    The invention relates to mechanical engineering, in particular to engine building, and can be used in the design of pistons for internal combustion engines (ICE),
    The aim of the invention is to increase reliability.
    Fig, 1 shows a piston, a longitudinal section; figure 2 - section aa in figure 1} in figure 3 - section bb in figure 2.
    The piston for the engine contains the head 1 and the body 2, which is pivotally connected to the connecting rod 3 via the pap 4.
    The head 1 rests on the body 2 through two supporting surfaces 5 and 6 of circular shape and is connected with the body with the help of fastening elements (not shown),
    The body 2 has a separate skirt, however the body and the skirt can not be made as a whole.
    The housing 2 has a bearing 7, consisting of a wall B on the side of the piston head, forming a solid half of the bearing across the entire width of the housing, and on the connecting-rod side of two half-bridges -: - hips 9 located on both sides of the connecting rod,
    Wall 8 forms a semicircular bearing surface 10, along the entire width of the piston core.
    This bearing 7 serves as a support for the pin 4 attached to the end of the connecting rod 3 by means of fastening means
    The wall 8 is connected to each support surface 5 and 6 of a round shape with the help of thin partitions 11 and: 2
    in the shape of a truncated cone. Thickness

    and the profile of these partitions may be variable and vary depending on the position of the horizontal section plane.
    The support surfaces 5 and 6 are interconnected by means of an annular partition 13. Thus, this partition interconnects the tops of the partitions 11 and 12 and is active; participates in increasing the rigidity of the piston core.
    This annular partition 13 forms, with partitions 11 and 12, and with a wall 8, an annular cavity 14, and an ac head 1 — an annular cavity 15.
    The system needed for lubrication and cooling is formed by a hole
    16, through which the oil flows, again rising to the connecting rod, groove
    17, made in the bearing surface 10 of the wall 8 n in the bearing, if any, with two small slots 18 and 19, (FIG. 2), also made in the supporting surface 10 of the wall 8, with two vertical channels 20 extending into the cavity 15, channels 21 located around the circumference and communicating the cavity 15 with the central cavity 22, channels 23 communicating the central cavity 22
    with an annular cavity 14 and, finally, channels 24 connecting the annular cavity 14 with the inner part 25 of the skirt, as a result of which the oil is again drained down into the crankcase.
    The geometric points 26 and 27 of the meeting of the middle axes of the partitions 11 and 12, respectively, are located relative to the support surface 10 of the wall 8 on the side of the finger 4. In general, for any piston in diameter, i.e. dp of any sectional planes located between sectional planes (Figures 1 and 2), the intersection points of the middle axes are located on the side of the finger 4 between the surface 10 and the axis of the finger
    The points 28–31 of the intersection of the middle axes. The barriers 11 and 12 with the supporting surface 10 of the wall 8 define segments or successive arcs of the curves 28–29, 29–30, 30–31. The ratio of the length of the smallest segment to the length of the largest is not lower than 0.1, and preferably these segments should have a relatively equal length for the best distribution of forces on the bearing surface of the 28 and 31.
    In the form of truncated cones, internal and external, forming cooling cavities, the intersection points of the axes of the partitions are located on the finger side, and the internal cone is connected with the upper bearing surface, characterized in that, to increase reliability, the partition of the external cone associated with the lower support surface.
    2. Piston in accordance with claim 1, the use of which is the intersection point
    Invention Formula
    1. Piston mainly for engines 25
    middle axes of the partitions are located 15 between the bearing wall and the longitudinal axis of the piston pin.
    3. The piston according to PP.1 and 2, which is the fact that the intersection points of the middle axes of the partitions with
    10 between the point 20 of the bearing surface of the bearing wall form segments and / or successive arcs of the curve, the ratio of the smallest to the greatest length of which is not less than 0.1.
