Abstract
Viene proposto un dispositivo servente a tergere vetri di autoveicolo. Il dispositivo tergitore comprende un braccio del tergitore che azionato pendolarmente, e in più parti in direzione longitudinale, alla propria estremità libera reca una spatola di tergitura e dal suo movimento pendolare tramite una trasmissione a traslazione alternativa ricavato dal movimento di traslazione alternativa, sovrapposto, al movimento pendolare, della parte del braccio di tergitura esterna portante la spatola di tergitura, e la trasmissione a traslazione alternativa presenta un segmento dentato solidale al telaio, che è disposto concentricamente rispetto all'asse di pendolamento e con la sua dentatura ingrana la dentatura di un pignone, con cui è accoppiata ad articolazione eccentricamente una estremità di una asta di traslazione l'altra cui estremità è articolata alla parte esterna del braccio di tergitura. Per realizzare una trasmissione a traslazione alternativa silenziosa e senza giuoco una delle due dentature presenta almeno due file di denti reciprocamente affiancate delle quali una è fatta di un materiale relativamente indeformabile e l'altra è disposta deviabile elasticamente, e la dentatura dell'altra fila di denti guardando in direzione dell'asse di pendolamento, almeno in un piano che lo interseca è più grande in ragione di circa il gioco massimo ammesso fra le due dentature, rispetto alla dentatura delle file di denti.(Figura 1).A device is proposed for wiping motor vehicle glass. The wiping device comprises a wiper arm which, pendularly and in several parts in the longitudinal direction, carries a wiper blade at its free end and its pendulum movement by means of an alternate translation transmission obtained from the alternative translation movement, superimposed on the pendulum movement, of the part of the external wiper arm carrying the wiper blade, and the alternative translation transmission has a toothed segment integral with the frame, which is arranged concentrically with respect to the pendulum axis and with its toothing meshes the teeth of a pinion, with which one end of one translation rod is coupled eccentrically to the other the end of which is articulated to the external part of the wiper arm. To achieve a silent and play-free alternative translation transmission, one of the two teeth has at least two rows of teeth mutually placed side by side, one of which is made of a relatively non-deformable material and the other is arranged elastically deflectable, and the toothing of the other row of teeth looking in the direction of the pendulum axis, at least in a plane that intersects it is larger by reason of the maximum allowed play between the two teeth, compared to the teeth of the rows of teeth (Figure 1).
