下面参考附图描述根据本公开实施例的轮毂电机2。
如图5和图6所示，根据本公开实施例的轮毂电机2包括电机轮毂1和轮胎3，轮胎3可以为实心胎或填充胎。
首先参考附图描述根据本公开实施例的电机轮毂1。
如图1-图4所示，根据本公开实施例的电机轮毂1包括第一子轮毂10、第二子轮毂20和端盖30。
第一子轮毂10构造有电机内腔160，第一子轮毂10和第二子轮毂20沿电机轮毂1的轴向分布， 第二子轮毂20可拆卸地安装于第一子轮毂10，第一子轮毂10和第二子轮毂20在电机轮毂1的外周面共同限定出轮胎安装槽60，端盖30安装于第一子轮毂10且封盖电机内腔160。
具体而言，第一子轮毂10、第二子轮毂20和端盖30为电机轮毂1的组成部分。第一子轮毂10构造有电机内腔160，电机内腔160的朝向第二子轮毂20的一面为封闭面，另一面具有开口，其内部为空腔，可容纳电机轮毂1的电机部件，如定子、转子等。其中，第一子轮毂10的中心轴线和第二子轮毂20的中心轴线相互重合，构成电机轮毂1的中心轴线，第一子轮毂10和第二子轮毂20可沿电机轮毂1的轴向分体设置。轮胎安装槽60沿电机轮毂1的径向向外有开口，其余各面为由第一子轮毂10和第二子轮毂20构成封闭面。端盖30安装于第一子轮毂10上，其面积大于电机内腔160的所述开口的面积，且封盖电机内腔160的所述开口一面，端盖30中间设有供转轴穿过的通孔31。
在根据本公开实施例的轮毂电机2中，轮胎3安装在轮胎安装槽60内。
在本公开的一些示例中，如图1和图2所示，轮胎安装槽60的两侧壁可以设有筋条61，筋条61可以为L形，筋条61从轮胎安装槽60的侧壁延伸至轮胎安装槽60的底壁，且筋条61垂直于轮胎安装槽60的周向设置，筋条61沿轮胎安装槽60的周向间隔排列成两圈，即每圈筋条61沿轮胎安装槽60的周向间隔设置且两圈筋条61沿电机轮毂1的轴向间隔设置。一方面能够起到加强结构的作用，另一方面能够与轮胎3形成一定的挤压，通过力的相互作用，防止轮胎3与电机轮毂1滑移，从而提高轮胎3的稳定性。
根据本公开实施例的电机轮毂1及轮毂电机2，通过将电机轮毂1沿其轴向设置为第一子轮毂10、第二子轮毂20和端盖30，由此构成分体结构，因此，可以极大地方便轮胎3的拆装。
具体而言，在安装过程中，第一子轮毂10、第二子轮毂20和端盖30呈分开状态，先将电机轮毂1的电机部件安装于电机内腔160中，再将端盖30安装于第一子轮毂10上，且封盖于电机内腔160；然后将轮胎3套装于第一子轮毂10上，再将第二子轮毂20压合到第一子轮毂10上，使第一子轮毂10和第二子轮毂20共同限定出夹持轮胎3的轮胎安装槽60，从而完成轮胎3的安装。
在拆卸过程中，先将第二子轮毂20从第一子轮毂10上拆卸下来，由于轮胎3不再受到夹持，因此可轻松将轮胎3从第一子轮毂10上拆卸下来，完成轮胎3的拆卸；然后将端盖30从第一子轮毂10上拆卸下来，再将电机内腔160中的电机轮毂1的电机部件拆卸完毕。
由此，轮胎3的拆装十分方便，进而可以大幅提高生产效率，且在装配过程中不易发生损坏，降低了不良率，并且，由于轮胎3的拆装方便，可以便于后续的维护更换。
因此，根据本公开实施例的电机轮毂1及轮毂电机2能够方便轮胎3的拆装，从而提高生产效率、降低不良率、便于维护更换。
在本公开的一些具体实施例中，如图1-图4所示，第一子轮毂10包括轮盘110、第一轮圈120和第一轮胎限位圈130。
其中，第二子轮毂20可拆卸地安装于第一轮圈120，第一轮圈120的一侧周沿与轮盘110的外周沿相连，第一轮圈120和轮盘110共同限定出电机内腔160，第一轮胎限位圈130的内周沿与第 一轮圈120的另一侧周沿相连，第一轮胎限位圈130构成所述轮胎安装槽60的一侧壁。
具体而言，轮盘110为盘型，中间有供转轴穿过的通孔，轮盘110构成电机内腔160的封闭面。第一轮圈120可嵌入第二子轮毂20中。第一轮圈120的朝向第二子轮毂20的一侧周沿与轮盘110的外周沿连接。第一轮胎限位圈130位于第一轮圈120的远离第二子轮毂20的另一侧周沿，且第一轮胎限位圈130的内周沿与第一轮圈120的所述另一侧周沿相连，第一轮胎限位圈130构成轮胎安装槽60的一侧壁。轮盘110、第一轮圈120和第一轮胎限位圈130一体成型且中心轴线彼此重合。第一轮圈120和轮盘110共同限定出电机内腔160，即第一轮圈120的内周面、轮盘110的远离第二子轮毂20的一面和端盖30所限定的空间即为电机内腔160。如此，第一子轮毂10的结构稳定合理、加工方便，且与第二子轮毂20和端盖30装配方便。
