Embodiment Construction

[0016] FIG. 1 shows a wiper device 10 with an output shaft 11 on which a crank 12 is mounted.

[0017] FIG. 2 shows the driven shaft 11 and the crank 12 after the driven shaft 11 has been inserted through the opening in the crank 12 . The output shaft 11 has a region 13 which protrudes above the crank 12 .

[0018] FIG. 3 shows the raised area 13 after the raised area 13 has been arranged snugly on the crank 12 . By arranging the protruding area 13 in close proximity, screw connections can be omitted in the future, which reduces the installation space required for the windshield wiper device 10 . Since the preparation of bolts, nuts and threads will not be required in the future, the price of producing and installing the wiper device 10 is more favorable.

[0019] The protruding area 13 can be provided tightly by crimping, for example by wobbling or rolling.

[0020] The output shaft 11 is provided with a bore 14 , wherein the bore 14 is configured conically. Due to the ho...

Abstract

The invention relates to a window wiping device, in particular for a motor vehicle, with a crank ( 12 ) mounted on an output shaft ( 11 ). In the previously known window wiping devices, the crank is screwed to the output shaft, with a certain amount of construction space being required for the screw connection. In the window wiping device according to the invention, the output shaft ( 11 ) therefore has a region ( 13 ) which protrudes over the crank ( 12 ) and can be placed onto the crank ( 12 ), thus reducing the amount of construction space required.

Description

technical field [0001] The invention relates to a windshield wiper device, in particular for motor vehicles, having a crank mounted on a driven shaft. Background technique [0002] In wiper devices known from the prior art, the crank is screwed to the output shaft. However, such screw connections require a certain installation space. Since the installation space available today is getting narrower, it is becoming more and more difficult to provide the space required for the wiper device. In addition, threaded connections also require a certain material and assembly expenditure. Contents of the invention [0003] The object of the present invention is to improve the aforementioned wiper device in such a way that the required installation space, material and assembly effort will be reduced in the future. [0004] The invention solves this proposed object by a windshield wiper device as described above, wherein, according to the invention, the output shaft has a region whi...
