Abstract

653,565. Brake cooling systems. DUNLOP RUBBER CO., Ltd.,' and PENDLEBURY, J. A. May 7, 1948, No. 12561. [Class 103 (i)] A brake friction member is cooled by liquid sucked into the interior of said member by means of an injector device located thereir and actuated by vapour generated frorr the liquid by the heat produced in braking. In Fig. 5, the invention is shown applied to an aircraft wheel assembly having a fixed axle 27, rotating wheel hub 23 and friction pads 35, 36 moved axially by a conventional fluid pressure actuator 38 into engagement with the rotatable brake member 1, 2. The brake member is made in two halves 1 and 2, with a series of interleaving fins 3 and 6 which together provide a system of sinuous passages within the member. Spaced at equal intervals around the brake member and located between the two halves 1 and 2 are three radially extending injector assemblies, as shown in Fig. 3. Each injector assembly comprises a jet 8, converging nozzle 11, diverging nozzle and ball valve 13, 14, 15 and vapour outlet passage 17a. Spaced between the injector assemblies are exhaust assemblies 20, Fig. 4, comprising inlet ports 21, radially extending tubes 19 and relief valves 22 set to open at approximately 75 lbs. per square inch. Cooling of the brake takes place as follows. When braking is about to take place, a valve is operated to allow cooling liquid to flow through passages 33b, 33a, into the annular chamber 33 around the internal diameter of the brake member. When the brake is applied the heat generated vaporizes a quantity of liquid that has been left in the brake member from a previous application. This vapour begins to eject from the nozzle 8 and in so doing sucks up liquid from chamber 33 and forces it from the convergent nozzle 11 into the divergent nozzle 13 and past the ball-valve 14, 15 to circulate around the passages within the brake member until this liquid is itself vaporized. Excess vapour escapes by the passage 17a and outlet 18, the pressure within the brake being limited by the relief valve 22. A system is thus provided in which the circulation of cooling liquid is automatically varied in proportion to the heat generated in braking. Cooling fluids that may be used are water, alcohol, ethylene glycol or a mixture thereof.
