摘要： A power train for a machine is provided having a transmission including a plurality of gears configured to produce multiple output ratios when selectively engaged. The power train also has at least one sensor configured to sense at least one parameter indicative of a condition requiring a disablement of a gear output ratio during a downshifting event. In addition, the power train has a controller configured to regulate the transmission in either a first or a second mode in response to the at least one parameter. At least one of the gear output ratios is disabled during downshifting events occurring while the controller regulates the transmission in the first mode. Furthermore, all gear output ratios are available during downshifting events occurring while the controller regulates the transmission in the second mode.

摘要： A multi-speed transmission (100) employs an efficient number of components to provide at least nine forward gear ratios and at least two reverse gear ratios between an input member (16) and an output member (20) disposed in a housing (14). The transmission may employ four planetary gear sets (30, 32, 34, 36). Each planetary gear set may include a sun gear (38/44/50/56), a planet carrier (40/46/52/58), and a ring gear (42/48/54/60). Six control elements (62/64/66/68/70/72) may be operably coupled to the planetary gear sets and selectively engageable to create the forward and reverse gear ratios.
摘要翻译：多速变速器（100）使用有效数量的部件来在设置在壳体（14）中的输入构件（16）和输出构件（20）之间提供至少九个前进档比和至少两个倒档比，。变速器可以采用四个行星齿轮组（30,32,34,36）。每个行星齿轮组可包括太阳轮（38/44/50/56），行星架（40/46/52/58）和环形齿轮（42/48/54/60）。六个控制元件（62/64/66/68/70/72）可以可操作地联接到行星齿轮组，并且可选择性地接合以产生前进和后退传动比。

摘要： A gearbox (1) having at least two gears is disclosed. The gearbox may include a first gearshaft (3), a second gearshaft (4) selectively engagable with the first gearshaft via the at least two gears, and at least one clutch mechanism (8, 9) located on the second gearshaft and configured to selectively engage the first gearshaft with the second gearshaft. The clutch mechanism may include a synchronizer (10), at least one clutch plate (12) attached to a gear (5b, 6b) on the second gearshaft, and a pressure plate (13) associated with the synchronizer. The clutch plate and the pressure plate may be configured to selectively engage one another, and the synchronizer may be configured to drivingly engage the second gearshaft so that the second gearshaft is driven by the first gearshaft.
