Definitions
- the present invention relates to a windshield wiper device, in particular for a motor vehicle, having a wiper motor which drives a wiper linkage via an output shaft, wherein the wiper linkage has at least one articulated rod which actuates a wiper arm, at whose end regions a respective ball disk is provided.
- the link rods used therein are mostly manufactured in two variants.
- the shells are injected into the one-piece link rod.
- the relatively long hinge rods must be inserted into the injection mold, which requires a lot of space and thus a very expensive injection molding tool.
- the articulated rod has a fastening range for the spherical shells, which is formed flattened, wherein the spherical shells are fixed or fixable in each case via at least one fastening means to the flattened attachment areas.
- a windshield wiper device is provided, the articulated rod of which can be easily made, namely a tube which can be deflected from an endless material to the desired length, so that only one deflection operation with a subsequent pressing operation is necessary to provide the flattened attachment regions.
- the use of a pipe brings a considerable weight advantage with constant load capacity of the joint rod with it. Thus, a weight reduction of more than 25% can be achieved.
- the spherical shells as well as the articulated rod can be prepared in advance in independent tools and can be variably mounted after production according to customer requirements.
- a retooling of a usually modular injection mold due to a change in the customer requirement with respect to the length of the articulated rod is no longer necessary, since this is simply the joint rod is shortened, then the end portions of the tubular profile are pressed and the spherical shells can be easily mounted according to customer requirements. Also, the assembly of the assembly of the windshield wiper device according to the invention is very easy to implement by simply mating the joint rod and spherical shells, which significantly reduces the installation costs.
- the articulated rod can be formed either by a pipe section or else by a flat material, in particular a sheet, which can be converted if necessary to a stiffer profile such as a U-profile.
- the fastening means may be formed by a screw, in particular a self-tapping screw or a rivet.
- the inventive design of the articulated rod also ensures that the spherical shells can be arranged in a simple manner to each other entangled.
- the attachment areas provided at the end regions of the articulated rod can be aligned with each other about the longitudinal axis of the articulated rod.
- a plurality of fastening means are provided for fastening the spherical shells to the flattened fastening regions of the articulated rod.
- the articulated rod is provided with at least one bend or buckling in a further embodiment of the present invention.
- the joint rod Due to the simple structural design of the joint rod, various spherical shells can be used. Thus, it is possible that at least one of the spherical shells has an opening on at least one side for receiving a hinge pin.
- At least one of the spherical shells is open on both sides.
- Figure 1 is a schematic representation of a windscreen wiper device according to the prior art
- FIG. 2 shows a hinged rod with enclosed spherical shells according to the prior art
- Figure 3 is a partial view of a windshield wiper device according to the invention with a joint rod according to the invention.
- the articulated rod 1 shows a joint rod 1 of a windshield wiper device according to the invention for a motor vehicle.
- the articulated rod 1 is designed in several parts and has in this embodiment at its end regions in each case a head element 2 and a connection profile 3, on which a flattened connection region 4 is formed.
- the head element 2 is fixed via two screw connections 5.
- connection profile is formed from a tube profile whose end regions are pressed in such a way that the tube walls touch and a flat connection region is formed on the otherwise tubular articulation rod 1.
- no hole is punched in this flat end to inject the plastic ball shells to inject.
- bores are introduced to connect the connecting region via a fastening means with the head element.
- a threaded connection is used in a further embodiment of the present invention. With such a screw, the step of introducing bores into the connecting region of the link rod 1 can be dispensed with.
