The driver of the vehicle. Published 10.01.2008]. For the displacement of the surface of the Torah and the setting in motion of the vehicle applied friction closed infinite element associated with traction drive, made as a sheave speed transmission.
The disadvantage of this technical solution is overly inflated to the location of the center of gravity of the vehicle that is causing it to swing and sliding down the track when placing it on a flat surface in the transverse direction. This fact reduces the efficiency of the device, as it requires constantly alignment of the vehicle on the track, which increases the cost of energy in motion.
