Exhaust pipe

The invention relates to an exhaust pipe for use in an exhaust system, especially in motor vehicles.

The invention has for its object to design an exhaust pipe that the inventory of exhaust pipes for · Exhaust systems is significantly reduced _{3, s} is necessary to vehicles beaspielsweiae school buses _s Trucks and 'like to keep in Stariu.

Exhaust system so that it is no longer necessary to keep long pipe sections of bulky shape in stock j can vary within wide limits from one vehicle to another,

Embodiments of the invention will now be based on the enclosed Drawings described. Show it:

tube 11, which is connected to the input or output of an exhaust "pot 13 are connected. The exhaust pipe 11 must go over the rear axle and the differential 15 of the vehicle 1 are guided ; and therefore has an arcuate portion 17 which extends over : the axis runs. The arch section 17 consists of a j upstream part 19 and a downstream part 21, which are identical before they are assembled (FIG. 2). The exhaust system 7, if necessary, additional pipelines can be j have, for example, the straight pipe 23 that connects the muffler 13 connects to the arch part 19, and a straight tube 25, the the arch part 21 is extended to the rear end of the bus, to release the gas into the atmosphere.

Each of the arch parts 19 and 21 has an essentially identical

are), is essentially Z-shaped and has diagonal j Sections A which are integrally formed with parallel sections B and C j and connect these sections. The sections C are longer than sections B. At the ends of parts 19 and 21 enlarged or widened and provided with slots sockets 27a, 27b, 27c and 27d are formed, which have such a size have that they receive the straight pipe sections 23 and 25 or at these sections or sections B or C of the Parts 19 and 21 can be clamped. It can be seen that • the staggered sections B and C are each parallel to the j original direction of the gas flow in the exhaust system 7 !are.

As indicated in FIG. 1, in the case of a bus 1 it is possible to obtain the necessary spacing by connecting two parts 19 and 21 without using an additional straight piece of pipe between these parts. In fact, this is possible with most of the school buses currently in operation. Therefore, in order to connect the parts 19 and 21 to one another, the widened end 27b is cut off so that the desired length remains of the part C, as indicated by the dashed line 29. Section C of part 19 then fits into socket ft 27c. Because of the slots, the socket can then be clamped in place by conventional clamping parts (not shown). Obviously, the socket 27c can be cut off instead of the socket 27b. Also, as already mentioned, a separate piece of pipe (not shown) can be inserted between parts 19 and 21 (Fig. 2) and clamped in sockets 27b and 27c if the obstacle around which the exhaust system must be guided does so makes necessary.

In the case of the rear axle 15, the exhaust pipe 11 of the exhaust system must be offset from the straight line of the main direction of the gas flow in the vertical direction. With the arch section 16 however, lateral deviations or displacements in the transverse direction can also be achieved in a simple manner. How through that curved lines 31 is indicated, the determined by the parts and 21 plane can be adjusted in its angular position j be that the parts are only rotated to the desired angle; v / ground before they are clamped. Through this attitude there is the possibility of changing the horizontal position of the upper part of the arcuate section 17, and furthermore

becomes an additional setting in a direction transverse to that Enables vehicle that bypassing shock absorbers, spare tires, rear doors, wheel chambers and the like. Is useful.

Although most school buses have exhaust systems which are satisfactorily assembled with the two parts 19 and 21 it is possible to use a third or even more Z-shaped sections if necessary.

Apparently the invention creates gas lines for an exhaust. system in the form of a spare part, which, if necessary, is put together. The exhaust lines are extremely simple and require a minimum number of parts minimal storage space, they are easy to assemble and install. The pipeline can be adapted to the requirements during installation of the respective vehicle. Hence, through the invention satisfactory, replaceable exhaust systems with at a minimum cost.
