摘要: A variable-speed drive system comprising at least one device movable along a guide path, wherein a rotating drive member is provided which is rotated at a constant speed and rolls on a bearing surface associated with said guide path. Means are provided to vary the rolling radius of the rotating member on the bearing surface in dependence upon the position of the moving device along the guide path so that the linear speed of said device may vary according to a predetermined law. The rotating member may be a pulley having a slidable flange and associated with a constant width bearing surface or a one-piece pulley associated with a variable section bearing surface.

摘要: Track is layed on a concrete road bed by keying slabs to the concrete. Bearing members are positioned and anchored on the slabs. Antivibration material may be placed between the slabs and the concrete. A rolling guide system is mounted on the bearing members. Rubber wedges may be interposed between the rolling guide system and the bearing members.

摘要: A transporter having a variable speed includes variable speed providing units consisting of displacement members moving along a guide path. Control members follow a cam. Non-elastic linkages connect the displacement members and the control members of the same unit. The various units are connected by assembly elements.

摘要: The system comprises a generator adapted to substitute a braking order for the orders given by a control device, when the vehicle travels through the sequences of its path at a prohibitive speed. According to the invention, the device comprises trigger means preferably comprising a capacitor 3 enabling it to supply a braking order only after the vehicle has travelled a predetermined distance.
