Definitions
- the invention is based on a hinge pin according to the preamble of claim 1.
- a fastening part is generally fastened to a drive shaft, to which a joint part is connected via a hinge pin.
- a wiper rod adjoins the joint part and a wiper blade is hooked into the hook-shaped end.
- the wiper blade comprises a generally multi-member support bracket system with intermediate brackets hinged to a central bracket, the ends of which are articulated to the claw brackets.
- the claw brackets at their ends hold a wiper strip on their head strip with their claws.
- the multi-part support bracket system and a spring rail inserted into the head strip enable the wiper strip to adapt to a curved windshield with even contact pressure when wiping.
- intermediate brackets or claw brackets can be omitted.
- the center bracket has claws with which it holds the wiper strip.
- a hinge pin made of plastic which has bearing areas with a smaller diameter at its ends.
- the pin is split between the areas, the split parts between the bearing areas forming an area with a larger diameter.
- the split parts can be compressed to the smaller diameter of the bearing areas, so that the hinge pin can be pushed through the bearing openings into the bracket that overlaps with its side cheeks.
- the hinge pin reaches its end position, the split parts spread elastically back to their starting position and fix the hinge pin between the inner cheeks of the inner bracket.
- the slots between the split parts form sensitive notches and greatly reduce the breaking strength of the joint pin. Furthermore, in the
- a two-part hinge pin consisting of an outer, radially deformable tubular sleeve and a rod arranged inside the tubular sleeve.
- Spreading elements are provided in the middle area between the tube sleeve and the rod, which expand the middle area of the tube sleeve to a larger diameter during assembly and thus cause the hinge pin to be axially fixed.
- a plastic piece or a noise-damping part is arranged between the bracket parts and the tubular sleeve.
- the hinge pin is complex to manufacture and difficult to assemble, since the individual parts of the hinge pin have to be aligned with one another and with the bracket parts. Furthermore, the tension that is exerted on the tubular sleeve by the expansion elements is retained in the assembled state in the tubular sleeve and can lead to permanent breaks during operation.
- the hinge pin is hollow and has an outer, closed peripheral surface. This avoids notches and increases the breaking strength of the joint pin.
- the areas adjoining the bearing areas which have a radially projecting cross-sectional contour, are elastically deformed and brought to a diameter which essentially corresponds to the diameter of the cylindrical bearing areas.
- the adjacent areas return to their starting position and fix the hinge pin in the axial direction. The tension generated during assembly in the hinge pin is completely or up to a desired one
- the adjoining area with the above cross-sectional contour can be provided between the bearing areas and / or at the ends of the hinge pin, two adjoining areas interacting for axial fixation. If the adjoining areas are arranged between the storage areas, two areas can merge seamlessly, for example in that a bead is provided between the storage areas, which can be divided both in the initial direction and in the longitudinal direction by sections with a smaller diameter.
- the protruding parts of the bead are expediently pressed radially inward during assembly by an assembly device with a conically offset bore through which the hinge pin is pressed, the inner contour of the hinge pin deforming accordingly elastically inward.
- the hinge pin is axially fixed by an adjoining area at its rear end in the mounting direction and an intermediate area adjoining on the other side of the bearing area.
- the middle area forms a bulge which tapers in the assembly direction in cross-section down to the cross-section of the bearing areas.
- the hinge pin can thus be driven through the bearing areas without tools.
- the bead is divided in the circumferential direction by areas with a smaller diameter and that the raised areas of the bead become narrower in a wedge shape towards the flatly tapering end.
- the wider end ensures a secure axial fixation.
- This formation of the bead is advantageously combined with an adjacent area at the end of the hinge pin, which is formed by a prefabricated collar, the end face of the hinge pin being closed.
- the bead can be produced in that, on the one hand, the material is reinforced in the area of the bead, and, on the other hand, that the hinge pin in the area of the bead has a bulge when it is produced with approximately the same material thickness.
- the hinge pin in the area of the bead has a bulge when it is produced with approximately the same material thickness.
- there is a great radial elasticity of the hinge pin since the length of the hinge pin can change and overstressing of the fiber adjacent to the cavity is avoided if the diameter increases the bead shrinks.
- a similar effect is achieved if the radially projecting cross-sectional contour deviates from the circular shape and runs partly inside and partly outside the cylindrical base surface of the bearing areas. In this case, the inner parts of the
- the adjacent areas provided at the ends of the hinge pin can be designed in cross-section as well as the adjacent areas lying between the bearing areas, with the possibility of influencing the adjacent areas at one end or at both during assembly by suitable tools To form heat.
