According to the power gear shifting gearbox and the tractor, when one first gear shifting clutch in a main speed changing device is combined with one corresponding first gear pair, other first gear shifting clutches are disconnected with the corresponding first gear pairs, so that gear shifting is carried out by selecting one of the first gear shifting clutches to be combined; it is guaranteed that power is not interrupted in the gear shifting process; when one second gear shifting clutch in the auxiliary speed change device is combined with one corresponding second gear pair, other second gear shifting clutches are disconnected with the corresponding second gear pairs, so that ring gear shifting is carried out through selective combination of the second gear shifting clutches, and it is guaranteed that power is not interrupted in the gear shifting process. Therefore, according to the power gear shifting gearbox, multi-gear switching can be achieved under the condition that power is not interrupted, and the working efficiency can be improved.

    本发明提供一种动力换挡变速箱和拖拉机,由于主变速装置中一个第一换挡离合器与对应的一个第一齿轮副结合时,其他的第一换挡离合器与各自对应的第一齿轮副断开,以通过各第一换挡离合器的择一结合来进行换挡,并保证在换挡过程中动力不中断;副变速装置中一个第二换挡离合器与对应的一个第二齿轮副结合时,其他的第二换挡离合器与各自对应的第二齿轮副断开,以通过各第二换挡离合器的择一结合来进行环换挡,并保证在换挡过程中动力不中断。因此,本实施例的动力换挡变速箱能够实现在不中断动力情况下进行多挡位切换,有利于提高作业效率。
