An axle center transmission for transmitting a driving torque received from a drive device to two half shafts of an axle of a vehicle comprises a transmission gearing for transmitting a driving torquereceived at an input element and having at least two selectively switchable gear transmission ratios and a differential for distributing the transmitted driving torque to two output elements. The transmission gearing has a first gear that is formed as a planetary transmission and comprises a first sun gear, a first planet carrier having one or more planet gears, and a first annulus gear. The transmission gearing furthermore has a second gear that is formed as a planetary transmission and comprises a second sun gear, a second planet carrier having one or more planet gears, and a second annulusgear. The first sun gear forms said input element; the first planet carrier is stationary; and the second sun gear is couplable or coupled to the first annulus gear for a common rotation.
用于将从驱动设备接收到的驱动力矩传递至交通工具的轴的两个半轴的轴中心传动装置包括变速传动机构以及差速器,变速传动机构用于使在输入元件上接收的驱动力矩以至少两个可选择切换的传动比进行变速,所述差速器用于将变速后的驱动力矩分配至两个输出元件。变速传动机构具有第一传动级,其构造为行星传动机构并且包括第一太阳轮、带有一个或多个行星轮的第一行星架以及第一空心轮。变速传动机构具有第二传动级,其构造为行星传动机构并且包括第二太阳轮、带有一个或多个行星轮的第一行星架以及第二空心轮。第一太阳轮构成输入元件,第一行星架是固定的,并且第二太阳轮与第一空心轮能够耦合或与第一空心轮耦合,以便共同旋转。
