Abstract

monobloc chassis for towed transhipment vehicle of agricultural use consisting of a longitudinal central body (1) in the form of an elongated closed box, rectangular in section, its horizontal base being larger than its vertical height, which box is terminated at its ends by two transverse elements (3) also in elongated closed box shape, with height equal to that of the central body, and further having a third transverse element (2), also in elongated closed box shape, with rectangular profile equal to the height of the central body (1), inserted in the middle zone of the central body and containing inside the gauge adjustment system and undercarriage, completing the welded monoblock assembly.

1/3 “MONOBLOCK CHASSIS FOR TOWED TRANSFER VEHICLE FROM

AGRICULTURAL USE ”

The present application for an Invention Patent refers to a new chassis concept for use in transshipment vehicles for agricultural use (hereinafter referred to simply as VT), bringing to the technique a series of improvements in relation to its current state , as described below.

The field of application of the present monoblock chassis is that of agriculture.

Current state of the art

Figures 5 and 6 illustrate a typical VT of the current technique, with fig. 6 is a perspective view in the discharge position, and fig. 5 is a perspective view of the conventional chassis (7), which consists of four closed box-shaped beams, two lateral and two transverse, forming a rectangle with a series of transverse and longitudinal reinforcements (8) within that rectangle, being the main transverse axis (2), which supports the semi-axles (9) of the suspension and running systems (usually of the “tandem” type), fixed under the rectangular chassis (7), as can be seen clearly in figures 5 and 6 .

This chassis (7) provides support and fixation for all the other components of the VT, namely: basket (10) carrying the load to be transported / overflowed, columns (12) and lifting mechanisms (11) and basket overflows, header ( 14), tail (15) for towing and brake system (17).

Description of the drawings of the monoblock chassis covered by this patent application:

Fig. 1 - vertical sectional view along the central (1) longitudinal axis of the monoblock;

Fig. 2 - perspective view of the new monoblock chassis;

Description of the new concept of monoblock chassis:

The fundamental differences of this new concept are three, namely:

a) the two longitudinal side beams of the conventional chassis (7) are replaced by a central beam (1), in the form of a wider and more robust closed box, with a base greater than the height, this beam (1) formed by 2 elements or blocks (1) of the same shape, aligned along the longitudinal horizontal axis of symmetry of the VT, elements joined by the insertion of a third transverse block (2) (at 90 ° from the longitudinal axis mentioned above) also in the shape of an elongated box of rectangular profile with the same height of the two blocks, forming a welded monobloc set aligned in a horizontal plane;

b) this monoblock set, in turn, is joined at its ends to two transverse beams (3) in an elongated closed box, both identical and with a rectangular profile with height equal to the height of the beam section (1) and (2), completing the monoblock chassis; the transverse beam (2) containing two semi-axes (4) within two cylinders fixed to the internal walls of the beam (2), semi-axes (4) which project symmetrically out of the beam ends (2), integrating and supporting the VT's running and suspension systems;

c) The transverse element (2) inserted in the median zone of the central box beam (1) contains in its interior a mechanism for adjusting the gauge of the rotating system (usually in the form of “tandem” (5), as shown here), by means of the sliding of the semi-axes (4) that support the “tandem” (5) along the cylinders (6) fixed inside the box beam (2).

Advantages of the new monoblock chassis

There are countless advantages, we will list the most evident, namely:

a) Weight reduction of the complete chassis by about 25%;

b) 40% reduction in welding labor;

c) Reduction in the number of parts, by almost 50%, by eliminating additional reinforcements and beams, facilitating assembly and reducing labor;

d) Greater useful height of the basket (10), due to the lowering of the chassis, even maintaining the same free height on the ground;

e) Lower center of gravity, more stability;

f) Ease and greater amplitude in the adjustments of the VT gauge.

3/3

These advantages can be seen by comparing figures 1 to 4 with figures 5 and 6, which currently have the most representative VT on the market.

In addition to that described above, and according to figures 1 to 6 5 attached, the following components are listed, for better identification of all elements referenced in the drawings, including those inherent to the state of the art and those considered new:

(1) Monoblock central box beam:

(2) Cross box beam inserted in the beam (1);

io (3) Transverse beams at the ends of the beam (1);

(4) Semi-axle support for “tandem” wheels, · (5) “Tandem” wheel,, (6) Cylinder inside the beam (2) containing a semi-axle (4);

(7) Conventional rectangular chassis;

(8) Chassis reinforcements (7);

(9) Transverse beam supporting the “tandem” wheels on the conventional chassis (7);

(10) Basket;

(11) Basket lifting and turning mechanism (10);

(12) Columns and support of the mechanisms (11);

(13) Useful volume gained in the basket (10) with monoblock chassis;
