Phage 1. The image relates to mechanical engineering. A braking disk is known, consisting of a roll flat ring, both of which are working walls, the inner cavity of the ring, the pylons of the longitudinal partitions and partially filled with liquid, while the internal surface of the partitions is covered with porous material and made possible for the passage of fluid between the partitions I. However the disk does not provide reliable cooling, since it is heated and cooled by liquid in the same cavity, which is separated only by partitions. The closest to the invention in terms of the result achieved and the function performed is a braking disk consisting of a hollow flat ring, one of the end walls of which is working, the internal cavity of the ring is made as separate segments separated from each other by radial partitions and partially filled with liquid, with the inner end surface of each segment covered with a porous material, on the outer side of the end non-working Circled around the circumference 2. The known device allows the brake disc to cool, yo due to the lack of circulation of the liquid cooling the working surface of the disc is not enough. The aim of the invention is to increase the cooling efficiency. The goal is achieved by the fact that the brake disc consisting of a hollow flat ring, one of the end walls of which is working, the internal cavity of the ring is made up as separate segments separated from each other by radial partitions and partially filled with liquid). the segment is covered with a porous material, and on the outer end non-working surface of the ring there are rigidly mounted cooling fins, evenly spaced around the circumference, provided with an additional hollow ring, strictly connected to the main jumpers, evenly spaced around the circumference, the internal cavity of the additional ring is made in the form of segments, separated by partitions, and cooling fins are made on the external end surface of the additional ring, while the jumpers are made over the entire width of the rings, placed between the partitions Inside each of them, at the periphery and in the end walls of the rings in contact with them, through holes are made. ... In FIG. 1 shows a brake disc, cross section; FIG. 2 - section A-A. In FIG. one; in fig. 3 shows a section BB in FIG. I; FIG. 4 is a section through BB in FIG. 3. The brake DNA consists of a hollow flat ring 1, the end wall of which is 2 working, the internal cavity 3 of the ring 1 is made as separate segments 4 separated from each other by radial partitions 5 and partially filled with liquid, and inside each segment 4 wall 2 it is covered with porous material 6, and an additional hollow ring 7, rigidly connected, for example, by welding with ring I with jumpers 8, evenly spaced around the circumference. The internal cavity 9 of the ring 7 is made in the same way as the internal cavity 3 of the ring 1, in the form of segments 4 separated from each other by radial partitions 5, and fO cooling edges are made on the outer surface of the ring 7. Lintels 8 are made on the entire width of the rings 1 and 7, placed between the partitions 5 and vnutr; Each of them, on the periphery of the end walls of the rings mating with them, has through holes 11 and 12. In addition, jumpers 8 together with the non-working walls of rings I and 7 form ventilation ducts 13. The brake disc works in a manner. When the disk rotates, the liquid is poured in the cavity 3 and; 9 rings 1 and 7, under the dei; The inertial forces are located in the periphery of these cavities. When the working wall 2 rings 1, the liquid evaporates from the porous materials 6. The steam fills the cavities 9 of cavity 7 through rings 7 and condenses on its surfaces as cooler. as an additional hollow ring 7 is washed on all sides by oncoming air, the condensation process. the vapor in the liquid occurs more rapidly. The condensate flows under the action of inertial forces into the peripheral part of cavity 9 and through the opening 11 enters the cavity 3 of the ring 1 for evaporation. The heat released during condensation is removed from the outer surface of the ring 7 by means of cooling fins, and from the inside by air flow in the ventilation ducts. The invention makes it possible to cool the brake disc efficiently both by circulating a cooling fluid inside the disc and by forcibly cooling the fluid through cooling fins and ventilation ducts.
