Thus, first dividing plate 54 and second partition 57 combine first bottom 66 and second bottom 75, have therefore improved the rigidity of first bottom 66 and second bottom 75.
Similarly, the plat part 137 of second partition 57 be provided with to the outstanding stiffening rib 138 that is shaped of direction of its Surface Vertical, therefore improved the rigidity of plat part 137 by this stiffening rib 138.By improving the rigidity of plat part 137, can reduce plat part 137 because of contacting situation about vibrating with discharge gas.And,, also can reduce the sound that sends to air because of the vibration transfer of plat part 137 by reducing the vibration of plat part 137.
And side wall portion 69 is a cylinder in embodiment 1.Side wall portion 69 forms cylindric, and easy shaping side wall portion 69 therefore becomes.
In addition, first bottom 66 and second bottom 75 are circular in embodiment 1.Because first bottom 66 and second bottom 75 be circular, so easily side wall portion 69 is formed cylindricly, and improve the rigidity of container 132 easily.Consequently, help sound-inhibiting, vibration.
In addition, side wall portion 69 also can be a cylindroid.And first bottom 66 and second bottom 75 also can be oval.
And then, catalyzer pipe arrangement 56 is held in the through hole 78 of second partition 57, first pipe arrangement 58 is held in the through hole 81,83 of second partition 57, second partition 57 edges is penetrated and are assembled in the inside of container 132 from second direction of bottom 75 towards first bottom 66.
That is, second partition 57 along with first bottom 66 and second bottom 75 roughly the direction of quadrature be inserted into the inside of container 132.On the other hand, catalyzer pipe arrangement 56 on the direction of first bottom 66 and second bottom 75 through the through hole 78 of second partition 57.And first pipe arrangement 58 is at the through hole 81,83 that runs through second partition 57 on the direction of first bottom 66 and second bottom 75.
Therefore, second partition 57 is inserted into direction and the catalyzer pipe arrangement 56 and first pipe arrangement 58 in the container 132, and to run through the direction of through hole 78,81,83 of second partition 57 different, therefore, when after making the catalyzer pipe arrangement 56 and first pipe arrangement 58 run through second partition 57 in advance, inserting second partition 57 in the container 132 again, the catalyzer pipe arrangement 56 and first pipe arrangement 58 are difficult for skew with respect to the position of second partition 57, and second partition 57 and catalyzer pipe arrangement 56 and first pipe arrangement 58 become easy with respect to the assembling of container 132.
In addition, for first bottom 66 and second bottom 75, in embodiment 1 be with the bottom of drum type spare 52 as first bottom 66 and with the bottom of cover 59 as second bottom 75, yet also can with the bottom of drum type spare 52 as second bottom and with the bottom of cover 59 as first bottom.With the bottom of cover 59 as first bottom, the situation of bottom as second bottom with drum type spare 52 under, second partition 57 penetrates directions in the above-mentioned container 132 for from the direction of first bottom towards second bottom.With next figure the internal structure of silencing apparatus 50 is described.
In Fig. 4, symbol 47 is the horizontal line that passes the center 48 of silencing apparatus 50, and arrow FR shows the place ahead of motor bike (symbol 10 of Fig. 1).Dividing plate 100 is made of first dividing plate 54 and second partition 57, the internal surface 97 that one end 95 of described first dividing plate 54 and the other end 96 extend to side wall portion 69, one end 98 of described second partition 57 extends to this first dividing plate 54, and the other end 99 then extends to the internal surface 97 of side wall portion 69.
The inside of container 132 is divided into second expansion chamber 102 in first expansion chamber 101, first expansion chamber, 101 downstream sides of upstream side and the 3rd expansion chamber 103 in downstream side by first dividing plate 54 and second partition 57, therefore can reduces exhaust sound effectively.
And then an end 98 of an end 95 of first dividing plate 54 and the other end 96, second partition 57 and the other end 99 bend and form, and have therefore guaranteed the rigidity as dividing plate.
In addition, one end 98 of one end 95 of first dividing plate 54, the other end 96 of first dividing plate 54, second partition 57 and the other end 99 of second partition 57 respectively with slightly against mode be connected to the internal surface 97 of side wall portion 69 and the plat part 135 of first dividing plate 54, therefore try assembling easily.And, help reducing vibration.And then, owing to welded securely, therefore can absorb the thermal distortion of first dividing plate 54, second partition 57 and side wall portion 69 effectively.
