Abstract: A steering unit for conveying devices on wheels such as beds, stretchers or trolleys includes a wheel unit and a motor unit. The wheel unit includes a base structure and a wheel mounted on a supporting element to rotate about an axis. The supporting element is mounted on the base structure to rotate about an orientation axis. A transmission includes an inlet unit and outlet shaft. The inlet unit includes an engagement device to reversibly engage the inlet unit on a transmission unit of the motor unit. The outlet shaft is integral with the supporting element and defines the orientation axis. The transmission transforms an inlet motion of the inlet unit into an outlet rotation of the outlet shaft about the orientation axis. A motor includes a complementary engagement device operating with the engagement device for reversibly engaging the inlet unit on the transmission unit.
