Description

Transformable truck for driving schools.

Object of the invention

The present invention relates to a truck transformable for driving schools, whose purpose is to be able to perform practices for different types of permits.

Background of the invention

Currently driving schools must have of different types of trucks to be able to carry out the practices for different types of driving licenses. This is because that fixed-box trucks (permits C and C1) have a higher wheelbase than tractor units for semi-trailers (C + E permits), and to the greater or lesser length of the boxes in the first case (shorter length for C1 permits, and longer length for permissions C).

To try to remedy this problem, they know some driving trucks that have a fixed box open and extensible by hydraulic means, which allows carry out the practices of permits C and C1 with the same truck, just extending the box. However this type of trucks on the one hand they do not serve to practice with semi-trailers, and on the other side do not incorporate complete enclosures or closed box so that the practices carried out, with the box open, are not satisfactory for their lack of realism and for not approaching student to the real situation where you will frequently be presented with circumstance of driving closed box trucks.

Similarly, driving trucks count with a reduced number of seats, which forces the truck to go and come to pick up the different students participating in the practices.

These inconveniences are corrected with the use of the truck of the invention.

Description of the invention

The truck of the invention has a constitution  convertible that allows to carry out the practices that the C permits, C1 C + E, which also allows to transport a greater number of students or practitioners, reducing the number of trips and kilometers.

According to the invention, the truck is of the type that adapts its box dimensions to carry out practices of permits C and C1, but also incorporates, among others, the novelty of implementing a fifth wheel hitch for semi-trailers, as well as a hitch for a rear trailer, which also allows permit practices
C + E.

For this, the truck of the invention comprises a tractor unit with fifth wheel hitch for semi-trailers, whose wheelbase has been increased; So as the position of the fifth wheel has also changed. Be thus, on the one hand, achieve a wheelbase similar to that of a fixed-box truck, and on the other hand that can hook the semitrailer, also implementing preferably a transmission boost.

The extensible fixed box structure (for permits C and C1) a rear crossbar materializes extendable and two folding side uprights with guides conductors and supporters of a bridge structure sliders that mount a box closing canvas, bridges that, by allowing its sliding, therefore allow the closure of canvas to adapt to the length given to the box according to the practices are for permission C or C1.

Brief description of the drawings

Figures 1, 2, 3 and 4 show different views of the different configurations that the truck can adopt transformable of the invention.

Figures 5 and 6 show different views of the invention truck in box configuration, with the closure of canvas open and with the rear crossbar respectively retracted and retracted In Figure 5, in addition, the uprights on the side appear dejected right.

Figure 7 shows a detail of the uprights of the bridges, according to the invention.

Description of a practical embodiment of the invention

The truck 1 of the invention is constituted by a tractor unit 2 with fifth wheel hitch 3 for semitrailer trailer 4, as well as a hitch 5 for towing a trailer 6, allowing both circumstances to effect C + E permit practices. The wheelbase is increased with respect to a conventional semi-trailer tractor head, as well as also corrected the position of the fifth hitch wheel.

In the hitch zone 3, the truck rides a convertible structure consisting of two lateral stringers 7 in the ones that a crossbar 8 rear end is plugged in extensively that carries lighting 9 (pilots, turn signals, etc.) of the truck, connecting this lighting to the electrical system of the truck through a wiring 9a extendable helical. In this structure is mounted a canvas closure 10 supported by bridges 11 comfortable, and that allows to configure a closed box 12 in the truck, of adjustable size, which allows to carry out the practices of permits C (crossbar and closing extended backwards) and C1 (crossbar and closing retracted), which logically in this case does not The semi-trailer will be attached, although a 6a trailer to its rear hitch for C + E permit practice as seen in figure 4.

The closure 10 is mounted on the structure thanks to the mounting on the stringers 7 of some lateral uprights 13 folding for bridges 11. the uprights of each upright lateral incorporating parallel longitudinal guides 14a, 14b vertically where a pinion 15 and a respectively run slider or sheave 16 of the lower end zone 11a of the bridges, zone 11a that adopts convex concave shape to improve the Bridge support in an upright position. The upper guide 14a incorporates a rack, not shown, for the pinion corresponding, having provided a crank drive, not shown, to adjust the display of the bridges to along the guides, and therefore the deployment of the canvas closure. Some struts are also provided on the rear crossbar 8 16 detachable to tie the canvas closure.

The uprights 13 are configured based on several sections 13a, 13b, 13c and 13d, some of which 13c are removable to fit the greater or lesser length that is from to the box, when extending the rear crossbar 8, as seen in the Figure 6. In addition, the previous sections of both sides 13a are fixed, that is, do not fall down, so that they are collected the canvas closure 10 and all its bridges, as seen in the Figures 3 and 5 when the truck with semi-trailer is being used. He The rest of the uprights are hinged to allow the semi-trailer assembly (down position) or the closing of canvas (unattended position).

The truck of the invention also incorporates a modification to increase the number of passengers (students in practices plus the instructor), consisting of a second row of seats 20 in the rear, in the part corresponding to the bunk from the cab of the truck, which has been removed, also incorporating in this area a window 21.

Finally, the truck of the invention also you can implement an aerodynamic deflector 22 on your cabin.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
