Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, an exhaust system component support structure 100 according to an embodiment of the present invention will be described with reference to fig. 1 and 2.
The exhaust system component support structure 100 is used to support an exhaust system component (not shown) of an automotive internal combustion engine. Examples of the exhaust system component include an exhaust pipe and a muffler (muffler).
As shown in fig. 1, the exhaust system component support structure 100 includes a first pipe member 1 connected to a vehicle body 150, a second pipe member 2 connected to an exhaust system component, an elastic member 3 for mounting the first pipe member 1 and the second pipe member 2, and a third pipe member 4 for reinforcing the first pipe member 1.
The first pipe member 1 is made of metal and is configured in a hollow cylindrical shape. One end of the first pipe member 1 is welded to the vehicle body 150, and the other end is disposed below the vehicle body 150. The other end portion of the first pipe member 1 is formed in an L-shape, and includes a straight tube portion 11, a straight tube portion 12, and a bent portion 13. The straight tube portion 11 is arranged to extend downward from the vehicle body 150. The straight tube portion 12 is arranged to extend to the vehicle rear side (Y2 direction side) below the lower end portion of the straight tube portion 11. The bent portion 13 is provided between the straight tube portion 11 and the straight tube portion 12, and connects the straight tube portion 11 and the straight tube portion 12 with an angle of 90 degrees therebetween.
The second pipe member 2 is made of metal and is configured in a hollow cylindrical shape. The end of one end of the second pipe member 2 is connected to a bracket 160, and an exhaust system component is mounted on the bracket 160. That is, the second pipe member 2 is connected to the exhaust system component via the bracket 160. The second pipe member 2 is formed in a straight pipe shape with its axial direction parallel to the vehicle front-rear direction (the direction of Y1 and Y2).
The elastic member 3 is made of an elastic member such as rubber, and is configured to be elastically deformable. The elastic member 3 is provided between the vehicle body 150 and the exhaust system component, and has a function of suppressing transmission of vibration between the vehicle body 150 and the exhaust system component.
Specifically, the elastic member 3 is formed with two upper and lower pipe insertion holes (not shown). The first pipe member 1 is attached to the elastic member 3 by inserting the straight pipe portion 12 of the first pipe member 1 into the upper pipe member through hole from the vehicle front side (Y1 direction side). The second pipe member 2 is attached to the elastic member 3 by inserting the second pipe member 2 into the pipe through hole on the lower side from the vehicle rear side.
The third pipe element 4 is mounted on the first pipe element 1 as shown in fig. 2 for reinforcing the first pipe element 1. In fig. 2, the first pipe member 1 and the third pipe member 4 are shown in an enlarged manner, and the bent portion 13 of the first pipe member 1 and the portion in the vicinity thereof are extracted.
The third pipe member 4 is made of metal and is configured in a hollow cylindrical shape. For example, the cross-sectional dimensions (inner diameter, outer diameter, and wall thickness) of the third pipe member 4 may be set to be the same as those of the first pipe member 1. The third pipe 4 is formed in an L-shape, and has a straight pipe portion 41, a straight pipe portion 42, and a bent portion 43.
The straight tube portion 41 is shorter than the straight tube portion 11, and the straight tube portion 42 is shorter than the straight tube portion 12. The bent portion 43 is provided between the straight tube portion 41 and the straight tube portion 42, and connects the straight tube portion 41 and the straight tube portion 42 with an angle of 90 degrees therebetween. In addition, for example, the weight of the third pipe member 4 may be set smaller than the weight added by making the first pipe member 1 solid.
The third tube member 4 is arranged alongside the first tube member 1. Specifically, the third pipe member 4 is disposed adjacent to the first pipe member 1 in the vehicle width direction (X direction), and the third pipe member 4 overlaps the first pipe member 1 when viewed from the vehicle width direction.
The first pipe member 1 and the third pipe member 4 are connected by welding, and a weld bead WB is formed between the first pipe member 1 and the third pipe member 4. In more detail, the straight tube portion 11 and the straight tube portion 41 are joined by welding; the straight tube portion 12 and the straight tube portion 42 are joined by welding; the bent portion 13 and the bent portion 43 are joined by welding.
Has the advantages that:
in the present embodiment, as described above, the hollow third pipe member 4 is attached to the first pipe member 1, whereby the first pipe member 1 can be reinforced and the strength of the vehicle body side support portion can be improved, and since the third pipe member 4 is a hollow pipe member and the weight thereof is smaller than the weight increased by making the first pipe member 1 solid, the weight increase of the vehicle body side support portion (the support portion of the elastic member 3 provided in the vehicle body 150) can be suppressed.
That is, the structure in which the first pipe 1 is reinforced by the third pipe 4 can prevent the first pipe 1 from being deformed when a load due to vibration acts on the first pipe 1 while suppressing an increase in vehicle weight, as compared with the structure in which the first pipe 1 is made solid. In addition, in the case of the structure in which the first pipe member 1 is made solid, when the first pipe member 1 is welded to the body panel of the vehicle body 150, the body panel is likely to melt and fall off (easily damaged), and the structure according to the present embodiment can avoid such disadvantages.
