A work vehicle multi-speed drive assembly providing multiple gear ratios at the same order ratio is provided. The drive assembly includes a housing arrangement, a drive shaft rotatable in a first clock direction and a second clock direction, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes or is coupled to an output member. The first clutch device and the second clutch device are configured to selectively engage the gear set to achieve a first gear ratio and a second gear ratio, respectively. The order ratio from the first transmission ratio to the second transmission ratio is 3: 1. The at least one first actuator and the at least one second actuator are configured to effect movement of the first clutch device and the second clutch device, respectively, to selectively engage the gear set. The driveshaft and the output member rotate in the same clock direction with the first clutch device engaged with the gear set and in the opposite clock direction with the second clutch device engaged with the gear set.
提供了以相同阶比来提供多个传动比的作业车辆多速驱动总成,该驱动总成包括:壳体装置、可沿第一时钟方向和第二时钟方向旋转的驱动轴、以及联接至驱动轴的两级行星齿轮组。该齿轮组包括或者联接至输出部件。将第一离合器装置和第二离合器装置配置成,选择性地接合齿轮组,以分别实现第一传动比和第二传动比。从第一传动比到第二传动比的阶比为3:1。将至少一个第一致动器和至少一个第二致动器配置成,分别实现第一离合器装置和第二离合器装置的移动,以选择性地接合齿轮组。驱动轴和输出部件在第一离合器装置与齿轮组接合的情况下沿相同的时钟方向旋转,并且在第二离合器装置与齿轮组接合的情况下沿相反的时钟方向旋转。
