Description

Detailed Description The present invention relates to the development of a modular cabin structure that can be used in a Medium Truck or Tractor Truck. A medium truck is one that, due to its construction, design and use, does not tow any type of trailer and the load it carries is not more than 15 tons. In terms of the regulations of the Ministry of Communications and Transportation and in accordance with international standards, a Medium Truck is a motor vehicle with chassis for the transport of effects or less than 10 people, with a gross vehicle weight of between 6,351 and 14.968 Kilograms. On the contrary, a tractor, is one that by its construction, design and use, drags trailers of all kinds and is designed to carry large weights. In terms of the regulations of the Ministry of Communications and Transportation, and in accordance with international standards, a Tractor Truck is a two- or three-axle automotive vehicle intended for the transport of effects, either by towing trailers, semi-trailers , or with integrated equipment, with a gross vehicle weight of 14,969 kilograms and above. The cabin object of the present invention, is called modular type, because it is formed with sub-assembled pieces that will be common between the medium truck and tractor and that in turn, form the two side panels or sides that will make up the counter frames of the right and left doors, respectively; the rear panel of the cabin, the awning and the floor and the front or parafuego of the same. The object of this invention is to provide a cabin structure that can be used interchangeably both in medium trucks, as in tractors, and that can be built indistinctly in the same assembly line for one or the other model, which contains: two sections lateral, which will form the counterframes of the left and right doors respectively, with two reinforcements for each counterframe on the front and rear; a rear panel of the cabin, characterized in that it is formed by four corners, one upper and one lower, two right and two left; two pillars called "B" reinforcement for the rear panel, one left and one right; a rear platform and two reinforcements for the "B" pillars of the rear panel; Description an awning characterized in that it is formed by a base for zeppelins or navigation lights; two awning sides, one left and one right; a crosspiece or transverse; a rear crossbar; two longitudinal straps, one left and one right; and two pillars, one left and one right; a floor extending from the rear platform of the rear panel, characterized in that it extends to the transmission cover and from that point is bent upwards with the inclination required to join with the front panel called parafuego; a front panel characterized in that it is formed by a cover mask for windshield wipers and two pieces of reinforcement for the mask; Traditionally, in the specifications of the designs of the cabins for medium trucks, specific designs and dimensions are used for this type of trucks, and therefore, although at first glance they may have the same shape, the dimensions of their components vary, consequently, they are produced in different assembly lines. In the traditional construction of cabins for medium trucks and tractor cabins, it is not possible to use the same assembly line at the same time, because the tools used in the assembly of both cabins are also different; in such a way that the assembly line has to be stopped to effect the change of tooling or to have two different production lines, translating into loss of time, higher production costs, investments and manpower. The different pieces that compose the structure of the cabin are manufactured preferably with sheet of steel of high resistance, which are molded with dies; The parts that make up the structure of the cabin contain slots where they fit together and are fixed with resistance welding points.
