    • 专利摘要:
    An internal pipe (11) conveying the exhaust gases is arranged in a gas-tight housing (12, 13), which surrounds the pipe at a certain distance. The inner pipe (11) is made of several sections, the length of a section (15) corresponding approximately to the spacing between the cylinders of the engine. Each section (15) consists of two portions (15a, 15b) having the shape of a gutter, which, together with the flanges (18, 19) formed on both longitudinal edges, form the cross-section of the pipe when superimposed. The flanges (18, 19) of the gutter-shaped portions are secured by screws (22, 23) to the surrounding housing (12, 13). The manufacture of the inner pipe (11) from sheet while avoiding welded joints, enables particularly economical production and ensures a weight-saving design.

    专利说明:

    The invention relates to mechanical engineering, in particular to engine building, in particular to engine exhaust systems.
    The purpose of the invention is to increase reliability by compensating for the stresses previously created in the construction of the pipeline due to its thermal expansion.
    FIG. 1 shows a mounted collector, top view; 2 is a section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; Fig, 4 - section bb In Fig, 2; in fig. 5 - a collector with a cover, an end view; in fig. 6 shows a collector with a lid consisting of two halves, an end view; in fig. 7 - section G-Y in FIG. five; FIG. 8 is a section DD-D in FIG. 6; in fig. 9 - a collector with a lid consisting of four parts, an end view; in fig. 40 is a sectional view of FIG. 9; in fig. 11 - section MF in FIG. 1.
    The exhaust pipe contains at least one collector 1. A hermetic casing enclosing a collector consisting of cooled water parts 2 and 3. The collector 1 consists of separate sections 4, 5 and 6, and in the case of a multi-cylinder engine the collector 1 is located in the crankcase volume 7 of the engine between the V-shapedly arranged rows of cylinders. Each section 4, 5 and 6 consists of two tray-shaped parts 8 and 9, which, adjoining to each other flanges 10 and 11 flanged parallel to the axis of the section, form between them a cross-section of the pipeline,

    the length of each section is made equal to the distance between the cylinders. The tray-like parts of each of sections 4, 5, and 6 are installed with the formation of compensation gaps, which are covered by protective strips 12 and 13, which overlap the ends of the adjacent sections and are fixed when the screws are cracked. 14, and the sections 4, 5, and 6 themselves are secured against movements in the longitudinal and transverse directions by means of fixing screws 15. Spacers 16, which can be made of thermal insulation, are installed between the flanges and the casing at the points of their connection with screws 14 and 15. material. An intermediate plate 17 is installed at the point of attachment of the protective strips 12 and 13 to the casing, providing in the overlap zone the possibility of thermal expansion of sections 4, 5 and 6. The collector sections 1 are made with holes 18 to which gas exhaust pipes connected to the turbine are connected, and secured to the console 19 of the casing. Each section is connected to an individual exhaust pipe 20 cylinder. Fixing
    screws 15 are located in the connection zone of the individual nozzles 20,
    0 At both ends of the collector 1, removable covers 21-23 are installed, each of which is made convex and provided with a flange molded into the inside of the collector and in contact with the butt ends of the extreme lot-shaped sections.
    The cover 21 is made integral and fixed on the extreme section 4 in two places, and in one place it is rigid.

    and in another, the possibility of movement.
    The cover can be divided into two halves 22 and 23 with the formation of a compensation gap, with each half of the 22 and 23 caps being rigidly fixed to the end of the collector 1 with screws 24 and 25.
    The cover can be divided into four parts 26-29, on each of which a flange is formed, directed towards the inside of the collector and provided with a bent section, which, together with the flanges of the tray-shaped extreme sections of the collector 1, are fixed to the casing with screws 30.
    The exhaust pipe works as follows.
    When gases are released from the cylinders, they are delivered to the inside of the manifold 1 through the individual outlets 20 and out of it through the openings 18 to the turbine. With the passage of hot gases, the structure of the exhaust pipe is heated, which causes a change in the length of its elements. Partial compensation of thermal stresses in the construction of the pipeline is provided by creating prestresses during the expansion of the tray-shaped sections 4, 5 and 6 during the installation of the pipeline. The expansion is carried out by an amount which corresponds to the thermal expansion expected at the operating temperature. The pre-stress produced in the trough-like sections due to expansion is, in a cold state, a completely uncritical load that is compensated for when the operating temperature is reached due to thermal expansion.
    Also, the pre-stress generated in the cover is compensated for by thermal expansion due to the deformation of the convexity consistent with the contour of the collector end face 1.
    In addition to compensating the prestresses, the chute-shaped sections move in the axial direction, which is ensured by fastening the protective strips 12 and 13. The protective strips provide their installation with a force that allows to suppress the vibration of the tray-shaped sections.
    The implementation of the composite construction of the exhaust pipe allows increasing its reliability due to compensation18284. 6
    voltage variations., reduce vibration
    with the passage of gas flows through the flow part and to ensure reliable fastening of the collector in the housing.
