Abstract
A bearing axle with straight shell and hollow cross section, is characterized in that the horizontal cross section of the axle housing is hollow, space of which is laid out an electric motor, a gearshift, a final drive and a differential. The advantages of the invention are as follows: the electric motor, final drive and differential integrated on the electric drive axle are fixed on the chassis to reduce the unsprung mass. The height of the motor is increased to change its adverse operation circumstances and the electric motor is not easy to be demagnetized. If the transmission is used, the gearshift on the spring is smoother than the gearshift under the spring.

A bearing axle with straight shell and hollow cross section consists of an axle housing, arc-shaped steel plates, half shaft tubes, and so on. Horizontal cross section of the axle housing is hollow, space of which is laid out an electric powertrain fixed on chassis. The electric powertrain is made up of an electric motor, a final drive, and a differential etc. The differential transmits power of electric motor to driving shafts. The driving shafts transmit the power to wheels, and then, vehicle is driven forward by wheels.
