A work vehicle multi-speed drive assembly with a clutch retention mechanism is provided having: a drive housing including at least one housing part forming a reaction member; a drive shaft rotatable about a drive axis; and a planetary gear set coupled to the drive shaft and configured to selectively rotate the output member. The drive assembly also includes at least one clutch device having at least one clutch ring configured to selectively interact with the planetary gear set to achieve a rotational speed of the output member. The at least one actuator is configured to axially drive the clutch ring along the drive axis. The retention mechanism is configured to retain the clutch ring at an axial position along the drive axis. The retaining mechanism comprises a positioning ball, a positioning groove and an elastic component, and the elastic component is configured to push the positioning ball into the positioning groove so as to retain the clutch ring at the axial position.

    提供了一种具有离合器保持机构的作业车辆多速驱动总成,其具有:包括形成反作用构件的至少一个壳体部件的驱动壳体;可绕驱动轴线旋转的驱动轴;以及行星齿轮组,该行星齿轮组被联接至驱动轴并且该行星齿轮组被配置成选择性地使输出部件旋转。该驱动总成还包括至少一个离合器装置,所述至少一个离合器装置具有至少一个离合器环,所述至少一个离合器环被配置成选择性地与行星齿轮组相互作用以实现输出部件的转速。至少一个致动器被配置成沿着驱动轴线轴向地驱动离合器环。保持机构被配置成将离合器环保持在沿着驱动轴线的轴向位置处。该保持机构包括定位球、定位槽及弹性构件,该弹性构件被配置成将定位球推入定位槽中以将离合器环保持在轴向位置处。
