Wheel motorising system for a wheel suspension

摘要

The system has a driving unit i.e. ring gear (4), integrated to a wheel that is carried by a MacPherson strut (2). A motor block (3) is integrated to a suspended portion of the MacPherson strut. A clutch device (6) connects an output shaft of the motor block to the driving unit. The motor block has a reduction device rigidly connected to an electric motor (10) e.g. brushless synchronous electric motor, of the motor block. The clutch device moves the motor block between an engaged position and a disengaged position in which the motor block is separated from the driving unit.
