Introduction of transmission shaft category

A drive shaft (b, c) which is located between the left and right drive wheels (2, 4) of the motor vehicle (a) and provides power for the left and right drive wheels, and the electric drive shaft includes motors (22, 84) and left and right torque couplings (24, 26). The torque generated by the motor is transmitted to the driving shaft connected with the driving wheel through the torque coupling (10, 12). Each torque coupling includes a magnetic powder clutch (42) and a planetary gear set (44), which are configured such that the current flowing through the electromagnet of the clutch controls the torque transmitted through the coupling. The magnetic powder clutch can also slip, making the driving wheel rotate at different angular velocities.
