Description
лени воздуха в тормозах. Система регулировани снабжена клапаном 28 и управл емым электромагнитом клапапом 29.laziness of air in the brakes. The control system is provided with a valve 28 and an electromagnet-controlled valve 29.
Давление с выходов ласосов 1 и 2 подаетс по линии 30 на один конец, а давление из резервуара 3 - по линии 31 на другой конец рычага 32, управл ющего через механическое соединение 33 положением регулирующего клапана 34 устройства дл сравнени давлени .The pressure from the outlets of lassovs 1 and 2 is supplied through line 30 to one end, and the pressure from tank 3 to line 31 to the other end of lever 32, which controls the pressure comparison device 34 through mechanical connection 33.
Рычаги 35 -и 36 привод т в действие механические тормоза 37 и 38 посредством подачи жидкости из резервуара 39 насосом 40. Кланан 41 с электромагнитом 42 служит дл отключени давлени и, следовательно, ослаблени действи механических тор.мозов 37 и 38. Электромагнит 43 клапана 14 питаетс по проводам 44, а переключающий клапан 15 - по проводам 45 с переключателем 46.Levers 35 and 36 actuate mechanical brakes 37 and 38 by supplying fluid from tank 39 by pump 40. Clanan 41 with electromagnet 42 serves to turn off pressure and, therefore, relieve mechanical brakes 37 and 38. Solenoid 43 of valve 14 It is powered by wires 44, and the switching valve 15 is powered by wires 45 with switch 46.
При торможении гидродинамического тормоза проводитс подача рабочей жидкости (масла или воды) к «асосам 1 и 2, которые возвращают ее в резервуар 3. Клапан 13 освобождает клапана 9 и 10, служащие дл соединени или отключени напорного резервуара 3 от подающих линий, следовательно, дл отключени потока рабочей жидкости, текущей к насосам 1 и 2. Также работают и клапана 14 и 15. Давление в резервуаре 3 регулируетс клапаном 16, который при пулевом токе занимает такое положение, чтобы в резервуар 3 поступало давление, создающее задапную степень торможени , благодар чему при несрабатывании электромагнита 17 срабатывают тормоза.When the hydrodynamic brake is braked, the working fluid (oil or water) is supplied to the pumps 1 and 2, which return it to the tank 3. The valve 13 releases valves 9 and 10, which serve to connect or disconnect the pressure tank 3 from the supply lines, therefore shutting off the flow of the working fluid flowing to pumps 1 and 2. Valves 14 and 15 also work. Pressure in tank 3 is regulated by valve 16, which in a bullet current takes up such a position that pressure is applied to tank 3, creating a given degree of deceleration voltage, whereby when a failure of the electromagnet 17 are activated brake.
При протекании тока в одном направлении, при величине его, завис щей от требуемой степени замедлени подвижного состава, он будет снижать давление в резервуаре и, следовательно , уменьщать тормозной момент дл снижени степени аварийного торможени до требуемого уровн .When current flows in one direction, at a value that depends on the required degree of deceleration of the rolling stock, it will reduce the pressure in the reservoir and, therefore, reduce the braking torque to reduce the degree of emergency braking to the required level.
Механические тормоза привод тс в действие через регулирующий клапан 34, управл ющий давлением жидкости, поступающей на рычаги 35 и 36 из резервуара 39 при помощи насоса 40.The mechanical brakes are actuated through a control valve 34 controlling the pressure of the fluid supplied to the levers 35 and 36 from the reservoir 39 by means of a pump 40.
Когда гидродинамический тормоз разовьет требуемый тормозной момент, клапан 34 устанавливаетс в положение, при котором давление , привод щее в действие механические тормоза, снижаетс . Однако, когда тормозной момент гидродинамического тормоза становитс ниже требуемого, положение клапана 34 измен етс , благодар чему создаетс достаточное давление масла дл повышени тормозного момента за счет механических тормозов 37 и 38.When the hydrodynamic brake develops the required braking torque, the valve 34 is set to a position in which the pressure driving the mechanical brakes is reduced. However, when the braking torque of the hydrodynamic brake becomes lower than the required one, the position of the valve 34 is changed, thereby creating sufficient oil pressure to increase the braking moment due to the mechanical brakes 37 and 38.
Таким образом, устройство дл сравнени давлений жидкости в выпускном трубопроводе с давлением в резервуаре посредством рычага 32 и клапана 34 обеспечивает получение необходимой тормозной эффективности за счет гидродинамического или механического тормозов.Thus, a device for comparing the pressures of fluid in the discharge pipe with the pressure in the reservoir by means of the lever 32 and the valve 34 ensures the required braking efficiency due to hydrodynamic or mechanical brakes.
