Abstract

This invention relates to vehicle wiper designs and can be used to clean windshields of automobiles. The aim of the invention is to improve driving safety by cleaning the entire surface of the windshield. The wiper consists of brackets 1, brush 2, holder 4, leading sleeves 5, leading 6 and slave 17 levers, engines 7, U-shaped 8, which are attached hinged by the bottom end and the upper through the spring to the cabin panel. Leading 15 and driven 16 shchestorn fixed on the intermediate II and driven 12 sleeves, respectively. The gears are located above the upper flange of the I-ring 10 and are engaged. The driven arms 17 connect the driven gears 16 to the holder 4. The wiper operates as follows. Rotational movement from the engines 7 is transmitted through the sleeves 5 to the levers 6 connected to the intermediate sleeves 11. The sleeves 11 are rotated through the pinions 15 and 16 to the driven levers 17, ensuring their reciprocating movement, which in turn through the holder 4 transferred to the brush. 5 il.

Description

This invention relates to vehicle wiper designs and can be used to clean windshields of automobiles.

The aim of the invention is to improve driving safety by cleaning the entire surface of the windshield.

FIG. 1 shows a wiper, longitudinal section; in fig. 2 — node I in FIG. one; in fig. 3 - node II in FIG. one; in fig. 4 - wiper in axonometric projection; in fig. 5 - kinematic wiper diagram.

The wiper consists of brackets 1, a brush 2 mounted on one ends of the brackets 1 and placed on the windshield 3 of a vehicle (not shown), a holder 4 in which the second ends of the brackets 1 are attached, driving sleeves 5 mounted on the base of the glass 3 under the brush 2, the driving levers 6 connected by one ends with the bushings 5, the motors 7, attached to the bushings 5, by the U-shaped bracket 8, hinged by its lower end under the glass 3, inside which the rotating turns are placed with the possibility of rotation nye sleeve 5, the springs 9 connecting the upper end of the U-shaped bracket 8 with the base of the windscreen 3, H-bracket 10; intermediate 11 and 12 driven swivel sleeves mounted on the bracket 10 between its shelves 13 and 14, the leading gears 15, mounted on the intermediate sleeves 11 above the upper shelf 13 of the bracket 10, driven gears 16, fixed pa driven sleeves 12 above the upper shelf 13 of the bracket 10 which are in engagement with the driving gear 15, and the driven arms 17 connecting the holder 4 to the driven gears 16 and forming a triangle with the driving levers 6, in the vertex of which there is a bracket 10, and in the base there are glass 3. The driving arms Agi 6 with their second ends us with intermediate bushes 11.

The wiper works as follows.

The rotational movement from the motors 7 is transmitted to the sleeves 5, which in the bracket 8 rotates reciprocating 180 °. The rotation of the sleeves 5 through the levers 6 is transmitted to the sleeves 11. In this case, the rotation of the sleeves 5 provides movement with the levers 6 of the bracket 10 and the brush 2 along the entire surface of the glass 3 in the horizontal plane. In the process of reciprocating movement

the brushes 2, the rotation of the sleeves 11 through the gears 15 is transmitted to the gear 16, rotating on the sleeves 12. The rotation of the gears 16 is transmitted by the levers 17, ensuring their reciprocating movements along radii arcs equal to the projections of the levers 6

on the glass 3. As a result of this, a straight-line reciprocating movement of the holder 4 occurs, in which the ends of the arms 17 are movably fixed. This movement from the holder 4 is transmitted to the brackets 1,

rigidly connected to the holder 4, and further to the brush 2, which performs a rectilinear reciprocating movement on the glass 3.
