Abstract

The invention relates to wiper designs and can be used for cleaning windshields of vehicles. The aim of the invention is to improve driving safety by cleaning the entire surface of the windshield. The windshield wiper consists of brackets I, brush 2, holder 4, additional bracket 5 with sleeve 6, swivel axis 8, drive 9, parallelogram mechanism, bracket 19, support arms and a spring. The actuator 9 through the axis 8 causes the oscillating movement of the driving lever 10 with an inclined sleeve 11 associated with a parallelogram mechanism. The oscillatory movement of the inclined sleeve 11 causes the larallogram. Reciprocating mechanism to reciprocate. The bracket 12 transmits this movement through the bracket I to the shaft 2. 2. ill.

The invention relates to wiper designs and can be used to clean vehicle windshields.

The purpose of the invention is to increase the safety of movement by cleaning the entire surface of the windscreen.

FIG. 1 shows a device, a longitudinal section; in fig. 2 - the same, in axonometric projection.

The wiper consists of brackets 1, a brush 2 fixed on one end and placed on glass 3, a holder 4 in which the second ends of the brackets 1 are fixed, an additional bracket 5 with a sleeve 6 mounted on the panel 7 of the cab under the glass 3, swiveling axis 8, placed in the sleeve b, the actuator 9, connected to the rotary axis 8, the driving lever 10, connected at one end to the axis 8, the inclined sleeve And, attached to the second end of the driving lever 10, parallelogram mechanism, containing a bracket 12, connecting free to The ends of the upper 13 and 14 levers using hinges 15 and 16, connected with the lower 17 and 18 levers, which are interconnected by a transverse clip 19, supporting 20 and 21 levers, hinges 22 and 23 connected with the lower levers. The spring 24 is fixed by one end on the upper arm, and the other - on the lower arm.

The actuator 9 through the axis 8 causes oscillatory movement of the drive lever 10 s

an inclined sleeve 11, which drives the parallelogram mechanism. The bracket 12 transmits a reciprocating motion through the bracket 1 to the brush 2. As a result, the brush 2 moves along the windscreen 3 linearly horizontally, cleaning the entire surface of the windscreen 3.

Claims (1)

Invention Formula A windscreen wiper containing main brackets, a brush mounted on one end, a holder, an additional arm with a sleeve mounted on the cab panel under the glass, a drive connected to the pivot axis, a hinge parallelogram mechanism consisting of a bracket connecting the free ends upper arms pivotally connected to lower arms that are interconnected by a transverse lever, characterized in that, in order to increase traffic safety by cleaning the entire surface of the wind stack It is equipped with a driving lever connected to a drive with an inclined sleeve, through which one of said lower arms is passed with the possibility of simultaneous axial and rotational movement of support arms in it that are hinged to the lower arms, a bracket connecting the lower arms between them, and a spring fixed at one end on the upper arm and the other on the lower arm.
