Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a support device for exhaust system parts for automobiles.

Conventionally, the exhaust system such as the muffler and exhaust pipe was supported on the underside of the vehicle body using an O-ring, as shown in Figure 1, and the exhaust system parts had a degree of freedom upward. Due to the vibration of the vehicle,
The exhaust system parts also vibrate up and down.

Therefore, due to the vibration, the bracket 1 on the vehicle body side and the bracket 3 on the exhaust system part (exhaust pipe in the illustration) 2 interfere with each other, producing a metallic sound, and the O-ring 4 also bounces, causing it to hit the bracket 1 on the vehicle body side. As a result, there were times when this part also made strange noises.

The present invention was made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a support device for supporting exhaust system parts using O-rings, which prevents hitting noises caused by running vibrations of the exhaust parts. This is the purpose.

The present invention will be described below with reference to illustrative embodiments.

11 is an exhaust pipe, 12 is a muffler, and brackets 13 and 14 for attachment to the underside of the vehicle body are fixed to each of them.

15.16 is a bracket fixed to the vehicle body side,
The bracket 13 is connected to the bracket 13 via an elastic O-ring 17.
．． 14 is suspended to support the exhaust pipe 11 and muffler 12.

A stopper rubber 18 is interposed between the bracket 13 on the exhaust pipe 11 side and the bracket 15 on the vehicle body side, and between the bracket 14 on the muffler 12 side and the bracket 16 on the vehicle body side, and has a screw groove 18a on the outer periphery. It is formed into a cylindrical shape, and its one end 18b is screwed into the vehicle body side bracket 15, 16, and the other end 18c is adapted to abut on the upper surface of the exhaust pipe 11 side bracket 13 and the muffler 12 side bracket 14.

In the above embodiment, one end 18 of the stopper rubber 18
b is attached to the vehicle body side bracket 15, 16, but the present invention is not limited to this. One end 18b of the stopper rubber 18 may be attached to the bracket 13 on the exhaust pipe 11 side and the bracket on the muffler 12 side, and the other end may be attached to the bracket 15 or 16 on the vehicle body side. may be brought into contact with the vehicle body side bracket 15, 16.

Further, the shape of the stopper rubber 18 is not limited to a cylindrical shape, and as shown in FIG. 5, the other end 18c that comes into contact with the bracket 13. The shape is not limited.

The reason why the stopper rubber 18 is made hollow is to lower the spring constant and absorb minute vibrations of the exhaust system through the stopper rubber 18.

According to the above embodiment, since the stopper rubber is of a screw-in type, it is easy to adjust even if the gap between the two brackets varies.

As described above, the present invention is an exhaust system component support device in which the exhaust system component side bracket and the vehicle body side bracket are connected by an elastic O-ring to support the exhaust system component on the underside of the vehicle body. One end of the stopper rubber is attached to either the exhaust system component side bracket or the vehicle body side bracket, and the other end of the stopper rubber is brought into contact with the other bracket, so that the exhaust system components cannot be moved above the exhaust system while driving. Since the degree of freedom is restricted and the vibration is suppressed, there will be no metallic noise caused by collisions between the brackets, or the O-ring will not sag, so there will be a difference between the sagging of the O-ring and the movement of the bracket, and the two will separate. It is possible to prevent abnormal noises caused by interference between the O-ring and the bracket due to contact between the O-ring and the bracket.

Therefore, it is possible not only to improve the durability of the exhaust system parts, but also to prevent the O-ring from falling off due to bounce.

Further, according to the present invention, the O-ring and the stopper rubber have the effect of suppressing vibrations in the exhaust system such as the exhaust pipe.
