Abstract:

A tandem windshield wiper system that includes at least one brushless DC motor to provide drive torque through an output that is rotatable about the longitudinal axis of the motor. A first windshield wiper assembly having a first lever arm is driven by the motor about the longitudinal axis in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly spaced apart from the first windshield wiper assembly has a second lever arm and is rotatable about a second longitudinal axis to operative move in a repeated wiping motion across the surface of the windshield. A connecting arm is also included that is operatively disposed between the first and the second lever arms that is adapted to translate the drive torque provided to the first windshield wiper assembly to the second windshield wiper assembly. The motor includes a planetary gear set having an output shaft. The gear set being coaxially disposed relative to the rotational output and the longitudinal axis of the motor and operatively interconnecting the drive torque to the first and the second windshield wiper assemblies.
