Definitions

  • Wiper arm in particular for cleaning windows on motor vehicles
  • the invention is based on a wiper arm which is used in particular for cleaning windows on motor vehicles and which has the features from the preamble of claim 1.
  • a wiper arm is already known, the fastening part of which is not produced in a die casting process, but is formed from a sheet metal.
  • the fastening part essentially consists of a single flat plate, on the side of which cheeks are raised and which is deep-drawn in the area of the bore for the wiper shaft to form a collar surrounding this bore.
  • the collar tapers according to a conical fastening section of the wiper shaft.
  • the sheet metal fastener outlined does not meet the requirements for dimensional stability.
  • DE-OS 3926 714 also shows a wiper arm with a fastening part made of sheet metal.
  • the fastening part has an upper sheet metal section and a lower sheet metal section connected in one piece to it and lying approximately parallel to it, which are supported against one another along the outer contour which can be seen when looking at the wiper arm in the direction of the axis of the bore via side walls raised by the one sheet metal section.
  • the upper sheet metal section is considered to be the sheet metal section which is further away from the disk than the other sheet metal section when the wiper arm is located above a pane.
  • the invention has for its object to develop a wiper arm with the features from the preamble of claim 1 so that the stability of the fastening part is still improved.
  • a wiper arm which has the features from the preamble of claim 1 and in which, according to the characterizing part of claim 1, a sheet metal section around the bore at a distance from the outer contour of the bore when viewed in the direction of the axis of the bore Fastening part is supported against a flat side of the other sheet metal section. While in the known fastening part with an upper plate section and a lower plate section, these two sections are axially supported against one another only via the side cheeks on the outer contour of the fastening part, while only a wedge effect is achieved by the collar around the bore, is close to a wiper arm according to the invention there is full axial support on the bore. This is achieved in a simple manner in that one sheet metal section is supported on a flat side of the other sheet metal section.
  • a wiper arm according to the invention can be found in the subclaims.
  • a plurality of sheet metal sections of the fastening part which are connected to one another in one piece are folded such that they lie directly flat on one another and at least twice the material thickness is present around the bore.
  • Such a fastener is particularly easy to manufacture because the material deformations are limited.
  • a sheet metal section viewed in the direction of the axis of the bore, advantageously has the outer contour of the fastening part.
  • the other sheet metal section can be much smaller, it is only important that it is present in the area of the bore.
  • the upper sheet metal section preferably has the outer contour of the fastening part.
  • two sheet metal sections of the fastening part are folded around an edge located behind the bore and extending transversely to the longitudinal direction of the fastening part.
  • two sheet metal sections of the fastening part are folded around a longitudinal side edge.
  • a wiper arm in which a second sheet metal section is folded around the one longitudinal side edge of a first sheet metal section and a third sheet metal section around the opposite longitudinal side edge of the first sheet metal section appears to be advantageous. In this way, rounded longitudinal edges of the fastening part are obtained on both sides.
  • the second and third sheet metal sections preferably cover, transversely to the longitudinal direction of the fastening part considered, each about half of the first sheet metal section.
  • the second sheet metal section is widened in the area of the hole, in particular up to the edge of the first sheet metal section, while the third sheet metal section becomes correspondingly narrower or has completely disappeared.
  • the second sheet metal section and the third sheet metal section can engage in dovetail-like fashion on their end faces. It is conceivable to fold two sheet metal sections onto one another, which are completely identical to one another at least in some areas. When looking at the fastening part perpendicular to the direction of the axis of the bore, one would see the end faces of these two sheet metal sections.
  • the fastening part would be very sharp in the area of these free end faces. It is therefore provided in accordance with claim 13 that the sheet metal section, which has the outer contour of the fastening part, has a raised cheek at the edge, the height of which corresponds to the total thickness of the sheet metal sections lying one on top of the other and which, viewed perpendicular to the axis of the bore, covers the end face of another sheet metal section.
  • a folded edge between two sheet metal sections extends only to a plane which, passing through the axis of the bore, extends perpendicular to the longitudinal direction of the fastening part. Behind this level, the outer contour of the fastening part can then easily be formed by a circular arc, the center of which lies on the axis of the bore.
