The embodiment of the invention provides an axle gear box, a bogie and an engineering vehicle, and relates to large road maintenance mechanical equipment. The axle gear box aims at solving the problems that a sliding type gear shifting gear box in the related technology is large in gear meshing backlash, high in vibration, not suitable for high-precision working conditions and high in damage to working devices. The axle gear box comprises a large box body; a small box body arranged in the large box body; an axle gear arranged in the large box body; and a gear shifting mechanism provided with a driving part, a bracket and a connecting plate. The driving part is installed in the large box body, the bracket is installed in the large box body, one end of the bracket is hinged to the driving part, and the other end of the bracket is hinged to the small box body through the connecting plate. When the driving part drives the small box body to rotate to a first position relative to the large box body through the bracket and the connecting plate, a first gear of a driven gear shaft is separated from the axle gear of an axle; and when the driving part drives the small box body to rotate to a second position relative to the large box body through the bracket and the connecting plate, the first gear of the driven gear shaft is meshed with the axle gear of the axle.

    本申请实施例提供一种车轴齿轮箱、转向架及工程车辆,涉及大型养路机械设备,用于克服相关技术中滑移式换挡齿轮箱,齿轮啮合侧隙大振动大,不适用于高精度作业工况、对工作装置损伤大的问题。车轴齿轮箱包括:大箱体;小箱体,设于大箱体中;车轴齿轮,设于大箱体中;换挡机构,具有驱动件、托架、连接板;驱动件安装于大箱体,托架安装于大箱体内,托架的一端与驱动件铰接,托架的另一端通过连接板与小箱体铰接;其中,驱动件通过托架及连接板驱动小箱体相对于大箱体转动至第一位置时,从动齿轮轴的第一齿轮与车轴的车轴齿轮分离;驱动件通过托架及连接板驱动小箱体相对于大箱体转动至第二位置时,从动齿轮轴的第一齿轮与车轴的车轴齿轮啮合。
