Description

Semi-trailer vehicle with semi-axle lines for transport of heavy machinery.

The present invention relates to a vehicle semi-trailer with a rolling platform, which presents a structural configuration with particular characteristics. From so that you can make the most of the volume available for the load, both on the platform that supports the load, and on a new space that is created between the chassis of the rolling area rear Using the provision of two chassis of independent rolling on the side, resulting in a space between them, Useful to accommodate cargo.

Background of the invention

There are a number of inventions on the market characterized in that they integrate in the rear rolling area a or several lines of semi-axes arranged each of them distributed between the two sides of a central chassis, which occupies a space not Usable to accommodate cargo. These chassis are attached each other in different ways depending on the manufacturer in question, leaving therefore a load volume on the platform of more or less wide rolling depending on how this has been resolved structural union, usually with a structural arrangement through tube-shaped profiles.

We can cite as background of the invention EP1577159B1 in which reference is made to a semi-trailer consisting of a series of commercial elements and with a series of particularities, such as the surface of cargo and the rear taxi area are the same central chassis of continuous section in the form of beam beam. This central chassis-drawer, supports semi-axle lines lateral by means of brackets that hang to the sides. Presenting, finally, a double figure formed by a U on a tube rectangular that limits in its height the useful space for the load.

The proposed semi-trailer vehicle It presents a fundamental variation, and it is made up of two chassis independent, which carry the semi-axle lines and which does not present no structural element between the two, so it is achieved, that the volume between the two chassis is used to accommodate elements and / or parts of the loads (5). With this distribution in construction from both chassis space is gained for the placement of the elements of load (5) between the rolling, so that the total height of the load to be transported compared to others systems.

This rolling element (3) can be built in a completely modular way integrating the number of axles (13) necessary depending on the load needs to transport.

The loading platform (2) can also be adapt with minor modifications to the joint with the tread to thus enable the transport of bulky heavy elements or great length

Description of the invention

The proposed semi-trailer vehicle is characterized by integrating 3 elements for the composition of the semitrailer assembly:

The hitch part of the loading platform it will be made with a detachable neck or dolly neck type element (1) according to utility model U200800869, characterized by having one or more axes or semi-axle lines (14) pivoting integrated in the detachable collar itself that allows to increase in weight, the load useful of a semi-trailer vehicle without exceeding the maximum load transmitted to the tractor and without the need for elements independent.

A loading platform (2) that is characterized because it is adaptable depending on the elements to be transported and allows different interchangeable configurations, modifying only and exclusively the element of reception of the load surface to the detachable neck or dolly neck (1); and the connecting element of the loading platform to the elements of rolling

A rear tread (3) that will integrate the number of semi-axes (13) required depending on the load to transport. These axles (13) are characterized by being addressable, with the feature of being synchronized between they and governed by the direction of the truck, by means of a automatic steering device (15).

This part of the race is characterized by have a hollow area (8) between both chassis (10) and (11). This design of the rolling structure takes full advantage of the space located between both chassis (10) and (11) thus being able to reduce the transport height (5) with the advantages that this entails, at the same time which allows transporting heavier elements since it optimizes the distribution of the load on the loading platform (2).

Description of a preferred embodiment

The particularity of the semi-trailer vehicle proposed is in the constructive form of the rolling platform (3) which has the following characteristics:

The structure that makes the function resistant and which allows anchoring to the loading surface is made of such that each of the two chassis (10) and (11) that support the semi-axle lines (14) are arranged leaving a space completely free (8) between both right (11) and left chassis (10)

Between each of the two chassis (10) and (11) no the placement of structural elements is necessary, allowing thus the use of all the available volume between both chassis to increase the payload volume and be able to reduce the maximum height of the load of the machinery to be transported since between chassis is usually arranged, for example, the arm with the shovel of the excavator machine (4) to be transported, and the closer it is of the ground, less useful height will have the total volume of the element a transport (5).

Another aspect of this constructive form is the to have an automatic steering device (15) synchronized between the axles (13) that contain the two chassis independent. Helping both chassis remain parallel, and allowing the correct circulation of the semi-trailer.

If you want to strengthen the hollow area (8) between both chassis (10) and (11) the braces (12) can be placed necessary at the bottom of it, thus increasing the rigidity of the set and enabling the provision of some platform so that the load can rest on it if it were necessary for operational reasons.

The versatility of this element is therefore total, and expands the possibilities of using existing systems, ensures adaptability and allows scaling based on the machinery or cargo to transport. The element or loading platform (2) can present different configurations depending on the length or volume of the load, even allowing to incorporate Extendable platforms using telescopic beams (6) and (7).