- the hinge pin can be expanded conically from the inside.

- a wiper blade 10 comprises a bracket system with a center bracket 14, an intermediate bracket 16 and claw brackets 18 which Holding claws 20 hold a wiper strip 26 and guide them over a windshield 28.
- the wiper blade 10 is articulated on a wiper rod 12 which engages between two side cheeks 22 of the center bracket 14 and comprises a hinge pin 24 (FIG. 1).
- the brackets 14, 16, 18 of the bracket system are connected to one another in an articulated manner by a hinge pin 32, 62 being inserted through bearing bores 56 in the side cheeks 22 of the brackets 14, 16, 18 inserted one into the other.
- 2 shows a section through an articulation between the central bracket 14 and the intermediate bracket 16.
- a plastic part 30 is provided between the brackets 14 and 16, which reduces wear and noise between the brackets 14, 16.
- the hinge pin 32 has a cavity 34 which is open at the ends. Furthermore, it has at the ends two bearing areas 36 and 38, between which an adjacent area 40 with a radially projecting cross-sectional contour is arranged. This area 40 is formed by a bead 42, the
- End faces interact with the inside of the intermediate bracket 16 and thus axially secure the pin 32.
- Fig. 5 shows the assembly of the hinge pin 32, which has a closed end in this embodiment, which is seen in the mounting direction 48 behind.
- the hinge pin 32 is pressed through a shaped piece 50 which has a conically offset bore 52. Due to the smaller diameter of the bore 52 at the end 54 of the fitting 50, the radially projecting cross-sectional contour is pressed radially inwards onto the diameter of the cylindrical bearing regions 36, 38 or the bearing bores 56, so that it can be mounted through the bearing bores 56.
- the elastically compressed area 40 spreads and causes the axial fixation between the inner side cheeks 22 of the intermediate bracket 16. It is expedient for the adjacent area 40 to have a run-on slope 74, at least in the mounting direction 48.
- the areas 64, 66 adjoining the cylindrical bearing areas 36, 38 are arranged with a radially projecting cross-sectional contour at the ends of the articulation pin 62. In principle, they can be designed similarly to the adjoining area 40 in FIG. 2. Here, too, it is expedient for at least area 66 to have a run-up slope 76 in the mounting direction 48.
- the areas 64, 66 can interact with one another (FIG. 3) or individually with a central area 40 between the bearing areas 36, 38 for axial fixation (FIGS. 4 and 10).
- the adjoining areas 40, 64 on both sides of the storage area 36 located at the rear in the mounting direction 48 are expediently selected.
- Collars 78 form the area 64 lying at the end and, on the other hand, the bead 42 between the bearing areas 36, 38 taper in the mounting direction 48 to the cross section of the bearing areas 36, 38 (FIGS. 4 and 10).
- the hinge pin 32 can be driven into the brackets 14, 16 without a special shaped piece 50.
- the bead 42 according to FIG. 10 is divided in the circumferential direction by areas 44 with a smaller diameter, which widen in the mounting direction 48, so that the raised areas of the bead 42 become narrower in a wedge shape toward the flatly tapering end.
- the areas 64 and 66 provided at the ends of the hinge pin 62 can be during or after assembly of the hinge pin 62 are formed by tools 68 and 70 under the influence of heat.
- the tool 70 has a conical extension, as a result of which the cavity 34 is expanded in a conical manner at its end.
- the area 64 is formed by a stepped tool 68 or is formed by a corresponding, prefabricated collar 78, which axially cooperates as a counter bearing with the area 66 at the opposite end of the hinge pin 62.
- the bead 42 does not have to extend over the entire circumference of the hinge pin 32 and over the entire length between the bearing areas 36, 38 as shown in FIGS. 6 and 7. It is sufficient if it is interrupted by areas 44 in the circumferential direction (FIGS. 8, 9 and 10) or areas 46 in the axial direction (FIG. 13).
- the cross-sectional contour 58, 60 of the adjacent regions 40, 64, 66 deviates from a circular shape and runs partly inside and partly outside the cylindrical base of the bearing regions 36, 38.
- the cross-sectional contour 58 is oval while the cross-sectional contour 60 is polygonal.
- the hinge pin 32 has the peculiarity that it is closed at both ends and has a vent opening 72 for venting the cavity 34. Furthermore, the cavity 34 has a bulge 80 in the region of the bead 42, so that the hinge pin 32 has a largely uniform material thickness axially. Through the bulge 80, the hinge pin 32 is both in the outer fiber and in the Fiber to cavity 34 stressed during assembly so that cracks in this area are avoided.
