the electromechanical device to allow the visibility through the windshield of the motor vehicle in the event of rain or snow

摘要

an electromechanical apparatus is available by means of a switch (1), on the line (2) from a battery (3) allows the passage of current to a transceiver (4).the transceiver (4) trasmettente on cable (5).a servo mechanical (6) two pulses for the alternative movement in both directions of operation of its drive shaft (7) with reversal of motion given by two microinterruttori to end race (8and (9).the servomechanism (6) is axially on a supportive initial stretch of inner wall of a supporting structure (10) of the windshield (11) and composed and drives.a reciprocating with the shaft (7), a parallelogram device with variable geometry, set on the upper axial continuation.formed by a rod (12), centrally reach supportive from the same and regent on rotary joints (13 and 14), provided for the terminal.a pair of rods (15, 16) with the terminal on the other rotary joints (17 and 18) for connection to a top bar (19) with centrally supports a tree (20) engaged inan axial body (21) brought also supportive to axially load-bearing structure (10).said shaft (20), kept in position by contrast on the outer wall of the supporting structure (10) to a terminal (22), a cylindrical partdoor by a brush (24) with a rubber part (25).
