Abstract

L'invention concerne un système d'entraînement (1) pour un trottoir roulant (3), ledit système présentant un mécanisme d'entraînement (5), un mécanisme de guidage (7) ainsi qu'un premier et un second moyen de traction sans fin (9, 11). Le mécanisme d'entraînement (5) est configuré de manière à entraîner en rotation les deux moyens de traction sans fin (9, 11) en sens opposé l'un par rapport à l'autre. Les deux moyens de traction sans fin (9, 11) sont configurés et sont guidés dans le mouvement de rotation par le mécanisme de guidage (7), de sorte que d'une part des zones du premier moyen de traction sans fin (9) déplacées dans une direction d'avancement (25) coopèrent avec une première face (31) de palettes (29) du trottoir roulant (3) en pouvant être sollicitées en traction dans la direction d'avancement et de sorte que des zones du premier moyen de traction sans fin (9) déplacées dans une direction de marche arrière (27) coopèrent avec une seconde face (33) de palettes (29) du trottoir roulant (3) située à l'opposé de la première face (31), en pouvant être sollicitées en traction dans la direction de marche arrière (27), et de sorte que d'autre part, des zones du second moyen de traction sans fin (11) déplacées dans la direction d'avancement (25) coopèrent avec la seconde face (33) de palettes (29) du trottoir roulant (3), en pouvant être sollicitées en traction dans la direction d'avancement (25), et de sorte que des zones du second moyen de traction sans fin (11) déplacées dans la direction de marche arrière (27) coopèrent avec la première face (31) de palettes (29) du trottoir roulant (3) en pouvant être sollicitées en traction dans la direction de marche arrière (27).
