Definitions

  • the invention relates to a windshield wiper device, in particular for motor vehicles, according to the preamble of the independent claims.
  • a wiper arm carries a wiper blade which is able to slide over the windshield of the motor vehicle and wipes the moisture off the windshield with the aid of a wiper blade arranged on the wiper blade and thus for a clear view through the windshield or rear window of the Through the vehicle.
  • a windshield wiper device which has a wiper arm which is driven by means of two cranks which are articulated on the wiper device and thus executes a lifting-swiveling movement.
  • One of the cranks forms an eccentric bearing.
  • a drive unit which is often designed as an electric motor, and at its second end the wiper arm is articulated in a wiper arm receptacle.
  • the second crank is blind, meaning no drive, attached to the windshield wiper device and serves as a handlebar, so that the wiper arm is guided on a defined path.
  • wiper arms can only be arranged with difficulty by concealing a covering.
  • the windshield wiper device according to the invention with the features of the main claim has the advantage that a second crank as a handlebar can be dispensed with by a second drive unit for determining the movement between the eccentric bearing and the wiper receptacle. Furthermore, such a device can be more easily concealed by a cover, for example the hood of the motor vehicle. In addition, the stroke of the wiper arm can be varied more, and in particular also increased. This wipes better in the peripheral areas of the window, which results in a direct improvement in the driver's view.
  • a handlebar which includes a fixed angle with the first wisher arm receptacle. This handlebar can serve as a dynamic counterweight to the wiper arm, for example, and in this way relieve the load on the second drive unit.
  • a further wiper arm for example a wiper arm on the driver's or passenger's side, can be driven in a simple manner on the windshield of a motor vehicle.
  • the eccentric bearing is designed as a simple crank and cranks with a very high ability can be manufactured. This is particularly advantageous because very high forces and torques have to be transmitted in the eccentric bearing.
  • the windshield wiper device according to the invention with the features of claim 6 has the advantage that the determination of the movement between the eccentric bearing and the wiper arm holder is achieved by a link which includes a fixed angle with the wiper arm holder. In this way, the relatively complex stroke-swivel movement can be achieved very easily.
  • the handlebar is mounted in a guide.
  • the movement profile of the wiper arm can be defined by a simple guide. It is particularly advantageous here if the guide is curved. This results in a particularly smooth movement of the wiper arm over the window.
  • FIG. 1 shows a windshield of a motor vehicle with an inventive
  • Windshield wiper device Figure 2 is a schematic representation of a windshield wiper device according to the invention
  • Windscreen wiper device from Figure 2 and Figure 4 shows a variation of the invention
  • Windscreen wiper device for two wiper arms.
  • FIG. 1 shows a windshield wiper device 10 according to the invention and a windshield of a motor vehicle 12 in a schematic illustration.
  • the windshield wiper device 10 is designed by means of a wiper arm 14 and a wiper blade 16 attached thereto in such a way that the wiper blade 16 is able to slide over the windshield 12 in a stroke-swivel movement.
  • the windshield wiper device 10 is shown in detail in FIG. It essentially consists of one Eccentric bearing 18, which is designed as a crank and can be driven by a drive unit, not shown here.
  • This first drive unit is fixedly attached to the vehicle body or the vehicle window 12 and is designed in such a way that the crank 18 performs an oscillating movement around its first end 20 during operation.
  • the other end 22 of the eccentric bearing 18 carries a further drive unit 24, on the output shaft 26 of which a wisher arm receptacle 28 is fastened in a rotationally fixed manner.
  • This further drive unit 24, like the first drive unit, is designed as a reversible electric motor which causes the Wiacherarmaufnähme 28 to oscillate.
  • a handlebar 30 is arranged at a fixed angle to the Wiseherarmaufnähme 28. This moves with the wiper arm receptacle 28 such that its free end facing away from the wiper arm receptacle 28 describes an arc.
  • This link 30 can carry a counterweight or even serve as a counterweight to the wiper arm 16 in order to reduce the torque requirement in the further drive unit 24.
  • FIG. 3 shows a variation of the invention.
  • an arcuate guide 36 is arranged which guides the end of the link 30 facing away from the wiper arm receptacle 28.
  • a pendulum movement of the eccentric bearing 18 around its first end 20 is also a pendulum Stroke movement of Wiseherarmaufnähme 28 and thus the wiper arm 14 with the wiper blade 16 causes.
  • FIGS. 4a to 4e Various positions of the windshield wiper device 10 are shown in FIGS. 4a to 4e.
  • the windshield wiper device is in the lower reverse position. In this, the effective wiper arm length determining the stroke is minimal.
  • FIG. 4b the windshield wiper device 10 is in a first central position. The effective wiper arm length is maximum in FIG. 4c. This is exactly the case when the eccentric bearing 18 and the wiper arm receptacle 28 and thus the wiper arm 14 are in the extended position.
  • FIG. 4d the wiper arm receptacle 28 with the wiper arm 14 is rotated further upward by the further drive unit 24, but the effective wiper arm length is reduced by a bent angle between the wiper arm receptacle 28 and the eccentric bearing 18.
  • the wiper arm is in the upper reverse position. The stroke is minimal again here. This can go so far that the eccentric bearing 18 and the wiper receptacle 28 are in the top position.
  • FIG. 5 shows a further variation of the windshield wiper device 10 according to the invention.
  • a connecting rod 32 is fastened here to the handlebar 30 and serves a further link 38 of a further windshield wiper device 40.
  • This further windshield wiper device 40 itself does not need to be designed as a windshield wiper device 10, ie with an eccentric bearing 18.
  • the further wiper arm holder for example, only performs a pendulum movement, as is often the case with the driver Wiping areas on windshields of motor vehicles with two wiper arms is the case.
  • the windshield wiper device 10 and the further windshield wiper device 40 can also be arranged in reverse, so that the windshield wiper device on the right in FIG. This should be chosen especially against the background of right- and left-hand drive vehicles.

Abstract

L'invention concerne un dispositif d'essuie-glace (10) destiné en particulier à un véhicule automobile. Ce dispositif comprend un premier groupe d'entraînement qui sert à entraîner un premier côté d'un support excentrique (18) et un premier élément de réception de bras d'essuie-glace (28) qui est articulé au second côté du support excentrique (18). Un second groupe d'entraînement (24) ou bien une bielle (30) pourvue d'un élément de guidage (36) servent à la détermination du mouvement entre le support excentrique (18) et l'élément de réception de bras d'essuie-glace.
