The invention provides a four-gear automatic speed change axle for an electric automobile and a vehicle, the four-gear automatic speed change axle for the electric automobile comprises a driving motor, a speed changer and a speed reducer, the speed changer is composed of an input shaft, a second shaft, a gear shifting shaft, a main shaft, an intermediate shaft, five sets of gear pair mechanisms and two sets of gear shifting executing mechanisms, and the driving motor transmits power to the speed changer; multi-stage speed reduction of the transmission is achieved and power is input to the speed reducer through mutual combined action of the gear shifting executing mechanism, the speed reducer further reduces speed and increases torque, and output power is shunted from the differential mechanism. The high-integration transversely-arranged double-section single-intermediate-shaft multi-gear multi-stage transmission has the advantages of being wide in speed ratio range, economical, high in reliability, compact in structure and capable of saving space.

    本发明提供一种电动汽车用四档自动变速桥及车辆,其中,电动汽车用四档自动变速桥包括驱动电机、变速器、减速器,变速器由输入轴、二轴、换挡轴、主轴、中间轴、5套齿轮副机构、2套换挡执行机构组成,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。本发明通过高集成的横置双段单中间轴多档多级变速器,其具有速比范围宽,兼顾经济型和高可靠性,结构紧凑节省空间的优点。
