Definitions
- the invention relates to a cast fastening part for a windshield wiper arm, with a through opening for a bearing bush and a receptacle for a retaining pin.
- Such a fastening part serves to connect a wiper arm to a drive motor.
- a tension spring is mounted which presses the wiper arm 'against the windshield to be cleaned.
- the fastening part which is a casting, was drilled after casting in order to obtain a through hole for the bearing bush and another hole for receiving the retaining pin.
- a disadvantage of this manufacturing process is the high effort, which is connected on the one hand with the machining of the fastening part and on the other hand with compliance with the required tolerances for the two bores.
- the fastening part with the features of claim 1 has the advantage that no machining is required to create the receptacle for the retaining pin.
- the groove serving as a receptacle is created during the casting process.
- the retaining pin only has to be later inserted into the groove and caulked in it.
- the surface of the through opening is produced by direct molding of a molded part. Machining is therefore no longer required for the production of the through opening, and the same advantages result as in the absence of machining for receiving the retaining pin.
- 1 shows a complete wiper arm from below
- 2 shows a side view of the wiper arm from FIG. 1
- FIG. 3 shows the fastening part used in the windshield wiper arm from FIG. 2 in a broken, partially sectioned view
- FIG. 4 shows the fastening part from FIG. 3 in a view from below
- FIG. 5 shows, in an enlarged view, a section through the fastening part along the plane V-V of FIG. 3.
- FIG. 1 and 2 show a wiper arm which consists of a fastening part 10, a sheet metal part 20 and a bracket 18 which is fixedly connected to the bending part.
- the fastening part 10 has a receiving bore 26, by means of which it can be connected to a windshield wiper drive (not shown).
- the sheet metal part 20 is rotatably fastened to the fastening part 10 by means of a bearing bush 28 which is inserted into a through opening 14.
- a tension spring 22 is attached, which is suspended on a retaining pin 16 on the fastening part and serves to press the wiper blade against a pane to be cleaned via the extension arm.
- the fastening part which is a cast part, will now be described in more detail with reference to FIGS. 3 to 5.
- the through opening 14 is created by molding a suitable section of the mold in which the fastening part is cast. In this way, the required tolerances can be observed immediately, so that no post-processing is required, and the bearing bush 28 can be pressed directly into the through opening.
- the holding pin 16 is arranged in a groove 30 which is closed at both ends in the axial direction. This groove is also created by molding a suitable section of the mold, so that no post-processing is required. The retaining pin is then inserted into the groove 30, whereby it cannot slip in the axial direction since the groove is closed.
- the fastening part 10 is deformed via a deformation stamp (not shown) in the region of the groove in such a way that at least one lug 12 is produced which holds the holding pin 16 securely in its position.
- This caulking of the retaining pin offers an extremely effective securing of the retaining pin on the fastening part 10 and can also be accomplished with little mechanical effort.
