摘要： 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.

摘要： A vehicle wiper device includes a first driving lever, a second driving lever, a first driven lever, a second driven lever, a first wiper arm, a first wiper blade, a second wiper arm, and a second wiper blade. The first driving lever is pivoted by a driving force of a first drive source. The second driving lever is pivoted by a driving force of a second drive source. A pivoting speed of the second wiper blade from a lower reversal position is set to be greater than a pivoting speed of the first wiper blade from a lower reversal position.

摘要： The present invention concerns a device for cleaning a sensor of a motor vehicle. The device in accordance with the invention includes means for simultaneous or sequential distribution via a distribution orifice (11) in a distribution nozzle (1) of a first fluid and/or a second fluid separately routed via a first admission channel (2) and/or via a second admission channel (3), respectively, to a common distribution chamber (10) in said distribution nozzle (1). It also includes means for moving said distribution nozzle (1) between a rest position and a deployed position, and these said means for moving the distribution nozzle (1) include means shared with the means for feeding the first admission channel (2) with the first fluid.

摘要： A wiper system for a machine is provided. The wiper system includes a first motor configured to operate a first wiper and a second motor configured to operate a second wiper wherein the first motor and the second motor are connected in a parallel configuration. The wiper system further includes a power source which is in electrical connection with the first and the second motors for energizing each motor to move the respective wipers. The wiper system includes a switch configured to simultaneously operate the first motor and the second motor in one of a high speed mode, a low speed mode, or a park mode. The wiper system includes an isolating circuit configured to isolate the first motor from the power source and allow the second motor to run independent of the first motor when the switch is set in the park mode and speed of the first motor is different from speed of the second motor.

摘要： A vehicular vision system includes a driver-side exterior mirror assembly, a passenger-side mirror assembly and an interior mirror assembly. The fields of view of the mirror reflective elements of the exterior mirror assemblies are adjustable by the driver via a respective actuator. The exterior mirror assemblies include respective cameras that each have a respective rearward field of view that supplements the field of view of the mirror reflective element when viewed by the driver of the vehicle. A video display is disposed behind the mirror reflector of an interior mirror reflective element such that displayed video images are viewable through the mirror reflector of the interior mirror reflective element. The video display includes a driver-side display portion and a passenger-side display portion that each display images derived from image data captured by the respective camera while not displaying images derived from image data captured by the other camera.
