Description

-Scheibenwaschanlage-Windscreen washer system

Die Erfindung bezieht sich auf Scheibenwischanlagen von PKW'3 fUr Frontscheiben .The invention relates to windscreen wiper systems for passenger cars'3 windows.

Stand der TechnikState of the art

Scheibenwischanlagen bei Pkw's sind in bisheriger Form nur in radialarbeitender Form bekannt,die Wischfläche der Scheibe war bisher nur bis zu 84* zu reinigen.Windscreen wiper systems in cars have so far only been known in radial form, and the wiping surface of the windscreen could previously only be cleaned up to 84*.

NachteilDisadvantage

Der Nachteil der alten Systeme ist das sie meißt Schlieren verursachten,The disadvantage of the old systems is that they usually caused streaks,

einen schlechten Luftwiderstandsbeiwert hatten und nicht diehad a poor drag coefficient and did not have the gesamte Scheibenfläche reinigen konnten .entire window surface could be cleaned.

Das Regenwasser wird teilweise gegen den Fahrtwind gedruckt.The rainwater is partially pushed against the wind.

LösungSolution

Beseitigung der Mängel wird dadurch erreicht daß erstens diese Soheiben-Elimination of the defects is achieved by firstly, this so-called

wischanlage bis nahezu 100% der Scheibe reinigen da die Wischblätterwiper system to clean almost 100% of the window because the wiper blades in alle Ecken kommen.reach all corners.

Zweitens ist das System während des Betriebes Strömungsgünstiger alsSecondly, the system is more streamlined during operation than

das herkömmliche System, bei nicht Betrieb befinden sich die Wischerthe conventional system, when not in use the wipers are

unter der Motorhaube.under the hood.

Drittens kann das Regenwasser durch den drückenden Fahrtwind mittels der tangential wirkenden Wischerarme besser beseitigt werden als beim herkömmlichen System.Thirdly, the rainwater can be removed more effectively by the pressing wind using the tangentially acting wiper arms than with the conventional system.

BeschreibungDescription

Die Scheibenwischanlage besteht aus 2 tangentialen Wischerarmem2) die je auf den Laufwagen (4,5) mittels Drehgelenk (3) angebracht sind.Die beiden Laufwagen(4,5) sind durch Element (7) miteinander verbunden und werden mittels den Laufrollen (17) auf der Laufschiene (6) bewegt.The windscreen wiper system consists of 2 tangential wiper arms2) which are each attached to the carriage (4,5) by means of a swivel joint (3). The two carriages (4,5) are connected to each other by element (7) and are moved on the guide rail (6) by means of the rollers (17).

Die Laufschiene (6) befindet sich unter der aerodynamischen Kante der Motorhaube (25)The guide rail (6) is located under the aerodynamic edge of the bonnet (25)

Die Wischarme(2) sind wiederrum durch ein Gestängeill) miteinander verbunden, tan welchem sich eine Schneckenmutter(13) mit einem Drehgelenk (23a),als Gegenstück zur Schneckenschraube (16). befindet. Die Schneckenschraube (16) ist in Verbindung mit dem E-Motor(10) der mittels Drehgelenk(23b) auf dem Element (7) befestigt ist. Das Element (7) besitzt eine Antriebsverbindung (8) jnd ist durchThe wiper arms (2) are in turn connected to each other by a rod (13) on which there is a worm nut (13) with a swivel joint (23a) as a counterpart to the worm screw (16). The worm screw (16) is connected to the electric motor (10) which is attached to the element (7) by means of a swivel joint (23b). The element (7) has a drive connection (8) and is connected by

\ das Drehgelenk(8b) mit der Antriebsstange (31) verbunden.\ the swivel joint (8b) is connected to the drive rod (31).

J Der Antrieb(9) erfolgt durch den E-motor(26) der eine Verbindungsst.ange (27) betreibt und zweitens das Zahnrad(28) in das Zahnrad(2Gb) eingreif und den Verbindugsbolzen(29) synchron umgekehrt antreibt. Die Verbindungsstange(27) greift ebenfalls am Verbindungsbolzen(23) an jedoch mittels eines Drehgelenkes. J The drive (9) is provided by the electric motor (26) which operates a connecting rod (27) and secondly the gear (28) engages with the gear (2Gb) and drives the connecting bolt (29) synchronously in reverse. The connecting rod (27) also engages with the connecting bolt (23) but by means of a swivel joint.

Der Verbindugsbolzen(29) treibt die Verbindugsstange (30) wie o.g entgegengesetzt zur Verbindungsstange (27) an.Die Verbindung(31) zwischen Verb.stange(30) und der Antriebsstange(32) beschreibt eine Ellipsenform und wird durch eine Führungsschiene(34) in dem Deckel(33) Der Antrieb erscheint für diesen Arbeitsgang noch der Vorteilhafteste im Vergleich mit z.b einem Hubzylinder.The connecting bolt (29) drives the connecting rod (30) as above in the opposite direction to the connecting rod (27). The connection (31) between the connecting rod (30) and the drive rod (32) describes an elliptical shape and is guided by a guide rail (34) in the cover (33). The drive appears to be the most advantageous for this operation in comparison with, for example, a lifting cylinder.

Die Länge des Antriebssystems würde ungefähr die Hälfte der Scheibenfläche betragen und die Breite ungefähr die Hälfte der Länge betragen, z.b bei einer Scheibe von 1,8 m wäre die Länge des Antriebsystems 0,9 m und die Breite ca.0.45 m.The length of the drive system would be approximately half the disk area and the width approximately half the length, e.g. for a disk of 1.8 m the length of the drive system would be 0.9 m and the width approximately 0.45 m.
