    The invention relates to mechanical engineering and can be used as a transmission in various machines and mainly in machines such as loaders having approximately the same number of front and rear gears. A planetary gearbox is known, containing input and output shafts, two controllable clutches, three controllable brakes and three planetary rows, each of which includes a solar bristle, a carrier with installed satellite satellites and epicycles. gears, the main links of the planetary rows are kinematically connected with each other, with controlled elements and with input and output shafts. The box provides six forward and two reverse gears as well as the possibility of rotation of the input shaft with the output va .le 1. A disadvantage of the known gearbox is the prevailing number of forward gears, which is not acceptable for loaders. The closest to the technical essence of the invention is a planetary gearbox, containing input and output balls, a controlled clutch, four controllable mosaic torches and four planetary gear mechanisms, including each drove with installed satellite on the axles and the sun gear and epicycle, which borrow from the latter, of which the sun gear of the first planetary mechanism is connected to the first brake and connected to the input shaft through the clutch, drove the first planetary mechanism to the epicyclic The second planetary mechanism and the second brake, the epicyclic of the first planetary mechanism is connected to the planet carrier of the second planetary mechanism connected to the output shaft 23 In said box, the sun gear of the second planetary mechanism is connected to the input shaft, the link of the third planetary mechanism is connected as follows: with the epicyclic of the second planetary mechanism, drove with the third brake and with the carrier of the fourth planetary mechanism, the epicycle with the carrier of the fourth planetary mechanism and with input a single shaft, and the epicyclic of the fourth planetary mechanism is associated with the fourth brake. The disadvantages of this gearbox are a small number of gears, a total of four, of which three are forward and one reverse. The purpose of the invention is to increase the number of gears with an approximate equality of the values of gear ratios of forward and reverse. This goal is achieved by the fact that the planetary gearbox contains input and output shafts, a controlled clutch, four controlled brakes and four planetary gear mechanisms, each of which includes a carrier with satellites installed on it on the axles and interacting with the latest sun gear and the epicycle, of which the sun gear of the first planetary mechanism is connected to the first brake and connected to the input shaft through the clutch, drove the first planetary mechanism to the epicycle of the second planetary mechanism The mechanism and the second brake. The epicyclic of the first planetary mechanism is connected to the carrier of the second planetary mechanism connected to the output shaft. It is equipped with an additional controlled coupling connecting the sun gear of the second planetary mechanism to the input shaft. The epicycle of the second and third planetary mechanisms are interconnected. , drove the third planetary mechanism connected with the third brake and connected to the epicycle of the fourth planetary mechanism; drove the same planetary mechanism connected with the fourth Ormoz, and sun gears of the third and fourth planetarngh mechanisms are connected to the output shaft. The drawing shows the kinematic scheme of the proposed transmission. The planetary gearbox contains input 1 and output 2 shafts, controllable ZIL clutches, controllable brakes 5-8, four planetary mechanisms, including: sun gear 9, carrier 10 with satellites and epicycle 11 of the first planetary mechanism, sun gear 12, carrier 31 13 with satellites and epicycle 1A second planetary gear, sun gear 15, drove 16 with satellites and epicyc 17 third planetary gear, sun gear 18, drove 19 with satellites and epicycl 20 fourth planetary gear. The sun gear 9 is connected to the brake 5 and is connected via coupling 4 to the input shaft 1, the carrier 10 is connected to epicycles 14 and 17 and connected with brake 6, the epicycle 11 is connected to the carrier 13 and the output shaft 2, the carrier 16 is connected to the epicycle 20 and associated with brake 7; carrier 19 associated with brake 8; sun gears 15 and 18 are connected to output shaft 2. The transmission operates as follows. When the input shaft 1 rotates and the respective clutches and brakes are paired, the rotation along the kinematic chain is transmitted to the output shaft 2. Depending on the engagement of certain clutches and brakes, a transmission with a certain gear ratio is realized. So, for example, in a gearbox with internal ratios of planetary mechanisms 1–4, respectively equal to: K - and K - 51 k 36 3 4B -4-48, eight gear ratios are obtained, which are also shown in the table, where which controllable elements (clutches and brakes) are included. 5 Transmission of the front gear of the rear -6.65 -3.49 -1.857 Enhancement of the gearbox according to the invention doubles the total number of gears compared to the known gearbox and allows you to get a number of gears of forward and reverse gears, which is especially useful for loaders and other transport machines, the so-called shuttle type.
