具有主齿轮箱和动力输出单元的变速器
摘要：
变速器(1)，其包括主齿轮箱(2)和动力输出单元(3)，其中，动力输出单元(3)能够通过接合机构(4)与主齿轮箱(2)接合及分离，该接合机构(4)至少具有使主齿轮箱(2)和动力输出单元(3)接合的第一位置以及使动力输出单元(3)与主齿轮箱(2)分离的第二位置，其中，动力输出单元(3)设有至少一个润滑剂入口(5)。该变速器(1)的特征在于，所述接合机构(4)包括阀构件(6)，从而，当所述接合机构(4)位于其第二位置时，阀构件(6)阻塞所述润滑剂入口(5)，由此防止润滑剂经由润滑剂入口(5)流入动力输出单元(3)，因此，当所述接合机构(4)位于其第一位置时，润滑剂入口(5)打开，且润滑剂能经由润滑剂入口(5)流入动力输出单元(3)。
摘要（英）：

Transmission (1) comprising a main gearbox (2) and a power take off unit (3), wherein the power take off unit (3) can be engaged with, respectively disengaged from, the main gearbox (2) through an engagement mechanism (4) having at least a first position engaging the main gearbox (2) and the power take off unit (3) and a second position disengaging the power take off unit (3) from the main gearbox (2), wherein the power take off unit (3) is provided with at least one lubricant inlet (5). The transmission (1) is characterised in, that said engagement mechanism (4) comprises a valve member (6), whereby when said engagement mechanism (4) is positioned in its second position, the valve member (6) is blocking said lubricant inlet (5), and thereby preventing lubricant to flow through the lubricant inlet (5) into the power take off unit (3), whereby when said engagement mechanism (4) is positioned in its first position, the lubricant inlet (5) is open and lubricant can flow through the lubricant inlet (5) into the power take off unit (3).
