Vehicle exhaust system

The invention relates to the field of mechanical engineering and can be used in vehicles, in particular in suction and exhaust systems.

A known exhaust system of a vehicle exhaust gas comprising receiving and exhaust pipes, a compensator, a silencer, an exhaust pipe with a resonator, an additional resonator mounted between the receiving and exhaust pipes, the length of the receiving pipe is four lengths of the additional resonator (1). In the case when the construction of the vehicle is used in several versions with different. engines, the direct connection of the intake pipe of the system: exhaust with a specific engine becomes impossible due to the difference in size of the connected elements. This does not allow to increase the range of products.

This problem is partially solved by the vehicle exhaust system, containing the intake and exhaust pipes, a compensator, an adapter and a silencer with an exhaust pipe, a compensator flange connected to the adapter flange (2). The presence of the adapter allows you to use a specific exhaust system when installing various types of engines on a vehicle. However, the implementation of the adapter in the form of an integral sleeve with flanges complicates the assembly of ШМПК: В60К 13/04

disassembling the exhaust system. In addition, temperature expansions in the elements of the exhaust system can cause deformation and jamming of the adapter, which reduces the reliability of the exhaust system.

The proposed utility model solves the problem of using various engines in vehicles to expand the range of products while increasing the reliability of the exhaust system

To achieve this technical result, a system is proposed. exhaust gas exhaust of the vehicle, which, like the well-known exhaust system, contains a intake and exhaust pipe :, a compensator, an adapter and a silencer with an exhaust pipe, the compensator flange is connected to the adapter flange. In contrast to the known, in the inventive exhaust system, the adapter is made integral of the flange AND of the detachable ring, the adapter flange is made in the form of a separate ring, the first end surface of which is associated with the compensator flange, the inner one with the corresponding surface of the final section of the receiving pipe, and the second the end surface - with the end of the split ring installed in the recess of the final section of the receiving pipe, and the flanges of the compensator and the adapter are rigidly connected to the split ring. For the best implementation of the task, the split ring of the adapter is made of two half rings.

The implementation of the adapter composite of a flange and two. half ring allows you to install various types of engines on a vehicle

and it compensates for the thermal expansion that occurs in the system, facilitating assembly and disassembly and increasing machine reliability.

The proposed utility model is illustrated by drawings, which depict: in Fig.1 - vehicle exhaust system; figure 2 is an enlarged image of I in figure 1; in Fig.3Z-section AAA in Fig. 1., The exhaust system of the vehicle’s exhaust gas includes a receiving 1 and an exhaust pipe 2, a muffler 3 with an exhaust pipe 4, a compensator 5 with a flange 6, an adapter 7. The adapter is made integral of the flange 8 in the form a separate ring and two half rings 9. The first end surface of the flange 8 is associated with the flange 6 of the compensator, and the second with the half rings 9. The inner surface of the adapter flange 8 is in contact with the corresponding surfaces of the end. h part of the receiving pipe 1. Half rings 9 are installed in the recess 10 of the final section of the receiving pipe 1. Flange 6 of compensator 5, flange 8 and half rings 9 of adapter 7 are rigidly interconnected by bolts L.

When assembling the exhaust system, the half rings 9 are installed in the recess 10, and the adapter flange 8 is brought to the end of the final section of the receiving pipe 1 until they touch the half rings 9. The flange 6 of the compensator 5, the adapter flange 8 and the half ring 9 are rigidly connected to each other by bolts I. When the engine is running the gap between the half rings 9 of the vehicle avoids deformation and jamming of the adapter

with thermal expansion of the elements of the exhaust system. The proposed design allows you to expand the range of cars produced by the plant while increasing the reliability of the vehicle exhaust system.
