Abstract (en)
[origin: WO2010052075A1] The invention relates to a traction mechanism (1), a tractive drive comprising said traction mechanism, and a lift comprising said tractive drive. The traction mechanism is characterised in that the traction carrier (2) is coated with an elastomer material to form coated traction carriers (3). The coated traction carriers (3) are arranged next to each other in a plane in the cross-section of the traction mechanism, at such a distance from each other that there is a space (6) between two coated traction carriers (3). The coated traction carriers (3) are connected at the back by a rear layer, the space (6) beginning on the side facing away from the rear layer (4) extends up to the central point (5) of the traction carrier, and the ratio of the second diameter (d2) of the coated traction carrier (3) in relation to the first diameter (d1) of the traction carrier (2) is between 1.05 and 2.25. The tractive drive is characterised in that the traction mechanism can be driven by at least one traction disk, and each coated traction carrier (3) engages in a corresponding groove (10) of the traction disk (9). The rear layer (4) is arranged on the side of the coated traction carriers (3), that faces away from the side engaging in the grooves (10) of the traction disk (9), and at least one traction carrier (2) engages in the corresponding groove (10) of the traction disk (9) by between 5 % and 25 % of its diameter (d1).
