本实用新型的有益效果：
1、轮边减速器设置在车轮的轮毂内，使得整个驱动桥结构更加紧凑，同时降低一级主减速器、半轴、和差速器的负荷，减少传动部件的结构尺寸，保证后桥有足够的离地间隙，提高了抓草机的通过性能，半轴轴头较粗，不容易断半轴，并降低了抓草机整机装备质量。
2、采用碟刹，制动效果好。

具体实施方式
下面结合附图对本实用新型作进一步的说明。
轮边减速器四驱抓草机，包括变速箱1，所述变速箱1通过前万向传动轴3驱动前驱动桥4，前驱动桥4驱动前轮6；所述变速箱1通过后万向传动轴7驱动后驱动桥11，后驱动桥11驱动后轮8，所述前驱动桥4与前轮6之间设置有前轮边减速器5，所述后驱动桥11与后轮8之间设置有后轮边减速器10，所述前轮边减速器5和后轮边减速器11包括轮毂12、行星齿轮架13、轮边支撑轴21、内齿圈19和太阳轮17，所述轮边支撑轴21套装在半轴22上，其一端与半轴壳23固定连接，另一端与内齿圈19花键联接并通过轮边支撑轴螺母18将内齿圈19与轮边支撑轴21紧固；所述内齿圈19的外圆与轮边支撑轴21的外圆通过轴承支撑轮毂12，所述轮毂12的一端与行星齿轮架13固定连接，所述行星齿轮架13上设置有行星齿轮轴14，所述行星齿轮轴14上转动连接有行星齿轮15，所述行星齿轮15分别与内齿圈19的内齿和太阳轮17的外齿相啮合，所述太阳轮17与半轴22花键联接并通过半轴螺母16将太阳轮17与半轴22紧固。轮边减速器设置在车轮的轮毂内，使得整个驱动桥结构更加紧凑，同时降低一级主减速器、半轴、和差速器的负荷，减少传动部件的结构尺寸，保证后桥有足够的离地间隙，提高了抓草机的通过性能，半轴轴头较粗，不容易断半轴，并降低了抓草机整机装备质量。
所述轮毂12的周边设计有安装车轮的凸缘，凸缘上钻孔通过轮辋螺栓安装车轮。
所述轮毂12的另一端固定连接有制动盘20，所述半轴壳23上设置有行车制动器9并作用于制动盘20。采用碟刹，制动效果好。
本实用新型工作原理：
发动机的动力经变速箱后通过前、后万向传动轴把动力传递到前、后驱动桥，再从前、后驱动桥的输出端传递到前、后轮边减速器及前、后车轮，以驱动抓草机前进或后退。在这一过程中，轮边减速器的工作原理是：半轴22带动太阳轮17转动，太阳轮17驱动星齿轮15转动，行星齿轮15与内齿圈19的内齿啮合带动行星齿轮架13转动，从而带动轮毂12转动。其作用就是把前、后驱动桥传递的转速和扭矩经过降速增矩后，再传递给车轮，提高传动效率，以便使车轮在地面附着力的反作用下，产生较大驱动力。从而减少了轮边减速器前面各零件的受力。
以上通过实施例形式的具体实施方式，对本实用新型作了详细的说明，但不应将此理解为本实用新型上述主题范围仅限于以上的具体实施方式，凡基于本实用新型上述内容所以实现的技术均属于本实用新型的范围。
