хализм блокировки 9, выполненный в виде двухлинейного двухнозвционного гидрораспределител с толкателем 10, установленного на гид|роли«ии 11, 11, соадйн ющей трехлинейный гидрораопределитель 8 с гидродвигателем 7. Кулачковый механизм (выполнен в виде запирающего рычага 12 с роликом /5, жестко закрепленного на наклонной шайбе 14 регулируемого насоса 15 гидростатического прИБОда /, и коромысла 16, шарнирио закрепленного на раме и Имеющего два кулачковых профил в виде выемок 17 и 18 на коромысле . Выемка /7 взаимодействует с роликом запирающего рычага, а выемка 18 - с толкателем механизма блокировки.lock 9, made in the form of a two-line two-stage hydraulic distributor with a pusher 10 installed on a hydraulic role of 11 and 11, co-linking a three-way hydraulic indicator 8 with a hydraulic motor 7. Cam mechanism (made in the form of a locking lever 12 with a roller / 5 rigidly fixed on an inclined washer 14 of an adjustable pump 15 hydrostatic Pribo /, and a rocker arm 16 hinged on a frame and Having two cam profiles in the form of grooves 17 and 18 on the rocker arm. The notch / 7 interacts with the roller of the locking lever ha and recess 18 - a tappet of the locking mechanism.
Выемки 17 и 18 на коромысле 16 размещены таким образом, что положение ролика 13 в выемке 17 соответствует полол ению толкател 10 в выемке 18, обеспечива синхронизащию нейтрального положени наклонной шайбы насоса с открытой позицией механизма блокировки.The notches 17 and 18 on the yoke 16 are positioned in such a way that the position of the roller 13 in the notch 17 corresponds to the elimination of the pusher 10 in the notch 18, ensuring the synchronous neutral position of the inclined pump washer with the open position of the locking mechanism.
Регулирование скорости гидростатической передачи осуществл етс известным образом с ломощью дросселирующего гидрораспределител 19, золотник которого через рычаги 20--23 и т гу 23 св зан с рычагом 4 переключени скоростей. Выходные гидролинии распределител соединены -с полост ми гидроцилиндра 24, щток 25 которого щарнирно св зан с наклонной щайбой насоса. Обратна св зь от наклонной шайбы к гидрораснределителю 19 осуществл етс через рычаги 26 и 20. Взаимодействие рычага переключени скоростей с трехлинейным двухнозиционным гидрораспределителем 8 фрикционного тормоза осуществл етс через рычаг 27. На фиг. 3-5 нейтральное положение рычага 4 обозначено сплощлыми лини ми, а положени 4, 4 и 4 соответствующие максИМальной передней скорости, ма1ксимальной задней и включению тормоза, соответс-лвенно обоз,начены штрих-пунктирными лини ми. Подвод рабочей жидкости iK распределителю 8 .производитс ,в отверстие 28.The speed control of the hydrostatic transmission is carried out in a known manner with the ram of a throttling valve 19, the spool of which is connected to the speed selector lever 4 through the levers 20-23 and traction 23. The outlet hydraulic lines of the distributor are connected to the cavities of the hydraulic cylinder 24, the brush 25 of which is hinged to the inclined face of the pump. The feedback from the inclined washer to the hydraulic distributor 19 is carried out through levers 26 and 20. The interaction of the speed selector lever with the three-line dual-valve hydraulic distributor 8 of the friction brake is carried out through the lever 27. In FIG. 3-5, the neutral position of the lever 4 is indicated by flat lines, and the positions 4, 4 and 4 corresponding to the maximum front speed, the maximum rear speed and the brake on, respectively, are worn with dash-dotted lines. The supply of the working fluid iK to the distributor 8 is produced in the hole 28.
При работе, когда требуетс затормозить выходной вал гидростатической передачи, необходимо передвинуть рычаг 4 в .положение . При этом рычаг сначала выводитс в нейтральное положение. Это вызывает перемещение золотника гидрораопределител 19 через т гу 23 и рычаги 22, 21 vi 20, а вслед за ним штока 25 гидроцилиндра 24 и наклонной шайбы 14 насоса 15 в положение нулевой скорости насоса.In operation, when it is necessary to brake the output shaft of a hydrostatic transmission, it is necessary to move lever 4 to the position. In this case, the lever is first brought to the neutral position. This causes the hydraulic defining spool 19 to move through t gu 23 and levers 22, 21 vi 20, followed by the stem 25 of the hydraulic cylinder 24 and the inclined washer 14 of the pump 15 to the zero speed position of the pump.
При достижении .наклонной шайбой положени нулевой скорости насоса ролик 13 закрепленного на ней запирающего рычага 12 попадает в выемку 17, а толкатель 10 коромысла 16 и механизм баскировки .переход т в свою открытую позицию.When the inclined washer reaches the zero speed of the pump, the roller 13 attached to it the locking lever 12 enters the recess 17, and the pusher 10 of the rocker arm 16 and the skid mechanism move to its open position.
Дальнейщее перемещение рычага 4 в положе1ние 4 передаетс через ,рычаг 27 на золотиик гидрораснределител 5, в результате чего открываетс доступ рабочей жидкости к гидродвигателю 7 фрикционного тормоза 5 и происходит торможение выходного вала 6 гидростатического привода /.The further movement of the lever 4 to the position 4 is transmitted through the lever 27 to the gold distributor 5, as a result of which the working fluid opens to the hydraulic motor 7 of the friction brake 5 and the output shaft 6 is braked.
При перемещении рычага 4 в положени передней или задней скорости гидрораспределитель 8 автО|Матически выводитс в позицию, при которой гидролини // соедин етс со сливоМ. Выведение наклонной шайбы насоса из ноложени нулевой скорости вызывает перемещение ролика 13 из выемки 17 и, как следствие, толкател 10 из выемки 18 коромысла - механизм блокировки переходит в закрытую лозицию, исключающую попадание рабочей л идкости к гидродвигателю .When the lever 4 is moved to the front or rear speed position, the hydraulic distributor 8 auto-matic is brought to the position at which the hydrolines // are connected to the drain. Removing the inclined pump washer from the zero speed position causes the roller 13 to move out of the recess 17 and, as a result, the pusher 10 out of the rocker notch 18 - the locking mechanism goes into a closed position that prevents the working fluid from entering the hydraulic motor.
