Problems solved by technology

This means that the elements connected to each other in the drive train also have offset angles at the joints connecting them, although only a defined maximum offset angle is permissible for these joints, and thus the arrangement and realization of such windscreen wipers unit-related restrictions
In particular, the cross-steering devices used until now in windscreen wiper units have the disadvantage that the drive connection between one of the functional elements of the drive train driving the cross-steering device and the cross-steering device has to be designed in such a way that the The axis of motion of the functional element lies in a plane perpendicular or nearly perpendicular to the pivoting cantilever arm of the cross-steering device

Embodiment Construction

[0046] To simplify the explanation, the spatial axes run perpendicularly to each other, i.e. the X-axis, Y-axis and Z-axis are shown in Figures 1-3, and the X-axis and Y-axis are in the drawing plane of Figure 1, i.e. they define the The drawing plane, while the X-axis and Z-axis are in the drawing plane of FIGS. 2 and 3 and are defined by XZ coordinates.

[0047] The windscreen wiper unit normally operates in reverse motion as shown at 1 in the accompanying drawings, the windscreen wiper unit mainly comprises two wiper arms 2 and 3, one end of which is connected to the wiper shafts 4 and 5 respectively, And the other end of the arm carries the wiper blades 6 and 7 which are placed against the vehicle windscreen WS.

[0048] In Figures 1 and 2 the vehicle windshield is wiped and cleaned by means of a drive train generally indicated by 8 and by crank arms 4.1 and 5.1 arranged on and projecting radially from wiper shafts 4 and 5 The two wiper arms 2 and 3 can pivot opposite eac...

Abstract

Disclosed is a windshield wiper system for vehicles, comprising at least one wiper arm which is driven by a wiper motor via a drive train so as to perform an oscillating movement. At least one crosslink-type drive (18) encompassing two joint supports (19, 28) and at least two crosslinks (24, 25) which are connected to the joint supports (19, 28) via joints (22, 23, 26, 27) is provided in the drive train, a first joint support (19) being pivotable about a pin (20) that runs parallel to the axes of the joints (22, 23, 26, 27). One of the joint supports (19, 28) is connected to a functional element (12) of the drive train which drives the crosslink-type drive (18) or is driven thereby via another joint (29) in order to allow for an offset angle between the direction of travel of the functional element (12) and the pivot plane of the first joint support (19).

Description

technical field [0001] The invention relates to a windscreen wiper unit according to the preamble of claim 1 . Background technique [0002] Windscreen wiper units are known in various forms and in the simplest case comprise a wiper arm with a wiper blade which can be moved via a transmission The drive train is driven by an electric motor or a wiper motor, and pivots or reciprocates around a wiper shaft. In this case, the transmission system consists of several push-pull rods, which can be moved, for example, by a wiper motor crank in the longitudinal direction of the rods to and fro strokes, and via these push-pull rods, which are arranged on the respective wiper shafts A crank arm is for example operated for reciprocating movement of a wiper arm connected to a wiper shaft. [0003] Known are wiper units with two wiper arms which are operated via a drive train by a common wiper motor, and also in particular such unit - in which the wiper shaft is arranged and the wiper a...
