A windshield wiper system (WWS) is provided. The WWS includes a brushless direct current (BLDC) motor, a wiper arm and blade, a gearbox/converter operably interposed between the BLDC motor and the wiper arm and blade and a smart motor drive configured to determine a WWS failure condition and to operate the BLDC motor according to the determination.

The disclosure provides a motor with a deceleration mechanism capable of suppressing disengagement of gears even when a large external force is applied to an output shaft. A backup member 70 maintaining engagement between a pinion gear 61 and a helical gear 62 is provided on a side of the pinion gear 61 opposite to the side of the helical gear 62 in a gear case 20. Thus, even when a large external force is applied to the output shaft, disengagement of the gears (disengagement of the pinion gear 61 and the helical gear 62) can be suppressed. Therefore, damage to the pinion gear 61 and the helical gear 62 (deceleration mechanism 60) can be prevented for a long period of time, and consequently the life of the motor 10 with the deceleration mechanism can be extended.

The apparatus for cleaning a surface comprises a housing for accommodating an object whose surface is to be cleaned, a wiper driving actuator adjacent the surface to be cleaned, the wiper driving actuator comprising an at least partially closed loop adapted to rotate about a longitudinal axis of the housing, and at least one wiper assembly operable by the wiper driving actuator to move along the at least partially closed loop and having a first end that is attached to the wiper driving actuator, the wiper assembly being movably mounted in the housing such that, in use, a constant distance is kept between the wiper assembly and the surface to be cleaned.

A windshield wiper assembly for a dual sweep angle and indexable wiper system is provided. The system includes a wiper motor and a wiper arm for sweeping a surface of a windshield coupled to a first eccentric, the first eccentric comprising a primary eccentric and an indexable eccentric plate, wherein the indexable eccentric plate determines an eccentric offset of the wiper arm coupled to the first eccentric. The system further includes an output wiper shaft coupled to the wiper arm, a second eccentric coupled to a cam shaft, and a link coupled to the first eccentric and the second eccentric, the link having a first effective link arm length between the first eccentric and the second eccentric for driving the first eccentric to operate the wiper arm when operated in a first direction.

A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.

A windshield wiper system (WWS) is provided and includes a wiper blade assembly drivable along a first sweep angle, an internal wiper trigger disposed to move with the wiper blade assembly, a measurement system configured to monitor a position of the internal wiper trigger from which a corresponding position of the wiper blade assembly relative to the first sweep angle is measurable and to output a sweep angle feedback signal corresponding to monitoring results and a controller. The controller is receptive of the sweep angle feedback signal.