And, being located at the upstream side opening 67 of side wall portion 69, be connected with outlet pipe 46 via catalyzer pipe arrangement 56.And catalyzer 106 is located in the catalyzer pipe arrangement 56 along first dividing plate, 54 ground.Have again, be provided with the through hole 105 that first expansion chamber 101 and second expansion chamber 102 are communicated with at second partition 57.Second pipe arrangement 104 of first dividing plate 54 is for being communicated with the outlet pipe of second expansion chamber 102 and the 3rd expansion chamber 103.Next, describe discharging gas flow.
When from the discharge gas of motor from the outlet pipe shown in the double dot dash line 46 shown in arrow (1) in the inflow catalyst pipe arrangement 56 after, discharge gas passes through the catalyzer 106 and first pipe arrangement 58 in the catalyzer pipe arrangement 56 shown in arrow (2), flow into first expansion chamber 101, acoustic energy reduces.
The discharge gas of discharging from the outlet 79 of first pipe arrangement 58 collides the internal surface 97 of side wall portion 69 and flows shown in arrow (3), yet because side wall portion 69 forms cylindricly, so side wall portion 69 has higher rigidity.Therefore, can reduce because of discharging the vibration that gas collisions side wall portion 69 produces.
Next, discharge gas and pass through through hole 105 shown in arrow (4), and flow into second expansion chamber 102 shown in arrow (5), acoustic energy further reduces.
Next, discharge gas shown in arrow (6) by second pipe arrangement 104 and flow into the 3rd expansion chamber 103, acoustic energy further reduces.Discharge gas internal surface 97 along side wall portion 69 cylindraceous shown in arrow (7) of discharging from the outlet 121 of second pipe arrangement 104 flows, and it is smooth and easy therefore to discharge gas flow.
At last, discharging gas discharges from tail pipe 53 shown in arrow (8).Like this and since at container 132 internal consumptions discharge the acoustic energy of gas, therefore brought into play sound deadening.
In addition, the inlet 77 of catalyzer pipe arrangement 56 is fixedly welded on side wall portion 69, yet because the intermediate portion 107 of catalyzer pipe arrangement 56 is not fixedly welded on the through hole 78 of second partition 57, so catalyzer pipe arrangement 56 can be flexible with respect to second partition 57 heat.Simultaneously, the intermediate portion 108 of first pipe arrangement 58 is not fixedly welded on the through hole (symbol 81 of Fig. 3) of second partition 57 yet.And the intermediate portion 109 of first pipe arrangement 58 is not fixedly welded on the through hole 83 of second partition 57 yet.Therefore, first pipe arrangement 58 can be flexible with respect to second partition 57 heat.
In silencing apparatus 50, the center 142 of the joint 139 of tail pipe 53, the joint 141 of catalyzer pipe arrangement 56, catalyzer 106 all is disposed at the below with respect to the horizontal line 47 at the center 48 of passing silencing apparatus 50, therefore can realize the centre of gravityization of silencing apparatus 50.Next, the structure to container 132 describes.
As shown in Figure 5, drum type spare 52 extends the parts that form for side wall portion 69 integratedly from the outer rim of first bottom 66.Because side wall portion 69 extends integratedly from the outer rim of first bottom 66, therefore can reduce the components number of silencing apparatus 50.
And the outer rim in second bottom 75 is provided with integratedly along second side wall portion 76 cylindraceous that extends in the opposite direction with the side of first bottom 66, and the sidewall 134 that side wall portion 69 is possessed combines with second sidewall 133 that this second side wall portion 76 possesses.Second sidewall 133 of second side wall portion 76 and sidewall 134 seams of side wall portion 69 are welded, therefore can form the container 132 of silencing apparatus 50 with simple structure.The connecting part that the seam weldering obtains is a silencing apparatus protuberance 124.
In addition, symbol 122 is the consistent center line of axle center with trailing wheel (symbol 23 of Fig. 2), and is the horizontal line at the center of the center of first bottom 66 of passing container 132 and second bottom 75.
