(54) ПЛАНЕТАРНАЯ КОРОБКА ПЕРЕДАЧ(54) PLANETARY GEARBOX
Изобретение относитс к машиностроению и может быть использовано в трансмисси х транспортных и сельскохоз йственных машин. По основному авт.св. № 905548 известна планетарна коробка передач, содержаща входной и выходной валы, две управл емые сцепные муфты, четыре управл емых тормоза и два планетарных р да, первый из которых вклюп чает водило с двухвенцовыми сателли тами, солнечную шестерню, эпицикл и центральное колесо, а второй - водило с одновенцовыми сателлитами, солнечную шестерню и эпицикл,солнеч на-л шестерн первого р да соединена с входным валом и через первую сцепную муфту с солнечной шестерней второго р да, котора св зана с первым тормозом, водило первого р да соединено с эпициклом второго р да и св зано с вторым тормозом, эпицикл первого р да св зан с третьим тормозом и через вторую сцепную муфту соединен с водилом второго р да, которое соединено с выходным валом, а центральное колесо первого.р да св зано с четвертым тормозом. Эта коробка передач при попарном включении управл емых элементов, т.е сцепных муфт и тормозов, обеспечивает получение дев ти передач, из которых семь передач пр мого хода, а две - заднего хода 1. К недостаткам этой коробки передач относитс невозможность получени числа передач более дев ти. Целью изобретени вл етс расширение кинематических возможностей коробки передач, т.е. увеличение числа возможных передач. Эта цель достигаетс тем, что коробка передач снабжена взаимодействующим с соответствующими венцами двухвенцовых сателлитов дополнительным центральным колесом и св занным с ним п тым управл емым тормозом. На чертеже изображена кинематическа схема планетарной коробки передач . Планетарна коробка передач содержит входной 1 и выходной 2 валы, две управл емые сцепные муфты 3 и 4, п ть управл емых тормозов 5-9, первый планетарный р д, включающий солнечную шестерню 10, эпицикл 11, водило 12 с двухвенцовыми сателлитами 13, основное 14 и дополнительное 15 центральные колеса, второй планетарный р д, включающий солнечную шестсрню 16, водило 17 с одновенцовыми сателлитами 18 и эпицикл 19. Солнечна шестерн 10 соединена с входным валом 1 и через сцепную муфту 4 с солнечной шестерней 16,св занной с тормозом 8, водило 12 соединено с эпициклом 19 и св зано с тормозом 5, эпицикл 11 св зан с тормозом 7 и через сцепную муфту 3 соединен с водилом 17, которое соединено с выходным валом 2, основное центральное колесо 14 св зано с тормозом 6, а дополнительное центральное колесо 15 - с тормоз ом 9.The invention relates to mechanical engineering and can be used in transmissions of transport and agricultural machines. According to the main auth. No. 905548 is known for the planetary gearbox, which contains input and output shafts, two controllable clutches, four controllable brakes and two planetary rows, the first of which includes a two-wheel satellite carrier, a sun gear, an epicycle and a central wheel, and the second - drove with single-pin satellites, sun gear and epicycle, sun n-l gear of the first row is connected with the input shaft and through the first coupling coupling with the sun gear of the second row, which is connected with the first brake, drove the first row of joint but with the second row epicycle and associated with the second brake, the first row epicycle connected with the third brake and connected via a second clutch to the second row carrier, which is connected to the output shaft, and the central wheel of the first. fourth brake. This gearbox, with the pairwise engagement of controlled elements, i.e. clutch couplings and brakes, provides nine gears, of which seven gears are forward and two reverse gears. The disadvantages of this gearbox are the impossibility of getting more gears nine. The aim of the invention is to expand the kinematic capabilities of the gearbox, i.e. increase in the number of possible gears. This goal is achieved by the fact that the gearbox is equipped with an additional central wheel interacting with the corresponding rims of the two-crown satellites and a fifth controlled brake connected with it. The drawing shows a kinematic diagram of the planetary gearbox. The planetary gearbox contains input 1 and output 2 shafts, two controllable coupling sleeves 3 and 4, five controllable brakes 5-9, the first planetary series, including sun gear 10, epicycle 11, drove 12 with two-satellite satellites 13, the main 14 and an additional 15 central wheels, a second planetary row, including the sun gear 16, drove 17 with single-pin satellites 18 and an epicycle 19. The sun gear 10 is connected to the input shaft 1 and through the clutch 4 to the sun gear 16 connected to the brake 8 drove 12 connected to epicyclic ohm 19 and connected to brake 5, epicyclic 11 connected to brake 7 and through coupling coupling 3 connected to carrier 17, which is connected to output shaft 2, main central wheel 14 connected to brake 6, and additional central wheel 15 to c brake ohm 9.
Коробка передач работает следующим образом.Transmission works as follows.
При попарном включении управл емых сцепных муфт и тормозов звень планетарных р дов соедин ютс в определенную кинематическую схему, и вращение от входного вала 1 к выходному валу 2 передаетс с соответствующим этой схеме передаточным отношением .When the controlled coupling clutches and brakes are connected in pairs, the links of the planetary rows are connected to a specific kinematic scheme, and the rotation from the input shaft 1 to the output shaft 2 is transmitted with the gear ratio corresponding to this scheme.
Передачи переднего хода в пор дке их возрастани реализуютс при включении следующих пар элементов управлени : би8, 4и9, 7и8, 4Forward gears, in the order of their increase, are realized with the inclusion of the following pairs of control elements: bi8, 4i9, 7i8, 4
