First Claim
Patent Images
1. A composite road vehicle comprising:
- a tractor provided with first driving wheels and thermal driving means for providing power to the first driving wheels for propelling the composite road vehicle at a first traveling speed; and
a collection and distribution trailer or semitrailer removably connected to said tractor, the trailer or semitrailer comprising a support structure;
second driving wheels attached to said support structure;
an electric power source of the battery type;
electric driving means controlled from the cabin of the tractor for providing sufficient power to the second driving wheels for propelling the composite road vehicle, with the trailer or semitrailer connected to the tractor, at a second traveling speed lower than said first traveling speed;
a transmission coupling said electric driving means to said second driving wheels; and
a hauling compartment, attached to said support structure, with substantial available space over and above that occupied by the electric power source, electric driving means and transmission for collection and distribution of materials;
whereby, when the thermal driving means is disengaged and the electric driving means is engaged, the trailer or semitrailer propels the composite road vehicle at the second traveling speed for collection and distribution of materials, whereas when the electric driving means is disengaged and the thermal driving means is engaged, the tractor propels the composite road vehicle at the first traveling speed.

Abstract
A transport method is disclosed wherein relatively slow displacements with frequent stops and relatively rapid displacements with few stops may be efficiently performed with the same vehicle or the same vehicle unit. The slow displacements are made by means of one or more electric batteries and the rapid displacements are made by means of one or more thermal engines.
