Abstract
The utility model discloses a mounting structure of a catalytic muffler for automobiles, comprising a first muffler fixing support (1) and a second muffler fixing support (7) which are arranged oppositely. The first muffler fixing support (1) is connected with an automobile frame, the second muffler fixing support (7) is connected with a muffler body, a sleeve (5) penetrates through the first muffler fixing support (1) and the second muffler fixing support (7) and is fixed via a self-locking nut (2), a first rubber cushion is disposed between the first muffler fixing support (1) and the second muffler fixing support (7), a second rubber cushion (4) is arranged between the self-locking nut (2) and the first muffler fixing support (1), and a gasket (3) is disposed between the self-locking nut (2) and the second rubber cushion (4). The mounting structure of the catalytic muffler for automobiles reduces damage to ceramic catalysts due to violent movement of the automobiles, prolongs service lives of the ceramic catalysts, and increases comprehensive performances of the ceramic catalysts.
Description
Technical field
The utility model relates to the mounting structure of a kind of automobile with catalytic muffler, especially relates to a kind of elastic mounting device that is used for state's four catalytic mufflers.
Background technology
Along with social development and scientific progress, automobile pollution is more and more, to the also constantly increase of influence of environment.Various countries improve constantly automobile emission regulation for the protection environment, and China has also formulated GB17691-2005 " automobile-used compression-ignited, gaseous fuel controlled-ignition engine and automobile exhaust pollutant discharge limit value and method of measurement (Chinese III, IV, V stage) " according to national conditions.According to the regulation of GB 17691-2005, China carried out IV stage Abgasgesetz since on January 1st, 2010.
For satisfying state's four Abgasgesetzs, two technology paths are arranged at present: the one, shift to an earlier date to reduce particulate matter by injection system optimization and injection timing earlier, re-use SCR (selective catalytic reduction) and reduce the NOX discharging that produces because of burning optimization; The 2nd, EGR (engine exhaust recirculation)+DPF (grain catcher) route, promptly reduce the composition of NOX in the discharging earlier by exhaust gas recycle, capture the particulate matter that slightly increases because of use EGR with grain catcher again, thereby reach the effect that reduces NOX and PM simultaneously.Since adopt SCR have good economy performance, to fuel oil less demanding (insensitive) and be easier to arrive state's five emission requests to sulphur, and become domestic main flow.SCR state four noise silencers not only play the effect of noise elimination noise reduction, also the catalytic carrier purifying exhaust gas must be installed, to satisfy emission request.Yet what present catalytic carrier mainly adopted is ceramic monolith, and this kind ceramic monolith owing to the high vibration of automobile, makes in-to-in ceramic catalytic device core destroy easily, thereby influences the Combination property of automobile in the process of using.
The utility model content
Technical problem to be solved in the utility model is to provide the mounting structure of a kind of automobile with catalytic muffler at problems of the prior art, its objective is that shock absorption device reduces because the destruction that the strenuous exercise of automobile brings for the ceramic catalytic device by being provided with, prolong the service life of ceramic catalytic device, improve its Combination property.
To be this kind automobile comprise the first noise silencer fixed support and the second noise silencer fixed support that is oppositely arranged with the mounting structure of catalytic muffler to the technical solution of the utility model, the described first noise silencer fixed support connects to ground, the second noise silencer fixed support is connected with muffler body, sleeve runs through the first noise silencer fixed support and the second noise silencer fixed support, and fix by self lock nut, be provided with shock absorption device between the described first noise silencer fixed support and the second noise silencer fixed support.
Described shock absorption device is for to be provided with first rubber mount at the circumference place of sleeve.
Be provided with second rubber mount between the described self lock nut and the first noise silencer fixed support, described second rubber mount is positioned at the circumference of sleeve.
Be provided with pad between the described self lock nut and second rubber mount.
A kind of automobile with said structure has the following advantages with the mounting structure of catalytic muffler:
1, this kind automobile mounting structure of catalytic muffler, when being in place, first rubber mount and second rubber mount itself also have the ability of elastic deformation, when noise silencer down moves, distortion produces cushioning effect thereby second rubber mount can produce elastic compression, in like manner during the noise silencer upward movement, first rubber mount is had an effect.When the noise silencer wigwag motion, because second rubber mount itself has certain elongation in the support bracket fastened connecting bore of first noise silencer, thus also can play a cushioning effect, thus the Combination property of catalytic muffler improved.
2, this kind automobile is simple in structure with the mounting structure of catalytic muffler, be easy to realize, and the effect excellence, have good value of service.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
In Fig. 1,1: the first noise silencer fixed support; 2: self lock nut; 3: pad; 4: the second rubber mounts; 5: sleeve; 6: the first rubber mounts; 7: the second noise silencer fixed supports. 8, tape welding connects the double-screw bolt band.
The specific embodiment
Structure shown in Figure 1 is the structural representation of automobile with the mounting structure of catalytic muffler, this kind automobile comprises the first noise silencer fixed support 1 and the second noise silencer fixed support 7 that is oppositely arranged with the mounting structure of catalytic muffler, the first noise silencer fixed support 1 connects to ground, the second noise silencer fixed support 7 is connected with muffler body, sleeve 5 runs through the first noise silencer fixed support 1 and the second noise silencer fixed support 7, and it is fixing by self lock nut 2, be provided with first rubber mount 6 between the first noise silencer fixed support 1 and the second noise silencer fixed support 7, be provided with second rubber mount 4 between the self lock nut 2 and the first noise silencer fixed support 1, second rubber mount 4 is positioned at the circumference of sleeve 5, is provided with pad 3 between the self lock nut 2 and second rubber mount 4.
Concrete installation process is: self lock nut 2 is down twisted, elastic deformations take place in first rubber mount 6 and second rubber mount 4, when the position of pad 3 fall sleeve 5 above the time because sleeve 5 is rigid bodies, self lock nut 2 can't down be twisted again, and be tight condition this moment.First rubber mount 6 and second rubber mount 4 itself also have the ability of elastic deformation when being in place, and when noise silencer down moved, distortion produced cushioning effect thereby second rubber mount 4 can produce elastic compression.In like manner, during the noise silencer upward movement, first rubber mount 6 is had an effect, thereby plays the effect of damping.
When the noise silencer wigwag motion,, also can play a cushioning effect because second rubber mount 4 itself has certain elongation in the connecting bore of the first noise silencer fixed support 1.
