ABSTRACT:
A tandem windshield wiper system including a first windshield wiper assembly having a first lever arm that is adapted to operatively move in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly having a second lever arm is spaced apart from the first windshield wiper assembly and is rotatable about a second wiper longitudinal axis and adapted to operative move in a repeated wiping motion across the surface of the windshield. A brushless DC motor that includes a planetary gear set having an output shaft is disposed between the first and the second wiper assemblies. The gear set is operable to reduce the speed of the rotational output of the motor through the output shaft of said gear set. A bellcrank having a central attachment point and a first and a second end is also included. The central attachment point is fixedly mounted to the output shaft of the motor. A first connecting arm is operatively disposed between the first lever arm and the first end of the bellcrank and is adapted to translate the drive torque from the motor to the first windshield wiper assembly. A second connecting arm is operatively disposed between the second lever arm and the second end of the bellcrank and is adapted to translate the drive torque from the motor to the second windshield wiper assembly.