  • a second sheet section with an opening around a first longitudinal side edge and a third sheet section with an opening around a second longitudinal side edge of a first sheet section are folded.
  • the sheet metal sections are folded so that the second sheet metal section on the first Sheet metal section and the third sheet metal section rests on the second sheet metal section.
  • the first sheet metal section should be the sheet metal section that extends to the articulation point of an articulated part and has the means for articulating the articulated part on side cheeks that may be bent away from it.
  • a first and a second sheet metal section each with an opening and the second and a third sheet metal section with an opening are folded together.
  • the third sheet metal section can be located between the first and the second sheet metal section.
  • a fourth sheet metal section is additionally provided is folded with an opening around a transverse side edge of the first sheet metal section.
  • the fourth sheet metal section preferably lies directly on the first sheet metal section.
  • one sheet metal section can be supported by a raised edge against a flat side of the other sheet metal section.
  • This raised edge naturally has a distance from the outer contour of the fastening part. If the outer contour of the sheet metal section with the raised edge is smaller than the other sheet metal section, the raised edge can be located on the outer circumference of the corresponding sheet metal section.
  • an embodiment according to claim 25 appears to be particularly advantageous, in which the raised edge is located on the opening of the corresponding sheet metal section belonging to the bore.
  • the dimensional stability of the fastening part of a wiper arm according to the invention can be increased further in that sheet metal sections lying one on top of the other, at least in places, in addition to their folding edge are interconnected. A connection by spot welding or self-riveting is preferred.
  • the bore in the fastening parts of the wiper arms is also conical.
  • the adaptation of the bore to the tapered fastening section of the wiper shaft according to claim 27 is preferably obtained in that the bore within a sheet metal section, viewed in the axial direction, has a constant diameter and that the diameter from sheet metal section to sheet metal section is the same Dimension increases as the diameter of the conical section of the wiper shaft, on which the fastening part with the bore can be plugged. If you want to transmit higher torques, it is advantageous to strike a cone with a tool according to claim 28 on the stepped bore.
  • a tapered bore can also be machined or machined after the fastener is folded.

  • the wiper arm according to FIG. 1 has, as essential components, a fastening part 30, with which it is secured against rotation on a wiper shaft 31, a hinge part 32, which is pivotably articulated on the fastening part 30 via a hinge pin 33, formed from a sheet metal and into a cross section U- shaped shape is bent, a wiper rod 34 which projects at one end 35 into the hinge part 32 and is fastened to the hinge part with this end 35 and is bent at its other end to form a hook 36 in order to be able to be connected there to a wiper blade , and a contact pressure spring 37, which is located within the joint part 32 and which is hung on the one hand via a bracket 38 and a pin 39 on the fastening part 30 and on the other hand on the wiper rod 34.
  • the attachment points of the contact pressure spring 37 on the fastening part 30 and on the wiper rod 34 are selected such that the line of action of the contact pressure spring 37 in an operating position of the joint part 32, as shown in FIG. 1, is at a distance from the axis of the joint bolt 33.
  • the contact pressure spring 37 therefore tries to turn the hinge part relative to the fastening part in the direction of a window to be cleaned, and thereby ensures the necessary contact pressure of the wiper blade, not shown, against the window.
  • the fastening part 30 of the wiper arm according to FIG. 1 is also made from a sheet metal.
  • An upper sheet metal section 45, on which the screw 46 for clamping the fastening part 30 lies on a cone 47 of the wiper shaft 31, and a lower sheet metal section 48 can be distinguished from one another.
  • the two sheet metal sections 45 and 48 are in particular also flat in the area of a bore 49 with which they are placed on the cone 47 of the wiper shaft 31 and which therefore also tapers conically. If the fastening part 30 is viewed in the direction of the wiper shaft 31, the upper sheet metal section 45 covers the entire outer contour of the fastening part 30.
  • This outer contour is symmetrical to a longitudinal center plane 50 of the fastening part 30 and is composed of one Semicircle 51, the center of which lies on the axis of the bore 49, two straight sections 52 which start from the semicircle 51 and run somewhat towards one another, two adjoining sections 53 which run parallel to the central plane 50 and one which forms the front boundary and perpendicular to the central plane 50 extending section 54 together, but which has an incision 55.
