System for electric motorisation of a wheel

摘要

The system has a driving unit i.e. ring gear (6), integrated to a wheel (2) carried by a MacPherson strut (3). A clutch device (7) connects an output shaft (8) of a motor block (4) to the driving unit. The motor block having an electric motor (11) e.g. brushless synchronous electric motor, is carried by a non-suspended portion (3a) of the MacPherson strut. The motor block has a reduction device (12) rigidly connected to the electric motor. 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.
