The invention relates to a hydraulic assembly (1) of an electrically operable axle drive train (2) having at least one electric motor (3) and having a control unit (50), comprising a first hydraulic pump (4) for conveying a first hydraulic fluid (5) from a hydraulic reservoir (6) into a first hydraulic path (7), the switching valve (9) has a first hydraulic connection point (8), which is coupled to a first hydraulic connection point (8) of the first switching valve (9), and wherein the switching valve (9) has a second hydraulic connection point (10), which is coupled to a second hydraulic path (11), which connects the second hydraulic connection point (10) to a first cooling fluid connection point (12) of the electric machine (3), and the electric machine (3) comprises a second cooling fluid connection point (13), which connects the second hydraulic connection point (10) to the first cooling fluid connection point (12) of the electric machine (3). The first switching valve (9) has a second cooling fluid connection point (14) which is connected to a third hydraulic path (14) which is coupled to a third connection point (15) of the first switching valve (9), and wherein the first switching valve (9) has a fourth hydraulic connection point (16) which is coupled to a fourth hydraulic path (17) which leads to the hydraulic reservoir (6).

    本发明涉及一种具有至少一个电机(3)并具有控制单元(50)的可电动操作的车轴传动系(2)的液压组件(1),该液压组件包括第一液压泵(4),第一液压泵用于将第一液压流体(5)从液压贮存器(6)传送到第一液压路径(7)中,该第一液压路径联接至第一切换阀(9)的第一液压连接点(8),其中,切换阀(9)具有第二液压连接点(10),该第二液压连接点联接至第二液压路径(11),第二液压路径将第二液压连接点(10)连接至电机(3)的第一冷却流体连接点(12),并且电机(3)包括第二冷却流体连接点(13),该第二冷却流体连接点连接至第三液压路径(14),该第三液压路径联接至第一切换阀(9)的第三连接点(15),并且其中,第一切换阀(9)具有第四液压连接点(16),第四液压连接点联接至第四液压路径(17),第四液压路径通向液压贮存器(6)。
