现有的前桥分离器，通过电机机械地使连接套左右移动，使前桥半轴和机械轮连接和断开来实现两轮驱动和四轮驱动的切换。但在很多情况下，前桥半轴的花键与机械轮的花键没有对齐，这使得机械轮的花键会挡住连接套，连接套无法向右移动，从而不能实现前桥半轴和机械轮的连接。而驾驶员在驾驶过程中由于无法得知具体情况，会反复的按动前桥分离器的开关，从而使前桥分离器内部的电机一直动作，会出现电机烧蚀或前桥分离器损坏的问题。
本申请的目的在于提供一种前桥分离器结构，旨在解决前桥半轴的花键与机械轮的花键未对齐，机械轮的花键会挡住连接套，连接套无法向右移动，从而不能实现前桥半轴和机械轮的连接，反复的按动前桥分离器的开关，前桥分离器内部的电机一直动作，造成电机烧蚀或前桥分离器损坏的问题。

优选上述的第二花键410和调节轴的尺寸，能够适配车辆标准零件的尺寸，确保配合精度，便于拆装。
本申请提供的前桥分离器结构，具体工作过程为：
驱动件驱动移动件400向机械轮300一侧移动，移动件400带动连接套520同时套设在前桥半轴200和机械轮300上，连接套520内壁周向的内花键521分别与前桥半轴200和机械轮300上的花键相互配合，此时前桥半轴200和机械轮300借助连接套520连接，整车呈四轮驱动状态。
驱动件驱动移动件400向前桥半轴200一侧移动，移动件400带动连接套520单独套设在前桥半轴200上，使前桥半轴200与机械轮300分离，连接套520内壁周向的内花键521与前桥半轴200上的花键相互配合，此时前桥半轴200不再与机械轮300连接，整车呈两轮驱动状态。
由两轮驱动状态向四轮驱动状态转换过程中，驱动件驱动移动件400向机械轮300一侧移动，如果前桥半轴200的花键与机械轮300的花键没有对齐，连接套520遇阻力后返回原位置，此时调节件600下端的第一齿轮610与连接套520一侧的第二齿轮522啮合，移动件400通过第一花键620和第二花键410的配合，带动调节件600转动，进而带动调节件600下端的第一齿轮610转动，借助相互啮合的第一齿轮610和第二齿轮522，使连接套520也进行相应的小幅度转动，连接套520通过内花键521带动前桥半轴200转动，这样就会使前桥半轴200的花键与机械轮300的花键对齐，从而使下一次连接套520向机械轮300移动时，连接套520能够顺利地套设在机械轮300上，实现前桥半轴200和机械轮300的连接，以达到两轮驱动向四轮驱动切换的目的。
本申请还提供了一种汽车，使用了上述的前桥分离器结构。
本申请提供的汽车，与现有技术相比，由于使用了该前桥分离器结构，因此具备和前桥分离器结构相同的有益效果。能够避免前桥半轴200的花键与机械轮300的花键未对齐时，反复的按动前桥分离器的开关，而出现电机烧蚀或前桥分离器损坏的问题。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
