Definitions
- the present invention is found in the technical sector of urban cargo vehicles, specifically in the case of high-volume and light-weight cargo vehicles. STATE OF THE ART
- the problem increases when finished products or raw materials with a high cubic coefficient are distributed, including the long formats that protrude from typical platforms when transiting urban spaces, where vehicular traffic is intense and regulated according to the dimensions and weights of the transport units that are of conventional use.
- the usual technique is to use trucks with semi-trailers of 13 or more meters long for long-format raw materials; trucks, mini trucks, light trucks or rigid or load-bearing chassis vans facilitate the transport and distribution of high cubic-coefficient merchandise that do not contain long formats.
- the vehicles described have different powers in their engines (with ranges that vary between 40 and 400 kW) have gearboxes and clutches manufactured to transport weights in a range that varies from 130 kilos to 1 ton per cubic meter of capacity total load on its semi-platforms, trailers or vans; said characteristics exceed the requirements of the solution purpose of the present invention because these vehicles use the full volume of their cubic capacity and use small portions of their payload as well as the power of their engines.
- the transported load of greater weight is the vehicles themselves and not the cargo of merchandise.
- These vehicles are often overdimensioned in power and load, but undersized in cubic capacity for the transport of finished products and light weight and large volume raw materials also known as "high cubic coefficient".
- U.S. Patent Publication Number US2804314A discloses a control for a fifth wheel with means for limiting rotation which comprises a pair of rotating gears, each mounted on a rotating vertical axis, with brake shoes, drum and a hydraulic expansion piston, with manual lever braking;
- this system of limitation of rotation with double gear and shoe is designed for large volume and heavy loads, so it is not practical to use in large volume loads and light weight in urban environments, adding unnecessary components that only They take up space and increase the weight of the vehicle.
- the prior art cargo vehicles have the following problems: Limitations and / or prohibitions of circulation for tractors with semi-trailers, balanced trailers or trailers with steering axles typically conventional of great length in urban spaces and zones densely populated High fuel consumption for towing high volume and low weight loads or high cubic coefficient.
- Tract trucks with semi-trailers, trucks, mini trucks, light trucks or vans of the common type have non optimal characteristics for the efficient transport of high cubic weight merchandise. Tract trucks without any semi-platform or coupled trailer, trucks, mini trucks, light trucks and vans with transport capacities of 13 m3 or more, can not be used as personal vehicles in urban spaces due to the length, width or height they occupy to park.
- the present invention was developed consisting of a vehicle subdivided into two: a mini tractor and a light semi-platform. These are coupled by a fifth wheel with a king pin, allowing the transport of high cubic coefficient products including long formats; the resulting vehicle with interchangeable semi-platforms adapts to the different general regulations of transit as to the particular or specific ones of the different destinations and urban areas, making the present invention a vehicle apt to circulate efficiently in various spaces through the rapid exchange of semi-platforms that are coupled, articulated and offer wheel turn or wall to wall smaller than any rigid transport vehicle with equal cubic capacity or total length.
- the mini tractor unit of the invention is shorter between the steering and traction axles compared to a cargo transport vehicle of the common type.
- the distance between the steering (front) and traction (rear) axles of the mini tractor is 1.3 to 1.7 times the width of the steering axle. With these proportions the distances or measurements between the front steering axle and the traction rear axle are determined; the transmission shaft included between the output of the gearbox and the transmission crown where the traction axles are located is less long between 40% and 60% with respect to the vehicle transmission axis of the common type, which facilitates the reduction of the total length of the original chassis including the elimination of the rear overhang achieving a lower total length in a range that varies from 15% to 25%. With these modifications the mini tractor unit weighs less than the original vehicle in a range that varies from 10% to 20%; the weight reduction in the mini tractor unit transfers more payload capacity for any light semi-platform that fits.
- the mini tractor unit of the invention provides wheel and / or wall to wall turns shorter than a truck, mini truck, light truck or any other transport vehicle with equal or less total length than the mini tractor head coupled to a light semi-platform; due to the joint that occurs between the mini tractor and semi-platform coupled by the fifth wheel and king pin.
- the semi-platform be a low bed, in such a way that it is closer to the ground, facilitating access to the merchandise, as well as increasing the volume of cargo. This is due to the fact that in order to drive in urban areas it is not necessary for the cargo vehicle to have a high platform. At the same time, the volumetric capacities that generate useful spaces not typically used are optimized.
- the mini tractor unit of the invention is wider in the rear than a mini truck or light truck in a range of 16% to 23% when the traction axle of the vehicle originates! It has simple wheels and is replaced by dual wheels or double wheels. These provide greater stability due to a new lower center of gravity that allows coupling light semiplataformas wider and with greater volumetric capacity. Dual or double-wheeled wheels provide greater tractive force in conjunction with a shorter transmission shaft. Dual wheels or double wheels also increase the braking capacity by multiplying the area of contact with the road both when moving the mini tractor head alone and when it is coupled to a semi-platform light equipped with brakes on dual wheels or double wheels installed on your shaft (s).
- the vehicle has dual wheels on one or more rear axles, located in the mini tractor unit and / or semi-platform.
- the mini tractor unit of the invention has installed the fifth wheel with a perpendicular separation of between 100 and 500 mm behind! traction shaft modified, this position increased the distribution of useful load to be transported because the main weight becomes shared between the steering axles, the modified traction axle (s) and the axle (s). ) of the light semi-platform.

