     FIELD OF THE INVENTION The invention relates to vehicle engineering and relates to the design of a car wiper. The purpose of the invention is to increase the operational reliability by increasing the force of pressing the wiper blade to the windscreen to be cleaned.
    Fig. 1 shows a windshield wiper element, bottom view in Fig. 2 is section A-A in Fig. 1, fig. 3 shows the thrust angle as a separate part, which is influenced by the pressure element, in perspective view; figure 4 is an embodiment
    stop angle in the form of a bent end of the holder in axonometry.
    The wiper element of the car contains the holder 1, which
    connected to the head 2 by means of the housing 3. The area of the head 2 is closed by a cap 4 having the possibility of hinge movement relative to the housing 3 by means of two semi-axes 5,
    mounted with the possibility of movement g of the slot x 6 of the body 3. The holder 1 is fastened to the body 3 by means of two rivets 7.
    The housing 3 has a U-shaped cross section and consists of two parallel diameter spring 29. The protrusion 28 provides the centering of the spring 29 of the slot the end of the last, opposite protrusion 28, the spring is not kept perpendicular to the plane of the rod 17. The end of the spring 29, which is not centered by the protrusion 28, rests on the core of the limiter in the form of a flat part 30, having an i-shaped cross section, which consists of two parallel walls 31 interconnected by a crossbar 32 located perpendicular to this 171 The last cuts the crossbar 32 thanks to the slot 33, made in the crossbar. The crossbars 32 of two flat parts 30, interacting with two springs 29, rest on the first shelf 23 of the corner 22. The walls 31 of the flat parts 30 are located one from another at a distance equal to the outer diameter of the spring 29, so that they block the spring 29 in the direction perpendicular to the t 17. The springs 29 operate in compression and create a force between the first shelf 23 of the corner 22 and the hinge axis 18. This force creates a moment which, when the head is stationary (as it is connected to the output shaft), tends to cause the holder 1 to rotate direction pok -bonded arrow F in Figure 2. This moment is the force that allows the wiper blade to be pressed against the windscreen during operation of the wiper. The zone a of the edge 17, adjacent to the axis 18, forms an abutment limiting the angular deviation of the head 2 relative to the housing 3 in the direction of the arrow F, while the area b of this edge forms an emphasis, limiting the angular deflection of the head 2 in the opposite direction, and the area It plays the role of an emphasis when it is necessary to release the wiper relative to the windshield. In the latter case, the edge is clamped in the zone in the sleeve 11, a bending force acts on the pull 17, which is even more significant the stronger the user effort and the spring force, which at this moment is summed up with the user effort. The t he 17 has a significant bending resistance, since it is given a greater height by positioning it from both the spring and the spring 29 of the spring. T he 17 can be made more thick, if necessary. This design avoids bending deformation when the holder is released relative to the windshield. To prevent the spring 29 from bending, a guide, in the form of a circular cross-section 34, is provided inside it, the diameter of which is slightly smaller than the internal diameter of the spring 29. During movement of the body 3 relative to the head, the double side 17 moves towards the body 3 and slides freely through slots 33 the flat parts 30 and the holes 21 of the flange 23 of the corner 22. During these movements, the slope of the center line of the string 17, i.e. The axis of the spring 29 relative to the crossbar 9 of the housing 3 varies slightly. The proposed wiper element is simple to implement, since the angle 22, tons of hectares 17 and the flat part 30 can be obtained by simply stamping sheet materials. The installation of the wiper element is carried out as follows. First, the holder 1 and the body 3 are mounted by riveting, then the head 2 and the rod 17 are mounted by means of the axles 18, after which the springs 29 and their guides 34 are mounted against the buckling and mounted on the ends of the springs 29 that are not included contact with protrusions 28, flat parts 30, moving glands 17 into slots x 33. Install angle 22 into housing 3, moving shelf 24 between projections 26 and crossbar 9 of housing 3 until the shelf 33 stops against projections 26. Then the free ends of two g 17 are inserted into the, two holes 21 of the flange 23 of the corner 22 and set 29 zhiny compression pressure on the axis 18 until the recess of the sleeve on January 1 will not enter the openings provided in the walls 8 for the