Title (EN) ROUNDED TRACK IDLERS
(FR) GALETS TENDEURS POUR CHENILLES ARRONDIS
Abstract:
(EN) An agricultural vehicle (10) has a chassis (32) with a drivetrain (12) and at least one rubber track assembly (14) with a rubber track belt (16). The rubber track assembly (14) has at least one idler (20), each of which has two idler wheels (40) spaced apart on an axle (42). The idler wheels (40) each have a tapered outer surface (52) that together define a tapered profile (50) that causes the rubber track belt (16) to self-center upon the rubber track assembly (14). The tapered profile (50) may define a pair of straight lines at a shallow angle θ, a portion of a circle, a portion of an ellipse, a parabola, or a hyperbola.
(FR) L'invention concerne un véhicule agricole (10) comprenant un châssis (32) doté d'une transmission (12) et au moins un ensemble chenille en caoutchouc (14) doté d'une courroie de chenille en caoutchouc (16). L'ensemble chenille en caoutchouc (14) comprend au moins un galet tendeur (20), chacun des galets tendeurs comprenant deux roues de galets tendeurs (40) espacées sur un essieu (42). Les roues de galets tendeurs (40) présentent chacune une surface externe conique (52) qui définissent ensemble un profil conique (50) qui amène la courroie de chenille en caoutchouc (16) à s'auto-centrer sur l'ensemble chenille en caoutchouc (14). Le profil conique (50) peut définir une paire de lignes droites au niveau d'un angle faible θ, une partie d'un cercle, une partie d'une ellipse, une parabole ou une hyperbole.
