Français : SCHÉMA DE LA TRANSMISSION ORIGINALE PANHARD DANS LAQUELLE TOUTES LES VITESSES SONT INDIRECTES. CELA EST GÉNÉRALEMENT CONNU EN TANT QUE TYPE DIRECT OU PROGRESSIF DE TRANSMISSION: "La première innovation réussie dans une transmission visant spécifiquement à résoudre certains des problèmes du moteur à essence peu souple a été la transmission à train baladeur inventée par Levassor, ingénieur pour la firme Panhard et Levassor, de France (Figure 1). Il est devenu presque universel aux États-Unis dans les années 1920 pour les voitures, les camions et les autobus. Il se composait de deux arbres parallèles montés sur roulements. L'arbre primaire, relié à l'embrayage, était carré et portait trois vitesses. Trois autres engrenages étaient montés sur l'arbre secondaire. Le conducteur pouvait déplacer la position de l'arbre primaire pour amener les pignons correspondants en prise."
English: DIAGRAM OF ORIGINAL PANHARD TRANSMISSION IN WHICH ALL SPEEDS WERE INDIRECT. THIS IS GENERALLY KNOWN AS THE STRAIGHT-THROUGH, OR THE PROGRESSIVE TYPE OF GEAR: "The first successful innovation in a transmission specifically aimed at solving some of the problems of the inflexible gasoline engine was the sliding gear transmission invented by Levassor, engineer for the firm Panhard and Levassor, of France (Figure 1). It came into nearly universal use in the United States by the 1920's for cars, trucks and buses. It consisted of two parallel shafts mounted on bearings. The primary shaft, connected to the clutch, was squared and carried three gears. Three other gears were mounted on the secondary shaft. The driver could shift the position of the primary shaft to bring the corresponding gears into mesh." |