pivot shaft 10, whereupon this set ensures retention of the entire assembly together. Thus, the installation and manufacture of the proposed glass element is simple. This element allows to eliminate any damage caused by deformation. The use of an independent corner 22 of the side walls 8 interconnected by a crossbar 9. The walls 8 of the housing 3 carry a cylindrical hinge 10 placed between the head and the housing with the possibility of a hinged movement relative to the housing. The hinge axis 10 is installed perpendicular to the walls 8 in that part which is the most distant, on the one hand, from the holder 1 and, on the other hand, from the crossbar 9. The head 2 has a sleeve 11 with an undercut that intersects the hinge axis 10, containing a hemispherical head 12 at one of its ends, and flattened out by compression at its other end 13, to ensure its fixation. A sleeve is mounted on the sleeve 11, having two fork-shaped ears 14 and 15, each of which is formed by two parallel ears 16, between which one of the ends of the ends 17 is located, preferably having a rectangular shape. The mounting of the rod 17 and the two ears 16 is realized by means of a hinge axis 18, forming a cylindrical hinge between the rod 17 and the head 2 and parallel to the axis of the hinge 10. The head 2 has a recess 19 for mounting the head on the output drive shaft (not shown) of the wiper element . The output shaft is driven into rotation in alternating opposite directions by an appropriate mechanism. The head is fixed to the output shaft by means of a nut, which is screwed onto the end of the shaft. The hinge axis 18 and the undercut 19 are located on different sides of a plane passing through the axis of the hinge 10 and the perpendicular crossbar 9. The crossbar 9 is bounded on the right side of the hinge 10 by the transverse edge 20 located to the right of the hinge axis 18. The cap 4 allows you to deflect the head 2 relative to the housing 3 and the installation nut, which secures the head 2 on its output vape, in addition, in addition, the cap 4 closes the cylindrical hinges corresponding to the axis of the hinge 10 and the axis 18, and not closing the crossbar 9, n broken at the level of the transverse edge 20. Two ti gi 17, interacting with two fork-shaped ears 14 and 15, are made identical. One end of each cable 17 pivots around the axis 18, and the other end is located in the hole 21, with a wavelength in the stop angle 22. The corner 22 has a first shelf 23 in which two identical holes 21 are made parallel to the axis, and a second shelf 24 which ends with a bend 25, made along the edges of the flange 24 opposite to the joint zone of the two shelves 23 and 24. The bend 25 is parallel to the first shelf 23 of the corner 22. The side walls 8 of the housing 3 contain two extrusions forming identical protrusions 26 between the walls of the housing 3 ( at In this case, each wall 8 has one protrusion 26. In a section in a plane parallel to the crossbar 9 of the housing 3, the protrusions 26 have a triangular shape. The maximum of their relief is located in the zone closest to the axis 18. The punching due to which protrusions 26 are formed is performed to avoid the formation of tearing of sheet material forming the walls 8 of the housing 3. The protrusions 26 are less than the height of the walls 8 and each of them has the shape of a straight prism with a triangular base, the faces of which are perpendicular to the crossbar 9 of the housing 3. The projections 26 does not reach the plane of the crossbar 9, the second shelf 24 of the corner 22 is installed in the gap between the projections 26 and the crossbar. The height of the bend 25 is such that thanks to it, the corner 22 is wedged between the crossbar 9 and the adjacent edge of the protrusion 26. The first shelf 23 of the corner 22 rests with its two edges adjacent to the walls 8 of the housing 3, on the verge of maximum relief of the protrusions 26. Each ha 17 is made in its central zone with a rectangular slot 27, the larger side of which is located more parallel to the larger side of the rail 17. On the smaller At the side of the slot 27, which is closer to the axis 18, there is a protrusion 28 formed by a triangular top, which forms a relief in the slot 27. Inside the latter, a helical set is installed; The length of the slot 27 is equal to the length of the spring 29 in a free state, and the width of the slot 27 is at least externally71
    the holder 1 makes it possible to realize the protrusions 26 with a small relief, since the support of the shelf 23 on the protrusions 26 is made along a large length. In addition, the corner 22 may be made of a relatively thick sheet material, and the loads to which the shelf 23 is subjected are distributed over the supports of the corner 22 without any deformation. 4 / J mb n J / D V // //.
