Definitions

  • the present invention relates to a windshield wiper device, in particular for a motor vehicle, having at least one wiper bearing attached to a vehicle body of the vehicle, in which at least one bearing shaft is mounted, on which a bearing plate is provided to receive and relay forces occurring in the wiping operation.
  • Such windshield wiper devices are generally known and usually have a wiper lever which, during operation, is moved in a swinging manner over the window of the motor vehicle.
  • a wiper arm which carries at its free end a Wscherblatt and is attached at its other end to the bearing shaft, which in turn protrudes from the body of the motor vehicle.
  • the attachment of the bearing shaft is usually carried out by a press fit, wherein the bearing plate is mounted either above or below the wiper bearing housing.
  • the connection between the bearing plate and the bearing shaft via a riveting process by Verkantvernietung or a Ringverstemmung be realized. It is thus a precise production of the connection region between the bearing shaft and the bearing plate necessary to prevent slippage of the bearing plate on the bearing shaft. This is associated with considerable manufacturing and assembly costs.
  • the bearing shaft and the bearing plate by a bent pipe section. This has the advantage that both straight and capped or curved bearing plates can be produced in a simple manner by the pipe section.
  • the pipe section may have at least one, in particular two or more bends.
  • the bent pipe section offers the possibility of generating wiper bearings with different variations of pipe rocker arms by bending them accordingly.
  • the known from the prior art bearing plate is realized by a provided on the bent pipe section straight section.
  • the weight of the windshield wiper device can advantageously be significantly reduced.
  • the adjustment of a crank radius of the pipe rocker arm can be done by varying the length and the angle of the respective pipe bends.
  • the pipe rocker arm can be adapted to various operating conditions of the windshield wiper device in a simple manner and the size of the crank radius and the wiping angle to be generated on a be fixed to an end portion of the bent pipe piece wiper lever on the windshield of the motor vehicle according to the application defined.
  • a knurled cone for attachment of the wiper lever to an end portion of the bent pipe section is in an embodiment of the present invention to the latter a knurled cone, in particular provided with a thread, wherein the knurled cone is formed either integrally with the pipe piece or as a separate component at the end portion of the pipe piece, in particular in the end region of the bent pipe piece can be inserted, attachable to the latter, in the end of the Ror committees screwed or can be applied by a forming process.
  • a ball pin which in turn is either formed integrally with the pipe piece, attachable to the end region in particular by a forming process, can be screwed or inserted into the pipe section.
  • the ball stud can be a simple ball stud or a double ball stud.
  • one or more recesses and / or indentations are provided on the pipe section in a further embodiment
  • Fastening means such as a Speednut, a C-clip, a snap ring, a retaining ring, a lock washer or the like can engage.
  • Figure 1 is a schematic representation of a wiper system according to the prior art
  • FIG 2 is an enlarged partial view of the wiper bearing according to Figure 1;
  • Figure 3 shows different variants of pipe rocker arms of a wiper bearing according to the invention.
  • Figure 4 shows different variants of inventive pipe rocker arms.
  • FIGS 1 and 2 show a partial view of a windshield wiper device 1 according to the invention for a motor vehicle with two mounted on a vehicle body of the vehicle wiper bearings 2.
  • the wiper bearings 2 each have a bearing shaft 3 is mounted.
  • a mounting portion 4 is formed on which a bearing plate 5 is mounted above lying to absorb forces and moments occurring in wiping operation and forward.
  • a knurling 6 is provided to support the non-positive and positive connection between the bearing shaft 3 and bearing plate 5.
  • the teeth of the knurling 6 take by means of non-positive and positive connection, the forces and moments arising in the wiping operation and forward them.
  • the bearing plate 5 is pushed onto the bearing shaft 3 until it comes into engagement with the mounting portion 4 of the bearing shaft 3 and comes to a stop 7 to the plant.
  • the processing tion of the bearing shaft 3, in particular the introduction of the knurling 6 is very expensive.
  • the production of the interference fit between the bearing plate 5 and the bearing shaft 3 requires a very precise and therefore costly processing.
  • the invention proposes not to perform the bearing shaft 3 and the bearing plate 5 as in the prior art, but to form one piece.
  • bent pipe section 7 assumes the function of the known from the prior art bearing shaft 3 and the bearing plate 5, wherein the bearing plate 5 is formed by a pipe section 7 formed in the straight section 8.
  • the pipe section 7, as well as in the prior art, the bearing shaft 3 is mounted in a bearing housing 9.
  • the pipe section 7 can have one, two, three or even more bends.
  • the knurling cone 6 produced in the prior art by material processing is replaced according to the invention by a knurling cone inserted at an end region of the pipe section 7.
  • This can either be formed integrally with the pipe section (see FIG. 4, right-hand embodiment) or attached as a separate component to the end region of the pipe section, in particular in the region of the bent pipe section or plugged onto the latter (see FIG. 4, left and center illustration).
  • a thread is formed in the centrally shown embodiment of the pipe section 7 according to FIG. 4 in the upper end region of the pipe section 7, into which the knurled cone can be impressed.
  • a ball pin 1 0 is provided at the opposite end of the knurled cone of the pipe section 7, as shown clearly in Figures 3 and 4, a ball pin 1 0 is provided. This is formed integrally with the pipe section 7 in the embodiment shown in Figure 4.
  • the pipe section 7 shown on the right in FIG. 4 is designed as a solid pipe.
  • the embodiments shown in Figure 4 left and center of the pipe section 7 are formed as hollow tubes, on whose the knurl cone opposite end portion of a ball pin 10 is inserted or inserted.
  • a double ball stud is provided on the end region of the pipe section 7 opposite the edge 6. To simplify the attachment of the double ball stud to the end portion of the pipe section 7, the latter is formed flattened.
  • the attachment of the pipe section can be made in the case in which the double ball pin is attached by, for example, riveting or welding or other fastening methods known in the art.
  • one or more recesses 12 are also provided. These are used to insert fastening means such as a speed groove, a C-clip, a snap ring, a snap ring, a lock washer or the like therein to position and fix the pipe section 7 in the bearing housing 9.