The associated methods of connecting part is the seam weldering in embodiment 1, yet also can use roll riveting (ロ one Le か め) to replace.Roll riveting is to instigate side wall portion 69 to extend to the outside (left side the figure) of container 132 from second side wall portion 76, and should be affixed on second side wall portion 76 by extended part volume, and compresses to improve bubble-tight joint method with roller.
And, owing to utilize first dividing plate 54 and second partition (symbol 57 of Fig. 3) to combine first bottom 66 and second bottom 75, therefore discharge gas when flowing in the container 132 of silencing apparatus 50, can suppress first bottom 66 that causes by this discharge gas and the vibration of second bottom 75 effectively.
And catalyzer pipe arrangement 56 disposes with the direction along first bottom 66 and second bottom 75 in the inside of container 132, and is configured to be applied in the through hole (symbol 78 of Fig. 3) that second partition is provided with.And first pipe arrangement 58 disposes with the direction along first bottom 66 and second bottom 75 in the inside of container 132, and is configured to be applied in the through hole ( symbol 81,83 of Fig. 3) that second partition is provided with.Therefore, even do not rely on the size of expansion chamber, also can establish outlet pipe longer.
In addition, especially, catalyzer pipe arrangement 56 is configured near second bottom 75 that is arranged in overall width direction (left and right directions of figure) inboard (left side), and the temperature by the overall width direction outside (right side) of catalyzer 106 is descended easily.Next, the position relation to silencing apparatus and trailing wheel describes.
In Fig. 6, (a) figure is a comparative example, is the trailing wheel of motor bike flatly to be cut open and the sectional view that obtains.The outlet pipe 202 of silencing apparatus 200 is connected in first bottom 201 that is configured in front end, tail pipe 206 as the part of outlet pipe is connected in second bottom 205 that is configured in the rear end, and possesses side wall portion 204 cylindraceous between first bottom 201 and second bottom 205.
Therefore, with respect to trailing wheel 203 gap spaced apart, and owing to will guarantee the capacity of silencing apparatus, so the overhang of the overall width direction of silencing apparatus 200 increases.Symbol 207 is the center line of the axletree 208 of trailing wheel 203.
(b) figure is embodiment, the rear end of combination swing part (symbol 22 of Fig. 2) is located in trailing wheel 23 rotations freely, this combination swing part is by motor (symbol 35 of Fig. 2) and swing arm 111 integrated formation that go out from the rear extension of this motor, in addition, silencing apparatus 50 supports fagging (symbol 51 of Fig. 2) via silencing apparatus and is supported on motor, and silencing apparatus 50 is connected with outlet pipe 46.That is, the combination swing part has the mechanism that silencing apparatus 50 and trailing wheel 23 are swung integratedly.
In addition, center line 122 is, pass trailing wheel 23 axletree 112 the center and pass the center of first bottom 66 of container 132 and the line at the center of second bottom 75.
In silencing apparatus 50, because outlet pipe 46 is connected in side wall portion 69, therefore compare with the situation of second bottom with outlet pipe being connected in first bottom, the silencing apparatus 50 that the interval between first bottom 66 and second bottom 75 is narrowed down can be provided.Therefore, compare with (a) figure, the size of stretching out of the overall width direction of silencing apparatus 50 (with the direction of first bottom, 66 quadratures) has reduced length L 1.
And, because silencing apparatus 50 does not relatively move with trailing wheel 23, therefore the part (for example the silencing apparatus protuberance 124) of silencing apparatus 50 can be accommodated in trailing wheel recess 119.Because silencing apparatus protuberance 124 is incorporated in trailing wheel recess 119, therefore be difficult for observing silencing apparatus protuberance 124 from the outside.Therefore, improved the aesthetic appearance of motor bike (symbol 10 of Fig. 1).
Have again, silencing apparatus 50 possesses silencing apparatus recess 127 in the radial direction inboard of silencing apparatus protuberance 124, this silencing apparatus recess 127 is recessed to the width direction outside (right side among the figure) of wheel rim 116 in the mode in the face of car shaft hub 114, so can make silencing apparatus 50 near trailing wheel 23 sides.Therefore, can provide the motor bike that can suppress overall width.
In embodiment 1, the side wall portion of the container of silencing apparatus is formed cylindric, yet the shape of side wall portion also can be a tubular oval, other arbitrary shapes.Among the embodiment 2 below the example that side wall portion is formed oval tubular is described.
