下面参考附图描述根据本公开实施例的车轮2.
如图5和图6所示，根据本公开实施例的车轮2包括轮毂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轮毂1。
如图1-图4所示，根据本公开实施例的轮毂1包括第一子轮毂10和第二子轮毂20。
第一子轮毂10和第二子轮毂20沿轮毂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在轮毂1的外周面共同限定出轮胎安装槽40。具体而言，第一子轮毂10和第二子轮毂20为轮毂1的组成部分，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，构成轮毂1的中心轴线，第一子轮毂10和第二子轮毂20可沿轮毂1的轴向分体设置。轮胎安装槽40沿轮毂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构成的封闭面。
在根据本公开实施例的车轮2中，轮胎3安装在轮胎安装槽40内。
在本公开的一些示例中，如图1和图2所示，轮胎安装槽40的两侧壁可以设有筋条41，筋条41可以为L形，筋条41从轮胎安装槽40的侧壁延伸至轮胎安装槽40的底壁，且筋条41垂直于轮胎安装槽40的周向设置，筋条41沿轮胎安装槽40的周向间隔排列成两圈，即每圈筋条41沿轮胎安装槽40的周向间隔设置且两圈筋条41沿轮毂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轮毂1及车轮2，通过将轮毂1沿其轴向设置为第一子轮毂10和第二子轮毂20，由此构成分体结构，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和第二子轮毂20呈分开状态，先将轮胎3套装于第一子轮毂10上，然后再将第二子轮毂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40，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。
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轮毂1和车轮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可拆卸地安装于轮盘110，第一轮圈120的一侧周沿与轮盘110的外周沿相连，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构成轮胎安装槽40的一侧壁。
具体而言，轮盘110为盘形，轮盘110可嵌入第二子轮毂20中。第一轮胎限位圈130位于第一轮圈120的远离第二子轮毂20的一侧，且第一轮胎限位圈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构成轮胎安装槽40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。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装配方便。
进一步的，第二子轮毂20包括第二轮圈210和第二轮胎限位圈220。
其中，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 构成所胎安装槽40的另一侧壁。
换言之，第二轮胎限位圈220与第二轮圈210的中心轴线彼此重合，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40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40的两侧壁。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40。
可选地，如图5所示，第一轮圈120与第二轮圈210可以对接，即第一轮圈120与第二轮圈210的直径相同，轴心线重合，且第二轮圈210与第一轮圈120轴向相对的一面贴合。如此，可以保证轮毂1安装轮胎受力均匀合理，使用寿命长。
进一步的，第一轮圈120的朝向第二轮圈210的一侧周沿和第二轮圈210的朝向第一轮圈120的一侧周沿中的一个上设有定位凸起140起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，定位凸起140设于第一轮圈120上，而定位凹槽230设于第二轮圈210上。如此，保证了第一子轮毂10与第二子轮毂20在轮毂1的周向上的相对位置固定，且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。
在本公开的一些具体实施例中，如图4所示，轮盘110设有沿其周向间隔设置的多个安装结构150，第二轮圈210的内周侧构造有安装环部240，即安装环部240从第二轮圈210沿第二轮圈210的径向向内延伸，且安装环部240围绕在第二轮圈210的整个周向上，安装环部240止抵于轮盘110且安装于多个安装结构150。
具体地，安装结构150设有安装孔160，安装环部240设有装配孔250，安装环部240通过穿过装配孔250且配合在安装孔160内的紧固件30安装于安装结构150。
例如，多个安装结构150沿轮盘110的周向等间距设置，且在轮盘110上朝向第二子轮毂20凸起。安装环部240在第二轮圈210的内周侧构造，且朝向轮盘110的一面有多个凹陷结构，安装结构150与所述凹陷结构相对应。安装环部240配合于轮盘110。如此，轮毂1的结构合理，第一子轮毂10与第二子轮毂20配合紧密。
其中，装配孔250设于所述凹陷结构中，安装孔160位于安装结构150径向向外的部分，紧固件30可为螺纹紧固件，例如螺栓，安装孔160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2、图4、图6所示，安装结构150具有定位爪170，多个安装结构150的定位爪170止抵在安装环部240的内周沿。
具体而言，定位爪170与安装孔160数量相对应，且定位爪170在轮盘110的径向上位于安装孔160的内侧。定位爪170可以呈U型结构，其U型开口沿径向朝外。第一子轮毂10与第二子轮毂20安装后，定位爪170的U型开口抵安装环部240的内周沿上。如此，在轮毂1的径向上，使第一子轮毂10与第二子轮毂20的相对位置固定，保证轮毂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4所示，第一子轮毂10和第二子轮毂20中的一个上构造有轴承安装结构180，轴承安装结构180用于安装轴承，如此，可以将轴承均安装在第一子轮毂10 或第二子轮毂20上，即安装在同一个子轮毂上，进而保证了同心度和圆跳度。
例如，轴承安装结构180形成于第一子轮毂10，具体地，轴承安装结构180可以形成于轮盘110，第二子轮毂20通过安装环部240安装于第一子轮毂10，轴承安装结构180被安装环部240围绕。
