Abstract

FIELD: mechanical engineering. SUBSTANCE: multiple-circuit brake drive has setters 11,22-22, pressure transmitters 2 23-23connected in tandem with direct input 31 of operational amplifier 3 and input 26 of logic control device 5 through one of analog signal switches 11 in parallel with one of constant resistors 15. Variable resistors 13-13are connected to supply source and to other switch 10. Constant resistor 14 is connected in parallel with switch 10. Amplifier 3 is connected by its inverse input 29 to switch 10 and through feedback resistor 16 it is connected to its output 27 and input 26 of device 5 whose output 24 is connected through bus 21 with switches 10 and 11 and outputs 25 are connected with each corresponding circuits 7, 18-18. In process of operation conversion channels are formed constantly and successively. Each channel consists of setter and pressure transmitter, corresponding variable resistor 13-13, first and second switches 10 and 11 and amplifier 3 common for all channels, input signals processed by device 5 are directed successively to modulators 5, 17-17of each corresponding circuits 7, 18-18, thus providing required pressure in corresponding brake chambers 9, 20-20by connecting to them, when necessary, corresponding accumulators 8, 19-19. EFFECT: provision of high accuracy of control owing to temperature stability of standard elements of conversion channels. 1 dwg

Тормозной привод выполнен многоконтурным и содержит задатчики 221 - 22n, датчики 231 - 23n давления, подключенные последовательно к прямому входу операционного усилителя и входу логического управляющего устройства через один из коммутаторов аналоговых сигналов параллельно одному из постоянных резисторов, переменные резисторы 131 - 132(n+1) подключены к источнику питания и к другому коммутатору, параллельно которому установлен второй постоянный резистор. При этом усилитель своим инверсным входом подключен к коммутатору, а через резистор обратной связи - к своему выходу и входу устройства, выход которого шиной соединен с коммутаторами, а выходы - с каждым из соответствующих контуров 181 - 18n. В процессе работы устройства постоянно и последовательно образуются преобразовательные каналы, каждый из которых состоит из задатчика и датчика давления, соответствующего ему переменного резистора 131 - 132(n+1),первого и второго коммутаторов и единственного для всех каналов усилителя. Проанализированные устройством входные сигналы направляются последовательно к модуляторам 171 - 17n каждого из соответствующих контуров 181 - 18n, обеспечивая необходимое давление в соответствующих тормозных камерах 201 - 20n, подключая к ним при необходимости соответствующие аккумуляторы 191 - 19n. При этом обеспечивается высокая точность регулирования, благодаря температурной стабильности стандартных элементов преобразовательных каналов.The brake actuator is multi-circuit and contains a set of 22 1 - 22 n , pressure sensors 23 1 - 23 n , connected in series to the direct input of the operational amplifier and the input of the logical control device through one of the analogue signal switches parallel to one of the constant resistors, variable resistors 13 1 - 13 2 (n + 1) are connected to a power source and to another switch, in parallel with which a second fixed resistor is installed. In this case, the amplifier is connected to the switch with its inverse input, and through the feedback resistor to its output and the input of the device, the output of which is connected to the switches by a bus, and the outputs are connected to each of the corresponding circuits 18 1 - 18 n . In the process of operation of the device, converter channels are constantly and sequentially formed, each of which consists of a master and a pressure sensor, its corresponding variable resistor 13 1 - 13 2 (n + 1) , the first and second switches and the only amplifier for all channels. The input signals analyzed by the device are sent sequentially to the modulators 17 1 - 17 n of each of the corresponding circuits 18 1 - 18 n , providing the necessary pressure in the respective brake chambers 20 1 - 20 n , connecting the corresponding accumulators 19 1 - 19 n to them, if necessary. This ensures high accuracy control due to the temperature stability of the standard elements of the conversion channels.
