(54) ГИДРОМЕХАНИЧЕСКИЙ ПРИВОД САМОХОДНОЙ МАШИНЫ(54) HYDROMECHANICAL DRIVE OF SELF-PROPELLED MACHINE

12 и 13 выходного вала 14 подвижно усановлена- муфта It) диапазонного ре.цук-1ч ра трансмиссии.« 12 and 13 of the output shaft 14 is movably mounted — the clutch It) of the range re.tsuk-1h ra transmission. “

На валу гидромотора 9 установлена подвижна шестерн 17, Она находитс в посто нном зацеплении с шестерней 18 и входит или выходит из зацеплега с шестерней 11, Шестерн 18 свободно установ лена на валу отбора мощности 19. На валу 19 подвижно установлена мус1)та 20, выборочно соедин юща вал 19 с и естерней 18 и дополнительным валом 21. Вал 21 св зан с валом 1 двигател 2 через шестерни 22 и 4.A movable gear 17 is mounted on the shaft of the hydraulic motor 9, It is permanently engaged with the gear 18 and enters or leaves the hook gear with the gear 11, The gear 18 is freely mounted on the power take-off shaft 19. The shaft 19 is movably mounted a connecting shaft 19 s and a spindle 18 and an additional shaft 21. The shaft 21 is connected to the shaft 1 of the engine 2 via gears 22 and 4.

Мощность от двигател 2 передаетс посто нно к выходному валу 14 через вал 1, шестерни 4 и 3, насос 6 и гидромотор 8 гидропередачи, шестерни 10, 12 или 12, 13 диапазонного редуктора привода ходовой части. Отключение шестерен 12 и 13 от выходного вала 14 может быть использовано дл режимов движени на буксире и дл передачи всей мощности двигател к валу отбора мошности 19.Power from engine 2 is transmitted continuously to output shaft 14 through shaft 1, gears 4 and 3, pump 6 and hydraulic transmission motor 8, gears 10, 12 or 12, 13 of the range drive gearbox reducer. The disengagement of gears 12 and 13 from the output shaft 14 can be used for driving modes in tow and for transferring all engine power to the power take-off shaft 19.

В режиме работы самоходной машины с большими т говыми усили ми дл предотвращени повышени давлени в гидро- системе гидромотор 9 через шестерни 17 и 11 также подключен к выходному валу 14.In the mode of operation of the self-propelled machine with large tractive effort to prevent the increase in pressure in the hydraulic system, the hydraulic motor 9 through gears 17 and 11 is also connected to the output shaft 14.

Вал отбора мошности 19 имеет три режима работы.Shaft selection power 19 has three modes of operation.

Первый режим работы - синхронный со скоростью трактора режим. Мощность от двигател 2 передаетс чере насосы 6 и 7 к гидромоторам В и 9, в«шы которых соединены ерез шестерни 17 и 11, а с выходным вачом 14 и с валом отбора мощности 19 через шестерни 17, 18 и муфту 2О. Режим используетс при работе трактора в агрегате с посадочными и посевны.ми машинами и разбрасывател ми удобреНИИ .The first mode of operation is synchronous with the speed of the tractor. The power from the engine 2 is transmitted through pumps 6 and 7 to hydraulic motors B and 9, in which they are connected via gears 17 and 11, and to output vacuum 14 and to power take-off shaft 19 via gears 17, 18 and coupling 2O. The mode is used when the tractor operates in an aggregate with planting and sowing machines and fertilizer spreaders.

Во втором режиме работы гидро ;тати- ческий регулируемый привод не зависит . от скорости движени трактора. Подвижна шестерн 17 выведена из зацеплени с шестерней 11, но продолжает рахолитъс в зацеплении с шестерней 18.In the second mode of operation, the hydrostatic controlled drive is independent. from the speed of the tractor. The movable gear 17 is disengaged from gear 11, but continues to be engaged in meshing with gear 18.

Мощность от двигател 2. передаетс на вал отбора мощности через насос 7,The power from the engine 2. is transmitted to the power shaft through pump 7,

гидромотор 9, шестерни 17, 18 и подвижную муфту 20.hydraulic motor 9, gears 17, 18 and movable clutch 20.

Регулируемый насос обеспечивает настройку CKopocTHTjix режимов рабочих органов агрегатируемых машин, не передающих на Ti-iaKTOp больших т говых усилий (почвенные фрезы, роторные культиваторы i- дрAn adjustable pump provides for setting up the CKopocTHTjix modes of the working bodies of the aggregated machines that do not transfer large tractive forces to the Ti-iKTOp (soil cutters, rotary cultivators i- others

В третьем режиме работы привод от вала двигател не зависит от скорости движени трактора. Самоходна машина работает в режиме больших т говых усилий ,In the third mode of operation, the drive from the engine shaft does not depend on the speed of the tractor. Self-propelled machine operates in high traction mode,

Оба гидромотора передают мощность к ведущим колесам (куестерни 17 и 11 соединены ). Подвижна MycttTa 2 О соедин ет вал 19 и дополнительный в л 21.Both hydromotors transmit power to the drive wheels (the quicksters 17 and 11 are connected). Movable MycttTa 2 O connects shaft 19 and optional in l 21.

Режим используетс щэи работе трактора в агрегате с корнеклубнеуборочными комбайнами и на совмегаенных с пахотой опера 1ШЯХ.The mode is used for tractor operation in an aggregate with root-harvesting combines and combined with plowed opera 1SH.

Claims
