The present document relates to an electric drive axle comprising an electric motor, a first planetary gear set, a second planetary gear set, and a differential assembly. The electric motor is drivingly connected or drivingly connectable to the differential assembly via the first planetary gear set and via the second planetary gear set.

The present embodiments may provide a steer-by-wire steering apparatus which enables a driver to use a function for controlling an automobile, such as automatic parking, lane keeping, driving assistance according to a road surface condition, steering-vibration damping, or autonomous driving control, to improve the driver's convenience, and allows removal of hydraulic pressure-related components to prevent consumption of engine power by the components and thus can satisfy the high power and rigidity required for a steering device of a commercial vehicle.

The present disclosure relates to a cycloidal reducer. The cycloidal reducer according to the present disclosure includes a reduction unit configured to reduce a torque input and an output unit configured to transfer the reduced output to the outside. A cycloidal rotor that is one constituent element of the reduction unit has a tooth-type protrusion formed in the shape of a circular arc. Thus, the level of difficulty of process is decreased more than when the tooth-type protrusion in the related art is formed in the shape of a broken line. Accordingly, the advantage of increasing the productivity is provided. In addition, rotor pins are accommodated in through-holes, respectively, that are equally spaced in the cycloidal rotor. A busing is formed that fills a gap between the through-hole and the rotor pin is formed in order for the rotor pin to stably transfer rotational power. Accordingly, the advantage of effectively distributing a load and stably transferring a reduction torque to the outside is provided.
