Abstract
The invention relates to a bestriding-type vehicle exhaust muffler which comprises an exhaust pipe (1), a muffling pot (2) and a ternary catalyst assembly (4). A primary swelling muffler box (3) is additionally arranged between the exhaust pipe (1) and the muffling pot (2); an inner cavity of the primary swelling muffler box (3) is divided into a first cavity and a second cavity which are communicated by an aeration pipe; the exhaust pipe (1) penetrates into one end of the primary swelling muffler box (3), sequentially penetrates through the second cavity and the first cavity, penetrates out of the other end of the primary swelling muffler box (3) and is connected with one end of the ternary catalyst assembly (4) of which the other end is communicated with the first cavity; and the muffling pot (2) is communicated with the second cavity. The invention not only improves the output power of an engine, but also improves the muffling effect, and is readily assembled on a frame.
Description
Technical field
The present invention relates to the bestride type vehicle component, be meant a kind of exhaust silencer of bestride type vehicle concretely.
Background technique
Bestriding-type vehicle exhaust muffler mainly is made up of outlet pipe and silencing apparatus tube, and the silencing apparatus tube is connected the rear end of outlet pipe.On common striding type bestride type vehicle, after outlet pipe is drawn from the engine exhaust end usually from the vehicle frame side or the bottom surface behind car, extend and link to each other with the silencing apparatus tube, the silencing apparatus tube is generally cylindric and does longlyer.For sport car type bestride type vehicle, for the outputting power that makes motor more powerful, add the reason of vehicle frame moulding, the silencing apparatus tube is then done all shortlyer, and that the performance that will bring into play motor requires outlet side from the exhaust end of motor to the silencing apparatus tube to guarantee is certain for length.So, people wish that still sport car type bestride type vehicle can have a reasonable noise elimination effect when powerful outputting power is provided, how realize this point on the very compact vehicle frame of bestride type vehicle existing space, be industry problem anxious to be solved all the time.
Summary of the invention
In view of the problem of above existence, the purpose of this invention is to provide a kind of being convenient to and on vehicle frame, arrange, both improved engine output power, improved the Bestriding-type vehicle exhaust muffler of noise elimination effect again.
For achieving the above object, the invention provides a kind of Bestriding-type vehicle exhaust muffler, include outlet pipe, silencing pot and three-way catalyst assembly, between outlet pipe and silencing pot, add elementary expansion noise elimination box, the inner chamber of elementary expansion noise elimination box is divided into first chamber and second chamber by dividing plate, be communicated with breathing pipe between first chamber and second chamber, outlet pipe pierces into from an end of elementary expansion noise elimination box, pass successively behind second chamber and first chamber and to pass the back from the other end of elementary expansion noise elimination box and link to each other with an end of three-way catalyst assembly, the other end of three-way catalyst assembly is communicated with first chamber, and silencing pot is communicated with second chamber.
Further, elementary expansion noise elimination box is a flat, and elementary expansion noise elimination box is positioned at the motor below during assembling, and the upper surface of elementary expansion noise elimination box is connected with thermal baffle.The purpose that thermal baffle is set is exactly to prevent that the interior heat of waste pipe to motor bottom radiation, heating motor, makes engine temperature too high, so that influence the viscosity of motor inner engine oil.
The present invention is by installing elementary expansion noise elimination box additional, improved the noise elimination effect of whole silencing apparatus, and allow outlet pipe and silencing pot link to each other with elementary expansion noise elimination box by the above-mentioned circuitous or mode of turning back, not only do not allow outlet pipe shorten, outlet pipe has also obtained prolongation, thereby improves the outputting power of motor.Elementary expansion noise elimination box is installed in the below of motor during assembling, and such arrangement can not impact the structure of vehicle frame, arranges and install more convenient.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2 and shown in Figure 3, Bestriding-type vehicle exhaust muffler of the present invention has outlet pipe 1, silencing pot 2, elementary expansion noise elimination box 3 and three-way catalyst assembly 4, the inner chamber of elementary expansion noise elimination box 3 is divided between first chamber 31 and 32, the first chambeies 31, second chamber and second chamber 32 by dividing plate 8 and is communicated with by breathing pipe 5.Outlet pipe 1 pierces into from an end of elementary expansion noise elimination box 3, link to each other with an end of three-way catalyst assembly 4 after passing second chamber 32 successively and first chamber, the 31 back the other ends from elementary expansion noise elimination box 3 passing, the other end of three-way catalyst assembly 4 is communicated with first chamber 31, and silencing pot 2 is communicated with second chamber 32.
First chamber is provided with dunnage 6 for 31 li, and an end of breathing pipe 5 passes and is fixed on the dunnage 6, is distributed with many vents 61 on the dunnage 6.
Elementary expansion noise elimination box 3 is a flat, is assembled by last lower casing butt joint, and the upper surface of elementary expansion noise elimination box 3 is connected with thermal baffle 7.Referring to Fig. 4, elementary expansion noise elimination box 3 is positioned at motor 10 belows during assembling, and thermal baffle 7 is separated motor 10 and elementary expansion noise elimination box 3, and the high-temperature gas of avoiding 3 li in elementary expansion noise elimination box impacts the machine oil of 10 li in motor.
Elementary expansion noise elimination box 3 is provided with the drain the oil via hole 9 relative with motor drain oil position, and the via hole 9 of draining the oil is made of a pipe that runs through elementary expansion noise elimination box 3 upper and lower surfaces, does not dismantle silencing apparatus when being convenient to engine maintenance like this and just can directly put machine oil.
The shape size of silencing pot 2 remains unchanged among the present invention, by installing elementary expansion noise elimination box 3 additional, improved the noise elimination effect of whole silencing apparatus, and allow outlet pipe 1 link to each other with elementary expansion noise elimination box 3 in a manner described with silencing pot 2, not only do not allow outlet pipe 1 shorten, also obtain prolongation, thereby improved the outputting power of motor.Because elementary expansion noise elimination box 3 is mounted in the below of motor, such arrangement can not impact the structure of vehicle frame, layout, easy for installation.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
