Abstract: A manual power pack assembly for an electric power steering (EPS) system includes a motor housing at least partially enclosing a motor and having an outer diameter. The manual power pack assembly also includes a connector plate formed of a material comprising plastic, the connector plate having a first side, a second side, and a cylinder extending from the first side. The manual power pack further includes a metal ring disposed on an inner diameter of the cylinder and in contact with the outer diameter of the motor housing.

Abstract: An electric power steering system includes a mechanical linkage, first and second wheels, an electric motor, first and second speed sensors, and an electronic control unit. The linkage includes a steering column and a rack operatively engaged to the steering column. The first and second wheels are rotationally engaged to opposite ends of the rack. The motor is operatively attached to the linkage for providing steering assistance. The first and second speed sensors are configured to detect rotation speed of the respective first and second wheels. The unit is configured to receive first and second rotational speed signals from the respective first and second speed sensors, and calculate a first rotational speed differential between the first and second wheels to facilitate an estimation of a steering column angular position for controlling the electric motor.

Abstract: An electric power steering system includes an electric motor including a motor output shaft. The system also includes a worm operatively coupled to the motor output shaft. The system further includes a worm gear in contact with the worm and operatively coupled to an auxiliary shaft. The system yet further includes a drive gear operatively coupled to the auxiliary shaft. The system also includes a driven gear in contact with the drive gear and operatively coupled to an input shaft to drive a manual recirculating ball steering gear.

Abstract: A motor vehicle electric motor assembly includes a motor housing having an annular wall extending from a housing first end to an opposite housing second end about a central axis to bound a cavity. The housing first end has a base configured to support a bearing housing. A motor shaft extends along the central axis between a shaft first end and a shaft second end. A rotor is fixed to the shaft for rotation about the central axis. A stator is supported by the annular wall in radially spaced relation from the rotor. A bearing is fixed in the bearing housing to support the shaft first end for rotation about the central axis. An end cover assembly is fixed to the housing second end. The end cover assembly has a motor shaft opening with a periphery of the motor shaft opening supporting the shaft second end for rotation about the central axis.
