Abstract
Использование: изобретение относитс к транспортному машиностроению, а именно к устройствам дл плавного включени фрикционов коробок передач с большим гидравлическим сопротивлением каналов включени фрикциона Устройство включает источник давлени 1. гидрораспределитель 2. механизм 3 плавности и клапан 4 задержки срабатывани механизма 3. Конструктивные параметры клапана 4 таковы, что врем перемещени золотника 18 из исходного положени в крайнее правое несколько меньше времени окончани выбора зазоров между дисками. На первом этапе включени фрикциона во врем выбора зазоров и перемещени золотника 18 в крайнее правое положение гидроцилиндр 26 сообщен с источником 1 на пр мую в обход дроссел 33. а механизм 3 отключен от канала 24 На втором этапе после остановки золотника 18 гидроцилиндр 26 сообщаетс с источником 1 только через дроссель 33, а механизм 3 подключаетс к каналу 24. На этом этапе продолжаетс выбор зазоров. На третьем этапе после остановки поршн фрикциона в работу вступает механизм 3, обеспечива плавное нарастание давлени в гидроцилиндре 26. В конце рабочего хода поршн 8 плунжер 6 регул тора возвращаетс в исходное положение. В результате в гидроцилиндре 26 устанавливаетс номинальный уровень давлени . Одновременно золотник 18 под действием давлени жидкости, подводимой в его подпружиненную полость через каналы 25. 31 и полость 17, также возвращаетс в первоначальное состо ние. 2 илUsage: the invention relates to transport engineering, and in particular to devices for smoothly engaging clutches of transmissions with high hydraulic resistance of clutch engaging channels. The device includes a pressure source 1. a control valve 2. a smoothness mechanism 3 and a valve 4 for delaying the operation of mechanism 3. The design parameters of valve 4 are as follows that the movement time of the spool 18 from the initial position to the far right is somewhat shorter than the time that the selection of the gaps between the disks ends. At the first stage of turning on the clutch during the selection of gaps and moving the spool 18 to the extreme right position, the hydraulic cylinder 26 is connected to the source 1 directly bypassing the throttle 33. And the mechanism 3 is disconnected from the channel 24. In the second stage, after the spool 18 is stopped, the hydraulic cylinder 26 communicates with the source 1 only through the inductor 33, and the mechanism 3 is connected to the channel 24. At this stage, the selection of gaps continues. In the third stage, after the friction clutch piston stops, mechanism 3 enters into operation, providing a smooth increase in pressure in hydraulic cylinder 26. At the end of the stroke of the piston 8, the regulator plunger 6 returns to its original position. As a result, a nominal pressure level is set in the hydraulic cylinder 26. At the same time, the valve 18 under the influence of the pressure of the fluid supplied to its spring-loaded cavity through the channels 25. 31 and the cavity 17, also returns to its original state. 2 silt
