The invention discloses a four-gear automatic speed change axle for an electric automobile. The four-gear automatic speed change axle comprises a driving motor, a speed changer and a differential mechanism. The transmission is composed of an input shaft, a second shaft, a gear shifting shaft, a main shaft, an intermediate shaft, five sets of meshing gear pairs and two sets of gear shifting executing mechanisms. The gear shifting executing mechanism is composed of two combining teeth and a combining sleeve. The driving motor transmits power to the transmission, multi-stage speed reduction of the transmission is achieved through mutual combined action of the gear shifting executing mechanism, the power is input to the speed reducer, the speed reducer further reduces speed and increases torque, and the output power is shunted from the differential mechanism. The speed reducer has the advantages of wide speed ratio range, economy, high reliability, compact structure and space saving.

    本发明公开了一种电动汽车用四挡自动变速桥,包括驱动电机、变速器、差速器。变速器由输入轴、二轴、换挡轴、主轴、中间轴、五套啮合齿轮副和两套换挡执行机构组成。换挡执行机构由两个结合齿和一个结合套组成。驱动电机将动力传递给变速器,经换挡执行机构的相互组合动作,实现变速器的多级减速并输入动力给减速器,减速器进一步减速增扭从差速器分流输出动力。具有速比范围宽,兼顾经济型和高可靠性,结构紧凑节省空间的优点。
