Description

一种电动汽车用水冷驱动电机
[技术领域]
本实用新型涉及电机冷却领域，具体地说是一种电动汽车用水冷驱动电机。
[背景技术]
目前，很多电动汽车的驱动电机都为水冷电机，采用一个单独的电机对水泵进行驱动来使冷却水循环。这样的结构占用空间比较大，而且成本高，还增加了车重。
[发明内容]
本实用新型的目的是合针对上述不足，设计一种节约空间、减少车重的驱动电机。
为了实现上述目的，本实用新型设计一种电动汽车用水冷驱动电机，包括电机壳体、定子、转子总成、轴承、水泵壳体和水泵叶轮，其特征在于所述电机壳体(1)两端连接端盖(4)，电机壳体内壁连接环形定子(2)，所述电机壳体(1)内部设有转子总成(3)，转子总成(3)一端连接水泵叶轮(7)，水泵叶轮(7)外罩有水泵壳体(8)，转子总成(3)与端盖(4)之间设有轴承(5)，水泵腔体(9)与端盖(4)之间设有水封。
所述水泵壳体(8)中间开有通孔连接进水管，所述水泵壳体侧面开有通孔连接出水管。
所述水泵腔体(9)内设有冷却水。
本实用新型与现有技术相比，其优点在于：水泵与电机结构一体化，减少了水泵的单独动力源、高压转低压的DC/DC和相应的线束等元器件，结构简单，可靠性高，对电动汽车的材料成本也有降低。
[附图说明]
图1为本实用新型的结构图；
参见图1，1为电机壳体，2为定子，3为转子总成，4为端盖，5为轴承，6为水封，7为水泵叶轮，8为水泵壳体，9为水泵腔体。
[具体实施方式]
以下结合附图，对本实用新型做进一步说明。
如图1所示，本实用新型包括电机壳体、定子、转子总成、轴承、水泵壳体和水泵叶轮；电机壳体(1)两端连接端盖(4)，电机壳体内壁连接环形定子(2)，电机壳体(1)内部设有转子总成(3)，转子总成(3)一端连接水泵叶轮(7)，水泵叶轮(7)外罩有水泵壳体(8)，转子总成(3)与端盖(4)之间设有轴承(5)，水泵腔体(9)与端盖(4)之间设有水封。
水泵壳体(8)中间开有通孔连接进水管，所述水泵壳体侧面开有通孔连接出水管。
水泵腔体(9)内设有冷却水。
水泵与电机结构一体化，水泵叶轮(8)安装在电机转子总成(3)上，在电机运转时，电机转子带动水泵叶轮(8)运转，使水泵腔体(9)内的冷却水进行循环。水泵运转的动力源为驱动电机，只要车辆行驶水泵就同步运转，在车辆不行驶的时候驱动电机也不工作，此时水泵不运转。
