A replay plate 44 is set to have a vertically and horizontally symmetrical shape when a worm wheel 33 is viewed from its axial direction; the worm wheel 33 is provided with an accommodating concave portion 33g in which the relay plate 44 is housed so as to be recessed in the axial direction; and a part of a non-slidably contacting surface in a slidably contacting surface 44a of the relay plate 44, i.e., a non-slidably contacting surface S is covered with first and second fixing parts 35a, 35b that are provided around the accommodating concave portion 33g and protrude in a direction intersecting with an axial direction of the worm wheel 33, the non-slidably contacting surface being a surface with which the contact plate is not slidably contacted.

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.

This disclosure enables an assembly for driving an arm of a windshield wiper of a vehicle. The assembly includes a support structure in a housing that is secured against rotation relative to the housing. The support structure has an opening with a bearing surface, where the opening is configured to receive a boss of a worm wheel such that the bearing surface faces the boss of the worm wheel.

An actuator and a vehicle operation system with the actuator. The actuator includes a housing unit composed of a combination of internal components including a motor, a housing and a cover. A pair of terminals conveys external power to the motor. A terminal holder holds die pair of terminals. The terminal holder is accommodated in the housing unit as a sub-assembly separately from the housing unit.

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.

Disclosed is an aircraft windshield wiper system, having: a wiper arm; a reversible motor that drives the wiper arm, the motor including: a stator; a rotor configured to rotate relative to the stator; a forward shaft segment that is driven by the rotor and being rotationally connected to the wiper arm; an aft shaft segment that is driven by the rotor, the aft shaft segment including a forward end and an aft end; a ball nut that translates along the aft shaft segment from rotation of the aft shaft segment; a forward stop at a forward end of the aft shaft segment, configured to stop forward translational motion of the ball nut along the aft shaft segment; and an aft stop at an aft end of the aft shaft segment, configured to stop aft translational motion of the ball nut along the aft shaft segment.

The invention relates to a gear motor (1) for a motor vehicle wiper system including an electric motor (2) including a rotor (20) and a rotation shaft (22) fixed to the rotor, a reduction gear mechanism (3) including a worm/worm wheel system, a device for generating an axial load configured to offset axial play of the rotation shaft (22), including a retaining wedge (6) mounted in a sliding manner in a radial direction of said rotation shaft (22), said retaining wedge (6) exerting an axial load on the outer race of a ball bearing (5) configured to guide the rotation shaft. According to the invention, said retaining wedge (6) is arranged in an intermediate position between the seat (40) of the bearing support (4) and the worm (30) directly adjacent to the worm wheel (31), said axial load (Fa) exerted by the retaining wedge (6) on the outer race (51) of the ball bearing (5) being in the direction away from the worm (30).

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.
