ABSTRACT:
The apparatus is used for driving a mechanically-driven device in an electrical vehicle having at least one electrical traction motor. The apparatus comprises an auxiliary electrical motor mechanically connected to the device. The device is driven by the auxiliary motor when enabling conditions are not met, such as when the traction motor has a rotation speed which is slower than a pre-set rotation speed. When the proper conditions are met, the mechanical connection between the auxiliary motor and the traction motor is engaged and the auxiliary motor is electrically disconnected to save energy. The mechanical connection is disengaged when the proper conditions are no longer met. The apparatus is particularly suitable for use with a power steering pump.
