of described cylindrical shell is provided with weep hole, in described weep hole, plug-in mounting is fixed with rivet, and the middle part of described rivet is radially run through through hole; Described cylindrical shell comprises from-inner-to-outer suit adaptation and the inner housing fitted tightly and frame, and described inner housing and described frame are fixed by described rivet.In equipment working procedure, the ponding in cylindrical shell is discharged via described through hole, because described rivet is positioned at the bottom minimum point of cylindrical shell, its ponding is discharged comparatively thoroughly effectively; Simultaneously, inner housing and frame are riveted fixing by described rivet, can ensure that inner housing and frame fit tightly and avoid inner housing and frame to soak, and then prevent immersion corrosion housing, and prevent the silencing apparatus producing housing deformation of cylindrical because of moisture high-temperature evaporation after double-layer shell structure immersion and cause to lose efficacy or abnormal sound phenomenon, thus significantly improve corrosion resistance and the functional reliability of described silencer for motor vehicle, in addition, double-layer shell structure also makes the acoustic attenuation performance of described silencer for motor vehicle be able to corresponding raising.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The assembly structure worm's eye view of the silencer for motor vehicle that Fig. 1 provides for a kind of embodiment of the present invention;
Fig. 2 is the structure side view of Fig. 1;
Fig. 3 is the partial structurtes enlarged diagram of part A in Fig. 2.
Embodiment
Core of the present invention is to provide a kind of silencer for motor vehicle, and the ponding of this silencer for motor vehicle is got rid of comparatively in time thoroughly, and its acoustic attenuation performance is better.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the assembly structure worm's eye view of the silencer for motor vehicle that Fig. 1 provides for a kind of embodiment of the present invention; Fig. 2 is the structure side view of Fig. 1; Fig. 3 is the partial structurtes enlarged diagram of part A in Fig. 2.
In a specific embodiment, silencer for motor vehicle provided by the present invention, comprise the cylindrical shell 11, suction tude 12 and the outlet pipe 13 that cooperatively interact, the minimum point place, bottom of cylindrical shell 11 is provided with weep hole 113, in weep hole 113, plug-in mounting is fixed with rivet 14, and the middle part of rivet 14 is radially run through through hole 141; Cylindrical shell 11 comprises from-inner-to-outer suit adaptation and the inner housing 111 fitted tightly and frame 112, and inner housing 111 and frame 112 are riveted fixing by rivet 14.In equipment working procedure, the ponding in cylindrical shell 11 is discharged via through hole 141, because rivet 14 is positioned at the bottom minimum point of cylindrical shell 11, its ponding is discharged comparatively thoroughly effectively; Simultaneously, by rivet 14, inner housing 111 and frame 112 are riveted fixing, can ensure that inner housing 111 and frame 112 fit tightly and avoid inner housing 111 and frame 112 to soak, and then prevent immersion corrosion housing, and prevent the silencing apparatus producing housing deformation of cylindrical because of moisture high-temperature evaporation after double-layer shell structure immersion and cause to lose efficacy or abnormal sound phenomenon, thus significantly improve corrosion resistance and the functional reliability of silencer for motor vehicle, in addition, double-layer shell structure also makes the acoustic attenuation performance of silencer for motor vehicle be able to corresponding raising.
