WHEEL UNIT AND STEERING UNIT FOR CONVEYING DEVICES ON WHEELS SUCH AS BEDS, STRETCHERS OR TROLLEYS

摘要

Described is a steering unit (1) for conveying devices on wheels such as beds, stretchers or trolleys comprising a wheel unit (2) and a motor unit (3). The wheel unit (2) comprises a base structure (4) and a wheel (9) mounted on a supporting element (10) in such a way as to rotate about a relative axis of rotation (11). The supporting element (10) is mounted on the base structure (12) in such a way as to rotate about an orientation axis (12). Transmission means comprise at least an inlet unit and an outlet shaft (16). The inlet unit (15) comprises engagement means designed to reversibly engage the inlet unit on a transmission unit (27) of the motor unit (3). The outlet shaft (16) is integral with the supporting element (10) and defines the orientation axis (12). The transmission means are configured for transforming an inlet motion of the inlet unit (15) into an outlet rotation of the outlet shaft (16) about the orientation axis (12). A motor (26) provided with the transmission unit (27) comprises complementary engagement means designed to operate in conjunction with the engagement means of the inlet unit for reversibly engaging the inlet unit on the transmission unit.
