The invention discloses a transmission of a vehicle, a power system and the vehicle. The transmission of the vehicle comprises a shell, an isolation plate is arranged in the shell, a driving cavity is formed in one side of the isolation plate, and a power generation cavity is formed in the other side of the isolation plate; the one-way oil duct is used for guiding oil to the power generation cavity from the driving cavity in a one-way mode; and the oil drainage mechanism is used for draining the oil liquid in the power generation cavity to the driving cavity when the oil liquid in the power generation cavity exceeds the preset set amount. Therefore, the isolation plate divides the interior of the shell into the power generation cavity and the driving cavity which are used for independently storing oil liquid, the one-way oil channel guides the oil liquid in the driving cavity into the power generation cavity in a one-way mode, in this way, when the transmission inclines, the power generation cavity still has sufficient oil liquid to lubricate internal parts, and the reliability of the transmission can be guaranteed. In addition, when the oil in the power generation cavity exceeds the preset set amount, the oil drainage mechanism drains the oil to the driving cavity, excessive oil in the power generation cavity is prevented, and therefore the oil stirring loss of components in the power generation cavity can be reduced.
本发明公开了一种车辆的变速器、动力系统和车辆,车辆的变速器包括:壳体,壳体内设有隔离板,隔离板的一侧设有驱动腔,隔离板的另一侧设有发电腔;单向油道,单向油道用于驱动腔向发电腔单向导油;泄油机构,泄油机构用于在发电腔内油液超过预设设定量时,将发电腔内的油液泄放至驱动腔。由此,隔离板将壳体内部分隔成独立存储油液的发电腔和驱动腔,单向油道将驱动腔中的油液单向导入发电腔中,如此,变速器倾斜时,发电腔仍然有充足的油液对内部部件润滑,可以保证变速器的可靠性。另外,发电腔中的油液超过预设设定量时,泄油机构将油液泄放至驱动腔,防止发电腔中油液过多,这样可以减少发电腔中部件的搅油损失。
