    • The invention relates to a fluid pump (10), in particular a liquid pump for a cooling and/or heating circuit of a motor vehicle, having a pump housing (12,14,16,18) and having a rotationally fixed shaft (36), which is arranged in the pump housing (12,14,16,18), for an inner rotor (28) which has an impeller wheel (35). According to the invention, it is proposed that the shaft (28) is mounted at one side and, at its end (42) remote from the bearing point (38), supports a bearing cap (44) which engages at least partially around the shaft (28). The invention also relates to a method for producing a fluid pump (10) of said type, in which method the shaft (36) is fixed with its first end in a housing, in particular in a plastic housing, of the pump, the inner rotor (28) of the pump is pushed onto the shaft (36) and is secured axially by means of a bearing cap (44) which is placed onto the shaft (36) and is supported by the shaft.
    • 本发明涉及一种流体泵(10),特别是液体泵用于机动车辆的冷却和/或加热回路中,具有泵壳体(12,14,16,18)和一个在泵壳体(12,14,16,18)布置, -rotatable轴(36),用于叶轮(35),其具有内转子(28)。 根据本发明,提出的是,轴(28)被安装在一侧,在支承点的你的(38)相对的端部(42)具有轴(28)至少部分地包围所述轴承盖(44)。 本发明还涉及一种方法,用于在泵的一个塑料外壳,所述泵,所述内转子(28)的制造这样的流体泵(10),其中,所述轴(36)被固定在外壳的第一端部,特别是 轴(36)被推动,一个在所述轴(36)装上和由轴轴承盖(44)中进行轴向固定。
