Definitions
- the invention relates to an end pipe for an exhaust pipe of an exhaust system Motor vehicle according to the preamble of claim 1.
- an exhaust tailpipe which consists of an inner shell and an outer shell is composed.
- the connection inner shell on the Outer shell takes place at the mouth edge, in which air inlet openings are provided.
- the rear end facing away from the mouth edge is the inner shell with the Outer shell tightly connected.
- the object of the invention is an end pipe for an exhaust pipe To create an exhaust system that ensures improved heat and air dissipation is.
- the tailpipe is double-walled with an outer and inner shell executed, which are arranged at a distance from each other and between them Have an air gap.
- the inner shell is attached to the outer shell preferably at the mouth of the tailpipe. Another attachment is too conceivable.
- the end pipe is detachably connectable to the free end of the exhaust pipe, for what Screws are used that cause jamming with the exhaust pipe.
- Openings are provided in the inner shell, which allow the water to be washed around inserted exhaust pipe with head wind should cause the outer shell does not get too hot, and nearby plastic parts do not get radiated by heat or the chrome-plated outer shell is not damaged by the occurring heat is destroyed.
- the air flowing in between the two shell parts can be targeted arranged slot-like openings in the mouth of the tailpipe to the outside are derived, due to the prevailing in the mouth area A so-called jet effect is achieved.
- the between the Air flowing in from both shells is literally sucked out, creating a maximum Air flow and thus optimal heat dissipation and temperature reduction on Exhaust pipe is achieved.
- the openings in the area of the mouth edge can only between the Connection welds of the two shells are formed in a small Gap distance from the edge of the inner shell to the mouth edge of the outer shell will be produced.
- the inner shell there are longitudinal and transverse beads that protrude inwards provided on which the tail pipe is supported so that no continuous flat Attachment to the inner shell through the exhaust pipe.
- the beads Preferably two are with Spacing between the beads, the breakthroughs between them have arranged in the inner shell.
- a tail pipe 2 attached, which consists of an inner shell 3 and an outer shell 4, the preferably has a chrome plating.
- the inner shell 3 is spaced from the outer shell 4, such that forms a continuous air gap 5 all around. At the mouth edge 6 of the outer shell 4, the inner shell 3 is fastened, otherwise it is exposed in the outer shell 4 held. '
- the inner shell 3 there are at least one in the upper and one in the lower section Opening 7, 8 or a window for dissipating heat into the air gap 5 intended.
- the inner shell 3 with beads 10, 11 and 12, 12a provided with the exhaust pipe 1 their curvature are trimmed.
- the beads 10 and 12 are circumferential and the beads 12, 12a are arranged longitudinally to the exhaust pipe. They preferably delimit the openings 7 and 8 in the inner shell.
- the inner shell 3 butts against the mouth edge 6 of the outer shell and is connected to it via several welds. Between the welds louvers are formed, through which the air flowing in the direction of arrow 4, during the Driving of the vehicle flows against the direction of travel F.
- louvers 5 in the mouth 6 or between the Inner shell 3 and the outer shell 4 may be provided.
- These louvers 15 are approximately rectangular in shape and extend in the illustrated 1 in the upper section and in lateral sections of the tailpipe 2.
- these can Slots 15 also have a different geometric shape and also locally be arranged appropriately adapted to the tailpipe 2, such as in lower section of the tailpipe 2.
- the end pipe 2 is fastened to the exhaust pipe 1 using fastening means, for example, via screws 16 on either side of the tail pipe 2 on the Inner shell 3 are held.
- fastening means for example, via screws 16 on either side of the tail pipe 2 on the Inner shell 3 are held.
- To fix the screw 16 on the Inner shell 3 serves a clamping nut 17 which is pushed over the end wall becomes.
- a recess 18 is provided in the outer shell 4 so that the screws 16 can be positioned accordingly.
