DESC:NON-TOPPLING, LOAD CARRYING TRAILER
Field of the invention:
The present invention generally relates to a trailer, and more particularly it relates to a non-toppling trailer used for load carrying.
Background of the invention:
The existing design of agricultural trailer is very much prone to accidents due to many reasons. Other than transport of agricultural products, the trailers are used for transport of building materials like brick and sand, transport of farm labor, etc. Agricultural trailers are always subjected to excessive loads to reduce the cost of transportation without paying much attention to safety. With reference to the figures 1 to 3, a load carrying trailer system (100) in accordance with the existing art is shown. In the existing art, the loading container (10) is located fully above the wheels (30). The trailer (100) is having leaf spring suspension system (20). When the trailer (100) is overloaded and is travelling on a tilted road as shown in figure 1, overloading of container (10) causes the centre of gravity to get pushed up and the possibility of toppling goes up. Secondly, overloading usually makes the leaf spring system (20) inactive or break into pieces, making the trailer (100) unstable. The brakes fitted in the presently used design are not adequate (or totally absent) to hold the Trailer (100) on slopes and hence unsafe.
Accordingly, there exists a need to improve the design of load carrying trailer that will accommodate more payload without toppling on slopes and turns.
Objects of the invention:
An object of the present invention is to provide a load carrying trailer with reduced risk of toppling.
Another object of the present invention is to increase the load carrying capacity of a trailer.
Still another object of the present invention is to provide an improved design of load carrying trailer that will reduce serpentine movement and the risk of accident due to accidental breakage of Leaf springs.
Summary of the invention
Accordingly, in one aspect the present invention provides a non toppling, load carrying trailer that provides nearly 50% more storage space therein and avoids serpentine movement of the trailer when it is attached to any prime mover like an agricultural tractor. The non toppling, load carrying trailer of the present system comprises of a rectangular frame having a front end and a rear end to which a pair of front wheels and a pair of rear wheels is fitted. Two wheels in each of the pair are linked with a rubber torsion bar suspension. A container is fitted on the rectangular frame and a draw bar is fitted to front end of the rectangular frame for enabling attachment of the trailer with the prime mover. The container fitted on the rectangular frame is having a base portion designed to occupy the space between the wheels, thereby providing up to 50% more storage space therein, bringing down the centre of gravity, and improving the stability of the trailer, wherein the use of rubber torsion bar suspension enables to accommodate the container and absorbs about 50% shocks thereby enabling the trailer to move with the prime mover without a serpentine movement.
Brief description of the drawings:
The objects and advantages of the present invention will become apparent when the disclosure is read in conjunction with the following figures, wherein
Figures 1 to 3 show schematic views of a load carrying trailer system in accordance with the existing art.
Figures 4 to 8 show schematic views of a non toppling load carrying trailer system in accordance with the present invention.
Detailed description of the embodiments:
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
The present invention provides a non toppling trailer for carrying load. The load carrying container of the present invention is so designed that it accommodates nearly 50 % extra material, and the rubber torsion bar suspension helps in bringing the centre of gravity down and renders more stability to trailer without sacrificing ground clearance. The hydraulically operated disc type brakes working in tandem with the Tractor Brakes avoid accidents due to jack knifing effect.
The present invention is illustrated with reference to the accompanying drawings, wherein numbers indicated in the bracket represent the components of the invention throughout the description. The Table-1 below lists all the components of the system an\d their corresponding reference numerals:

Number Component Number Component
200 Non toppling trailer 140 Linking means
110 Container 144 Master cylinder
120 Rectangular frame 146 Disc brakes
130A Pair of front wheels 150 Draw bar
130B Pair of rear wheels
Referring to Figures 4 to 8, schematic views of a non toppling load carrying trailer system (200), (hereinafter “the trailer (200)”), in accordance with the present invention are shown. The trailer (200) comprises of a rectangular frame having a frontend and a rear end. At least one pair of front wheels (130A) is fitted to the front end of the rectangular frame (120), wherein two wheels of the pair of front wheels (130A) are linked with a rubber torsion bar suspension (140). The pair of front wheels (130A) is fitted with a steering system and a braking system. At least one pair of rear wheels (130B) is fitted to the back end of the rectangular frame (120), wherein two wheels of the pair of rear wheels (130A) are linked with a rubber torsion bar suspension (140).
A container (110) is fitted on a rectangular frame (120) for carrying load. Base of the container (110) is designed in such a way that it occupies the space between the wheels (130A, 130B) and above the frame (120). The container (110) provides 50% more storage space than the container (10) of the existing art, which is fitted fully above the wheels. The RTB suspension (140) brings down the centre of gravity as it is located at the center of axle. Use of RTB suspension makes it possible to accommodate higher (up to 50%) volume in the container (110). Further, the RTB Suspension (140) absorbs about 50% shocks and the tractor can travel at a faster speed and without a serpentine movement.
In another embodiment, the trailer (200) comprises of an independent brake system providing wheel disc brakes (146). The master cylinder (144) is suitably mounted on draw bar (150). Disc brakes (146) avoid problems arising out of mud ingress and minimize the risk of jack-knifing of the trailer.
The improved design of the container (110) brings down centre of gravity, improving the stability of the trailer. The container (110) is suitable for tipping trailer - quick unloading of material from the trailer. Moreover, it is most useful for combined harvester (sugarcane cutting) as a tipping trailer.
Advantages of the invention:
• Risk of accidents due to toppling, jack knifing, overturning reduces significantly.
• The non toppling trailer (200) of the present invention allows carrying more than 50% additional load which in turn saves fuel significantly.
• Zero maintenance on suspension system.
• Extremely good stability of trailer (110) at greater speeds.
• No serpentine movement of trailer (110). No risk to passersby.
• Reduction in transportation time due to enhanced speed.
• Since rubber torsion bar suspension system (120) of the non toppling trailer (200) absorbs 50% extra shocks as compared to leaf spring suspension system (20) of the existing trailer (100), maintenance cost comes down automatically.
• The non toppling trailer (200), when used with the tipping arrangement, unloading time is saved substantially.
