Abstract

1,271,745. Fluid pressure control of brakes; hydrostatic transmission. SOC. D'APPLICATIONS DES MACHINES MOTRICES. 5 June, 1969 [6 June, 1968], No. 28494/69. Headings F2D and F2F. [Also in Divisions F1 and G1] Fluid pressure control of brakes (Fig. 1).-The output shaft 15 of an hydraulic motor (see Division F1) is prevented from moving when the motor is inoperative by a brake V comprising movable and fixed discs urged together by a spring 24. Release of the brake is effected by supplying pressurized liquid to a connection 26, thereby to move a piston 25 to the right and cause compression of the spring 24 by a member 23. Liquid is supplied to the connection 26 by a hand or power operated pump. Hydrostatic transmission (Fig. 2).-The hydraulic motor 40 has servo control of its position and speed. During speed control the output from a tachogenerator 30 driven by the motor is compared with the output from a speed control potentiometer 50, the resulting output being fed to an amplifier 47 supplying a torque motor 48. The motor 48 adjusts the output of a pump 41 feeding the motor 40, thereby to obtain the desired speed. Switches and a contactor 44 are moved to positions P o when position control is required. Filters 46<SP>1</SP>, 46<SP>11</SP> and a combined amplifier and demodulator 45 are provided in the amplifier circuit.
