The invention relates to a speed reducer, a drive axle and a vehicle, the speed reducer comprises a planetary gear set, the planetary gear set comprises a sun gear, a planetary gear, a planetary carrier and a gear ring, the sun gear is driven by external power to rotate around a first axis, the planetary carrier is fixed on an external structure, and the gear ring rotates around the first axis along with the sun gear through the planetary gear installed on the planetary carrier; the driving bevel gear is mounted on the outer surface of the gear ring so as to revolve around a first axis, the driving bevel gear can also rotate around a second axis relative to the gear ring, and the second axis is perpendicular to the first axis; the driven bevel gear can rotate around the first axis and is meshed with the driving bevel gear. The rotating speed and the torque received by the sun gear are jointly decelerated through the planet gear, the gear ring, the driving bevel gear and the driven bevel gear, and then can be transmitted and output to wheels through the driven bevel gear. Meanwhile, the two driven bevel gears are matched with the driving bevel gear to replace a differential mechanism, the rotating speed difference of wheels on the two sides of the vehicle is automatically adjusted, and normal running of the vehicle is guaranteed.

    本发明涉及一种减速器、驱动桥和车辆,减速器包括:行星轮组,包括太阳轮、行星轮、行星架和齿圈,太阳轮受外部动力驱动绕第一轴线转动,行星架固定在外部结构上,齿圈通过安装在行星架上行星轮随太阳轮绕第一轴线转动;主动锥齿轮,安装于齿圈的外表面上,以绕第一轴线公转,主动锥齿轮还能够相对齿圈绕第二轴线自转,第二轴线和第一轴线垂直;从动锥齿轮,绕第一轴线可转动,并与主动锥齿轮相互啮合。太阳轮接收的转速和扭矩经过行星轮、齿圈、主动锥齿轮和从动锥齿轮共同减速之后,便可以通过从动锥齿轮传递输出给车轮。同时,两个从动锥齿轮配合设置主动锥齿轮便可以替代差速器,来自动调整车辆两侧车轮的转速差异,保证车辆正常行驶。
