图1是安置ABS信号结构的车桥；
图2是图1中区域A的放大图。
附图标记：

外壳2；半轴连接头3；ABS信号齿轮4；ABS传感器5；容置槽6；紧固件7；台阶部8；轴承9；油封10；密封圈11；主体12；安装板13。
具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。
下面参考图1-图2描述根据本公开实施例的车辆的车桥1。
如图1所示，根据本公开的车辆的车桥1包括：外壳2、半轴连接头3、ABS信号齿轮4和ABS传感器5。
外壳2设置有安装孔，半轴连接头3设置于外壳2内，半轴连接头3用于连接等速半轴，等速半轴连接车轮。ABS信号齿轮4固定于半轴连接头3上且与半轴连接头3同步转动，即ABS信号齿轮4也位于外壳2内，ABS信号齿轮4的固定方式可以为花键配合，也可以为紧固件固定的方式。
ABS传感器5设置于外壳2内，具体地，其可以设置于外壳2的安装孔处，也就是 说，ABS传感器5安装在安装孔处。ABS传感器5用于检测ABS信号齿轮4的转速。基于此，在车辆行驶过程中，通过ABS传感器5可以检测ABS信号齿轮4的转速，从而可以通过计算获知车辆传递到半轴和车轮处的转速，ABS传感器5可以将转速信息转化成电子信号传递给对应的控制器。通过将ABS传感器5安装在安装孔处，可以减少ABS传感器5的暴露部分，而且通过将ABS信号齿轮4内置在外壳2内部，至少一定程度上能够避免外部环境对两者的干扰，例如可以避免灰尘、泥土和水的干扰。
进一步地，如图2所示，ABS传感器5套设有密封圈11。密封圈11可以密封在ABS传感器5和安装孔之间的缝隙处，可以更好地避免外部环境中的异物进入到外壳2内部空间，从而可以更好地保护ABS传感器5和ABS信号齿轮4，可以使得ABS传感器5和ABS信号齿轮4正常工作。
如图2所示，ABS传感器5的周向设置有容置槽6，密封圈11的一部分容置于容置槽6内。容置槽6可以与密封圈11配合，使密封圈11起到阻止灰尘、泥土和水进入ABS传感器5，从而保证ABS传感器5可以正常工作。容置槽6的设置可以方便密封圈11设置在ABS传感器5上，而且密封圈11可以先设置在ABS传感器5上，然后再整体装配到安装孔内，如此设置的密封圈11和ABS传感器5可以降低装配难度，而且可以避免密封圈11在装配过程中受到损坏，从而可以更好地保证外壳2内部的密封效果。
具体地，如图1所示，ABS传感器5包括：相连接的主体12和安装板13，主体12配合于安装孔内，容置槽6形成于主体12上，安装板13通过紧固件7安装于外壳2。通过安装板13以及紧固件7的固定，主体12能够被稳定地安装于车桥1上。而且安装板13可以通过紧固件7安装在外壳2的外侧，从而可以降低ABS传感器5的安装难度。
另外，半轴连接头3的外周设置有第一限位部，ABS信号齿轮4的内周设置有第二限位部，第一限位部和第二限位部限位配合。通过周向设置第一限位部和第二限位部，ABS信号齿轮4在半轴连接头3转动时，会依靠第二限位部与第一限位部配合进行同步的转动。第二限位部与第一限位部转速一致，ABS传感器5通过采集ABS信号齿轮4的转速信号，可以准确地测量出半轴连接头3的转速，即车轮的转速，进而可以通过控制器调整车轮的转速，发挥ABS的作用。
具体地，第一限位部包括至少两个在半轴连接头3周向间隔的限位块，第二限位部包括至少两个在ABS信号齿轮4周向间隔的限位槽，限位块与限位槽限位配合。设置如此数量的限位块与限位槽，能够保证限位块和限位槽限位配合的可靠性，可以进 一步地保证半轴连接头3和ABS信号齿轮4的配合可靠性。
或者，第一限位部为第一花键，第二限位部为第二花键，第一花键和第二花键相互配合，通过花键配合的方式，可以保证半轴连接头3和ABS信号齿轮4的配合可靠性，而且易于装配。其中，第一花键和第二花键中的一个为内花键，而且第一花键和第二花键中的另一个为外花键。
另外，半轴连接头3与ABS信号齿轮4间隙配合，通过间隙配合方式，ABS信号齿轮4能够被方便地安装到半轴连接头3上，从而可以降低ABS信号齿轮和半轴连接头3之间的装配难度。
如图1所示，半轴连接头3外周通过两段半径差形成有台阶部8，具体地，半轴连接头3的外周可以在轴向上形成有大径段和小径段，大径段位于小径段的轴向内侧，大径段和小径段之间的连接处形成上述的台阶部8。ABS信号齿轮4的轴向内侧表面贴设于台阶部8。通过设置台阶部8，ABS信号齿轮4的轴向内侧被限定在半轴连接头3台阶部8。
进一步地，如图1所示，轴承9套设于半轴连接头3上，轴承9位于ABS信号齿轮4的轴向外侧。轴承9可以起到支承半轴连接头3的作用，而且由于轴承9设置于ABS信号齿轮4的轴向外侧，其一定程度上还能够起到轴向限制ABS信号齿轮4的作用，即其可以起到防止ABS信号齿轮4轴向向外窜动的作用，从而可以保证ABS信号齿轮4在半轴连接头3上的轴向稳定性。
另外，如图1所示，油封10位于ABS信号齿轮4的外侧，油封10设置于外壳2和半轴连接头3之间。通过设置油封10，外壳2内部的润滑油无法通过外壳2和半轴连接头3之间的缝隙向外泄漏侧，从而可以提高外壳2的密封性，以及可以保证外壳2的内部运动部件的工作稳定性。
根据本公开的的车辆，包括上述实施例的车桥1。该车辆可以是指陆地上用轮子转动的交通工具。
