SU1234688A1 - Cooling device built in brake disk which rotates on shaft - Google Patents

Description

The invention relates to mechanical engineering and can be used in devices requiring the removal of generated heat, for example, in disk brakes of railway rolling stock.

The purpose of the invention is to increase the cooling efficiency by accelerating the movement of the condensate.

The drawing shows schematically a cooling device embedded in the brake disc, a cross section.

The device contains a hollow hermetic casing 2 mounted on the shaft 1 and rigidly connected to the brake disk, with end faces 3 friction and heat generation, which, when braking each other

spring capillary-porous liner 7 (damping body) in an elastic ferromagnetic sheath 9 traveling mechanical wave. In this case, the electromagnetic force of attraction will be maximal at points under the instantaneous poles of the inductor 10. Under the action of this force, the elastic ferromagnetic shell 9 deforms to form a depression of the mechanical wave in the regions of the said poles of the traveling electromagnetic wave and the crest of the mechanical wave between the instantaneous poles of the inductor 10.

The formation of depressions and ridges of a traveling mechanical wave is promoted by the fact that the inductor 10 acts on an elastic ferzing body, which is made in the form of an elastic spring of a capillary-porous insert 7.

Thus, in the insert 7 is created

they act with brake pads 4, zomagnetic-shell 9 through evaporation damping 5 and condensation zone 6, located respectively in the zone of friction and heat generation and in the finned peripheral part of housing 1, elastic, springy

capillary-porous liner 7, impregnated with 2o traveling mechanical wave, directed

heat carrier 8, which changes its ag-from the condensation zone 6 to the evaporation zone 5,

The regatta state, and the ends of the enclose 2 inside the shock wave under the influence of this wave, the elastic ferromagnetic air 7, the condensate 9 located in zone 6, filled with damping telomia, actively absorb (suck in) the fluid, and the inductor 10 s. running electro-coolant 8, and through the ends of the liner

field that excites through 25 7, located in the evaporation zone 5, the fluid damping body 7 into the elastic ferromagnetic heat carrier 8 from the body of the insert 7

The mechanical casing 9 running mechanical is squeezed out and is thrown preferentially onto the inner surface 3 friction

The device works as follows. And generating heat from case 1.

When rotating mounted on the shaft 1, the characteristic feature of the operation of the cooling box 2 is under the influence of the centrifugal device that gives the brake disc 35

forces the heat-transfer fluid 8 is located in the cavity of the finned condensation zone 6, from which a capillary-porous liner

7, heat carrier 8 enters evaporation zone 5. During the braking process, the brake pads 4 are pressed against the end surfaces 3 and as a result of friction, heat is generated, which turns the heat-transfer fluid 8 into another state of aggregation into steam.

During the phase transformation of the coolant

8, from the end surfaces of the friction brake disc 3, heat is actively extracted, which is transported together with the vaporized body carrier 8 under the action of centrifugal forces into the cavity of the finned condensation zone 6, and then the developed finned surfaces remove heat into the surrounding environment with an air stream.

The liquid telesingle carrier 8 (condensate) from the condensation zone 6 again enters the evaporation zone 5 through the body of the elastic, spring-loaded capillary-porous insert 7, and the cycle of operation of the device repeats.

The peculiarity of the device operation is that at the moment of deceleration an inductor 10 is switched on with a running electromagnetic field, which excites through an elastic one.

It is found that during the period of absorption (absorption) of the liquid heat carrier 8 into the body of the elastic, capillary-porous liner 7, the suction forces from the traveling mechanical wave are added to the capillary suction forces, and during the emission and squeezing of the liquid heat carrier 8 from In addition to the extrusion forces from the traveling mechanical wave, the bodies of the liner 7 also exert centrifugal forces from the rotating brake disc on the extruded heat-transfer fluid 8, which cause the heat-expelled heat transfer fluid 8 to move to the inner face The new surface is 3 friction and disk heat generation not covered by a capillary-porous liner 7. The latter circumstance is very important, since in the proposed device the end surfaces of the 3 friction and disk heat generation are not covered by a capillary-porous liner layer.

The elimination of the capillary-porous coating on the end surfaces of the 3 friction and heat generation significantly reduces the thermal resistance to the flow of heat generated and, consequently, increases the cooling efficiency of the brake disc.
