A work vehicle comprising: a cab, an inside of which is a cockpit, having a window portion; a vehicle body having a passage on a periphery of the cab; a front lateral wiper provided so as to be rotatable around a first axis and along the window portion, and rotating around a second axis that extends in a different direction with the first axis in a movement range between a normal position that is in contact with the window portion and a rising position separated from the window portion; and a passage fence extending along an outer edge of the passage. The passage fence is configured to open upward with penetrating the passage fence inwardly and outwardly, and a part of the passage fence has an opening that includes the movement range of the front lateral wiper.

A cab of a work vehicle includes a front windshield that extends in a vehicle width direction; front lateral windshields that extends diagonally rearward and is connected to both sides of the front windshield in the vehicle width direction via ridgelines, and a rear-end edge of each front lateral windshield extending in a vertical direction being gradually separated from the ridgeline of each front lateral windshield while extending downward; a front lateral wiper that is disposed so as to be rotatable around an upper axis that is disposed above each front lateral windshield and so as to be rotatable along each front lateral windshield; an upper drive device that is configured to reciprocally rotate the front lateral wiper around the upper axis between a rear position in and a front position.

A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.

The present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other. In addition, a size of the wipe range can be adjusted by controlling a pivot angle of the AS-side output shaft 83 in forward and backward directions.

A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.

A Power Head assembly includes a motor having a rotating shaft and a converter configured to convert rotational motion of the shaft to reciprocating linear motion. The Power Head assembly also includes a weatherproof housing configured to house the motor and an inner portion of the converter. The Power Head assembly also includes a receptacle configured to receive a windshield arm of the vehicle and a fastener configured to attach an outer portion of the converter to a windshield wiper blade directly or indirectly, causing the windshield wiper blade to reciprocate along the windshield wiper blade. The Power Head assembly also includes a controller control the motor of the Power Head assembly.

The invention relates to a device (2) for wiping a window of a motor vehicle, comprising a wiper blade (4) rotated by a drive shaft (6) which is arranged at the output of a motor assembly (8) capable of creating an alternating rotational movement of said drive shaft. The wiping device also comprises means for translating the motor assembly, and some of said drive means are supported by the drive shaft. In this way, it is the rotation of the drive shaft that translates the motor assembly. The invention also relates to a motor vehicle comprising such a wiping device and to a structural element, in particular a boot door, to which the device is attached.

The invention relates to a wiper arm device (100) for cleaning a vehicle window (1), with a wiper arm head (10) that can be at least indirectly connected by means of a wiper arm rod (22) with a wiper blade (5) at a first end region with a drive shaft (12) and a second end region lying opposite the first end region, wherein the wiper arm rod (22) is pivotably mounted on the side facing the wiper arm head (10) in a first pivoting axis (20). It is provided according to the invention that a spacer device (40) is arranged on the wiper arm rod (22), and designed to hold the wiper arm rod (22) a constant distance (a) away from the vehicle window (1).

The invention relates to a wiper arm arrangement (100) for cleaning a vehicle window (1), with a wiper arm head (10) that can be at least indirectly connected by means of a wiper arm rod (22) with a wiper blade (5) at a first end region with a drive shaft (12) and a second end region lying opposite the first end region, wherein the wiper arm rod (22) is pivotably mounted on the side facing the wiper arm head (10) in a first pivoting axis (20). The invention provides that the wiper arm rod (22) consist of two elements (26, 28), a first element (26) connected with the wiper arm head (10) and a second element (28) that can be connected at least indirectly with the wiper blade (5), and that the two elements (26, 28) be arranged so that they can pivot relative to each other in a second pivoting axis (30), wherein the second pivoting axis (30) is arranged essentially perpendicular to the first pivoting axis.

A work vehicle comprising: a cab, an inside of which is a cockpit, having a window portion; a vehicle body having a passage on a periphery of the cab; a front lateral wiper provided so as to be rotatable around a first axis and along the window portion, and rotating around a second axis that extends in a different direction with the first axis in a movement range between a normal position that is in contact with the window portion and a rising position separated from the window portion; and a passage fence extending along an outer edge of the passage. The passage fence is configured to open upward with penetrating the passage fence inwardly and outwardly, and a part of the passage fence has an opening that includes the movement range of the front lateral wiper.