进一步的，第二子轮毂20包括第二轮圈210、第二轮胎限位圈220和止挡圈250。
其中，第二子轮毂20安装于第一子轮毂10时，第二子轮毂20的第二轮圈210与第一子轮毂10的第一轮圈120相接。第二轮胎限位圈220的内周沿与第二轮圈210的远离第一子轮毂10的一侧周沿相连，第二轮胎限位圈220构成轮胎安装槽60的另一侧壁，止挡圈250的外周沿与第二轮圈210的远离第一子轮毂10的一侧周沿相连，止挡圈250止挡在第一轮圈120的所述一侧周沿(即第一轮圈120的与轮盘110相连的周沿)。
换言之，第二轮胎限位圈220在第二轮圈210的远离第一子轮毂10的一侧周沿沿第二子轮毂20的径向向外延伸，且封闭环绕于第二轮圈210，第二轮胎限位圈220与第二轮圈210的中心轴线彼此重合。第二子轮毂20安装于第一子轮毂10时，第二轮圈210与第一轮圈120相连，即第一轮圈120的外周面和第二轮圈210的外周面一同构成轮胎安装槽60的底壁，而第一轮胎限位圈130和第二轮胎限位圈220分别构成轮胎安装槽60的两侧壁。止挡圈250在第二轮圈210的所述一侧周沿沿第二子轮毂20的径向向内延伸，且封闭环绕于第二轮圈210。第二轮圈210、第二轮胎限位圈220和止挡圈250一体成型。如此，第二子轮毂20的结构稳定合理、加工方便。并且，第一子轮毂10和第二子轮毂20装配形成能够夹持轮胎3的轮胎安装槽60。
可选的，第二子轮毂20安装于第一子轮毂10时第二轮圈210可以套设在第一轮圈120的外侧。换言之，第一轮圈120的靠近第二轮圈210的一侧周沿可嵌入第二轮圈210。如此，第一子轮毂10与第二子轮毂20拆卸方便，配合紧密，结构稳定。
进一步的，如图3-图4所示，第一轮圈120的外周面设有沿其周向延伸的沉槽170，第二轮圈210装配在沉槽170内，由此可以使第一轮圈120的外周面和第二轮圈210的外周面平齐。
具体的，沉槽170的底壁和第二轮圈210的内周面中的一个上设有定位凸起140且另一个上设有定位凹槽230，定位凸起140配合在定位凹槽230内。例如，第一轮圈120的沉槽170的底壁设有定位凸起140，第二轮圈210的内周面设有定位凹槽230，如此，保证了第一子轮毂10与第二子轮毂20在电机轮毂1的周向上的相对位置固定，在装配过程中可以对第一子轮毂10和第二子轮毂20进行预定位，进一步方便装配。
进一步的，定位凸起140为多个且沿第一轮圈120的周向间隔设置在沉槽170的底壁，定位凹 槽230为多个且沿第二轮圈210的周向间隔设置在第二轮圈210的内周面，多个定位凸起140一一对应地配合在多个定位凹槽230内。
在本公开的一些具体示例中，如图3和图4所示，定位凸起140的朝向止挡圈250的一端构造有安装孔150，止挡圈250设有装配孔240，止挡圈250通过穿过所述装配孔240且配合在安装孔150内的第一紧固件40安装于定位凸起140。
例如，多个定位凸起140沿第一轮圈120的周向等间距间隔设置在沉槽170的底壁，且在在沉槽170的底壁沿第一轮圈120的径向向外凸起。多个安装凹槽230且沿第二轮圈210的周向等间距间隔设置在第二轮圈210的内周面，且在第二轮圈210的内周面沿第二轮圈210的径向向外凹陷。定位凸起140与定位凹槽230一一对应地配合安装。
其中，装配孔240设于止挡圈250上，装配孔240的数量与定位凹槽230的数量相同，且一一对应。装配孔240在第二轮圈210的径向上位于定位凹槽230内侧。定位凸起140的朝向止挡圈250的一端构造有安装孔150。第一紧固件40可为螺纹紧固件，例如螺栓，安装孔150可为配合紧固件30的螺纹孔。如此，可以将第一子轮毂10与第二子轮毂20固定，保证电机轮毂1结构稳定和便于拆卸。
在本公开的一些具体实施例中，如图3-图4所示，第一轮圈120和轮盘110的连接处构造有环槽180，止挡圈250配合在环槽180内。如此，进一步的提高了第一子轮毂10与第二子轮毂20的配合紧密度，使电机轮毂1的结构稳定，且电机轮毂1的外观更加平整。
在本公开的一些具体实施例中，如图2-图4所示，端盖30通过沿其周向分布的多个第二紧固件50安装于第一轮圈120。具体而言，第二紧固件50可为螺纹紧固件，例如螺栓，第一轮圈120朝向端盖30的方向有与第二紧固件50的紧固件配合安装结构，例如螺纹孔。如此可以将第一子轮毂10与端盖30固定，保证电机轮毂1结构稳定和便于拆卸。
