The invention relates to the automotive industry and can be used in the design of major bridges. Famous Carter, made with a base support surfaces, with possibility of installation in him leading the pole is of ineni; design; reduced reliability, durability and guarantee the ability of the adjustment movement of bearing assemblies; a decrease in the absorption of the inner surface of the casing; lowering the strength of the shell of the crankcase due to the lack of a mesh pattern.

The purpose of the invention is the improvement of technological capabilities and versatility of the sump.

This is achieved by the fact that the crankcase is made with the base support surfaces, with the possibility of installing it pinion-shaft with bearing units, characterized in that it is made with three planes of the connector, two of which are designed to interact with certain elements of the nodes of the differential and gearbox and perpendicular to the third, intended to interact with the parts of the gear case and pinion-shaft, one flange of the crankcase is made elliptical, closed the ring box and with opposed spaced curved grooves on the major axis of conditional ellipse with overlapping radial protrusion of the bearing unit differential, within the crankcase is made of an opposed spaced pockets that serve to hold and capture the oil with the possibility pic is of Shema made net fin surface layer outside the zone, which serves to reduce the operating temperature of the gearbox, with respect to each plane of the connector is made perpendicular holes for connection with the mounting and installation elements, and the holes (at least one of the flanges have notches to align the flange with the inner plane of the connector and the cavity of the casing, the ribs are made inside and out in parallel and opposed relationship with these pockets to capture oil and portions of issuance through these openings communicating with the internal cavity of the housing.

The advantages of the new technical solutions are available Carter has multiple flanges, contributing to the invariance of its use, and compactness Carter, derived from the displacement of the bearing unit in the light box, an annular flange.

The oil pockets associated with pouring holes, can improve the performance properties of the timing mechanisms that are installed in the sump.

The fins on the end of the elliptical flange can improve the strength of the flange surface and to increase the heat transfer design due to the additional contact area of heat exchange.

The description of the design of the crankcase 1, the accessory connectors which you can use the multi in the exploitation of the various gears.

The flange 2 is coming to an elliptical form, which has the same name. He has a cylindrical hole 3 and the screw holes 4 and 58. Relatively more elliptical axis 5 posted by opposed radial recesses 6 and 7 in relation to the axis 12. The flange 2 contoured surfaces 8-11, and its inner profile selektivnye elements. End surface of the split areas of the bearing unit are arranged about the axis 12, and the surfaces 21 to 24 (Fig.1 and 6) with the screw holes 57. Partial digs a plane of the connector bearing unit indicate discontinuities inside of the housing of the bearing arrangements are made integral with the structural elements of the crankcase 1, presented in the form of cavities 25 and 26.

Oil pockets 27 are located with respect to axis 5, and bearing assemblies provided with grooves 28 for the formation of the screw profiles 55 and 56.

Boarding cylindrical surface 53 and 52 runs for the installation of bearings and threaded profiles, and then 55 and 56 serve to hold and based in the axial direction of the ring nuts with internal cut.

The plane 29 overlaps the shape of the opening 30 with the axis 31, the inner surface of the flange 37 is transferred to the mating of the surfaces of the outer profile 54, 59 and 60.

Mentioned flange 37 (see Fig.7) is provided with a cylindrical hole 49 and heavy grooves 50, and the screw holes 48 provide the ability to attach the flange 37 to the pressurized parts of the gearbox (see Fig.7), where, as in Fig.8, reflected chamfer 51.

At the end of the flange pridajut greater rigidity bearing bearing surfaces 42 and 43, this segment cut ring 29 box 30 contributes most to the compact design of the sump.

Cross section a-a is made by the oil pocket 33 and forth on section b-B shown his constructive perform.

The section b-b shows the relationship between the capacity of the pocket 34 with a hole 35 and the annular recess 36 of the flange 37. Net fin 41 is performed on the flange 2 and the side holes 45 with countersunk surfaces 44. Holes 49 with grooves 50 are reflected in Fig.8.

Industrial usefulness lies in the compactness of the geometrical shape of the crankcase, in the new invariant technological capabilities when used along with addressing the capture and sludge supplied lubricant, increased thermal conductivity due to the introduction of a beading mesh character, improving the strength of the crankcase, reducing the cost of manufacture triplezero Carter.

Carter performed with the base support surfaces with the possibility of installing it pinion-shaft with bearing units, characterized in that it is made with three planes of the connector, two of which are designed to interact with certain elements of Oslo the gear and pinion-shaft, one flange of the crankcase is made elliptical closed the ring box and with opposed spaced curved grooves on the major axis of conditional ellipse with overlapping its radial protrusion of the bearing unit of the differential, while the inside of the crankcase is made of an opposed spaced pockets that serve to hold and capture the oil with the possibility of subsequent extradition to the rubbing surfaces of the gearbox, with specified flange on the opposite side of the connector is made of a mesh fin surface layer outside the zone, which serves to reduce the operating temperature of the gearbox, with respect to each plane of the connector is made perpendicular holes for connection with the mounting and installation elements, and some of the holes, at least one of the flanges, is made with grooves to align the flange with the inner plane of the connector and the cavity of the casing, the ribs are made inside and out in parallel and opposed relationship with these pockets to capture oil and portions of issuance through these openings communicating with the internal cavity of the housing.
