Abstract

Transmission de propulsion. Elle a des roues planétaires portées sur l'arbre par des moyens de pivotement alignés diamétralement, définissant un axe de pivotement fixe coupant l'axe de l'arbre d'entrée, normalement à celui-ci, en un point intermédiaire aux roues planétaires, et des moyens d'égalisation, munis d'éléments de liaison, l'un des éléments de liaison en saillie radiale étant relié avec retenue axiale à l'une des roues planétaires seulement, et l'autre élément étant relié avec retenue axiale à l'autre roue planétaire seulement, de sorte que les moyens de pivotement constituent une référence fixe constante. Applicable notamment aux tracteurs de jardinage.Propulsion transmission. It has planetary wheels carried on the shaft by pivoting means aligned diametrically, defining a fixed pivot axis intersecting the axis of the input shaft, normally to the latter, at a point intermediate to the planetary wheels, and equalization means, provided with connecting elements, one of the radially projecting connecting elements being connected axially to one of the planetary wheels only, and the other element being connected axially to the other planetary wheel only, so that the pivot means constitute a constant fixed reference. Applicable in particular to garden tractors.
