(EN) GEAR BOX ASSEMBLY
(FR) BOITE DE VITESSES
Abstract
(EN)
A toy vehicle transmission assembly unit having a drive gear that is nonrotatably mounted on a driven axle (12), and a multiple gear train that establishes a driving connection between the drive gear and a driving gear mounted on a shaft outwardly extending from a motor. The gear (65) of the multiple gear train that immediately establishes the driving connection with the drive gear is shifted laterally by a shift lever (44) that disengages the gear train from the drive gear. The transmission assembly unit is enclosed in a housing that provides a rotatable mounting for the drive gear.
(FR)
Unité de transmission pour véhicule d'enfant comprenant un pignon de commande monté de manière non rotative sur un essieu commandé (12) et un train d'engrenages multiples qui établit une liaison cinématique entre le pignon de commande et le pignon d'entraînement sur un arbre se prolongeant hors du moteur. Le pignon (65) du train d'engrenages multiples qui établit immédiatement une liaison cinématique avec le pignon de commande se déplace latéralement au moyen d'un levier de changement de vitesse (44) qui désaccouple le train d'engrenage du pignon de commande. L'unité de transmission se situe dans un logement qui sert de support rotatif au pignon de commande.
