    Multi-ratio epicyclic change-speed gearing comprises at least three epicyclic gear trains or gear sets, with the planet carrier of the first gear set rotationally secured to the ring gear of the second gear set and an input is connected to the sun gear of the first gear set. Means are provided for holding the ring gear of the first gear set and/or the sun gear of the second gear set against driving reactions. The ring gear of the third gear set is rotationally secured to the planet carrier of the second gear set, the planet carrier of the third gear set is rotationally secured to the sun gear of the second gear set and further holding means are provided for holding the sun gear of the third gear set. As a result, the lower ratios are more widely spaced than the ratios nearer unity.

    54) PLANETARY GEARBOX
    The invention relates to mechanical engineering and can be used as a planetary gearbox in various vehicles. A planetary gearbox is known, containing input and output shafts, two controllable clutches, two controllable brakes and two planetary rows, including each sun gear, carrier with satellites and an epicyclic, in which the sun gears of both rows are connected between through one of the coupling couplings connected to the input shaft, the carrier of the first row is connected with one of the brakes and through the other coupling coupling connected with the input shaft, the epicicle of the second row is connected with another brake, and the carrier of the same row is connected with the epicyclic first of all And with the output shaft 1. The disadvantages of this gearbox are the impossibility of obtaining a number of gear ratios of more than four. The closest in technical essence to the present invention is a planetary gearbox containing input and output shafts, two controllable clutches, three controllable brakes and three planetary rows, including each sun gear, drove with satellites and epicycles. In this gearbox, the input shaft is connected to the sun gear of the first row, the carrier of which is connected to the second row epicycle, and also associated with the first brake and the first coupling coupling blocking this carrier 6 with the input shaft, the first row epicycle The second coupling is connected to the second row carrier connected to the output shaft, the sun gear of the second row is connected to the third row carrier and the second brake, and the third gear is connected to the third brake. This gearbox provides eight gear ratios t23 The disadvantages of the well-known gearbox are that the choice of gear ratios required in several cases is limited by the kinematic characteristics of the gearbox. In particular, seven forward gear ratios are not obtained.
    The purpose of the invention is to improve the distribution of gear ratios.
    The goal is achieved by connecting the input shaft through the first coupling to the sun gear of the first row, the carrier of the same row connected to the output shaft and the epicycle of the second row, the epicycle of the first row connected to the first brake and connected to the carrier second, third row and epicycle, the sun gear of which is connected to the second brake, and the third p Jga carrier is connected to the third brake, second row gear with the sun gear and connected to the input shaft through the second coupling clutch.
    The planetary gearbox is additionally equipped with a third controlled clutch and a free wheel mechanism, which connect the input shaft with the carrier of the second and third rows, respectively.
    The planetary gearbox is additionally equipped with a fourth controlled brake and a fourth planetary series, the sun gear and epicycle are connected respectively to: a sun gear and a carrier of the first row, an epicycle also connected to the fourth brake, and drove
    with output shaft.
     FIG. Figure 1 shows the kinematic diagram of the planetary gear structure; in fig. 2 is a kinematic diagram of one of the possible embodiments of a planetary gearbox with one additional planetary gear set next to FIG. 3 - the kinematics of one scheme of another variant of the implementation of a planetary gearbox with two additional planetary rows.
    A planetary gearbox (fig. Contains an input shaft 1, an output shaft 2, three controlled coupling sleeves 3-5, three controlled brakes 6-8 a free-running mechanism 9, the first planetary gear set including the sun gear 10, drove 11 with satellites and epicyclic 12, the second planetary row including sun gear 13, drove 14 with satellites and epicycl 15, the third planetary row including sun gear 16, drove 17 with satellites and epicycl 17. drove, 11 is connected to the output shaft 2 and the epi cycle 15, epicycle 12 is associated with brake 8 and is connected to carrier 14 and epi 18, sun gear 16 is connected to brake 7, carrier 17 is connected with brake 6, connected to sun gear 16 and connected via input mechanism 9 to input shaft. 1, carrier 14, carrier 17 and sun gear 10 through coupling The couplings 5, 4 and 3, respectively, are connected to the input shaft 1.
    Planetary gearbox works as follows.
    With the inclusion of two controls, the links of the planetary rows are connected and a certain kinematic scheme, which provides the appropriate gear ratio.
    So, for example, when the ratio of the numbers of teeth of an epicycle and sun gear of the first stage is K 84/28, and of the second and third stages K K, 78/36, the resulting gear ratios and the included controllable elements are shown in Table. one.
    The presence of a free-running mechanism 9 in the circuit ensures a smooth transition from direct transmission to any accelerating transmission when the clutch 5 is engaged.
    If it is necessary to have a greater number of transmission ratios, a planetary gearbox (Fig. 1 may have additional planetary rows and controllable elements. Table 1
    In the embodiment shown in Fig. 2, the gearbox has an additional brake 19, an additional controlled clutch 20, connected by an epicyclic 15 to the input shaft 1, and an additional planetary row, the carrier 21 of which is connected to the output shaft 2, the epicycle 22 is connected With the torus variant shown in FIG. 3 gears with respect to the R variant shown in figure 2, an additional brake 24 and. an additional planetary row, the carrier 25 of which is associated with the brake 24, the epicycle 26 is connected to the output shaft 2, and the sun gear 27 is connected to the epicycle 22.
    In this version, the gearbox has additional, including very low, transfer ratios of forward travel, for example, 9.25: 1 (.when switching on 3 and 26) and 13-36: 1. (at inclusion 4 and 26), and also additional transfers of a backing.
    The proposed implementation of the planetary gearbox allows to obtain low gear ratios with relatively wide intervals relative to each other and at the same time have a number of gear ratios close to, with relatively short intervals between
    19 and is connected to the carrier 11, and the sun gear 23 is connected to the sun gear 10.
    When the ratio of the number of teeth of the epi cycle 22 and the sun gear 23 equal to 84/28 and the same values of K, K can be obtained transfer ratios, indicated in table 2,
    themselves tending to narrow as the gear ratios approach one.
    The specified distribution of gear ratios increases the efficiency of the gearbox when the vehicle is moving at speeds close to cruising.
