Description

Vehicle Exhaust Pipe Fixture

The present invention relates to a vehicle exhaust pipe fixing device, and to further enhance the vibration absorbing effect transmitted from the exhaust pipe, to further increase the vibration absorbing means separate from the vibration absorbing portion of the exhaust pipe, the vibration transmitted from the exhaust pipe The present invention relates to a vehicle exhaust pipe fixing device capable of sufficiently absorbing water.

Vibration that impairs the comfort of the vehicle is generated by the power generating device, the power transmission device, and an external force applied from the outside of the vehicle.

Efforts have been made to provide a vibration absorbing member or to improve the constitutive mechanism of the vibration generating part in order to eliminate the vibration generated from the above-mentioned vehicle body vibration generating factors.

In particular, since the engine unit, which is a power generating device, generates strong noise and vibration, the solution is one of important issues for realizing the superiority of the vehicle.

The engine unit includes an engine body, a lubrication device, a fuel device, a cooling device, an intake and exhaust device, a start, an ignition, a charging device, and the like.

The exhaust unit of the engine unit is used as a means for discharging the exhaust gas exploded in the cylinder into the atmosphere, and includes a muffler and a catalytic device to reduce noise caused by the exhaust gas and reduce harmful substances in the combustion gas. It also has a function to make.

The exhaust device includes an exhaust manifold and an exhaust pipe connected to each cylinder of the engine and is coupled to the vehicle body.

The exhaust pipe is coupled to the vehicle body through the vibration absorbing member so that the absorbing member can eliminate the vibration transmitted to the vehicle body.

4 is a cross-sectional view of an exhaust pipe fixing device showing an embodiment according to the prior art, where reference numeral 101 is a vehicle body and 103 is an exhaust pipe.

The exhaust pipe fixing device includes an absorbing member 107 coupled with a rod 105 coupled to one side of the exhaust pipe 103, and a rod 109 coupled to the vehicle body to fix the absorbing member 107.

The rod 109 forms a disk-shaped coupling portion at the end to increase the coupling force with the vehicle body.

Since the absorbing member 107 has self-elasticity, the absorbing member 107 can absorb vibration of the exhaust pipe 103, and in particular, effectively absorbs vibration in the vertical direction with the ground.

As described above, the fixing device of the conventional exhaust pipe includes an absorbing member to absorb the vibration transmitted from the exhaust pipe. However, since the absorbing member absorbs the vibration only by its own elastic force, the absorption of the vibration pipe is limited. Since the absorbing member is made of rubber, there is a problem in that the vibration absorbing power is significantly lowered when cured.

The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to solve the factors that hinder the pleasure of passengers in the vehicle by sufficiently absorbing vibration transmitted from the exhaust pipe. .

In order to realize the object of the present invention, in the vehicle exhaust pipe fixing device, the disk is horizontally coupled to one side of the rod coupled to the absorbing member, and is coupled to the vehicle body with an inner space capable of embedding the disk. It provides a configuration including a disk housing and a plurality of ball bearings mounted between the disk and the friction surface of the disk housing to absorb the micro vibrations transmitted from the exhaust pipe.

In order to absorb the strong vibration transmitted from the exhaust pipe, a rubber pad ring is provided on the inner circumferential surface of the disk housing where the outer circumferential surface of the disk strikes to absorb the shock applied by the disk.

Since the vibration absorbing means absorbs the vibration transmitted from the exhaust pipe again, the amount of vibration applied to the vehicle body can be remarkably reduced. When the exhaust pipe is fixed by using the floating disk member, the vibration can be eliminated through their slide friction. In addition, the lever pad ring can absorb the strong vibration of the exhaust pipe to significantly reduce the amount of vibration applied to the vehicle body.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a rear view of a vehicle showing an exhaust pipe to which the present invention can be applied, and reference numeral 1 shows an exhaust pipe to which the present invention can be applied.

The exhaust pipe 1 is a device for discharging the exhaust gas emitted from each cylinder of the engine to the atmosphere, one side is coupled to the exhaust manifold and the other side is open to the atmosphere side.

In addition, the exhaust pipe 1 can be equipped with a catalytic device for filtering contaminants in the exhaust gas, and is equipped with a muffler for reducing noise.

The exhaust pipe 1 has a rigidity capable of withstanding the weight and vibration of the exhaust pipe 1 by fixing a plurality of rods 3 at a predetermined distance to one side.

The rod 3 of the exhaust pipe 1 is equipped with an absorbing member 5 capable of absorbing the vibration of the exhaust pipe 1 so as to absorb the vibration of the exhaust pipe 1.

Since the absorbing member 5 has self-elasticity, the absorbing member 5 absorbs and blocks the vibration of the exhaust pipe 1, and is particularly effective for absorbing vibration in the vertical direction with respect to the ground.

The gist of the present invention is to absorb the vibration force which is not absorbed by the absorbent member 5 to the vehicle body again, and the preferred embodiment is as follows.

The disk housing 13 is fixed to the upper surface is coupled to the vehicle body, and forms an inner space for accommodating the disk 11 therein.

The disk housing 13 has a hole formed in the center of the lower side, so that the rod 9 of the disk 11 can move.

In the case where the ball bearing 15 is interposed between the disc housing 13 and the disc 11, a more effective action can be expected to absorb the small vibration in the vehicle width direction applied from the exhaust pipe 1.

In order to be able to absorb the microvibration in the vehicle width direction described above, the inner diameter of the disk housing 13 which is somewhat larger than the diameter of the disk 11 is formed.
