Wherein the pulley has a diameter greater than 100 mm, it is made of a single part, having helical cogs, whereas the machine has an associated deflecting pulley (23), non-slip rollers, and the cogged belt is made of transparent polyurethane and a textile mesh covering the cogged portion. In addition to a uniform and well balanced translation of the car, an effective reduction of noise levels is achieved.
