Description

(54) ПЛАНЕТАРНАЯ КОРОБКА ПЕРЕДАЧ(54) PLANETARY GEARBOX

Водило 3 св зано с тормозом 5 и через блокирующий фрикцион 6 с ведущим валом 1.The carrier 3 is connected with the brake 5 and through the blocking friction clutch 6 with the drive shaft 1.

Эпицикл 7 жестко соединен с эпициклом 8 третьего планетарного р да и с блокирующим фрикционом 9, расположенным вне вращающихс  тормозных барабанов. Водило 10 второго планетарного р да св зано с блокируюЩИм фрикционом 9 и жестко соединено с ведомым валом 11.The epicyclic 7 is rigidly connected to the epicycle 8 of the third planetary row and to the blocking friction 9 located outside the rotating brake drums. The carrier 10 of the second planetary row is connected with the locking friction clutch 9 and is rigidly connected with the driven shaft 11.

Солнечна  шестерн  12 второго планетарного р да жестко соединена с водилом 13 третьего планетарного р да и со вторым тормозом 14. Солнечна  шестерн  15 третьего планетарного р да жестко соединена с третьим тормозом 16. Солнечные щестерни 2, 12 и 15 соединены с соответствующими эпициклами 7, 4 и 8 через сателлиты 17, 18 и 19.The sun gear 12 of the second planetary row is rigidly connected to the carrier 13 of the third planetary row and with the second brake 14. The sun gear 15 of the third planetary row is rigidly connected to the third brake 16. The sun shanks 2, 12 and 15 are connected to the corresponding epicycles 7, 4 and 8 through satellites 17, 18 and 19.

Коробка передач работает следующим образом .Transmission works as follows.

ПрИ включении двух элементов управлени  звень  планетарных механизмов соедин ютс  в определенную схему, и реализуетс  соответствующий режим работы планетарной коробки передач. Возможны всего дес ть вариантов включени , но одновременно нельз  включать элементы 5 и 6. Таким образом из дес ти вариантов включени  можно использовать только дев ть, что соответствует дев ти различным режимам работы коробки передач.When two control elements are turned on, the links of the planetary mechanisms are connected to a specific circuit, and the corresponding mode of operation of the planetary gearbox is realized. Only ten switching options are possible, but it is impossible to include elements 5 and 6 at the same time. Thus, out of ten switching options, only nine can be used, which corresponds to nine different modes of transmission operation.

Передаточные числа, реализуемые в предлагаемой коробке передач, определ ютс  следующими выражени ми и  вл ютс  функцией параметровGear ratios implemented in the proposed transmission are defined by the following expressions and are a function of the parameters
