The invention relates to a transmission for a drive train of a motor vehicle, comprising: a crown gear assembly (4), which has a first crown gear (19), which can be rotationally driven about an axis of rotation (B) by a drive source, a second crown gear (20), which is rotatably arranged coaxial to the first crown gear (19), a plurality of cylindrical gears (22), which are in tooth engagement withthe first crown gear (19) and the second crown gear (20), and a carrier element (23), on which the cylindrical gears (22) are rotatably mounted and which can be rotationally driven about the axis of rotation (B) in order to transfer torque to a downstream drive unit (9); a first clutch (43) for selectively connecting the second crown gear (20) to a stationary component (17) with respect to driving; and a second clutch (44) for selectively connecting two of the three elements (19, 20, 23) of the crown gear assembly (4) with respect to driving; wherein a first transmission ratio (i1) and a second transmission ratio (i2) between the first crown gear (19) and the carrier element (23) can be set by switching the first and the second clutches (43, 44) accordingly.
本发明涉及一种用于机动车的传动系的换挡变速器,所述换挡变速器包括:冠状齿轮装置(4),所述冠状齿轮装置具有能够由驱动源围绕着旋转轴线(B)旋转地驱动的第一冠状齿轮(19)、以能够与所述第一冠状齿轮(19)同轴地旋转的方式布置的第二冠状齿轮(20)、多个与所述第一冠状齿轮(19)和所述第二冠状齿轮(20)处于啮合之中的正齿轮(22)以及基座元件(23),所述正齿轮(22)以能旋转的方式在所述基座元件(23)上得到支承并且所述基座元件(23)能够围绕所述旋转轴线(B)旋转地驱动,以便将转矩传递到布置在后面的驱动单元(9)上;第一离合器(43),所述第一离合器用于选择性地在驱动方面将所述第二冠状齿轮(20)与位置固定的构件(17)连接起来;和第二离合器(44),所述第二离合器用于选择性地在驱动方面将所述冠状齿轮装置(4)的三个元件(19、20、23)中的两个元件连接起来,其中通过所述第一和第二离合器(43、44)的相应的切换能够设定所述第一冠状齿轮(19)和所述基座元件(23)之间的第一传动比(i1)和第二传动比(i2)。
