Directly-driven drive axle with reduction stage for electric vehicles, has revolution rate reducing gear stage with sun wheel that engages fixed position intermediate wheels that drive rotary mounted differential housing

摘要

The axle has an electric motor on the driven motor shaft and a driven shaft for a wheel connected to the motor shaft via a revolution rate reducing gear stage followed by a differential gear mechanism. The revolution rate reducing gear stage has a sun wheel (16) that engages several fixed position intermediate wheels (19) that drive a rotary mounted differential housing (30) whose rotation is converted into a rotary drive for the driven shafts (14,15).
