Claims17
A driving module comprising:
- a drive unit comprising a wheel and a drive motor configured to operate the wheel;
- a suspension unit having a first side coupled to the drive unit;
- and
- a steering unit configured to steer the wheel and having a side coupled to a second side of the suspension unit,
- wherein the steering unit comprises:
- a steering motor comprising a steering rotary shaft;
- a speed reducer coupled to the steering rotary shaft;
- an inner frame having an internal space formed through the inner frame in an upward/downward direction, the inner frame configured to rotate together with the speed reducer;
- a slip ring disposed in the internal space of the inner frame and having a side coupled to the inner frame;
- a first electric wire connected to the slip ring;
- and
- a second electric wire connected to the slip ring and extending from the slip ring to the suspension unit,
- wherein the suspension unit comprises:
- a connection member fixedly coupled to a lower region of the inner frame;
- a shaft member coupled to a lower region of the connection member and extending in the upward/downward direction;
- a bushing member into which the shaft member is inserted, the bushing member being configured to be movable in the upward/downward direction along the shaft member;
- and
- a knuckle member having a first side coupled to the bushing member and a second side coupled to the drive unit, and
- wherein:
- the second electric wire penetrates an internal space of the shaft member of the suspension unit and an internal space of the knuckle member of the suspension unit to connect to the drive unit, and
- the first electric wire and the second electric wire are connected in series through the slip ring in the steering unit.
