Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
225 words
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.
Claim 2
Dependent Claim

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.
Claim 3
Dependent Claim
21 words
The vehicle of claim 1, wherein said electric driving means is operable with a lower power than said thermal driving means.
Claim 4
Dependent Claim
41 words
The vehicle of claim 1, wherein said electric driving means alone imparts to said vehicle a traveling speed of 10 to 50 km/hour, and said thermal driving means alone imparts to said vehicle a traveling speed of 60 to 120 km/hour.
Claim 5
Dependent Claim
36 words
The vehicle of claim 1, wherein available DC electric power of said electric power source is about 15 to 50 kW, and available thermal power of said thermal driving means is about 74 to 224 kW.
Claim 6
Dependent Claim
22 words
The vehicle of claim 4, wherein said available DC electric power of said electric power source is about 20 to 40 kW.
Claim 7
Dependent Claim
25 words
The vehicle of claim 1, wherein said electric driving means is operable at 1/10 to 1/2 of available thermal power of said thermal driving means.
Claim 8
Dependent Claim
25 words
The vehicle of claim 1, wherein said electric driving means is operable at 1/6 to 1/3 of available thermal power of said thermal driving means.
Claim 9
Dependent Claim
29 words
The vehicle of claim 1, further comprising an accelerator pedal in said tractor which controls both speed of said thermal driving means and speed of said electric driving means.
Claim 10
Dependent Claim
26 words
The vehicle of claim 8, wherein said accelerator pedal control speed of said electric driving means through an electronic device of the thyristor current chopping type.
Claim 11
Dependent Claim
36 words
The vehicle of claim 8, further comprising a gear box for said thermal driving means, and locking means for permitting operation of said electric driving means only when said gear box is in a neutral position.
Claim 12
Dependent Claim
20 words
The vehicle of claim 1, further comprising means driven by said thermal driving means for recharging said electric power source.
