Title
(EN) WORKING VEHICLE WITH TRAVELING DEVICE HAVING WHEELS
(FR) VÉHICULE DE TRAVAIL AVEC UN DISPOSITIF DE DÉPLACEMENT AYANT DES ROUES
(JA) 車輪を有する走行装置を備えた作業車両
Abstract
(EN)
A traveling device (11) is provided with: an electric motor (16) provided to the vehicle body (2) of a dump truck (1); an output shaft (17), the axial base end of which is connected to the electric motor (16) and which outputs the rotation of the electric motor (16); a closed-end hole spline section (53) formed at the axial front end of the output shaft (17); and a input shaft (42) which has a shaft spline section (54) joined by splines to the hole spline section (53), and which inputs the rotation of the output shaft (17) to a speed reduction gear mechanism (27). The output shaft (17) is provided with: an oil retention space (55) formed at the innermost part of the hole spline section (53); an annular oil groove (56); and an oil passage (57) for providing communication between the oil retention space (55) and the annular oil groove (56). Lubricating oil (100) supplied to the annular oil groove (56) is supplied to the oil retention space (55) through the oil passage (57) and is supplied to the spline joint between the hole spline section (53) and the shaft spline section (54) by the rotation of the output shaft (17).

L'invention concerne un dispositif de déplacement (11) comportant : un moteur électrique (16) disposé sur la carrosserie de véhicule (2) d'un camion à benne (1) ; un arbre de sortie (17), dont l'extrémité de base axiale est reliée au moteur électrique (16) et qui délivre en sortie la rotation du moteur électrique (16) ; une section de cannelure de trou (53) à extrémité fermée, formée au niveau de l'extrémité avant axiale de l'arbre de sortie (17) ; et un arbre d'entrée (42) qui a une section de cannelure d'arbre (54) jointe par des cannelures à la section de cannelure de trou (53), et qui amène la rotation de l'arbre de sortie (17) à un mécanisme d'engrenage de réduction de vitesse (27). L'arbre de sortie (17) comporte : un espace de rétention d'huile (55) formé au niveau de la partie la plus interne de la section de cannelure de trou (53) ; une rainure d'huile annulaire (56) ; et un passage d'huile (57) pour fournir une communication entre l'espace de rétention d'huile (55) et la rainure d'huile annulaire (56). De l'huile de lubrification (100) alimentée à la rainure d'huile annulaire (56) est alimentée à l'espace de rétention d'huile (55) par l'intermédiaire du passage d'huile (57) et est alimentée au joint à cannelures entre la section de cannelure de trou (53) et la section de cannelure d'arbre (54) par la rotation de l'arbre de sortie (17).
