    The object of this invention is to improve the performance of the tulip members in the regions of connection or attachment between the petal portions and the adjacent shaft, this result being obtained by simple means. For this purpose, whereas the rest of the member (the raceways, bottom, cavities for the attachment of members effecting an axial retention) is carburized or carbonitrided, the connection regions are substantially devoid of any carburizing or carbonitriding.

    The invention relates to mechanical engineering and can be used in the production of cardan joints. Hinges are known, consisting of pins on which rollers are mounted with the possibility of rotation, and forks containing a shaft with three ramifications, including jumpers and ends with rolling surfaces. contact with the response elements in the form of rollers, which are a two-layer metallic body in layers of different composition, the outer layer of which is cement-bath or nitro-cemented steel: A plug is made obom comprising cementing or nitrotsementirovanie followed by quenching and tempering. Bending resistance — twisting the fork — determines the maximum torque that can be reached at the hinge and, consequently, at the gearbox. Although heat treatment by cementation or carbonitriding increases to a large extent the resistance of the rolling surfaces of the ft of olies or other rolling bodies, they are a result of a significant decrease in the resistance to normal and tangential stresses developed during torque transmission in the area of jumpers that does not get - due to the possibility of static destruction, use hinges with the maximum capacity are known. The purpose of the invention is to increase the service life of the fork by increasing the moment of static p zryva. The goal is achieved in a fork for a three-lobe hinge containing a shaft with branches in the form of petals, including law 1 associated with the shaft; surface rolling,. which are a two-layer metallic body, the outer layer of which is cemented or nitro-cemented steel and lintels connecting the shaft with the tips, the lintels are single-layered. The goal is achieved by the cementing or nitro cementation followed by quenching and tempering, prior to cementation or nitro cementation, a protection is applied to the surface of bridges Alloyed before quenching and tempering. In addition, the protection is a lacquer coating. Protection may also take the form of metallic plates. FIG. 1 shows a fork for a three-lobe bow; in FIG. 2; a cut A — A in FIG. one; in fig. 3 - spaced bb in fig. 2; in fig. 4 is a diagram illustrating the relationship between the transmitted torque and the angle of elastic torsion of the shaft P, the plug for the three-lobe hinge is metallic. body and contains shaft 1 with branches 2, including jumpers 3, and ends 4 with sockets 5 for fastening an axial retention part (not shown) and rolling surfaces 6 FOR: contacting with response elements in the form of rollers (not shown). On the side of surfaces 7 and 8, the body of the fork in the zone of the jumpers 3 is made of a single layer and consists of steel. The body of the plug on either side of the jumpers 3 represents a two-layer metal body of various composition in layers in which the material under the outer layer is steel, and the material of the outer layer is cemented or nitrocentered steel. The plug is made as follows. After shaping the preform, prior to cementation or carbon cementing on the lintel 3, surfaces 7 and 8 impose a protection, which can be a lacquer coating or metal lining in response to the lintel shape 3. After cementation or carbonitriding, the protection is removed and the fork is subjected to a subsequent, forging or tempering. Example. When implementing the technical solution, steel of the following composition is used, weight. %: carbon 0.24-0.31; magnesium 0.6-0.85; -chromium 0.95-1.25; Molebden 0.2-0.3. The jumper protection 3 on the side of surfaces 7 and 8 with a heat-resistant lacquer of the type CONOVRSAL / Carried out cementation to a depth of. 0.5 mm in the gas phase at 800 ° C in a furnace, then quenched in oil directly at the exit of the furnace and tempering at 140-1 ° C. . Due to the application of the proposed EMT technical solution, the static resistance of the FORK FORT to rupture increases. In the diagram shown in FIG. 4, curves C and D show the dependence between the transmitted torque and the angle of elastic torsion of the shaft when using correspondingly known and proposed technical solutions. From the diagrams, it follows that the minimum torque M goes from 150 kgcm in the known device to about 195 kgf-m in the proposed, and the elastic torsion angle H is from 30 to 45 °.