The mechanism acts to stop tota!
- the system also provides greater safety in forward travel, facilitates turns in curves or narrow streets and carrying out maneuvers of recoil and / or parking in reduced spaces such as urban spaces, allowing the driver to exercise control of direction on the semi-platform coupled efficiently.
- the control mechanism of the horizontal rotation located on the vertical axis where the kingpin typically pivots is simple, practical and strong enough to control the turn with loads of low weight and large volume.
- the system of mechanisms for controlling the horizontal rotation of the light semi-platform includes systems that link, fix and lock vertically the mini tractor unit of the invention with the light semi-platform coupled when they move together eliminating the horizontal pivot natura!
- the system of mechanisms for the control of the horizontal rotation of the semi-platform has the same angular capacity of vertical free rotation (axial play) that the fifth wheel has on e! axis that fastens it to its own base, and that make the fifth wheel a typically conventional system where the kingpin pivots on the horizontal plane, and in a limited way on the vertical plane (axial play), allowing the mini tractor and The semi-platform moves coupled on irregular roads without affecting its normal running.
- the system of mechanisms for horizontal rotation control between the mini tractor unit of the invention and the coupled semi-platform can be obtained with the installation of friction or controlled rotation systems, such as shoe and drum brakes, disc brakes with sufficient capacity (force) to contain the lever or torsion arm that exerts the desired steering angle considering the distance between the axis (s) of the light semi-platform and the optimum rotation point formed by the fifth wheel with the king pin when they are crimped.
- friction or controlled rotation systems such as shoe and drum brakes, disc brakes with sufficient capacity (force) to contain the lever or torsion arm that exerts the desired steering angle considering the distance between the axis (s) of the light semi-platform and the optimum rotation point formed by the fifth wheel with the king pin when they are crimped.

- the total weight in the light semi-platform including the payload is transmitted by means of the king pin to the fifth wheel bearing from 60% to 30%; the variation of the total weight in the described parts is inverse to the quantity of axes installed in the semi-platforms, that with a greater number of axes, less weight is obtained on the kingpin and the fifth wheel.
- the fifth wheel is equipped with weight sensors, the sensors use the load cells installed between the part of the fifth wheel that engages with the kingpin and the base that is fixed to the chassis joined by an axle where the fifth wheel swings vertically; the weight sensors detect the payload when the semi-platform is coupled by the king pin to the fifth wheel of the mini tractor unit of the invention.

- the semi-platform (25) is equipped with a weight sensor (34) on the fifth wheel (10) that uses load cells installed between the fifth wheel (10) and the base (12) of metal that actuate the payload when the semi-platform (25) is coupled with the fifth wheel (10).
- load cells or weight sensors (35) installed on the semi-platform axis (32) are located between the springs (36) of the semi-platform (25) of suspension and the axis (32) of semi-platform (25).
- Load cells designed to support compression, tension and bending loads are installed to detect strain values; digital load cells produce deformations through circuits that detect cascading reactions; obtained the resistances are transmitted by means of a transduction system (37), with these values are determined appropriate loads, overloads and / or average weights.
- the load signals detected in cascade are transmitted from the semi-platform (25) to the tractor (1), through the junction (38) interconnecting with a central electronic device or board (31) that collects the total data of one or several load cells and develops statistical load analysis, the information is visible to the driver on a control board (31), and allows to determine excess weight before starting the transfer or during the journey.
- the driver has the information at all times and can use the assisted traction generated by the vehicle.
- right servomotor (52) and the left servomotor (53) installed on the dual wheels (33) of the axle (32) of the semi-platform (25).
- the preferred model is developed considering semiplataformas (25) with low bed chassis (46), characterized for having lower floor clearance (47) of 300 mm, which increases the load volume and a lower center of gravity is obtained.
- the preferred model consists of a mini tractor (1) and a light semi-platform (25) which, coupled together, have a total length of the invention (43) of 8,200 mm, which has the advantage of being articulated at 2,200 mm from the front of the vehicle.
- the mini tractor head being a suitable vehicle to circulate in urban spaces.
- the aerodynamic and safety advantages are contained to maximize the volume transported, facilitating the use of spaces typically not used between tract trucks with semipla ⁇ aformas, which leave large spaces to avoid contact between both parties during turn maneuvers when articulated; in the case of the preferred model, these spaces are reduced between surfaces that are complemented by concave contact surfaces (48) with convex contact surfaces (49) when the mini tractor unit (1) articulates with the semi-platform (25).
- the preferred measures correspond to a semi-platform (25) with a low bed chassis (46) having an extension of the semi-platform (40) of 6,000 mm, with a half-platform width (41) of 2.010 mm and a height of the semi-platform (42). ) of 3,000 mm measures with which a cargo volume is obtained 5 times greater than the van of the mini truck, light truck, and it is 1, 040 mm less than 2 units of the mini truck, light truck aligned one after the other, considering that between both can only transport 20% of the capacity of the mini tractor unit (1) with the semi-platform (25) of the preferred model, the advantages described are evident.
