ABSTRACT:

TECHNICAL FIELD RELATED TO THE INVENTION
The present invention is related to the assembly of parts for medium, heavy, and tractor trucks, and most particularly with the space frame of the convential truck cabin; the cabin forms the interior space which the truck operators occupy while driving the vehicle.
BACKGROUND
The space frame of the cabin for medium, heavy, and tractor truck subject matters of the present invention is designated as a modular type, since it is formed by sub-assembled pieces which, in the present case, are the same for medium, heavy, and tractor trucks. The cabin for medium, heavy, and tractor truck subject matters of the present invention may be assembled without distinction in the same assembly line for units class
6
,
7
, and
8
, (the class corresponds to the SAE—Society of Automotive Engineering classification, which includes the vehicles mentioned herein), without the need to stop the assembly line and using the same tool set in both cases.
As a person skilled in the art already knows, medium and heavy trucks are those which, due to their construction, design and utilization are not used for hauling trailers, and the load they transport does not exceed 19 tons. Pursuant to the regulations of Mexico's Ministry of Communications and Transports and according to international standards, a medium truck is an automotive vehicle with a chassis built to transport goods, with a vehicular gross weight that ranges between 6,351 and 14,968 kilograms.
In contrast, a tractor truck is one which, due to its construction, design and use, is adequate to haul all kinds of trailers, and is designed to transport large weights for great distances along the highways. Pursuant to the regulations of Mexico's Ministry of Communications and Transports and according to international standards, a tractor truck is an automotive vehicle with two or three axles used to transport goods, be it by means of hauling trailers, semi-trailers or with an integrated equipment, with a vehicular gross weight of 14,969 kilograms or more.
Until now, the space frames of cabins for medium, heavy, and tractor trucks have been distinct and constructed separately, in different assembly lines, and using particular tools for each type of vehicle or in the same assembly line. This has meant that the production of the cabin for one kind of vehicle has had to be stopped in order to construct the cabin for another type of truck. Since the cabins do, however, have pieces in common, the system of constructing them in different assembly lines has generated down-time, as the construction of the cabin for one kind of vehicle is suspended to construct the cabin for another type of vehicle. Apart from using specific tools for each kind of vehicle and, of course, the personnel to construct and assemble the cabin required by each kind of vehicle. In sum, this means greater production expenses, more time used and fewer units produced, thus increasing the cost of cabin units. This is even more serious when there is only one assembly line and it is necessary to stop the manufacturing process of one cabin to construct the other.
Purposes
1. To provide the space frame of a cabin for medium, heavy, and tractor trucks.
2. To provide the space frame of a single cabin that can be used for medium, heavy, and tractor trucks.
3. To provide the space frame of a single cabin for medium, heavy, and tractor trucks that can be constructed in the same assembly line of each type of vehicle.
4. To provide the space frame of a single cabin for medium, heavy, and tractor trucks that can be manufactured with the same type of tools.
5. That the production of one type of cabin for one kind of vehicle does not stop in order to manufacture the cabin for another kind of vehicle.
6. To reduce expenses in time, money, personnel, and tools in the manufacture of the cabins required for medium, heavy, and tractor trucks.
