Abstract

820,426. Fluid-pressure brakes. SANFORD, R. S., EATON, W. A., SEDERGREN, E. D., CASLER, R. H., and EAMES, J. O. June 7, 1957 [June 11, 1956], No. 18136/57. Class 103 (1). In fluid - pressure brakes of the type set forth in Specification 801,073, wherein friction elements are cooled by a circulating liquid under pressure, such liquid being further pressurized for effecting engagement of the friction elements 29 and 41, in Fig. 1, the brake-plate 20 is slidably mounted on the inner surface of member 18 and carries friction-rings 22, the friction elements 29 and 41, which are preferably of a highly conductive metal such as copper, being corrugated on their back faces to increase heat flow to cooling liquid flowing in channels 26 and 40 below the elements. As shown in Fig. 1, a piston 33 of rigid type is disposed below the left-hand friction element 41 and slidable in the stationary brake cylinder member 13. The liquid spaces behind the friction elements to each side of the brake disc are connected by registering ports 47 and 48 in the two halves of the members 13 and 14. The circulation of cooling and actuating liquid through the brake takes place in the following manner. Liquid is supplied to the plenum chamber 49 and thence to the cylinder or pressure chamber through cored passages 34 and port 37. From this point the cooling liquid circulates through the cylinder and enters channel 40 in the piston through inlet port 55. It then circulates through the channel and discharges through a tubular dam mechanism 56 shown in detail in Fig. 3. From the passage 59 behind the dam 56, it passes to the outlet from the plenum chamber and an outlet port (not shown). In an alternative embodiment there are two axially spaced brake discs, which are forced towards each other against a central member through which the cooling liquid is circulated.
