Title
(EN) DRIVE WHEEL FOR TRACK APPARATUS
(FR) ROUE D'ENTRAINEMENT POUR SYSTEME DE CHENILLE
Abstract
(EN) A drive wheel (212) engaged with flexible track (15) of track apparatus (220) mountable on a vehicle axle, the drive wheel including a peripheral portion which, between radially-extending drive members (230), has outwardly-facing lug-engagement surfaces (223s) in position for engagement with the distal surfaces (32a) of the track lugs (32), to extend the useful life of flexible track. Preferred embodiments have spaces facilitating removal of debris. Certain preferred lug-engaging surfaces are provided by peripherally-spaced cross-members (223). The drive wheel is preferably free of side structure, allowing track lugs to adjust precise positions of engagement with lug-engagement surfaces.
(FR) L'invention concerne une roue d'entraînement (212) venant en prise avec une chenille flexible (15) d'un système de chenille (210) pouvant être monté sur un essieu d'un véhicule. Cette roue d'entraînement comprend une partie périphérique qui présente, entre des éléments d'entraînement (230) s'étendant radialement, des surfaces (223s) tournées vers l'extérieur positionnées de façon à venir en prise avec les surfaces distales (32a) des crans (32) de la chenille, la durée de vie de la chenille flexible pouvant ainsi être prolongée. Des modes de réalisation préférés comprennent des espaces facilitant le retrait des débris. Certaines surfaces (223s) préférées sont formées par des éléments transversaux (223) espacés sur la périphérie. De préférence, cette roue d'entraînement ne présente pas de structure latérale de sorte que les crans (32) de la chenille puissent être positionnés avec précision pour venir en prise avec les surfaces (223s) prévues à cet effet.
