A windshield wiper drive train adapted for long life is disclosed. The drive train includes motor assembly that supports and drives a drive shaft. A circular drive plate is attached eccentrically to the drive shaft to rotate through an eccentric orbit about the drive shaft as the drive shaft rotates. A connecting member having a body portion defining a round opening that is slidingly fitted about said circular drive plate and an arm portion extending outwardly from the body portion undergoes reciprocating motion in response to rotation of said circular drive plate. A rocker assembly having a rockshaft and a rocker arm attached to the rock-shaft is connected by pivot joint to the arm portion of the connecting member. In operation, the rocker assembly is rocked by the reciprocating motion of the arm portion when the drive shaft rotates. The rockshaft is adapted to engage a further attachment such as a windshield wiper.
Cette invention concerne un mécanisme d'entraînement d'essuie-glace à longue durée de vie utile. Il comprend un moteur conçu pour supporter et en même temps faire tourner un arbre d'entraînement portant un plateau circulaire excentrique adapté pour décrire une orbite excentrique autour de celui-ci. Une bielle dont le corps comporte une ouverture ronde est disposée en ajustement coulissant autour dudit plateau circulaire de façon que sa tige s'anime d'un mouvement de va-et-vient lorsque le plateau circulaire tourne. Un ensemble basculeur formé d'un arbre basculeur et d'un culbuteur fixé à celui-ci est raccordé à pivot à la tige de la bielle. Lorsque le moteur tourne, l'ensemble basculeur s'anime d'un mouvement de balancier sous l'impulsion de la tige de bielle animée d'un mouvement de va-et-vient. L'arbre basculeur est adapté pour recevoir le bras porte-lame essuie-glace.
